The danger of excessive chemical and organic fertilizer used.

1. Lead to deterioration of soil properties
In the field a large number of single element or chemical fertilizer application, crop nutrient can not be absorbed and used effectively. The over nutrient like  nitrogen, phosphorus, potassium and others will cause soil consolidation because various of formation nutrient salts accumulate in the soil, causing structural imbalance of soil nutrients, deterioration of physical properties will take part and harmful metals and harmful bacteria exceeded, resulting in deterioration of soil properties.

2. Result in decreased of fruits quality.
Partial applied a chemical fertilizer, resulting in crop nutrition disorders. Some of the physical transformations take place in vivo synthesis blocked, resulting in lower product quality, such as effected the tasty of the fruits, vegetables and when we eaten them, feel without fragrance, and perishable and can not be kept longer time. The reason is excessive application of chemical fertilizer.

3. Cause environmental pollution
Because too much organic fertilizer was applied to the soil, water-soluble nutrients and other substances and agricultural irrigation water leaching into the groundwater and rivers, causing some of the ground water and river pollution, until to the groundwater, rivers, lakes were eutrophication, groundwater does not lead to drink. Death rivers and death lakes often occurs within the phenomenon of fish and shrimp.

4. Reducing of production and effected farmer’s income
First cultivated by the farm level, crop nutrient requirement constraints and other factors, crop production can not be very high; the second is due to too much uniformity in the application of fertilizers, resulting in nutritional imbalances. The nutrient imbalance not only increase costs but also effected productions, and caused the low quality of agricultural products. Affected the selling price and so on, bringing big losses to farmers.
