A transformation towards sustainable food production requires improved circular nutrient management. Urban organic waste contains relevant nutrients and matter, yet only 4% of global urban nitrogen (N) phosphorus (P) sources are presently recycled. One recycling approach is the composting wastes for horticulture. We characterized compost from various fractions assessed their fertilizer value in...

A pilot-scale study was undertaken to evaluate alternatives to the solid waste management of a Central American municipal market located in Estelí, Nicaragua. The municipal solid waste from the local market is the second largest contributor to the municipal solid waste (MSW) stream. Waste from the market without any previous sorting or treatment is open dumped. The options evaluated in this stu...

Composts are commonly used as soil amendments to sustain and improve the functionality of agricultural soil. Compost has abiotic (organic matter [OM], nutrients) biotic characteristics (microorganisms) both can influence microbiome. The compost, in turn, depend on properties compost such maturity. Few studies have investigated relative effects components microbial community crop growth. To brid...

Phosphorus (P) fixation in the soil reduces utilization of this element by plants and can be one main problems for fertilization management soils containing Fe oxides. As a strategy to minimize effects P retention, organic materials, such as biochar or commercial composts, may useful tools maintain availability delay immobilization soil, thereby benefiting, example, rehabilitation areas impacte...
