Efficient use of sawdust as a fertilizer. Using sawdust in a summer cottage How to prepare fresh sawdust for mulching

For some crops, mulching is an essential agronomic practice of the growing process.

With its use, plants are more protected from freezing in the winter, from heat and heat in the summer.

Mulching inhibits weed growth and makes the soil less susceptible to excessive evaporation. Fruits, due to the lack of contact with the soil, are less damaged by diseases.

When applying this prim it is important to choose the right material for this important procedure. One option is sawdust mulching.

The use of sawdust has several advantages over other materials. These benefits are as follows:

How to prepare sawdust for mulching

For soil mulching, only sawdust is used, which can be taken at any wood processing plant or made by yourself using wood and a saw.

It is advisable to use them from deciduous trees, as fresh coniferous sawdust strongly oxidizes the soil.

Particles of this material can be different sizes, and, consequently, the properties of the mulch will be different.

It is desirable to use medium-sized sawdust for mulch. Very fine particles often cake and form a crust or lumps on the soil surface. The large particle size of wood shavings is also undesirable for use as a mulch on tender garden plants.

But for mulching trees and shrubs, a large size of sawdust would be the best option.

Many summer residents are interested in the question of whether it is possible to mulch with fresh sawdust? A more favorable type of mulch for plants is half-rotted sawdust. This is due to the fact that fresh sawdust contains little nitrogen (0.5%) and is forced to take it from the soil.

Therefore, it is best to use rotted material from two years ago, or artificially accelerate its maturation by enriching it with nitrogen.

To do this, sawdust is poured with the following solution: 200 grams of urea diluted in a bucket of water. For the best impregnation the filled sawdust is periodically mixed.

Most gardeners prefer to recycle sawdust before using it in the compost pit.

How to mulch with sawdust, the nuances

Mulching the soil with sawdust should be carried out only after careful processing of the beds.

It is necessary to weed the weeds, trim the mustache and shoots (if it concerns strawberries or raspberries).

Some gardeners cover the beds with thin paper before mulching, this more thoroughly protects against the appearance of weeds.

The layer of sawdust is usually from 3 to 5 centimeters.

In case of mulching with fresh sawdust it is necessary to apply nitrogen fertilizers. Since they oxidize the soil, it is recommended to apply them with ash. A good effect gives the simultaneous use of the drug Baikal EM1.

When to mulch

Mulching with sawdust is used in autumn to protect plants from freezing. This method is suitable for perennial flowers, strawberries, shrubs and vegetables planted in winter.

But you need to remember that sawdust is a rather hygroscopic plant, and having absorbed moisture in the spring, they thaw for a long time, forming an ice crust. Therefore, such a shelter may not be suitable for all plants. For example, it is not advisable to use it on roses.

In spring, the procedure is carried out after careful processing of plants, removal of the old mulch cover, or digging it with soil.

Mulching strawberries with sawdust should be done before flowering. By the end of summer, due to exposure to sunlight, rain and wind, there will be very little sawdust in the beds.

In summer, mulching plants is highly undesirable. Since this will not allow perennials to properly prepare for winter.

What crops can be mulched with sawdust

Trees, shrubs, flowers are mulched with sawdust.

This material is used to cover beds with vegetables and berries; for this, the space between the beds is sprinkled with sawdust to reduce the growth of weeds.

For decorative mulching of flowers, trees or shrubs, sawdust of large fractions can be dyed in various colors. This gives a unique splendor to landscape design.

Use this type of mulch for growing vegetables such as carrots, potatoes, onions, cucumbers. On carrots, the smell of sawdust prevents the appearance of carrot flies. To increase the yield of potatoes, mulching the distance between plants with sawdust after hilling gives a good effect.

In combination with nitrogen fertilizer, such a layer provides best growth cultures.

Mulching with sawdust is inexpensive and effective method increasing crop yields, maintaining and improving soil fertility, as well as giving the garden and garden an aesthetic look.

