Abstract
In field experiments in 1956-1962 on heavy loamy derno-podzolic soil and on sandy loamy soil under potatoes, oats, spring wheat and maize, anhydrous NH3 and NH4OH were as effective as NH4NO3. Systematic application of the liquid fertilizers increased soil acidity to the same extent as did NH4NO3 and did not increase the solubility of the soil humus.
