Mix represents solution of ammonium nitrate (NH4NO3) and carbamide ((NH2)2CO) in water, in a proportion 1:1. The KAC 32 fertilizer does not contain water ammonia that gives certain advantages before similar solid nitrogen fertilizers in use.
Karbamidno ammoniac mix KAS is made in the following branded execution:
In these fertilizers the content of nitrogen makes 28%, 30%, and 32% respectively. It should be noted that the last mix — KAS-32, crystallizes at 0 °C while KAS-30 – at -9 °C, and KAS-28 only at -17 °C. Therefore we advise in cold weather to use the KAC 28 fertilizer.
KAS-32 contains the following forms of nitrogen: ammoniyny, amide and nitrate forms thanks to what fertilizer works it is prolonged (that is it is long), and plants are provided at the same time with three forms of nitrogen throughout growth and vegetation.
Physics – chemical indicators of KAC 32

|Density, kg/cm3, at 20o||1306 — 1337|
|Temperature of crystallization, ° C||- 2|
KAC 32 conforms to all requirements
A half of composition of mix is the share of an amide form of nitrogen (50%), a quarter — on ammoniac (25%), and a quarter — on nitric (25%).
All forms of the KAC 32 fertilizers not of a letucha, and also do not attract nitrogen loss. Thereof they can be introduced superficially without turning in soil. Nitrate and ammoniac forms — are directly very available to plants. First of all the nitrate nitrogen which is very mobile in the soil is acquired. It is necessary to tell that ammoniac nitrogen is already late in the soil and does not disappear in deeper layers of the earth. When entering KAC 32 into the soil, this form karbamidno of ammoniac mix collects in an arable layer, and also becomes available throughout vegetation of plants. Then the part of the KAC 32 ammoniac form turns into nitrate. The amide form in the soil will be transformed in ammoniac, and over time to nitrate. The similar system of digestion of nitrogen does karbamidno ammoniac mix — fertilizer of at the same time direct and long action.
KAC 32 is widely applied:
- for radical top dressing of plants,
- for the main introduction under plowing and cultivation before crops,
- for introduction on a soil surface before sowing or after it.
