Nine Common Problem of Soil (Part 1)

Soil is the basis of plants, it provide necessary nutrients and water for plants. If get problem with soil, it will directly influence the growth of plants, as well as the quality of fruits and yield output.

1. Imbalance of nutrients

In field daily management, farmers do not fertilize proportionally, and often focus too much on nitrogen fertilizer and phosphorus fertilizer, but ignore the importance of trace elements. It has contributed to the lack of trace elements and imbalance of nitrogen, phosphorus and potassium.

2. Soil pollution in farmland

Residual pollution from excessive use of chemical fertilizer, pesticides and untreated human waste, it will enter or remain in soil for a long time, once it exceed the self-purification capacity of soil, it will directly damage the soil. It will firstly destroy the soil ecological balance, a large number of beneficial organisms and microorganisms dying, soil biological populations decreasing, soil activity and survival rate declining, it results in the lose of production capacity and agriculture value.

3. Soil acidification

Soil acidification is mainly due to the excessive use of chemical nitrogen fertilizers and physiological acid fertilizers, which leads to the increase of acidic substances in the soil and acidification of the soil. Soil acidification will cause soil nutrient loss, activation of harmful heavy metals in soil, increase of harmful soil microorganisms, especially parasitic fungi, and accelerate soil barrenness and soil-borne diseases.
