Overview

Laboratory incubation study demonstrates organic amendments mitigate fungicide-induced soil degradation in orchard soils, highlighting vermicompost as an effective soil-fertility enhancer.

Key Points

To evaluate the efficacy of four organic amendments in counteracting the adverse effects of repeated fungicide applications on soil physicochemical properties and nutrient dynamics in temperate apple orchard soils.
Conducted a 60-day laboratory incubation of temperate apple orchard soil using a completely randomised design with 25 treatments and three replications.
Evaluated four organic amendments (vermicompost, farmyard manure, spent mushroom compost, Trichoderma-fortified compost) applied alone and in combination with four fungicides (captan, propanib, flusilazole, difenoconazole).
Measured soil pH, electrical conductivity, organic carbon, and available nitrogen, phosphorus, and potassium at 0, 30, 45, and 60 days post-treatment.
At 60 days, vermicompost alone yielded soil pH of 6.11, organic carbon of 1.238%, available nitrogen of 484.7 kg ha⁻¹, phosphorus of 31.0 kg ha⁻¹, and potassium of 177.8 kg ha⁻¹, compared to 6.85, 1.000%, 449.5 kg ha⁻¹, 24.6 kg ha⁻¹, and 146.7 kg ha⁻¹ in controls.
All organic amendments increased organic carbon and available macronutrients over time, whereas fungicide-only treatments exhibited lesser changes.
Fungicide–organic amendment combinations consistently maintained higher nutrient levels and organic carbon compared to corresponding fungicide-only treatments, with vermicompost demonstrating the most pronounced response.
