Biochar affected by composting with farmyard manure.
Biochar applications to soils can improve soil fertility by increasing the soil's cation exchange capacity (CEC) and nutrient retention. Because biochar amendment may occur with the applications of organic fertilizers, we tested to which extent composting with farmyard manure increases CEC and nutrient content of charcoal and gasification coke. Both types of biochar absorbed leachate generated ...
متن کاملHardwood biochar and manure co-application to a calcareous soil.
Biochar may affect the mineralization rate of labile organic C sources such as manures via microbial community shifts, and subsequently affect nutrient release. In order to ascertain the positive or negative priming effect of biochar on manure, dairy manure (2% by wt.) and a hardwood-based, fast pyrolysis biochar were applied (0%, 1%, 2%, and 10% by wt.) to a calcareous soil. Destructive sampli...
متن کاملBiochar and manure affect calcareous soil and corn silage nutrient concentrations and uptake.
Carbon-rich biochar derived from the pyrolysis of biomass can sequester atmospheric CO, mitigate climate change, and potentially increase crop productivity. However, research is needed to confirm the suitability and sustainability of biochar application to different soils. To an irrigated calcareous soil, we applied stockpiled dairy manure (42 Mg ha dry wt) and hardwood-derived biochar (22.4 Mg...
متن کاملEffect of heating time and temperature on the chemical characteristics of biochar from poultry manure.
Poultry manure (PM) chars were obtained at different temperatures and charring times. Chemical-physical characterization of the different PM chars was conducted by cross-polarization magic angle spinning (CPMAS) (13)C NMR spectroscopy and thermal analysis. CPMAS (13)C NMR spectra showed that the chemical composition of PM char is dependent on production temperature rather than on production dur...
متن کاملSoil compactibility as affected by soil moisture content and farmyard manure in central Iran
Soil compactibility which basically depends on soil texture, organic matter and soil water content during farm machinery traf®cking are major factors affecting soil conservation. In a ®eld experiment, cattle farmyard manure was applied to a silty clay loam soil (®ne-loamy, mixed, thermic Typic Haplargids, USDA; Calcaric Cambisols, FAO) in Isfahan, Iran. Three rates, 0, 50, 100 Mg haÿ1 (on oven ...
