Abstract: For exploring the optimum ratio to substitute inorganic fertilizer in Fluvo-aquic soil, the field experiment with different organic material substitute different ratio of inorganic fertilizer was carried out. Compared with CK, the basic soil nutrients contents were improved under the treatments with different ratio of organic material substitution. Soil organic matter (13.4 g/kg) and available nitrogen (93.99 mg/kg) content were significantly elevated under 40% of inorganic fertilizer substitute by straw (S3) treatment. Soil total nitrogen (0.90 g/kg), available phosphorus (2.94 mg/kg), and available potassium (224.97 mg/kg) content were significantly higher under S3, 30 and 40% inorganic fertilizer substitute by straw and cattle manure combination (MS2 and MS3). The highest DOC content (15.45 mg/kg) occurred under S3, while highest DON content (12.88 mg/kg) appeared under MS2. The highest aromaticity index was under MS2. In sum, the organic material substitution different inorganic fertilizer was benefit to improve soil properties. Therein, 40% of inorganic fertilizer substitute by straw alone or 30 - 40% of it substitute by straw and cattle manure combination was the optimum ratio in Fluvo-aquic soil in Henan province.
