Biochar-based Fertilizer Development

Unsuitable fertilizer varieties and unreasonable application methods are common in agricultural production, which not only lead to difficulties in improving crop yield and quality but also cause low fertilizer utilization, increased production costs, and environmental pollution. The application of biochar-based fertilizers developed by Lifeasible is not only beneficial to the improvement of agricultural quality and efficiency but also conducive to the control of agricultural surface pollution and the realization of the goal of carbon sequestration and emission reduction in agricultural soils.

We can use biochar prepared from agricultural and forestry waste as a biomass source. Our development direction includes charcoal-based nitrogen fertilizer, charcoal-based compound fertilizer, charcoal-based organic fertilizer, and charcoal-based compound fertilizer. Available applications involve field crops such as wheat, rice, corn, peanut, potato, cotton, etc., and facility vegetables such as chard, celery, green pepper, tomato, etc.

• Biochar raw material selection. Wheat straw, corn straw, peanut shell, cotton straw, pig manure, bamboo, rice husk, etc.
• Charcoal fertilizer ratio selection. We generally use a charcoal fertilizer ratio of 1:4 to 1:0.67, and different charcoal fertilizer ratios can indirectly influence the crop yield increase by affecting the slow-release effect of biochar on nutrients and the total nutrient content of charcoal-based fertilizer. It also directly affects the transportation and storage of the fertilizer by affecting the forming effect of the charcoal-based fertilizer.
• Preparation methods. We offer blending, adsorption, chemical reaction, coating, and blended granulation methods. The actual preparation process usually uses a combination of methods to achieve better slow release, molding, and other functional effects.
• Preparation process modification. In addition to the two basic raw materials of biomass charcoal and fertilizer, other substances are often added to optimize the slow-release performance or other functional effects of the charcoal-based fertilizer as needed. This can be achieved by adding modifiers to the char-based fertilizer preparation process or by modifying the biochar and then compounding the fertilizer nutrients.

Modifiers we offer and their effects

• The crop straw modifier prepared from oleic acid rare earth can increase the pore size and improve the structural stability of biochar made from crop straw.
• The soybean meal can promote plant growth and development.
• Bentonite, kaolin, and iron ore slag can slow down the release rate of nutrients and improve the soil.
• Humic acid activates soil enzymes, slows nutrient release, and complexes with heavy metals to reduce their biological effectiveness.
• An acidic wood vinegar solution can improve saline soils and inhibit pest and weed growth.
• Microbial agents can improve crop growth rate, survival, and tolerance by promoting enzyme activity and microbial activity.
• Urease inhibitors and nitrification inhibitors can slow down fertilizer loss.
• Organic pollutant-degrading strains can degrade organic pollutants such as polycyclic aromatic hydrocarbons.
• Aerobic fermentation of organic waste fertilizers can add active microorganisms and reduce the number of inorganic fertilizers added thus reducing costs.

Advantages

• Increases soil organic carbon and cultivates fertile soil.
• Increases soil porosity, improves soil slumping, and enhances root respiration.
• Enhance soil fertilizer retention performance, improve fertilizer utilization efficiency, and reduce chemical fertilizer use.
• Improving soil field water holding capacity, enhancing crop resistance to flooding and drought.
• Improves soil microbiological environment and reduces agricultural production diseases.
• Absorb and solidify toxic substances to ensure the safety of agricultural products for consumption.