In search of cheap fertilizer, most landowners line up for sawdust, which is considered natural and very useful top dressing. What is their surprise when, instead of flowering and smelling plants, they receive not only a decrease in yield, but also the complete death of crops. This is not surprising, because everything must be approached wisely. After reading this article, you will learn from which side to approach the issue of fertilizing the land with sawdust.

Sawdust in compost sauce

If you put fresh sawdust without any particular treatment directly under the plant, then soon you will see how it begins to die. Why? Soil bacteria did their best here, which, when “working” on wood, suck out nitrogen from the fertile soil, which is a vital element for plants.
Fresh sawdust contains an increased amount of various resins.

Penetrating into the soil, they not only destroy the fertile layer, but also poison it for future plants.

Some summer residents are sure that they can make valuable fertilizer by accumulating mountains of sawdust in one place. This is wrong. It can take years for one small pile to rot. This is explained quite simply. The process of decay is under the influence of moisture, and sawdust practically does not let it through. The bottom of the pile will always remain dry. Even after many years, several kilograms of sawdust can be found at its bottom, which could retain all their original properties.

The correct sawdust compost can be made according to the following recipe:

A pile must be formed through layers of sawdust, wetting each of them with urea (200 g per 10 liters of water);
The pile is covered with a film in the form of an airtight dome;
Every 2 weeks, the layers must be shoveled so that they are enriched with oxygen;
After the compost sawdust turns black, it can be used as fertilizer.

You can use another recipe for making compost from sawdust with the addition of fertilizers:

Still, sawdust will need to be formed in layers;
Pour all layers with plenty of water, sprinkle with lime and add a solution of fertilizers. To prepare the dressing, it is necessary to take, based on 10 kg of sawdust, 150 g of lime, 130 g of urea, 70 g of potassium chloride, 10 g of superphosphate. The height of the heap can be made up to one and a half meters, periodically maintaining its humidity.

Instead of chemical fertilizers, you can use chicken manure at a rate of 1: 1 with sawdust. In such compost heap feel free to throw away food waste, straw, weeds, etc. The ripening period of such compost is about six months.

Sawdust compost with nitrogen flavor

As noted earlier, when the soil is fertilized with fresh sawdust, nitrogen is absorbed from the soil. This is easy enough to avoid by doing just 2 simple steps:

It is necessary to sprinkle wood shavings with nitrogen-containing fertilizer at the rate of 20 g of the mixture per 1 kg of wood;
Put the resulting substance on the ground and carefully dig everything.

It is important to remember that if you are preparing beds for tomatoes, potatoes or carrots, then it is better to do this procedure in the fall. If your goal is to grow cucumbers, pumpkins or cabbages, a mixture of nitrogen-containing fertilizers and sawdust compost is best combined with manure, fertilizing the ground in the spring.

Mulch filled with sawdust

Sawdust is great for mulching the soil. There are several reasons for this:

Perfectly retain moisture;
Does not contain weed seeds;
Weed grass hardly breaks through a dense layer of sawdust.

Mulching the earth with sawdust is not only useful, but also very beautiful. You just need to know the right recipes.

Here is one of the options for making sawdust mulch:

Sawdust is soaked in a strong solution of potassium permanganate, which gives them a beautiful color;
Well-ground branches are also stained with potassium permanganate;
We mix sawdust and branches, carefully lay them under the trees.

Be careful when choosing sawdust, because not all are environmentally friendly. For example, chipboard chips contain various carcinogens, which are hardly washed out of the soil and penetrate into the fruits of vegetable crops.

If it is necessary to make the earth loose, use sawdust for the garden, the benefits and harms of which have been studied. experienced gardeners. But it is not recommended to use fresh sawdust. First they need to be prepared. To do this, add urea or mullein infusion, cover with polyethylene, and then mix from time to time to speed up the process of overheating.

After a couple of weeks, the shavings are ready to be used as fertilizer. Much has been written in the reviews about the benefits or dangers of sawdust in the garden. Experienced summer residents claim that they take nitrogen from the soil, and therefore from plants. They say that you should not use fresh sawdust in the garden, as the plantings will begin to wither.

