Inexpensive and affordable natural material - sawdust. They can be purchased at the nearest sawmill, obtained at their own site during construction, sawing firewood. Farmers have found many ways to benefit from this waste. But do not forget that they can be harmful. Further in the article let's take a closer look at aspects such as the benefits and harms of using sawdust in the garden. As well as how to fertilize or treat the beds.
Scope of use of sawdust in the country or garden
Sawdust and shavings are sometimes burned, receiving mineral fertilizer - wood ash. But in this way valuable organic matter disappears, the bulk loose substance disappears. More profitable to do differently:
- Bookmark in the soil and greenhouses.
- Neutralizer of harmful substances.
- Temperature insulator.
- Pest repeller.
- Additive to seedling soils.
- Substrate for mycelium, germination of seeds and tubers, forcing flowers and greenery.
- Environment for winter storage of rhizomes and tubers.
- Covering garden paths.
- Litter in livestock and poultry, in a dog kennel.
- A filler in a country toilet.
- Material for stuffing garden scarecrow, garden furniture and pillows.
- Building materials (insulator, insulation, filler for opilkobetona).
- Fuel in heating boilers.
- The source of smoke in the smokehouse.
Varieties of small wood waste
Small waste from sawing wood is divided into chips, large and small fractions. Differences are also available by type of wood: from coniferous or hardwood. Sometimes differences are important, for example: deciduous waste rot faster; conifers are not suitable for smoking products, etc. But the value is any organic. Before use, it is desirable to handle sawdust.
Benefit and harm
- For humans and the environment is dangerous the presence of such impurities as creolin, chemical oils, paint particles, glue, gasoline. That is why it is necessary to take the products of processing of pure wood, and not chipboard or sleepers.
- Resin substances inhibit seed germination and plant development. This deficiency is neutralized by scalding the substrate with boiling water, as well as during composting.
- Intact organic matter (when introduced into the soil and on its surface) begins to decompose by microorganisms, which heavily consume soil nitrogen. Because of this, plants are starved for nitrogen - they turn pale, they develop worse. Therefore, it is recommended to put only rotten sawdust into the ground, and when mulching with fresh, spice it with nitrogen fertilizer.
- Sawdust compost acidifies the soil. It is necessary to alkalize simultaneously (in the fall - with lime, in the spring - with dolomite flour, ashes).
- Rustic sawdust soil dries out too quickly. It is necessary to observe the recommended proportions of the components, to monitor the regularity of watering.
Sawdust mulch is a cheap and convenient option. She covers at the cottage:
- surface ridges with vegetables and strawberries
- soil in raspberry field, flower beds
- tree trunks in the fruit garden
Layer thickness can be from 4 to 20 cm.
Mulch acceptable and fresh sawdust. They are pre-cooked: impregnated with a strong solution of nitrogen fertilizers. For this, 3 buckets of mulching material are poured with 10 liters of water, where a quarter of a kilogram of urea or nitre is dissolved. It is best if this mixture is allowed to stand for a couple of weeks before being mulched (covered with polyethylene), after which it can be poured over the beds. Mineral fertilizers can be replaced with fresh manure or manure (2 liters), but this mulch will not work with strawberries and some vegetables (for hygienic reasons).
Advantages of sawdust mulch
- the material is not littered with weed seeds
- gradually mulching, mulch enriches the soil with organic matter
- moisture is saved
- no soil crust and erosion
- roots are insulated, temperature drops are smoothed
- comfortable to useful soil inhabitants (microorganisms, earthworms)
- it is difficult for some pests
- there is no dirty spray in rain and watering - cleaner products and fewer diseases
- weed growth inhibited
- ridges, garden, flower beds look well-groomed and beautiful
How can compost be fertilized
The best option for disposal of sawdust - competent composting. Just poured in a big pile, they will be spent several years (especially from coniferous trees). Rot is accelerated by layer-by-layer mixing with substances such as
- grass humus
- dolomite flour, ash.
