Ammophos

Ammophos can be brought as the main fertilizer in beds at crops under all cultures and in top dressing — under propashny, commercial crops and vegetables. The lack of this fertilizer is that nitrogen contains in it much less, than phosphorus whereas in practice of most often them bring in identical doses. Therefore for receiving a normal ratio _{of N and P2O5}it is necessary to add a certain amount of unilateral nitrogen fertilizer to ammophos — _{NH4NO3 or CO(NH2) 2}. At introduction of these fertilizers before crops under a cotton and under winter crops they can be used also without addition with nitrogen fertilizers as in this case the lack of nitrogen is compensated by entering of nitrogen fertilizers into top dressing

Ammophos can be applied directly and as priposevny (ryadkovy) fertilizer under a cotton, potatoes and grain crops.
