What materials can be processed and produced into bio organic fertilizers? What raw materials can be used as the main ingredients for bio organic fertilizers?

Organic fertilizers can be specifically divided into the following categories:

1、 Product organic fertilizer:

1. Industrial waste: such as distillers grains, vinegar residue, cassava residue, sugar residue, furfural residue, etc;

2. Urban sludge: such as river silt, sewer silt, etc. A comprehensive classification of organic fertilizer raw material production and supply bases: silkworm excrement, mushroom residue, kelp residue, phosphate citric acid residue, cassava residue, protein paste, sugar aldehyde residue, amino acid humic acid, oil residue, plant ash, shell powder, etc., as well as peanut shell powder.

2、 Bio organic fertilizer:

1. Agricultural waste: such as straw, soybean meal, cotton meal, etc.

2. Chicken manure dewatering machine for livestock and poultry manure, such as chicken manure, cow, sheep, and horse manure, and rabbit mobile conveyor manure;

3. Household waste: such as kitchen waste, etc

How to distinguish the quality of organic fertilizers

tells you how to distinguish the quality of organic fertilizers. There are multiple methods to distinguish the quality of organic fertilizers:

1. The soaking method involves taking a water cup, soaking the organic fertilizer sample in water, and then crushing the organic fertilizer soaked in water by hand. Stirring it can visually reveal the raw materials of the organic fertilizer; If the organic fertilizer and water are separated in a short period of time, it indicates that the organic fertilizer ratio is high and contains more soil.

2. Smelling method: Carefully smell the fat to see if there is an ammonia smell, fecal smell, or sludge smell. Good organic fertilizer should have a thoroughly decomposed smell.

3. Using the hand twisting method, take organic fertilizer and press it back and forth with your thumb and index finger. If it feels uncomfortable, there may be sand or other impurities inside.

4. Strain testing method: Take a water cup and put the organic fertilizer inside, sprinkle a little water (be careful not to soak in water, just keep it moist), and place it in a warm and suitable place. Good organic fertilizer will carry white mycelium, and when you break open the organic fertilizer particles, you will also see white mycelium inside.

5. Potting test method: Take a pot of flowers, grab a large handful of organic fertilizer granulator and sprinkle it directly on the root and stem of the flower. Water it with water. Good organic fertilizer will gradually grow white mycelium, promoting plant growth. Poor quality organic fertilizer will smoke the seedlings, causing the plant to gradually wilt until death.

6. Comparative experiment method: After selecting organic fertilizer, leave a portion of it unused when planting crops, and observe the performance of the plants. Good organic fertilizer will have significant effects on growth, yield, and quality.

7. Check if the packaging meets the specifications and if it is authorized for production (usually authorized manufacturers do not have their own factories or sources of raw materials)

8. Try not to purchase packaging in foreign languages, as organic fertilizers are all waste and reused, and it is almost impossible to import them from abroad.
