Sawdust for loosening soil, composting and mulching
FORGING IN GARDEN - WHY AND WHAT TO USE?
I can not decide such a task so far. On the site we build a bathhouse. As a result, a lot of wood waste is collected - sawdust and shavings.
They can not be thrown out by hand. But I also do not know how to use it correctly. Asked this question to neighbors in the country - so much more confused: some agitate for using them as a fertilizer in the garden and vegetable garden, and others are afraid that it will harm plants. Who is right?

WORD TO THE SPECIALIST
Sawdust and shavings of wood species - valuable materials for loosening of soil, composting and mulching. But! It should be raw materials from an unpainted and untreated wood. Sawdust is specially prepared for different purposes.
For loosening the area sawdust and shavings are kept outdoors for 2-3 months. During this time, a couple of times a heap is loosened so that the composting process begins. Such raw materials are introduced into the soil under planting plants that prefer acidic soil (blueberry - no less than a bucket on the planting pit, rhododendrons, heathers, some conifers).
For use under other plants, sawdust and shavings are folded into the beads, interlacing with weeds and fallen leaves, and withstand at least 4-x months, regularly watering with urea (20 g per 10 L of water) or infusion of Mullein (1: 10).
Again, a bunch 2-3 times shoveled and must be covered with a thick film. Make such sawdust in the soil in the fall under a digging (simultaneously with the addition of dolomite flour) or in the spring, pouring ash. Such use of sawdust helps loosening heavy soils. Similarly, they can be used for the lower layers of warm ridges.
As an integral part of the compost, sawdust is used for pouring layers with food waste, and also for lining the bottom of the compost heap. At the same time, sprinkle the layers with dolomite flour.
Fresh sawdust can be covered with raspberries or blackberries, but once in 2-3 weeks such mulch should be watered with infusion of mullein or green fertilizer, a couple of times per season - daily infusion of ashes (1 L per 5 L of hot water).
In this case, the layer of mulch in 10 cm reduces the amount of weak growth in raspberries and blackberries, and for blueberries such high mulching is a guarantee of maintaining acidic soil reaction. And more: sawdust and shavings of coniferous species must be kept in heaps in 2 times longer than the waste of deciduous crops.

If at hand only fresh sawdust is at hand, they need to be prepared so that nitrogen is not taken over: I spread the film, pour 3 buckets of sawdust on it, 200 g of urea in layers and pour 10 l of water evenly. I cover with a film, crushing it with a load. After two weeks I use sawdust in the country.

From sawdust you can make valuable fertilizer. In a compost heap, lay every layer of sawdust with manure, bird droppings, mowed grass, weed, hay, and kitchen waste. You can add regular soil. Do not forget to spill the layers with water, in which it is desirable to dissolve a handful of complex mineral fertilizers. All this good in compost must lie for at least a year in order to over-ripen, mature. Make ready compost into the soil for digging (in spring or autumn) at the rate of 2-3 buckets on 1 sq.m.

"Right" sawdust
Sawdust is a universal material for use on the site. But you need to use them wisely, otherwise there will be more harm than good. First, sawdust itself is not a fertilizer. On the contrary, they draw nitrogen out of the soil. Secondly, they oxidize the soil, and this property is not suitable for all plants.
I sprinkle sawdust on my site (so that weeds do not grow), as well as mulch the near-stem zone under blueberries, hydrangeas, azaleas - they love acidic soil.
In addition, sawdust not only retain moisture well, but also make the earth more loose. But for strawberry beds, so that the berries are clean and healthy, I take only rotted sawdust that has been lying for at least a year. In addition, I sprinkle sawdust under the plants for the winter to protect the roots from freezing.

A neighbor told me that the seeds of cucumbers, pumpkins and zucchini sow on moss sprouts in abundantly spilled moss (dry it in the autumn on the stove). Does this method have advantages or should you not spend time on it?
#
- I see no advantage in this way. Moss retains moisture well. It is convenient to dive out seedlings from it - the roots are not damaged. However, sawdust of hardwood has the same properties.
True, it is advisable to take those who have lain for about a year and began to decompose. Better yet, buy quality loose peat and not waste time. If you decide to use moss, remember that it is highly flammable, so dry it in places where there is no open fire and high temperature (on the stove, battery). And before use, spill boiling water to sanitize.

All of us, summer residents, want to have an efficient, affordable and inexpensive fertilizer. Sawdust meet these requirements, but do not immediately throw them all the beds. To add the maximum benefit, you need, first, that the sawdust was obtained from solid wood, rather than chipboard, where there is a lot of glue. Secondly, they must be well faded, as evidenced by the dark brown color.
If you just pour the sawdust on the ground, they will pereprevat 7-8, and in dry climates and all 10 years. But the process can be significantly speeded up. On a thick film pour a bucket of sawdust, level and add 200 g urea, abundantly watered. Then again pour a bucket of sawdust, add urea, water, etc. The resulting pile is covered with a film, the edges of which are pressed down with stones, so that the moisture evaporates less. Approximately in 3 weeks sawdust "ripen" so much that they can be brought into the ground.
If the sawdust is used as a mulch, it is not necessary to "ripen" them. Only in the soiled soil it will be necessary to add wood ash, dolomite flour or lime, since fresh sawdust acidifies the earth.

Onions and garlic in the spring were covered with sawdust. Do I need to bring manure, dolomite flour, or something else after the harvest to make the sawdust more likely to rot and not harm the kitchen garden?
#
- It is best to add urea (5-10 g to 1 sq.) Or ammonium nitrate (10-20 g per 1 sq. M.) In this situation. Dolomite flour can be added separately, preferably after urea or ammonium nitrate, as wood sawdust decomposes strongly acidifying the soil.
