What is meant by organic fertilizers?
Organic fertilizer, also known as biological fertilizer or organic fertilizer, is a kind of animal and plant residues, excreta, biological waste and other organic matter as raw materials, after processing made of fertilizer. It has a variety of remarkable characteristics and advantages, and is an indispensable part of modern agriculture. The following is a detailed analysis of organic fertilizers: Definition and source Definition: Organic fertilizer refers to organic matter derived from animal and plant residues, excreta, biological waste, etc., after certain treatment and processing, used to improve soil fertility and provide plant nutrients. Sources: Extensive and diverse, including but not limited to human and animal excrement, crop stalks, green manure plants, cake fertilizer (such as soybean cake, rapeseed cake and other pressed residue), peat and humic acid fertilizer, soil fertilizer (such as river mud, lake mud, etc.). 2. Characteristics and advantages Natural environmental protection: Organic fertilizer is derived from nature, does not contain chemical synthetic substances, and is harmless to the soil and the environment. Comprehensive nutrients: containing nitrogen, phosphorus, potassium, trace elements and other nutrient elements, can meet the overall needs of plant growth. Lasting fertilizer effect: decomposition in the soil is slow, can provide long-term nutrient supply, with lasting fertilizer effect. Improve soil structure: increase soil organic matter content, improve soil aggregate structure, and improve soil water and fertilizer retention ability. Promote microbial reproduction: increase the number and activity of beneficial microorganisms in the soil and promote soil biological cycling. Reduce environmental pollution: Compared with chemical fertilizers, the application of organic fertilizers can reduce soil and water pollution. Iii. Classification Organic fertilizers can generally be divided into the following categories: Manure manure: including human manure, livestock manure and poultry manure. Compost: compost is mainly composed of crop straw, mixed with a small amount of human and animal feces and urine, including compost and compost. Green manure: a general term for fresh green plants, such as sesbania, 苕子, mung beans, alfalfa, etc. Cake fertilizer: a variety of oily seeds after pressing oil residue, such as bean cake, rapeseed cake and so on. Peat and humic acid fertilizers: naturally occurring peat and humic acid. Soil fertilizer: including river mud, lake mud, ditch mud, wall soil, kang soil, etc. 4. Role and effect Improve soil fertility: increase soil organic matter content, improve soil structure, and improve soil water and fertilizer retention ability. Provide a full range of nutrition: to provide crops with nitrogen, phosphorus, potassium and other nutrients and trace elements. Enhance crop resistance: improve the resistance of crops to disease, drought and flood. Improve food safety and green: reduce the toxicity of heavy metal ions to crops, improve the safety and quality of agricultural products.
Organic fertilizers are materials derived from plant or animal matter that are used to enrich the soil with nutrients. They include compost, manure, bone meal, and green manure. Organic fertilizers improve soil structure, increase its ability to retain water and nutrients, and support a healthy soil ecosystem by promoting microbial activity. Unlike synthetic fertilizers, they release nutrients slowly and sustainably over time, reducing the risk of over-fertilization and environmental pollution.

These fertilizers are stable and can be easily transported at long distances. Natural fertilizers are insufficient for all the world.
How do fertilizers affect resources?
the affect of fertilizers on the resources is that our farmers use fertilizers in order to maintain the fertility of soil except organic fertilizers
What are 2 disadvantages of organic fertilizer?
