In this article it is noted that at the correct combination of manure and mineral fertilizers in a crop rotation its efficiency raises.
Manure at implementation of system of fertilizer possesses a big role. The considerable part of nitrogen, phosphorus and potassium of mineral fertilizers which passes to grain and the straw used on a forage by an animal and in a laying, comes back with manure to the soil.
The correct combination of manure and mineral fertilizers in a crop rotation increases its efficiency. Nutrients of manure are better acquired by propashny cultures with longer vegetative period.
Interrow processing accelerates a mineralization of organic substance, and these plants use the nutritious elements formed at decomposition of manure more fully.
Therefore in a crop rotation it is more expedient for bringing under propashny cultures, and mineral fertilizers – under grain.
When using manure together with mineral fertilizers more big crops from smaller doses of these fertilizers turn out, than at their separate application.
