Seaweed fertilizer is rich in organic matter and slow-release factors, and has a long effect, which can improve soil microecology, live soil to promote root and resist heavy stubble.
Seaweed fertilizer can directly increase the organic matter in soil or through plants, and activate all kinds of beneficial microorganisms in soil. These microorganisms can act as catalysts in the metabolic cycle of plants and microorganisms and increase the biological efficiency of soil. Plant and soil microbial metabolites can provide more nutrients for plants.
At the same time, the chelating system formed by the polysaccharides of sea algae can release the nutrients slowly and prolong the fertilizer effect. In addition, it contains natural compounds such as sodium alginate is a natural soil conditioner, can promote the formation of soil aggregate structure, improve the internal pore space of soil and coordinate the proportion of solid, liquid and gas in soil, the recovery loss due to soil burden and chemical pollution of the natural balance of glue, increase soil biological activity, promote the release of the available nutrient, is beneficial to root growth, increase crop resistance and the ability to resist continuous cropping.
