2026-09-15 A method for full straw returning based on field composting of organic fertilizer under a conservation tillage model for corn in the Northeast region doi:10.57760/sciencedb.iga.0016s en This dataset centers on the core technologies of field composting of organic manure and full straw return under conservation tillage patterns for corn in Norheast China. It integrates comprehensive field trial data associated with patents, covering five core categories: composting process, process monitoring, product quality, return effect, and economic benefits. The core dta includes: basic parameters for field composting (straw collection area ≥2ha, corn straw crushing length 5-35cm, stubble heght 20-30cm, pile specifications ≥10m×4m×2.5m, composting cycle from mid-November to March of the following year); raw material ratio daa (molasses-urea-superphosphate solution ratio, total mass of straw and livestock manure, components and dosage of low-temperature microbial agents, moisture content control range); dyn data of the composting process (pile heating duration, duration of temperature ≥50℃, turning frequency and timing); organic fertilizer quality data (maturity, moisture cntent 30%-40%); agronomic data for return (furrow application depth 10-20cm, organic fertilizer application rate 20-25t/ha); soilement effect data (soil organic matter, total nitrogen, available phosphorus, available potassium content); and economic benefit data (fertilizer input cost, chemical fertilizer reduction ratlso includes comparative trial data for examples and control groups, comprehensively reflecting the practicality and application effectiveness of this technology in the cold regions of Nort conservation tillage; organic fertilizer; field composting; full straw returning to the fi; corn PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
