AMMONIA-DEPOT FERTILIZATION OF STRAWBERRIES |
| Authors: | U. Kreusel, F. Lenz |
| Abstract:
Soluble nitrate fertilizers like calcium ammonium nitrate often caused nitrate leaching in cultivation of strawberries. A field experiment was conducted in 1993–1995 to compare the conventional application of calcium ammonium nitrate over the whole area with a ammonia-depot fertilization. There were no effects of fertilization on flowering, on final fruit yield, that is number and weight of strawberry fruits and on the mineral composition of strawberry plants and fruits. Soil analysis from four weeks after fertilization until the end of September showed the reduction of nitrate in the soil with ammonia-depot fertilization. | |
