Organic fertilizers are fertilizers that can be decomposed to release nutrients, improve soil, promote microecological balance, and increase soil fertility. Organic fertilizers can be natural materials such as animal manure and plant straw, or they can be composite materials that have been composted and fermented. Unlike chemical fertilizers, organic fertilizers are released slowly, which is beneficial to improving soil water holding capacity and maintaining the balance of nutrients such as nitrogen and phosphorus.
- Types of organic fertilizers
a. Animal manure: pig manure, cow manure, chicken manure, etc.
b. Plant straw: rice straw, wheat straw, bean straw, etc.
c. Composting: mixing animal and plant residues together for fermentation and composting.
d. Green manure: mainly refers to leguminous crops used for intercropping, such as soybeans and broad beans.
e. Biofertilizer: fertilizer made by fermenting animal and plant manure using high-efficiency bacteria.
f. Liquid organic fertilizer: liquid fertilizer extracted from plant residues using microbial treatment technology.
- Application of organic fertilizers
Organic fertilizers are widely used in agricultural production and can effectively improve the yield and quality of crops. Different crops require different organic fertilizers. The specific application methods are as follows:
a. Food crops: green manure and compost can improve the yield and quality of crops.
b. Fruits and vegetables: liquid organic fertilizers and biofertilizers can improve the quality and taste of fruits and vegetables.
c. Tea: green manure and biofertilizers can improve the aroma and nutrient content of tea.
In summary, organic fertilizers, as an important part of sustainable agriculture, can improve soil fertility, protect the environment and improve the quality of agricultural products. Choosing organic fertilizers suitable for your crops can not only reduce input costs, but also improve the yield and quality of crops.
