Diammonium phosphate is a high-concentration, quick-acting
fertilizer that can be applied to a variety of crops and soils.
It can be applied in autumn for tilling and in spring during
sowing, as well as for pre-sowing cultivation. Dissolving in
soil, it provides temporary alkalization of pH of the soil
solution around the fertilizer granule, thus stimulating better
uptake of phosphorus from the fertilizers on acid soils.
