abstract:
The invention relates to a bio-organic fertilizer with high calcium in bone meal and a preparation method thereof, which is prepared by mixing 1-3 parts of bone meal, 10-25 parts of farm manure, 18-27 parts of active calcium, 1-5 parts of trace element compounds and 20-30 parts of humic acid.
Grain; Granulating 0.5- 1 serving of biological bacteria; Mixing the above granules, adding 10-20 parts of nitrogen fertilizer, 5- 14 parts of phosphorus fertilizer and 3-8 parts of potassium fertilizer, and uniformly mixing to obtain the biological preparation with high calcium in bone meal.
Machine fertilizer. The bone meal high-calcium bio-organic fertilize of that invention has comprehensive nutrition, scientific and reasonable proportion, and can meet the requirements of crop for various nutrients in the whole growth period. Especially bone meal, which is rich in organic calcium and trace elements, is a farming practice.
Animals like organic fertilizers that are easily absorbed. At the same time, the active calcium oxide in the product can effectively degrade soil acid damage, improve soil ecological environment and increase soil PH value. Calcium ions can promote the transformation and absorption of phosphorus and potassium.
Use. The soil became loose, which solved the problem of soil hardening.