Mass is regularly shoveled and shed with water, as well as mineral fertilizer solutions, herbal infusions, and biopreparations (Baikal, Florumb Super, Shining). Compost maturation usually lasts from six months to two or three years. The minimum waiting period is 2 months.
Bookmark in soil and greenhouses
Sawdust compost is recommended to be applied to the soil for autumn digging (5-15 liters per 1 sq. Meter), after lime fertilizers. Well-rotted organic matter is used in the spring - they are put under digging, in the wells and landing pits.
Small wood waste is also used when laying biofuels in greenhouses and greenhouses. They are mixed in: fresh sawdust to fresh manure, rotted to rotted (in a ratio of 1: 1).Use of sawdust in greenhouses
Neutralizer of harmful substances
A fresh mass of small wood waste serves as an ambulance in case of emergency. It is added to the ground if a surplus of nitrogen and other fertilizers is noticed. So the plants will avoid fattening, accumulation of nitrates and harmful salts.
Podkiditel on beds in a garden
Freshly sawdust is useful for planting and mulching of plants that love the increased acidity of the soil (hydrangeas, rhododendrons, azaleas, heathers, blueberries).
Pine sawdust as a dehumidifierCompost from sawdust
Fresh sawdust can absorb the amount of liquid that is 5 times larger than their volume. They are well filled with drainage ditches, paths between high ridges in wetlands.
In regions where winter temperatures are low, with dry sawdust, the root zone and branches of bushes (grapes, hydrangea, rose, clematis), planting of winter garlic and perennial flowers (lilies, irises, chrysanthemums) are covered from freezing. In order to avoid drowning, the shelter is produced when the onset of sub-zero temperatures, and the opening - in the spring early. To protect against moisture, a waterproof material is placed on top (polyethylene, roofing felt, etc.).
Some fruit crops bloom very early, and the ovaries freeze slightly. If the basal zone is filled with a powerful sawdust layer, the trees and shrubs will wake up later. Flowering will move back to a more comfortable time.Rose bushes sprinkled with sawdust for the winter
Pest repeller in the garden
Small wood waste is impregnated with tar or gasoline, laid out to scare away rodents, onion and carrot flies.
Adding spiny sawdust makes it difficult to move snails and slugs. The resinous aroma partially protects plants from the attack of beetles (Colorado, raspberry, flower beetle, weevil).
Additive to seedlings
A soil substrate containing from 10 to 50% refrained sawdust compost is recommended for
- seedlings of vegetable and flower crops
- rooting cuttings and strawberry whiskers
- growing seedlings with a closed root system.
Other components of this soil are garden soil, peat, some sand. Loose soil requires frequent watering or special additives that retain moisture (hydrogel, vermiculite, coconut substrate).
Use of the substrate as fertilizer
Cucumber seeds (as well as squash, pumpkins, melons and watermelons) are germinated in fresh small sawdust, and seedlings are kept. The substrate is poured boiling water, then the water is immediately drained. The procedure is repeated twice to wash away the resinous substances. The warm wet mass is laid out in a layer of 6 cm, and dry seeds are placed in it to a depth of 1.5 cm (with a distance of 3 cm from each other). Crops are covered with film and placed in a warm place. Shoots "shoot" after 3-4 days. Seedlings are ready for planting in two weeks.
In sawdust you can produce forcing the green onions, tulip flowers. Substrate must first be shed with boiling water, to flavor with complex fertilizer with a predominance of nitrogen. Similarly, germinated before planting tubers of potatoes and dahlias.
The middle fraction of the crushed wood of deciduous trees is used for artificial breeding of mushrooms such as oyster.
Environment for winter storage of rhizomes and tubers
In the fall, flower growers dig up dahlia tubers, callas and begonias, cannes rhizomes. They are stored in a cellar or a refrigerator, sprinkled with dry fresh sawdust. Resinous components inhibit rotting.
Farmers are zealous and creative people. They are able to convert waste into income, especially when it comes to organic. As you can see, the use of pine or any other sawdust can benefit in capable hands.
