BGF product applications include solid and liquid.
Key components of solid products include:
Diversified (different structures and molecular weights) organic matter (〜 80%), basic nutrients nitrogen, phosphorus and potassium (5%), more than 30 kinds of medium and trace elements (including 17 elements constituting plants), and diversified microorganisms (more than 40 kinds of bacteria and more than 20 kinds of fungi).
Liquid products:
The components and functions are similar to solids, and the water-soluble components are significant.
The yield and quality of crops are determined by the soil fertility, which depends on the content of organic matter in the soil. Soil organic matter generally refers to the carbon containing organic compounds existing in various forms in soil, which is the basis of soil fertility and one of the important indicators to measure soil fertility. It can be said that there is no soil fertility without soil organic matter, and more than half of the soil organic matter is humic acid, which is the "reservoir" of plant nutrient elements and physiological active substances.
Carbon rich and multi carbon organic matter are the main characteristics of BGF products. Biological carbon is mainly a very stable macromolecular organic carbon structure with large molecular weight and poor solubility. It is invalid organic matter without deep processing. BGF technology solves the technical problems of stable structure of coal based materials and difficult biochemical utilization, mainly to stimulate the physical, chemical and biochemical activity of humic acid in lignite raw materials, so that it has applicability, effectiveness and safety.
There are nearly 60 different elements in plants. The prerequisite for healthy growth of crops is to take enough essential elements. BGF raw materials contain a variety of bacteria and fungi. Through the reaction process of BGF, lignite is degraded in multiple stages, organic carbon is activated, and the microbial population structure is adjusted. The microbial population adapted to the BGF product structure is enriched, so that large, medium and small molecular organic matter, medium and trace elements are distributed in multiple levels, so as to meet the nutritional needs of crops at different stages from seedling to harvest.
Microbes need inorganic elements to maintain normal growth and metabolism, and these elements need to be manually added to conventional fertilizers. The main raw materials of BGF, such as lignite, are enriched with a variety of mineral inorganic elements under the long and complex geological process of coal formation. The structure of raw coal is changed through the BGF reaction process, and these elements are released into BGF products, becoming biological and chemical available elements, which play an important role in plant cells, metabolic process, cell osmotic pressure and material transport.
No matter soil improver, plant nutrient, organic fertilizer, etc., some toxic and harmful elements should not exceed the standard, or they will do great harm to soil, environment, crops and human beings. Antibiotics, hormone residues and heavy metals are unavoidable for many "organic" products at present. According to the national standard Limit Requirements for Toxic and Harmful Substances in Fertilizers, toxic and harmful elements such as soil improvers, plant nutrients and organic fertilizers cannot exceed the standard. The following table shows the standard and "cleanliness" of BGF products on these elements.
