Biomass organic fertilizer: Sheep manure fertilizer
Basic components: Sheep manure contains rich organic matter, with the content generally above 25%. It can significantly improve the soil structure and increase soil fertility. It contains a large amount of major elements such as nitrogen, phosphorus, and potassium. Among them, the nitrogen content is approximately 0.7%-0.8%, the phosphorus content is about 0.45%-0.6%, and the potassium content is 0.4%-0.5%. It also contains medium elements such as calcium, magnesium, and sulfur, as well as trace elements such as iron, manganese, zinc, and boron, which can provide comprehensive nutrients for crops. In addition, sheep manure is rich in humic acid, with the content reaching 16%-20%. It can promote the formation of soil aggregate structure and enhance the soil's water and nutrient retention capacity.
More Details
Advantages:
- Long-lasting fertilizer effect: Nutrients are released slowly and continuously, meeting the needs of crops at different growth stages. l
- Soil improvement: It can regulate the soil pH value, enhance the activity of soil microorganisms, promote the reproduction and activities of beneficial microorganisms in the soil, and inhibit the growth of harmful microorganisms. l
- Improvement of crop quality: It can enhance the stress resistance of crops, reduce the occurrence of diseases and pests, decrease the amount of pesticides used, increase the vitamin content in vegetables, and enhance the nutritional value of crops.
- Environmental protection and sustainability: It reduces environmental pollution and meets the requirements of sustainable development.
Disadvantages:
- Harm caused by insufficient fermentation: If sheep manure is not fully decomposed and fermented, after being applied to the soil, it will continue to ferment and generate a large amount of heat, resulting in the phenomenon of root and seedling burning, which will affect the growth of crops.
- Potential to carry pathogens, eggs of insects: Sheep manure may contain some pathogenic bacteria, parasite eggs, weed seeds, etc. If it is not treated by high-temperature decomposition, these harmful organisms will enter the soil along with the application of the fertilizer, increasing the risk of the occurrence of diseases and pests and the growth of weeds.
Application scope:
Sheep manure fertilizer is suitable for various agricultural crops and cash crops, such as vegetables, fruits, flowers, grain crops, etc. Whether it is open-field cultivation or protected cultivation, good results can be achieved. It is especially suitable for cash crops with relatively high economic value such as fruit trees and vegetables, which can significantly improve the quality and yield of fruits.
Application method:
- Base fertilizer: Evenly spread the sheep manure fertilizer on the soil surface before planting, and then plow it into the soil to fully mix the fertilizer with the soil. Generally, the application rate is 2,000-3,000 kilograms per mu.
- Topdressing: Methods such as strip application, hole application or circular application can be adopted. Apply the sheep manure fertilizer near the roots of the crops, and then cover it with soil and water it. The amount of topdressing can be appropriately adjusted according to the growth situation of the crops and the soil fertility.
When using sheep manure fertilizer, it is necessary to ensure that it is fully decomposed, and apply it reasonably according to the needs of the crops and the soil conditions to achieve the best fertilization effect.
