This research evaluates the effects of treating biochar with buffalo slurry on soil quality, nutrient retention, and wheat development. Treating biochar in the slurry for twenty-four hours increased its carbon and nitrogen contents significantly. Applying this enriched biochar to soil reduced nitrification by 94 percent, ammonification by 74 percent, and carbon dioxide emissions by 92 percent compared to untreated controls. It also substantially curtailed the leaching of vital minerals, including nitrogen, potassium, phosphorus, and carbon. Furthermore, the enriched biochar enhanced soil microbial biomass, enzyme activities, bulk density, and pore density. These soil improvements translated into superior mineral uptake and better overall agronomic growth attributes in wheat crops compared to standard biochar and control conditions.
Nutrient run-off and greenhouse gas emissions from agricultural soils threaten environmental sustainability and deplete soil fertility. Using enriched biochar reduces the leaching of vital nutrients into water systems while cutting soil carbon dioxide output. This approach offers a potential pathway to enhance crop development and improve soil health using readily available animal waste.
This work points towards an applied soil amendment technique suitable for agricultural producers and biochar manufacturers seeking to improve crop nutrition. Enriched biochar combines livestock waste with carbon materials to decrease fertiliser loss and boost wheat performance. Because the findings derive from an experimental study comparing specific treatment ratios, the solution represents applied and tested research requiring scale-up and field validation before commercial deployment.

The present investigation was conducted to understand the role of enriched biochar on soil nitrogen and carbon dynamics, leaching losses of nutrients, and growth attributes of wheat. Buffalo slurry (BS) was used to enrich the biochar for 24 h and 2% biochar (SB) or enriched biochar (SEB) was used. Enrichment of biochar with BS as SEB improved the C and N contents of biochar by 33–310% and 41–286% respectively. The application of biochar (SB) and enriched biochar (SEB) reduced the net nitrification by 81% and 94%, ammonification by 48% and 74%, and carbon dioxide by 50% and 92% respectively as compared to control. The leaching losses minerals i.e., C (by 30%), N (by 125%), P (by 50%), K (by 82%), Na (by 9%), Ca (by 24%), and Mg (by 12%) was decreased in SEB treatments compared to control. The soil enzyme activities, microbial biomass (MBC and MBN), wheat agronomy, soil bulk density and soil pore density, mineral uptake from the soil, and mineral contents in the plant body were improved in the SEB as compared to SB and control treatments. Our results revealed that the biochar enrichment process could improve the C and N storage in the soil reservoir and lower the environmental risks to soil and water.
