Abstract

The effect of fertilizers on the balance of trace elements and the sustainability of agriculture in Germany was studied. It has been established that the balance of basic nutrients in the soil is maintained at a deficiency-free level due to the systematic and balanced use of mineral and organic fertilizers. However, the German Government is currently actively implementing policies aimed at reducing the use of traditional forms of organic and mineral fertilizers, introducing alternative ways to ensure soil fertility and crop yields. The aim of such a policy is to reduce the negative impact of agrochemicals on the environment and greenhouse gas emissions, in particular.
