Why Do We Need Fertilizers To Cultivate Healthy Soils And High-yielding And Nutritious Crops?

- Jun 13, 2020-


Nutrients are removed from the field as the crop is harvested, which is called soil nutrient consumption. The amount of nutrients taken away during harvest is proportional to the yield, and the amount of nutrients removed from different crops and different parts of the same crop are different. In order to maintain soil fertility and achieve sustainable development of crop yield and quality, the nutrients removed from the field and the nutrients lost to the environment with the harvest must be supplemented by organic fertilizers and/or inorganic fertilizers.

In areas with poor soil fertility and economic benefits from fertilization, higher fertilization rates, combined with other necessary soil fertility management measures, are necessary to reduce nutrient limiting factors, increase the effectiveness of nutrients on crops, and improve soil health. of.

In order to achieve long-term middle to high yields to improve food security and farmers' income, it is not enough to rely solely on background nutrient inputs, such as soil nutrient supply, atmospheric subsidence, biological nitrogen fixation, and livestock manure return. To maintain high yields, farmers usually need to invest additional nutrients in the form of chemical fertilizers or other commercially available organic fertilizers. Insufficient nutrients can be supplemented by inorganic and/or organic fertilizer inputs. In the case of application of chemical fertilizers, they can be supplemented in the form of compound fertilizers or a mixture of multiple fertilizers.
