Kiss, S., Simihăian, M.: Improving Efficiency of Urea Fertilizers by Inhibition of Soil Urease Activity

Abstract

1. Inorganic compounds tested for evaluation of their inhibiting effect on soil urease activity, urea hydrolysis, ammonia volatilization and nitrous oxide emission -- 2. Organic compounds tested for evaluation of their inhibiting effect on soil urease activity, urea hydrolysis, ammonia volatilization, and nitrous oxide emission -- 3. Combined use of inhibitors of soil urease activity -- 4. Comparative studies on the efficiency of different inhibitors on soil urease activity -- 5. Compounds tested for evaluation of their inhibiting effect on both soil urease activity and nitrification -- 6. Soil urease inhibitors used in combination with nitrification and/or algal inhibitors -- 7. Effect of soil urease inhibitors on germination, growth, and yield of plants.
