Calcium oxide ≥ 23%
Magnesium oxide ≥ 7%
Silicon dioxide ≥ 20%
Product Introduction
1. Calcium supplementation - Calcined calcium is made by calcining oyster shells. Oyster calcium is a marine active calcium fertilizer that is rich in natural organic matter and various trace elements. It is nutritionally comprehensive and oyster calcium is warm alkaline calcium.
2. Water and fertilizer retention - The unique microporous structure has strong water storage capacity, obvious capillary action, and a natural multi-dimensional surface structure, making it an ideal adsorption carrier for ions. It can provide slow-release effects on fertilizer nutrients, retain water and fertilizer, improve soil particle structure, reduce soil compaction, and increase fertilizer utilization efficiency.
3. Adjusting acidity and reducing salinity can effectively improve acidic soil by gently and persistently adjusting acidity, reducing soil salt damage, and adapting to crop growth.
4. Reducing heavy metals can effectively adsorb and passivate heavy metals, reducing crop absorption of heavy metals.
5. Improving quality and resistance to diseases, it contains abundant organic compounds such as chitin and amino acids, effectively preventing various rot diseases, fruit cracking, rough skin disease, apple bitterness and spot disease, pear iron head disease, black heart disease, peach soft rot disease, tomato and pepper navel rot disease, rice root rot disease, etc.
6. Calcium is a quality element that significantly improves the appearance, hardness, and storage properties of crop fruits. It also has the effect of improving taste and sweetness.
Technical indicators
Calcium oxide ≥ 23% Magnesium oxide ≥ 7% Silicon dioxide ≥ 20%
Usage method
Bottom fertilizer application, burial application, fruit tree 0.5-1kg/plant, field crop base fertilizer 20-40kg/mu, root and stem crop base fertilizer 40-60kg/mu, vegetable base fertilizer 40-60kg/mu, mixed with organic fertilizer for better results
Matters needing attention
The amount of alkali added varies depending on the soil conditions and fertilizer usage habits.
