Description
The effect of both liquid ammonia and a solution consisting of ammonium nitrate and urea (30 % N) on forage plant yields and quality was found to be similar to that of ammonium nitrate, and these forms of nitrogen fertilizers are suitable for improving the productivity of grass pastures. Liquid ammonia differs from ammonium nitrate by its longer aftereffect so that it is possible to place the annual amount of nitrogen in one or two portions. Liquid ammonia produces a positive effect on the life activities of ammonifying, nitrifying, and nitrogen-fixing microorganisms. As compared to ammonium nitrate, the amounts of protein nitrogen and water-soluble carbohydrates in pasture forage were higher when the grass stands had been topdressed with a solution of ammonium nitrate and urea.
