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 (...

to study the effect of different fertilizing systems on macro and micro nutrients uptake by annual medic (medicago scutellata cv. robinson) an experiment was conducted under dry farming and irrigated conditions at two research stations (sararood dryland agricultural research institute and soil fertility research station in mahidasht) during 2009 growing season. the experimental treatments consi...

documenting the production process in agriculture includes providing all information and activities that shows the course of production from seedbed preparation stage to harvest stage. for this purpose, in present investigation all management operations performed from seedbed preparation stage to harvest stage in the studied wheat fields in 2007 and 2008 were recorded through farms survey. in t...

Biochar has been suggested for application in acidic soils increasing agricultural productivity, as it may result the benefits of sustainable carbon offset into and soil fertility improvement. However, role biochar enhancing nutrient bioavailability plant performance is manifested through complex interactions biochar-soil-plant. Moreover, not yet known how a crop-residue-derived would perform w...

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...
