就降低用于土壤的化肥量和影响环境的因素而论,德国科学家们相信,在某一阶段农民们对作物使用化肥实际上可能是在浪费钱。由德国研究协会(DFG)所支持的研究巴经观察到氮是怎样影响油菜种子产量和品质的,并确信该研究结果可适用于其他许多作物。
To reduce the amount of chemical fertilizers used in the soil and the factors that affect the environment, German scientists believe that it may actually be a waste of money for farmers to use fertilizers for crops at some stage. Studies supported by the German Research Association (DFG) have observed how nitrogen affects the yield and quality of rapeseed seeds and is convinced that the results of this study are applicable to many other crops.
