The correct method of fertilizing oilseed oil

Oil cake, also known as rapeseed cake and rapeseed meal, is a by-product of rapeseed oil extraction. Oil cake can be used as fertilizer , but it needs to be processed in a certain way. Here we will talk about the correct way to apply oil cake.

1. The correct method of fertilizing oilseed

1. Direct application: Crush the oil cake and apply it directly to the soil. It can be used as base fertilizer or topdressing. The application amount depends on factors such as crop type, growth stage, soil fertility, etc., and generally 200-300 kg per mu.

2. Composting: Mix oil cake with other organic waste (such as livestock and poultry manure, straw, etc.), pile them up and ferment them to make organic fertilizer . The composting time is generally 2-3 months. During the composting process, attention should be paid to ventilation, moisture retention and rain protection.

3. Fertilizer making: Mix oil cake with water, ferment it and make it into decomposed organic fertilizer. The composting time is generally 1-2 months. During the composting process, attention should be paid to ventilation, moisture retention and rain protection.

4. Prepare compound fertilizer: Mix oil cake with other fertilizers (such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, etc.) to make compound fertilizer. The application amount and method depend on factors such as crop type, growth stage, and soil fertility.

2. How to use farmyard manure correctly?

1. Compost: Fertilizer made from accumulated weeds and garbage. It can be used according to local conditions and is best used as base fertilizer in combination with spring and autumn plowing.

2. Green manure: It is best used as base fertilizer or topdressing for leguminous crops, using the nitrogen-fixing effect of rhizobia to improve soil fertility.

3. Sheep manure: It is a thermal fertilizer and should be mixed with pig manure. It is suitable for cool soil and shady slopes.

, Pig manure: It contains a lot of organic matter and nitrogen, phosphorus and potassium. The decomposed pig manure can be applied to various soils, especially hot and humid soils with good drainage.

5. Horse manure: It has high content of organic matter, nitrogen and cellulose, contains high-temperature fiber-decomposing bacteria, ferments quickly in the pile, has high heat, and is suitable for moist and heavy soils, shady slopes, and severely compacted soils.

6. Cow dung: It has a low nutrient content and is a typical cool fertilizer. Dry the cow dung and add 3-5% wood ash, phosphate rock powder or horse dung for stacking. This can accelerate the decomposition of the cow dung and improve the fertilizer efficiency. It is best used in combination with hot fertilizers, or applied to sandy loam and sunny slopes.

7. Human feces and urine: They can be used directly after fermentation or mixed with soil to make manure soil as topdressing.

8. Poultry manure: It has high nutrient content and can be used as seed fertilizer and top dressing fertilizer. It is most suitable for vegetables .
