Abstract: The objective of this work was to evaluate the performance thermopotassium and thermophosphate agrominerals, as sources P K, in an organic pasture consortium 'Marandu' Urochloa brizantha + Stylosanthes spp. Brazilian Cerrado. management compared with conventional farming using chemical fertilizers, during three years, two adjacent experiments, one other without previous growth green m...

The generation of green waste is increasing rapidly with population growth in China, and green waste is commonly treated by composting. The objective of this work was to study the physical and chemical characteristics of composted green waste as affected by a two-stage composting process and by the addition of brown sugar (at 0.0%, 0.5%, and 1%) and calcium superphosphate (Ca(H2PO4)2·H2O) (at 0...

A pot experiment was conducted to investigate the effect of biochar-compost on availability P for maize cultivation in a concretionary Lixisol northern Ghana and residual soil characteristics thereof. Sawdust biochar co-composted with kitchen waste cow dung various proportions. Four biochar-composts were selected based their superior carbon available content, lower pH, electrical conductivity (...

Irrational phosphorus (P) nutrient management practices often fail to match of P fertilizer type, soil transformation and crop demand, lead increased accumulation legacy P, reduced PUE, pollution, affecting production. A pot experiment incorporating types (SSP, simple superphosphate; CMP, calcium magnesium phosphate; DAP, diammonium TSP, triple APP, ammonium polyphosphate; CK, no application) e...

Rock phosphates are less soluble and agronomically not as efficient the acidulated. However, some rhizobacteria can improve solubilization of inorganic in soil, raising efficiency rock phosphates. The objective was to evaluate development maize plants response application P sources associated with inoculation. A greenhouse experiment carried out six sources: no application; ​​Triple Superphosph...

The benefits of applying phosphogypsum to the soil are widely known. However, effect on phosphate fertilization efficiency is still unclear. A long-term field experiment was performed an Oxisol in Parana State, Brazil evaluate effects triple superphosphate (TSP) and application rates nutrition grain yield soybean, wheat, black oat under no-till. Applying TSP sowing furrow soybean wheat increase...
