Effects of Different Mechanized Organic Fertilization Methods on the Soil Physicochemical Properties of Corn Field

In this study, corn continuous cropping soil was sampled and five mechanical tillage and fertilization methods were compared, so as to explore the influences of different organic fertilization methods on soil physicochemical properties, and to provide reference for finding the best continuous soil fertilization methods and solving soil fertility decline in the future. The soil and corn samples were collected and measured to analyze soil physical and chemical properties and corn yield. The results showed that the mechanical spreading of decayed cow dung improved soil structure enhanced soil water retention and increased soil organic matter content. Straw mulching and breaking surface application can increase effective soil porosity, improve soil surface characteristics, improve soil ventilation and water permeability, which is expected to play an important role in improving soil surface compaction. The deep application of straw into the field can improve the soil viscosity and high fertility, and can be used in good sandy soil. Particle organic fertilization can effectively improve soil water permeability without causing loose soil texture, improve soil water permeability and water retention, and increase pH value of acidic soil.
