Abstract Biochar has been shown to improve soil properties and plant productivity in soils with inherently low fertility. However, little reported for upland corns under dry wet precipitation regimes. This study investigates the effect of biochar addition on a range physicochemical, biological, hydrological properties, corn growth agrometeorological drought conditions. Here, experiments were laid out randomized complete block design three replications at two sites during 2017 2018 South...

ABSTRACTApplying soil amendments such as biochar has been proposed a means to improve properties and reduce greenhouse gas emission from agricultural soils. The objective of this study was evaluate compare the effects straw application on rice yield, select properties, global warming potential (GWP), intensity (GHGI) over 3-year period. treatments included control (CN), barley (BC, 2,000 kg ha−1), (BS, BC+BS (each 1,000 ha−1). During rice-growing season, significant interactive BC BS...

This study was undertaken to investigate crop productivity, nitrogen use efficiency (AE_N, agronomic of N; ARF_N, apparent recovery fraction N), and nitrous oxide (N2O) emission after biochar (BB, bamboo biochar) fertilizer (N) application in paddy upland agricultural soils. The selected rice Chinese cabbage were grown the soil soil, respectively. Each treatment group, comprising N100% (N, 90 kg ha−1 for rice; 320 cabbage), BB + N35%, N70%, N100%, separated by a Control treatment. Overall,...

The purpose of this study was to produce rendering animal carcass residue char (RACR-C) by pyrolyzing the solid residues low-recyclable rendered pig carcasses and evaluate their cadmium (Cd) adsorption characteristics mechanisms.

Rendering process is known as a quick and stable method that copes with dead livestock by extracting purifying the animal’s fat others through heat treatment at high temperature pressure. However, large amount of solid byproducts equivalent to 15% weight carcasses after this are discharged, some them provided feed compost, but landfilled since processed must go secondary again. It judge RACR (rendering animal carcass residue) has utilization value it composed protein bone tissues very...