The benefits of sawdust in the garden

Plants need loose soil to thrive. The addition of rotted sawdust makes the earth a favorable environment for planting garden plants, the roots of which are obtained enough moisture and oxygen. The use of sawdust allows you to get rid of the crust in the dry season.

They contain a large amount of fiber, essential oils and active substances. The material is successfully used to eliminate soil moisture. To do this, ditches are dug in the aisle and sawdust mixed with lime is poured. Their regular use improves the composition of the soil, reduces the number of weeds, and increases productivity.

What is their secret and how do they work?

They form a natural ecosystem for plants in the garden. It is important to use sawdust that has not been chemically treated or contaminated. Otherwise, they will become a real poison for horticultural crops. If rotted sawdust is used as mulch at the beginning of summer, then by the end of the season, as a result of loosening and the activity of earthworms, they will mix with the soil.

A thick layer of sawdust spread over the surface of the earth during the rainy season prevents moisture from evaporating from the soil surface. This in a negative way affects the state of fruit and berry crops.

Basic rules for the use of sawdust

Wood shavings are great for mulching the soil. They are sprinkled with a thick layer after planting seedlings.

Advantages:

the weed disappears;
soil moisture is maintained;
insect protection;
the soil remains loose;
favorable conditions for the growth of bacteria.

Mulching

Do you need sawdust for the garden in the fall? Everyone is trying to figure out their benefits and harms. As a rule, the soil is mulched for the winter. To do this, fresh sawdust is mixed with peat or manure and scattered on the beds. During the winter, the wood decomposes and becomes a nutritious substance. In the spring they dig or loosen the soil.

High warm beds

The benefits and harms of sawdust for the garden should be studied by every summer resident. How to make multilayer in the bottom of the plot high beds? For such purposes, it is convenient to use sawdust. Upper layer fertile soil is removed. They build a side, cover it with a film to preserve moisture in the garden. A trench is formed and filled with straw, hay or grass. Further, sawdust soaked in urea is placed on top of this, then a layer of organic residues is placed and everything is completed with a fertile layer of earth.

Mulch for strawberries

benefit or harm coniferous sawdust bring in the garden? Sawdust, used as mulch under strawberry bushes, protects them from contact with the soil. Thanks to them, the berries are protected from the effects of gray rot. For this purpose, fresh coniferous shavings treated with urea are used. Mulch is applied in the fall to protect the strawberries from freezing and create a barrier to many weeds. Weevil is repelled by pine sawdust in the garden, the benefits or harms of which are learned by practical experience.

Sawdust in a greenhouse and greenhouse

sawdust - useful fertilizer for soil in a greenhouse. They are sprinkled with plant residues and manure, which warm up in the spring and quickly overheat. The air permeability of the soil increases, it becomes loose and nutritious. In autumn, straw, mowed grass and tops are laid out on the garden bed.

Spring add fresh manure and sprinkle with lime with sawdust, mix with a pitchfork. Then lay the soil mixed with ash and mineral fertilizers. To increase the speed of heating, pour boiling water.

Sawdust for early potato harvest

So, why do we need sawdust for the garden? What are their benefits and harms? The use of sawdust helps speed up the potato harvest. Choose tubers early varieties and grow in the light. At the bottom of the boxes, 10 cm of sawdust is poured, tubers with sprouts are laid out and sprinkled with moistened sawdust. Set aside for 2 weeks.

Features of substrate care:

the optimum temperature is not higher than +20 ° С;
sufficient moisture.

Before planting, the soil is covered with a film to warm up. Sprouts 8 cm high are watered with complex mineral fertilizer and planted in prepared holes. First, the potato planting is covered with straw or hay, and then with a film.

Sawdust and plant insulation

So that the sawdust does not get wet, they are stuffed into bags. Then spread around the plants. If sawdust is poured around the plant and not covered, then they will get wet and turn into an ice crust in winter. Rodents also like to hide in them, so be sure to cover them with polyethylene.

Sawdust for seed germination

Seeds are comfortable in moistened sawdust, but if the plant is not transplanted on time, it will die.

