Biochar is a stable carbon-rich material whose potentials can be greatly enhanced by modification with simple treatments. Easily available two different biochars such as rice stubble biochar (RSB) and saw dust (SDB) were slowly pyrolyzed (450±50°C) modified KOH RSB-M SDB-M respectively. Represented analyzed to know their physicochemical characteristics nutrient contents. Results revealed that c...

CO2 emissions represent one of the greenhouse gases significantly affecting climate change. Reduced tillage practices can contribute to mitigation from soils. The effect with different straw incorporation on was studied in field experiments years 2020 and 2021. winter wheat used 2020, spring barley Treatments were: (1) chiselling 10–12 cm; (2) shallow (5–6 cm depth); (3) mulch, (4) stubble. war...

A three-year field experiment investigated the potential yield benefits and soil effects from over winter cover crops in Scotland, U.K. Brassica composition of significantly increased grain nitrogen (N) concentration following spring barley crop. The with was outweighed by costs thus without subsidy (Ecological Focus Area) payments there decreased profitability for Cover crop were mostly neutra...

Asian countries, despite being the largest producers and yielding a significant proportion of world’s rice, have poor disposal facilities for harvested rice straw (stubble). Due to higher costs in their handling relative value, local farmers prefer burning stubble fields, thus creating environmental problems. Even though government has taken initiatives, no effective solution been discovered ha...

Passive microwave remote sensing techniques can be used to monitor freeze/thaw at frozen soil surface. Researches found that the negative spectral gradient at 19GHz and 37GHz was a good criteria for decision of frozen soil[1]. At vegetated area, to make the algorithm simple, vegetation scattering were ignored, only their attenuation were considered, which were kept constant, regardless of veget...
