acid modification: Best Effect, Safety and No Disadvantage

★ All Biological Acid Neutralizing Agent,Without Chemical Products

Main raw materials for oyster shell soil conditioner are marine cultivated oyster shells. After aging fermentation of oyster shells and a large number of algae end plankton, raw materials are  organics end processing process uses bio-engineering technology without any chemical products and so they are 100% biological organic products. The product is weak alkaline and the neutralization reaction is formed in the acidified soil to decrease soil acidification, dissolve add precipitation and improve soil.

★ Nanometer Calcium Carbonate is Small and has Strong Fertility Ability.

Oyster Shell is the product of biomineralization of macromolecular organic matter and its calcium carbonate or organic-inorganic compound containing calcium carbonate is active nano calcium carbonate and ordinary mineral calcium carbonate crystal is micron or millimeter level calcium carbonate. Nano calcium carbonate has small size effect, and is easy to be absorbed by the plant, thus having a huge surface area. It is not only attached with a large number of calcium ions and magnesium, zinc, iron and manganese but also can adsorb large amounts of nutrient ions in soil and improve soil nutrient retention capacity.

★ Cellular Structure to Increase Water Retention by 3 Times

Oyster shell calcium is 3 kind of micro poly porous structure arrangement, i.e., porous honeycomb structure, and has strong adsorption and its absorbent is 3 times more than conventional soil conditioner. It can be used as water retaining agent to retain water and fertilizer and prevent water and fertilizer from loss and has drought resistance.

★ No Troubles After Soil Improvement,Soil Conditioner Without Side Effect

Traditional acid modification method by using lime and calcined ore just renders short-term effect but causes long term troubles. Soil ecology is brought into vicious cycle, such as using lime for acid

modification will easily cause roots burning of crops an3 soil hardening. If using calcium nitrate and calcium superphosphate for acid modification, soil compaction is caused, which is one of the causes for soil acidification.

Oyster shell is composed of minerals and protein polysaccharide and minerals are mainly calcium and among others, magnesium, sodium and barium. After processing, it is weak alkali and has the best effect of acid modification, promotes the formation of soil aggregate structure, improves soil physical properties and soil microbial community formation and provides a favorable ecological environment for the growth of crops, so as to thoroughly solve soil acidification.

Calcium Supplement: Organic, Nutritious, Pollution Free

★ Organic Calcium: Good Absorption and Good Effect

Oyster calcium is different from inorganic calcium contained in mineral ores and it is organic calcium formed by all natural oyster metabolites. It has high activity and is easy to get absorbed by crops. It is not mineralized in soils and can be used for a long time. It can improve soil fertility and has no side effect to soil and crops. It helps supplement calcium in crops and prevents calcium deficiency and improves the appearance of crops with fruit tough- ness of high density, good taste and storage resistance.

★ Calcium content of 46%

Oyster shell soil conditioner has 46% of calcium content which is highly active organic calcium, and is easy to degrade and absorb and has long life time, and is not fixed so it is safe and efficient to soils.

★Active Calcium

Oyster active calcium powder belongs to all natural semi soluble active calcium and can effectively solve the problem of soil acidification and compaction caused by a large number of chemical fertilizers, activate and modify the nutrients required by plants and improve utilization rate of fertilizers. Active calcium can effectively solve the problems caused by calcium deficiency such as bitter pit disease, spots disease, umbilical rot, anthracnose of fruits, vegetables and other crops, as well as difficulty in peanut fruit bearing and fruits being not full.

★ More Than Just Calcium

In addition to calcium, oyster shell soil conditioner is also rich in other active substances such as zinc, silicon, magnesium, boron, chitin, chitosan, protein, seaweed, amino oligosaccharides and bismuth titanium and other rare earth elements.
