What is the difference between organic fertilizer and chemical fertilizer? Please explain in detailThere are 7 differences between organic fertilizer and chemical fertilizer, described in detail below for reference:
1. Organic fertilizer contains a large amount of organic matter and has a clear effect on improving soil and building fertility; chemical fertilizer can only provide inorganic nutrients to crops, and long-term application will have adverse effects on the soil, making the soil "more and more demanding the more it is cropped."
2. Organic fertilizer contains multiple nutrients, and the nutrients it contains are comprehensive and balanced; while chemical fertilizer contains only a single type of nutrient, and long-term application easily causes nutrient imbalance in soil and food.
3. Organic fertilizer has a low nutrient content and needs to be applied in large amounts, while chemical fertilizer has a high nutrient content and is applied in small amounts.
4. Organic fertilizer has a long-lasting fertilizing effect; chemical fertilizer has a short and fierce fertilizing period, easily causing nutrient loss and environmental pollution.
5. Organic fertilizer comes from nature, contains no chemically synthesized substances, and long-term application can improve the quality of agricultural products; chemical fertilizer is a purely chemically synthesized substance, and improper application can reduce the quality of agricultural products.
6. In the production and processing of organic fertilizer, as long as it has undergone sufficient decomposition treatment, application can improve the drought resistance, disease resistance, and insect resistance of crops and reduce the amount of pesticides used; long-term application of chemical fertilizer, because it lowers plant immunity, often requires large amounts of chemical pesticides to maintain crop growth, easily causing an increase in harmful substances in food.
7. Organic fertilizer contains a large amount of beneficial microorganisms, which can promote the biological transformation process in the soil and help continuously improve soil fertility; long-term large-scale application of chemical fertilizer can inhibit the activity of soil microorganisms, leading to a decline in the soil's self-regulating ability.
