In pot trials with cauliflower, heavier liming of acid soddy-podzolic soils from 1/4 up to full hydrolytic acidity resulted in more intensive utilization by plants of extra N of the soil, and in higher utilization of fertilizer N (on the average by 20% of that applied as NH4NO3). Under the action of Mo the utilization of soil N and fertilizer N (on the average by 8% of that applied) by cauliflower also increased. Heavier liming and higher rate of Mo resulted in much lower losses of fertilizer N in the form of gas.
