Sprayed microbial culture coating speeds organic fertilizer fermentation while improving storage stability, odor control, and crop productivity.

A high-C/N exogenous carbon mixture promotes microbial nitrate assimilation while reducing nitrogen fertilizer use and N2O emissions.

This composting method separates liquid and solids, agitates sludge, and uses sloped open-air channels to reach 65–70% moisture.

A rotary drum acidifies and ammoniates poultry litter, raising nitrogen content while drying the product and reducing pathogens and odors.

This process separates and hygienizes fiber solids to produce a low-salt peat substitute while reducing wash-water demand.

Calcium oxide extracts phosphorous from poultry litter, preventing eutrophication while recovering minerals.

Chelating agents sequester calcium ions to release phosphate, enabling efficient struvite recovery from dairy effluent.

Air-assisted steam stripping removes ammonia from liquid waste via gas-phase transfer, eliminating foaming and pH adjustment required by traditional methods.

Solar greenhouse pre-drying concentrates biosolids to reduce volume, while fueled pasteurization eliminates pathogens for Class A fertilizer production.

Composite fertilizer blend with coated urea and fermented soybean meal maintains soil organic carbon balance while preventing phytotoxicity.

A pivotable conveyor device controls oscillating movement to distribute drying materials uniformly.

Balanced iron, manganese, zinc, and copper salts in organic fertilizer competitively inhibit cadmium absorption by rice roots.

Insect frass substitutes carbon-intensive peatlands to reduce greenhouse gas emissions while boosting mushroom yields.

Controlled drying preserves microorganism viability in solid biostimulants, maintaining agricultural productivity while reducing energy costs.

Split sludge flows collide in a pressurized chamber while air injection induces turbulence, resolving slow mechanical dewatering bottlenecks.

Organic solvents deliver polyorganic acids that liberate bound soil nutrients, preventing eutrophication from phosphorus runoff.

Composite organic boron fertilizer combines chitin oligosaccharide and wormcast with boric acid to enhance nutrient availability.

A multipurpose fertilizer composition combines hydrogel particles, organic waste, and ylang ylang extract to enhance soil moisture retention.
