Traditional and modern fertilization techniques and methods

Firstly, traditional fertilization methods include spreading fertilization, furrow fertilization and hole fertilization, including soil-based fertilizer, soil topdressing and foliar fertilizer in terms of fertilization time and use; Modern fertilization techniques include soil testing, formula fertilization, flushing fertilization and variable control fertilization, and attention should also be paid to base fertilizer, topdressing and foliar fertilizer from the fertilization time.

2. Comparison:

1, the traditional fertilization method has low fertilizer utilization rate, especially the leaching and volatilization of nitrogen, which leads to extremely low nitrogen utilization rate, serious waste and environmental pollution. As a base fertilizer, a large amount of phosphate fertilizer greatly increases the probability of phosphate fertilizer being fixed by soil, resulting in a decline in the utilization rate of phosphate fertilizer, and potassium fertilizer is less affected than the first two.

2. Modern fertilization technology is the diagnosis of soil and crops at present. In the early sowing stage or different growth stages of crops, we can judge the nutrient abundance of soil and crops, apply whatever fertilizer is lacking, and accurately control the amount of fertilizer applied, which not only improves the utilization rate of various fertilizers, but also saves the cost of purchasing fertilizers and protects the environment.
