The aim is to compare the effects of organic versus inorganic fertilizers on soil chemical properties in spinach production.
Field experiment conducted in Rajshahi University using randomized complete block design (RCBD) with three replications.
Six different fertilizer treatments were applied to assess their impact on soil properties.
Each treatment was evaluated for changes in soil organic matter, macronutrients, and micronutrients from pre-cultivation to post-harvest.
Treatment T5 showed the highest net gain in total nitrogen (+0.04%) and available phosphorus (+2.20 mg/kg).
Control (T0) and T2 experienced significant phosphorus depletion (up to -10.02 mg/kg).
T5 minimized sulfur loss (-1.46mg/kg) while maximizing zinc accumulation (+0.08mg/kg).
Most treatments led to a decrease in soil organic matter, with an inverse relationship observed with total nitrogen.