The germination technology is as follows:

Sawdust is poured into the container and the seeds are laid out.
Sprinkle with a thin layer of sawdust.
Cover with polyethylene and clean in a warm place (+25 ... + 30 ° C).
As soon as shoots appear, the container is cleaned in a cool place.
Remove the polyethylene and sprinkle with soil.
Dive when the first true leaf appears.

This technology can be applied when germinating any kind of seeds.

DIY fertilizer

Nutritious compost can be prepared in 4 months. Dense polyethylene is spread on the ground, shavings, weeds, foliage are poured. Add 200 g of urea and pour 10 liters of water or mullein. Cover with polyethylene on top to create greenhouse effect. Under the influence of sunlight, the process of reproduction of microorganisms begins, and the sawdust quickly rots. The main thing is to monitor the humidity inside the heap and mix it periodically. Vegetables and raspberries can be mulched with half-ripe sawdust.

A month later, the sawdust that has percolated is ready for use in the beds. The constant use of such a fertilizer will make the soil loose, similar in consistency to the one sold in flower shops.

Cons of using sawdust and cautions

So, we have already found out whether fresh sawdust in the garden brings benefit or harm. If sawdust is introduced without waiting for the moment when it is completely overheated, then the wood will take some of the nitrogen from the soil for the decomposition process, as we discussed above. And also the acidity of the soil may increase, the growth of beets and cabbage will slow down.

Before the onset of winter, it is not recommended to cover the beds with a thick layer of sawdust, since the layer will begin to overheat from below, and no changes will occur from above until the onset of spring. Spruce or pine shavings contain a lot of resin, which garden plants do not like. Sawdust generated during construction work may contain chemicals. Therefore, they are used with caution.

Every summer resident knows that plants need nitrogen, phosphorus and potassium for full development. These are the three main macronutrients, the deficiency of which significantly affects appearance and yield of plants, and in advanced cases can lead to their death. But at the same time, not everyone understands the importance of other macro- and microelements for plant health. And they are important not only in themselves, but also for the effective absorption of the same nitrogen, phosphorus and potassium.

garden strawberry, or strawberry, as we used to call it, is one of the early fragrant berries that summer generously endows us with. How we rejoice in this harvest!

February and early March Sun rays become more active, and the plants are not yet ready for new conditions.

“Each vegetable has its own time”, and each plant has its own optimal time for planting. Anyone who has experienced planting is well aware that the hot season for planting is spring and autumn. This is due to several factors: in spring, the plants have not yet started to grow rapidly, there is no sweltering heat, and precipitation often falls. However, no matter how hard we try, circumstances often develop in such a way that landings have to be carried out at the very height of summer.

Summer is associated with beautiful flowers. Both in the garden and in the rooms you want to admire the luxurious inflorescences and touching flowers. And for this it is not at all necessary to use cut bouquets. In the range of the best indoor plants many beautiful flowering species. In the summer, when they receive the brightest lighting and the optimal duration of daylight hours, they are able to outshine any bouquet. Short-lived or just annual crops look like living bouquets.

Fertilizer is not only chemical substances specially synthesized. To feed the soil when growing crops, waste from various industries can be used.

It can also be sawdust - as a fertilizer, they can be used both in the greenhouse and in the fields. This option is a simple and cheap recharge for the soil.

1 How do wood chips affect the soil?

D Wood shavings are a natural organic material, in which useful elements still remain even in the form of sawdust. Rotting, they release carbon, which has a beneficial effect on the microflora.

Mixed with the soil, sawdust makes it looser and lighter, improves air permeability, and at the same time does not retain moisture. As a result, the soil becomes more like. It will be easier to develop the root system of crops in it.

First of all, it is useful for such areas:

"tired" lands that were actively used for growing any crops (even if the cultivation was carried out according to all the rules, with);

soils with poor fertility.

The soil after adding chips is less prone to drying out, and in dry weather a crust does not form on its surface.

1.1 Pros and cons of application

Such a fertilizer material has the following advantages:

cheapness and ease of obtaining (sawdust can beliterally for a penny to buy in any woodworking shop,or even pick up for free if you need a small quantity);

P growth of application;

improving the condition of poor soil, simplifying the development of the root system;

soil loosening.

