Organic active calcium fertilizer is a new type of calcium supplement and soil conditioner.

It is produced from the Marine shells and seaweed extracts .
After several special process like fermentation, calcination, activation,grinding,Matrine shells become a very high active fertilizer which contains high nature organic calcium(2-3 times than traditional calcium fertilizer) and other trace-elements like Mg,Si,Zn,B..etc.Seaweed extract contains cytokinin,betaine,mannitol,microelements, organic iodine..etc

It is suitable for most kinds of crops which need large amount of calcium supplement like groundnuts,strawberry,grapes, cotton, tomato, eggplant, most leafy vegetables and fruit trees. It is very suitable for acidic soils and can also reduce the pH of alkaline soils

Specification:
Appearance: Granule
Particle Size: 2-3mm
Color: Off white to greenish
Main component: CaO≥42%,Seawwed≥8%,Trace elements≥3%
PH: 7.5-10.0

Function & Feature:
1. High content of active calcium.
Contains 43% natural organic active calcium, which is derived from shell of natural sea creature. Its high activity, easy to be absorbed by crops; quick-effect calcium with slow-acting calcium to make continuous calcium supply in the whole life cycle of plant.
2. Rich Nutrients. Multiple medium and trace elements such as silicon, magnesium, zinc and boron, as well as active substances such as chitin, amino acids, proteins and oligosaccharides.
3. Enriched with rooting factor, the crop continuously produces new roots, and maintains strong calcium absorption ability for life.
4. Adjust Soil pH. PH of acidic soil and alkaline soil tends to be neutral after application.
5. Excellent water retention capacity. The product has uniform particles, large specific surface area and strong water storage capacity.
6. High fertilizer retention capacity. The natural multi-dimensional structure surface is an ideal carrier for NH4+, PO4 etc and make nutrients releasing slowly.
7. Honeycomb microporous structure to improve air permeability
8. Strong resistance to nematodes This product contains chitin, which can effectively induce the growth of anti-nematode microorganisms and inhibit nematodes.
9. Increasing soil organic matter,improving soil structure. Enhancing abilities of preserving moisture and fertility.Improve nutrient environment for crops,and the effectiveness of fertilizer.

Direction for use:
1. Fruit tree:
Basal application or Topdressing application.
Radial furrow fertilization, dosage vary as the calcium deficiency; 2-6kg/plant
2. Vegetables:
Basal application should be ditched OR turn the soil 10-30 cm after broadcast application;
Topdressing application to be carried out at a distance of 3-10 cm from plant..150-300kg/acre.
3. Field crops:
Basal application should be ditched OR turn the soil 10-30 cm after broadcast application; 150-300kg/acre.

NOTES:
1. The product is not totally soluble bio-active calcium fertilizer, material can be mixed with water when topdressing; Remarkable efficacy used with other fertilizer together.
2. Adjust the dosage according to soil acidity, compaction, and calcium deficiency condition.
