My research focuses on the effects of biochar and farmyard manure (FYM) with residual nutrients on crop yield and soil fertility in degraded soils. In your experience, what combinations or rates of application work best to increase soil organic matter and nutrient retention? Are these amendments most effective in particular soil types (such as sandy soil or low pH)? What difficulties have you encountered, such as those related to FYM quality or biochar production? To promote sustainable soil management techniques, disseminate your research or field data. For related studies, check out my ResearchGate profile!
To optimize the application rates of biochar and farmyard manure (FYM) for improving soil fertility and crop yield in degraded soils, you can use a data-driven approach like Response Surface Methodology (RSM) with Design-Expert software. This method allows you to model the interactions between FYM and biochar at various rates and assess their impact on key soil and plant parameters.@Bishal Dhungana
Please consult a biometrician with what you wish to learn and the resources you have to address the question.
To make long-term changes in degraded soils you may need 50 dry t/ha of farmyard manure