There are also cons:

"fresh" oxide sawdust t soil, so apply their necessary in moderation, only after preliminary preparation (about preparation - below);

shavings are not the "main" fertilizer - it is only an auxiliary material for the soil.

1.2 Using sawdust in the garden (video)

1.3 For which crops can it be used?

Sawdust composition can be used for any type of planting:

"garden" crops, from potatoes to strawberries;

trees (fruit, berry);

agricultural crops grown in the fields.

Use this fertilizer it is possible as outdoors(in the garden, on the field, in the garden), and in greenhouses and greenhouses.

In the fields, this method of fertilization is practically not used, and if it is used, then infrequently, rather as an exception. Crops grown in large volumes are usually fertilized with specialized preparations. And sawdust is rather one of folk remedies, from the "arsenal" of amateur gardeners.

2 Which sawdust is suitable for fertilizer?

Before using fertilizer from sawdust, it is worth remembering the basic rules:

Pine shavings - not suitable. Pine (and others coniferous trees) contains a resin that slows down the decomposition of wood. So - all the benefits of the application will come to naught.

"Fresh" sawdust should be used with the utmost care (so as not to overdo it with the amount), and separately - it is better not to use it at all. The reason is that fresh wood will oxidize the soil.

The decomposition of wood in the ground contributes to the fact that the amount of nitrogen in it will decrease. Therefore, crops that will grow on it may be deficient in this element.

If shavings were stored near/under brush weeds- as a fertilizer, it can only be used after processing by hot composting. This requires watering sawdust hot water(hot 60 degrees), quickly cover with polyethylene and leave for a few days.

The conclusion can be drawn as follows - for safe use fit:

Sawdust from non-coniferous trees.

Overripe shavings (which lay on fresh air as long as possible, ideally not less than a year). Its color will be darker than fresh. The darker - the better (that is, the longer they rot - the better).

Mixing with other types of fertilizers.

2.1 What can I mix with?

It was mentioned above that sawdust is best used by applying it along with something else to make a mixture. "Recipes" can be:

2.2 Use as mulching material

P use sawdust can be used as mulch- This is true for any plants in the garden.

This is done at the beginning of summer (no later than June). Whole land plot(on which crops will grow) is covered with a layer of sawdust, 2-3 cm thick. This preparation will prevent the appearance of weeds, make the earth looser, and help retain moisture in the soil.

After harvesting, the soil needs to be dug up. In this case, the sawdust is mixed with the soil, and on next year will already turn into fertilizer for the next plantings.To neutralize the oxidation of the soil (from the “clean” wood chips in it), it is recommended to sprinkle it with lime flour.

WITH too much sawdust for mulching should not be used. At the end of the season, after digging up the site, they should not remain on the surface. Otherwise, next spring they will only be a hindrance: they will prevent the soil from freezing.

WITH The preparation process looks like this:
Fertilizer will be ready in 10-14 days.

2.3 Application in greenhouses/greenhouses

P When preparing soil for greenhouses / hotbeds, it is important to use shavings so that the soil keeps the temperature more stable.

It should be mixed with finely chopped leaves and grass. Moreover, if the manure is taken fresh, then the sawdust must be fresh. And vice versa: if the manure is rotted, the sawdust should also be taken already rotted.

2.4 About the benefits and rules of use (video)

2.5 Application on the beds

AND using sawdust as a fertilizer, maximum efficiency can be achieved when growing strawberries (strawberries)and potatoes. They will also be useful in vegetable gardens located in the lowlands.

To protect planting from drought and weeds, shavings can be used not directly under the plant, but nearby. To do this, furrows are dug along the beds (25 cm deep), into which sawdust is poured. They will play the role of a kind of barrier that will not allow weeds to enter the plant and will not release water. rotten, wood chips will give useful elements to the soil, after a year or two after instillation, it will also turn into fertilizer.

It is most effective to use sawdust in the beds in the following way:
