Mineral N

Available soil mineral nitrogen (N) was determined in a Darling Downs clay at intervals of 4-6 weeks throughout summer and autumn after harvest of two cereals (wheat and oats), two oilseeds (rapeseed and linseed), and four grain legumes (chickpea, fieldpea, lupin and lathyrus). Soil mineral N (0-1.2 m) at 40,68, 107, 150 and 185 days after harvest was affected (P < 0.05) by the prior crop. At 40 days it was generally higher following grain legumes (34-76 kg/ha N) than following oilseeds or cereals (16-30 kg/ha N). Net increase during the next 145 days was in the order of cereals (2 1-27 kg/ha N) < oilseeds (40 kg/ha N) <grain legumes (53-85 kg/ha N). These differences are partly accounted for by differences in the quantities of N removed in the grain of these crops. However, a large quantity of mineral N accumulated following lupin even though a large quantity (80 kg/ha) was removed in the grain.

Solonetz Soil

Fluctuations of mineral nitrogen were studied for three years in two solodized solonetz soils at Narrabri, New South Wales, under a wheat summer-fallow management system. Changes in mineral nitrogen were related to plant uptake, soil environment characteristics (water, temperature and oxygen), and climate. NO3-N was the major form of soil mineral nitrogen, generally exceeding NH4-N with NO2-N occurring only occasionally (<1 �g N g-1). NO3-N accumulated during fallow to 67-111 kg N ha-1 in the profile just after sowing. Crop growth depleted NO3-N to 0-11 kg N ha-1 at flowering. Several significant falls in soil NO3-N (11-27 kg N ha-1) could not be accounted for by plant uptake, and were apparently caused by denitrification. Decreases due to leaching (including lateral leaching) were not detected. Redistribution of NO3-N down the profile was observed, the efficiency of leaching increasing with increased intensity of rainfall. NH4-N generally amounted to less than 25 kg N ha-1. Fluctuations in NH4-N which occurred within the profile, could not be related to observed factors and are unexplained. The effect of a drought year, 1965, was to inhibit mineral nitrogen accumulation, lessen the depth of leaching of NO3-N and depress plant uptake of nitrogen.
