Common bean is usually cropped under rainfed conditions and in soils with low pH water retention, the sub-humid semiarid regions of Brazil. To improve soil conditions, smallholder farmers commonly use cattle manure. However, manure available limited amounts, insufficient to fertilize all cropping areas. Thus, other amendments, such as poultry (PM) biochar (BC), have been proposed increase reten...

Abstract Soil pH is one of the main drivers soil microbial functions, including carbon use efficiency (CUE), microorganisms in converting substrate C into biomass, a key parameter for sequestration. We evaluated liming effects after maize-litter addition on total CUE (including residues), biomass (CUE MB ), and fungal an acidic Acrisol with low C. established 6-week incubation experiment to com...

Objetivo: Evaluar los indicadores físicos de la calidad suelos sometidos a cuatro usos distintos en Lixisols Objective: To evaluate the physical indicators of quality soils subjected to four different land uses in from La Sabana Huimanguillo, Tabasco, Mexico. Design/methodology/approach: Nine variables were evaluated soil samples located Sabana, Huimanguillo: infiltration rate, resistance penet...

The objective of this study was to evaluate the performances three cassava genotypes on yield, physiology and morphological traits under different fertilization regimes. A field experiment conducted in a split-plot design for two consecutive seasons Mansa district Luapula Province Northern Zambia highly weathered Chromi-haplic Acrisol soils. Four regimes, control-M3, lime-M1, NPK fertilizer-M4 ...

Loamy sand soils of the southeastern USA Coastal Plains often have poor physical properties because they contain cemented subsurface hard layers that restrict root development and yield. Their physical properties can be improved by adding amendments. Polyacrylamide (PAM) amendments and/or organic matter (OM) in the form of ground wheat (Triticum aestivum L.) stubble or pecan (Carya illinoensis)...

Soil organic C (SOC) and total soil N (TSN) sequestration estimates are needed to improve our understanding of management influences on soil fertility and terrestrial C cycling related to greenhouse gas emission. We evaluated the factorial combination of nutrient source (inorganic, mixed inorganic and organic, and organic as broiler litter) and forage utilization (unharvested, low and high catt...
