Biochar is a source of stable organic matter being explored as manure additive. A 64 d incubation experiment was conducted to quantify the short-term effect (RM), biochar–manure (BM), raw biochar (BC), RM + BC, and BM BC amendment on soil carbon (C) nitrogen (N) mineralization. Manure increased CO 2 -C emission rates, with highest cumulative emissions observed for BC. Treatments halted C minera...

The current study is focuses on a sustainable agricultural ecosystem for soil fertility and human health improvement. To estimate the effects of applying organic amendments (compost, vermicompost, biochar, manure rapeseed cake) crop growth maize nutrient uptake in calcareous soil, eleven treatments were studied, which included compost (CM), cow vermicompost (CMV), pig (PMV), biochar (BCV), (BC)...

in order to investigate effect of organic manure and super absorbent on physiological and biochemical traits of potato (solanum tubersum, cv marfona), a split plot experiment was conducted as randomized complete block design with three replications at research farm, agriculture college, university of razi in 2010. main factor included two levels of super absorbent a200 (0 and 70 kg/ha,) and spl...

In sustainable agriculture, protection of the ecosystem and reduce chemical fertilizers are the main goals. Nowadays, sweet basil, one of the best general fragrant foliage, is considered as an industrial plant. In present study to compare different levels of cow manure biochar (CMB) and humic acid (HA) on vegetative traits and mineral absorption rate of green basil plants, an experiment was con...

Poultry manure (PM) has become a serious environmental problem due to large scale of industrial production and unsustainable management, causing emissions greenhouse gases (GHGs), odors, leakage nutrients as well inorganic, organic biological pollutants. The main goal this review was get better understanding carbon, nitrogen, phosphorous cycles in processing poultry with the most common technol...

Sub-Saharan Africa (SSA) experiences soil degradation, food and livelihood insecurity, environmental pollution and lack of access to energy. Biochar has gained international research attention, but few studies have investigated the potential of biochar to address the challenges in SSA. This paper seeks to identify and evaluate generic potential opportunities and constraints associated with bioc...

Biochar application to the soil can improve quality and nutrient leaching loss from swine manure adapted soils. Our working hypothesis was that biochar-incubated with could be a better amendment than conventional application. The manure-biochar would decrease increase plant-available nutrients. study objectives were 1) assess physicochemical properties of mixture after lab incubation 2) evaluat...

Introduction Continuous monoculture leading to soil nutrient depletion may cause a decline in plantation productivity. Cow dung is typically used as cheap renewable resource improve status. In this study, our purpose was compare the effects of different cow return methods (direct and carbonization return) on microbial communities phosphorus availability root zone (rhizosphere non-rhizosphere so...

Biochar produced during pyrolysis has the potential to enhance soil fertility and reduce greenhouse gas emissions. The influence of biochar properties (e.g., particle size) on both short- and long-term carbon (C) mineralization of biochar remains unclear. There is minimal information on the potential effects of biochar particle sizes on their breakdowns by soil microorganism, so it is unknown i...
