To restore the mineral composition of the topsoil after growing crop used a number of methods.Lead is a fertilizer.This is done primarily to ensure the three major plant nutrients: nitrogen, potassium and phosphorus.In this regard, highly effective fertilizer superphosphate.
its application improves the root system of plants, maintain or restore their healthy growth and development, slowing the oxidation and enhances the regenerative processes in soils.Fertile layer enriched with a sufficient amount of nitrogen and phosphorus, as well as potassium, calcium, magnesium and sulfur.A direct consequence of this is to increase yields and improve quality.
superphosphate fertilizer effectively their complex effects.Its main component is phosphorus, followed by nitrogen.For neutralization of excess acidity soil corresponds calcium.Magnesium - an essential element for growing potatoes.Sulfur helps to grow legumes, grains and oilseeds.
According to the method of production and the content of phosphoric acid superphosphate are single and double (sometimes triple).Produced they powdery or granular form.
Simple superphosphate contains from 14 to 19.5% of phosphorus;double its correspondingly twice.It is included in the fertilization of the soil and plants.During the spring and autumn digging the beds it paid 100-200 g superphosphate per 1 sq.m.This fertilizer is used for liquid feeding: 12-25 g dissolved in 10 liters of water and infuse for two or three days.
Lack of simple superphosphate - a significant content of calcium sulfate (gypsum), reaching in its share to 40%.In fact, for gardeners, gardeners and farmers, he - transport ballast.Although superphosphate fertilizer can sometimes be useful because of the calcium sulfate, for example, in the case of soils poor in sulfur, and if there is, plants that consume large amounts of sulfur.However, most of the gypsum is practically useless for plants mineral.
Granular superphosphate has a distinct advantage over the fertilizer produced in the form of a small fraction.The fact that a powdered superphosphate in soil (especially if it is acidic) enters a state in which all of its nutrients available to plants.And the more carefully it is mixed with the soil, the more useless it becomes.Superphosphate granules of 1-4 mm not have this drawback, but because they contain phosphoric acid, better and longer absorbed by plants.Fertilization in this way has good physical properties: it does not cake and well scattered on the site.
superphosphate fertilizer effectively used not only directly to the plants, but also as an additive to fresh bird droppings.This is done in order to bind therein ammoniacal nitrogen into involatile forms and prevent its loss during storage.One kilogram of superphosphate added to the compost keeps approximately 400-500 g of nitrogen.
