Little information is presently available on the effects of N source on dryland crop production in the Northern Plains. Therefore a field experiment was conducted for 4 years to assess the relative merits of ammonium sulfate, ammonium nitrate, calcium nitrate, and urea applied annually at 55 and 110 kg N/ha to both corn (Zea mays, L.) and bromegrass (Bromus inermis, L.) grown on a fine sandy loam (pachic haploboroll) with surface pH of 6.5 and no free carbonates. Plants were harvested at… CONTINUE READING
