As " food of grain ", chemical fertilisers account for 40-60% of global food production, and their importance is obvious. But even in a few countries, the rate of use of chemical fertilizers is only between 60% and 70%. The loss of chemical fertilizers caused by volatilization, loss or leaching will not only result in huge economic losses, but also severe environmental pollution. By contrast, organic fertilizer improves soil structure and cultivates soil fertility because of its rich organic matter，which can significantly improve the rate of use of chemical fertilizers and alleviate acidification and soil agglutination problems to some degree.The combination of organic and inorganic components can not only reduce costs and improve efficiency, but also reduce fertilizer loss and protect the soil and the environment.

Angel yeast utilizes yeast metabolites and inorganic elements based on the low temperature granulation process to develop Semi-Organic Fertilizer, which achieves perfect integration and effective complementation between organic and inorganic elements. The product is in granular form with a diameter of 1.2 ~ 2.2mm and is 100% water soluble. With the intensive and widespread development of agriculture and the scarcity of freshwater resources, the agricultural area of drip irrigation and sprinkler irrigation is also expanding. Fully water-soluble inorganic organic fertilizers enable the simultaneous application of organic and inorganic substances, irrigation and fertilization, which can also improve the rate of fertiliser use while saving agricultural water and reducing labour, which has obvious advantages.

Semi-Organic Fertilizer uses Meta-Yeast as organic material, containing over 20% organic material and over 15% fulvic acid. Fulvic acid is a kind of organic substance with low molecular weight and high activity. When fulvic acid is applied to soil, it will affect the properties of soil, promote the formation of more stable aggregate structure of soil, enhance soil ventilation and facilitate the growth of crops. Fulvic acid is a hydrophilic colloid with strong water absorption capacity that maximum water absorption can exceed 500%. The weight of water absorbed by the saturated atmosphere may be more than two times its own weight. As an organic colloid with positive and negative charges, fulvic acid can is capable of adsorbing anions and cations, this ability allows these nutrients to be preserved in the soil and not lost with water, improving the utilization of the fertilizer ，which is particularly significant in sandy soils. Fulvic acid contains carboxyl, phenolic hydroxyle and other functional groups, has a strong capacity for complexion, chelation and superficial adsorption, which can reduce ammonium nitrogen loss; Increase the distance phosphorus travels through the soil, inhibit the fixation of water soluble phosphorus in the soil, convert the inefficient phosphorus into effective phosphorus, and promote the absorption of phosphorus through the root system; Fulvic acid can absorb and store potassium ions, and improve the content of available potassium content, especially the efficiency of potassium fertiliser.

Semi-Organic Fertilizer has over 17% of available potassium. Potassium is a driver of crop growth. There are about 60 kinds of enzymes in organisms that require potassium ion catalysis. Enzymes that can be activated are synthetasis, oxidcanalase and transferase. They are involved in biochemical processes like sugar metabolism, protein metabolism and nucleic acid metabolism, thus playing a unique physiological role in plant growth and development. In production practice, for plants that harvest mainly carbs, such as potatoes, fiber, sugars, etc., after application of potassium fertiliser, not only the yield is increased, but also the quality is significantly improved. Oil is an ester synthesized by glycerol and fatty acids, whereas glycerol and fatty acids are processed from sugar. Potassium promotes sugar metabolism and oil formation as a consequence. Therefore, applying potassium fertilizers to oilseed plants such as peanuts, soybeans and rapeseed can increase oil.

Potassium is also the componnent that has the most impact on plant health, because potassium is involved in almost all biophysical and biochemical processes in plant growth and development. Adequate supply of potassium nutrient elements usually makes plants have strong resistance under stress conditions, and plays an important role in enhancing plant cold resistance, drought resistance, saline-alkali resistance, disease and pest resistance.

Angel Yeast is committed to the concept of using biotechnology to serve plantation users, building on yeast metabolites and derived resources, and combining with relevant knowledge from soil science, plant physiology and fertilizer science, will continue to develop high-quality yeast-derived plant nutrition products.
