Poultry manure is an excellent organic fertilizer for all plants, and quail guano is especially useful.
But keep in mind that it is a very highly concentrated fertilizer, therefore, if it is incorrectly applied in its pure form, it can simply destroy the plants ...
* For composting, moisture-absorbing plant residues: leaves, straw, sawdust, peat are laid out on an elevated flat area with a layer of 30 cm. Poultry droppings are poured on top with a layer of 20 cm, and then again peat or sawdust and again droppings: in this way they form a pile up to a meter high (if the components are dry, then they are moistened when laying).
To eliminate the unpleasant odor, the pile can be covered with straw and a 20 cm layer of earth. In the warm season, the compost will be ready in one and a half to two months.
When composting, it heats up, and most of the pathogenic microorganisms, as well as helminth eggs and weed seeds, die in it. It is better to introduce such compost if you do not scatter it over the site (since nitrogen evaporates), but embed it directly into the soil at the site of future ridges - into furrows or holes that can be prepared in the fall. If you add fresh compost in spring, the ripening of the crop will slow down due to the lush vegetative growth of plants. Therefore, in the spring, it is better to add only seasoned, completely rotted compost.
Putting droppings in the fall for vegetables follows from the calculation: dry 100-300 g per 1 square meter, raw - 300-900 g.
The best result is given by feeding with poultry droppings: for introduction into holes or furrows, you will need 40-100 g of raw droppings, dry - 20-50 g per 1 sq.
Liquid dressings are even more effective. To do this, 1 kg of raw manure (or 0.5 kg of dry manure) is diluted in 10 liters of water and introduced into the soil by 1 liter every 7-10 days until the vegetables ripen. It is very good when the droppings wander in the water for about 3 days before application.
It is undesirable to keep the droppings in a pure form, since a significant part of the nutrients, in particular nitrogen, is lost. Losses are especially high during freezing in winter and subsequent thawing in spring (up to 40%).
The drier the droppings, the greater the concentration of nutrients. If in a wet state poultry manure as a fertilizer contains up to 2% nitrogen, 1.5% phosphorus, up to 1% potassium, then in a dry state it is two to three times more.
The lives of hundreds of locals living along the Peruvian coast in South America depend entirely on guano, bird droppings that have decayed naturally and are a valuable natural fertilizer:
Eng.: Quail droppings guano. Suom.: Viiriästen ulosteet. Sven.: Vaktel tappar.
In terms of chemical composition, quail manure is three to four times richer than cattle manure. But you cannot use it in its pure form, as this will lead to burns, disease and death of plants.
Nutrients in it are in a combination favorable for plants and soil microflora, quickly dissolve in water and are easily absorbed, so even today this fertilizer is indispensable, especially among supporters of organic farming.
In terms of its effect on the yield in the year of application, poultry manure is almost identical to that of mineral fertilizers, but due to the property of gradual release and high concentration of organic components, it continues to affect the yield in the next two to three years, that is, it has a prolonged aftereffect!
It should be noted, however, that the ratio of nutrients in the dung is suitable for vegetables with a high potassium intake, in particular, potatoes and some root vegetables. Potassium deficiency can be compensated for by adding wood ash (not stove ash) or completely decomposed compost from plant residues.
The disadvantage of this fertilizer is that the main part of nitrogen in the dung is in the form of uric acid, which, when applied with high doses of dung, inhibits the growth of seedlings and young plants. Gradually, it turns into urea, then into ammonium carbonate, which is easily nitrified in the soil. Therefore, as a result of an overdose, nitrates can accumulate in vegetables.
In addition, fresh bird droppings are toxic to plants due to water-soluble metabolites (waste products of birds), as a result of which direct contact with the plant can lead to burns, disease and death. Therefore, bird droppings should not be introduced when planting trees.
To use poultry manure as a dry fertilizer, it is composted, that is, a filler is added - peat, straw, sawdust, soil and other organic components (in a ratio of 3:1), and then placed in heaps for reheating. Thus, after two to three months, the droppings become safe for plants.
If it is not mixed with plant components, then it is better to use this fertilizer for application to the beds no earlier than a year later (to accelerate fermentation, you can and should use EM-technologies: microbiological agent "Baical", etc.).
