Product Features
Organic fertilizers are mainly divided into the following categories:
Farmyard manure
1.Compost: Made from various types of straw, fallen leaves, weeds, human and animal feces, etc., piled up and fermented.
2.Waterlogged compost: Similar to compost, but fermented under flooded conditions.
3.barnyard manure: Made from livestock and poultry feces mixed with bedding, etc.
4.Green manure: Part or all of the green plant body is pressed into the soil as fertilizer, such as alfalfa, astragalus, etc.
5.Cake fertilizer: Such as rapeseed cake, cottonseed cake, bean cake, etc., which are the residues left after oil is pressed from oilseed crop seeds.
Commercial organic fertilizer
1.Refined organic fertilizer: Made from animal and plant residues, etc., through fermentation, deodorization, drying, crushing and other processes, with relatively high nutrient content and less impurities.
2.Bio-organic fertilizer: In addition to containing organic matter, beneficial microorganisms such as Bacillus subtilis and Bacillus licheniformis are also added, which can improve the soil microbial environment and increase soil activity.
Organic-inorganic compound fertilizer
Mix organic fertilizer and inorganic fertilizer in a certain proportion, which has the advantages of both organic fertilizer and chemical fertilizer. It can provide long-term nutrients and quickly meet the needs of crop growth.
Packing
Application
Usage method
1.Base fertilizer: Before planting, spread organic fertilizer evenly on the soil surface, and then deep plow the soil to make the organic fertilizer and soil fully mixed.
2.Topdressing: During the growth period of crops, apply organic fertilizer around the root system of crops according to the growth conditions and fertilizer requirements of crops. It can be applied in furrows or holes, and the soil should be covered and watered in time after application.
3.Foliar spraying: After fermentation, filtration and other treatments, the organic fertilizer is diluted into a solution of a certain concentration and sprayed evenly on the leaves of crops with a sprayer. This method is mainly used to supplement the nutrient needs of crops in the later stage of growth.
Tips
1.Fully decomposed: Undecomposed organic fertilizer will ferment in the soil to generate heat, burn the root system of crops, and may also carry pathogens and eggs, causing diseases and insect pests.
2.Avoid mixing with alkaline fertilizers: organic acids in organic fertilizers will react with alkaline substances in alkaline fertilizers, reducing fertilizer efficiency.
3.Control the amount of application: excessive application of organic fertilizers may lead to soil nutrient imbalance, affect crop growth, and cause resource waste and environmental pollution.
4.Pay attention to the time of fertilization: generally fertilize in the morning or evening, avoid fertilizing at high temperatures at noon to avoid fertilizer volatilization loss or damage to crops.
5.Use with chemical fertilizers: organic fertilizers have comprehensive nutrients but low content, while chemical fertilizers have high nutrient content but single types. The combination of the two can complement each other and improve fertilizer utilization.
