Absolutely all agricultural crops are demanding on the nutritional value of the soil, that is, its fertility, because with each new crop the soil is depleted and requires additional fertilizing.
Organic and mineral fertilizers are used to restore the fertile properties of the soil.
Organic group is the main pre-sowing period, it is organics that contribute to better seed germination and plant development.
But the mineral group is an auxiliary feeding element, which is necessary in cases where organic matter runs out of its potential.
Organika improves the natural and climatic properties of the soil, making it loose and saturated with all the necessary substances and carbon dioxide, thereby accelerating microbiological processes in the soil structure.
Types of organic fertilizers
Manure as organic fertilizer
The simplest and most accessible type of organic fertilizer is manure. This element increases the amount of useful and loose humus in the soil composition.
Manure is stored for the purpose of obtaining high-quality fertilizer in special shoulders, in which manure layers are covered with peat and straw.
Peat and straw do not allow future fertilizer to evaporate large quantities of nitrogen, which has a great effect on the future yield of all crops and vegetables.
The durability of manure ranges from three to five years.
No less effective organic fertilizer is humus, which is obtained from decomposed manure and foliage, the so-called compost. Most often it is used in the cultivation of vegetable crops, especially during the cultivation of resistant and strong seedlings.
Liquid organic fertilizers
This type of fertilizer includes urine of animal origin and slush, which is formed during the decomposition of manure. They are very rich in nitrogen and potassium.
They are used in practice in a diluted form in the proportion of 1/10, where water prevails. Liquid fertilizers are especially useful for vegetable and fruit and berry crops. Mostly liquid fertilizers are applicable at the moments of transplantation, ovary, flowering and fruiting.
The use of organic matter in liquid form is not recommended in hot dry weather. Fertilized roots or foliage by spraying with a sprayer. Fertilizer is held in the evening.
This product is a structure of the remains of bog plants not decomposed under conditions of high humidity due to insufficient air penetration into the soil. The nitrogen content in peat is twice as high as in manure.
This organic fertilizer is mainly applicable for vegetable crops and potatoes. Litter is rich in nitrogen, phosphorus and potassium. Fresh bird droppings are mixed with peat or straw, and then dried and crushed to a powdery mass. It is used in the preparation of various fertilizer composts.
Green mass of leguminous crops
The legume family crops are excellent nitrogen accumulators, therefore they are often used as organic fertilizers by plowing green mass, as a result of decomposition of which the soil is enriched with nitrogen. This method of fertilizer is especially common on sod-weakly podzolic soils.
Often at home, gardeners use organic matter that is not too concentrated, such as ash, it does not include the necessary amount of nutrients, and it must be mixed with other organic or mineral components.
The combination of mineral and organic elements creates the so-called organic-mineral fertilizers, otherwise they are called humic.
In cases of improper care of the soil, this type allows you to put in proper order the balance of the contents of all the necessary nutrients in soil that is uncultivated and fertilized with fertilizers.
Organic fertilizers are produced only after thorough chemical analysis of the soil to be treated.
How to apply organic fertilizer?
Organic fertilizers in a liquid state are applied under the root system of crops and vegetables, and in the consistency of powdered and crumbly mass they are distributed over the surface of the soil, which is subsequently plowed up or dredged. At home, a bayonet spade is used for this, but an organic fertilizer spreader is applicable for farms for this purpose.
The acquisition of fertilizers in gardening supermarkets is not a problem today. It is on the purchased packages that the rates of application of organic fertilizers are always indicated. They should be adhered to, since production-type fertilizers can be either single-component or complex, calculated specifically for use for a particular type of crop.
