We worked on efficacy of herbicides (pre-emergence) by mixing with compost-fertilizer mixture in transplanted rice (above saturation soil moisture) and observed it at par with application as sand-mixture. Mixing herbicide with compost decreases microbial population significantly in compost, but did not affect soil microbial population (30 days after application and harvest of crop), available nutrients (N, P, K) in soil, and enhanced grain yield significantly over recommended practice. Is there any work on applying herbicide by mixing with compost in dry soil?
