Crop residues can also help reduce wind erosion and can enhance snow entrapment.
This increased P stimulates algae growth, which is followed by an increased biological oxygen demand when the algae die and decompose. This can deplete dissolved oxygen levels, resulting in game fish stress or kill. In addition to affecting sediment loss, tillage influences many interacting physical, chemical, and biological properties of soils that can have major impacts on crop production. These properties include temperature, moisture, aeration, bulk density, structure, nutrient distribution, organic matter levels, and microbial populations. Various crops respond to these changes differently.
