A farmer in Punjab once described his sandy loam field as "a sieve that lets water and fertiliser run straight through." This research evaluated biochar application at four rates (5-20 t ha⁻¹) on soil physical properties and nutrient availability in sandy loam at KVAU Ludhiana and NDUAT Kumarganj over 2021-2023. Biochar at 20 t ha⁻¹ increased soil organic carbon by 112%, WHC by 22.7%, CEC by 18.6%, and available N by 34.6% while reducing bulk density by 8.4%. Effects were dose-dependent and consistent across sites.
