Crop rotations are used to manage soil and nutrients. Cover crops can be selected to take up nutrients not used by the main crops and then be plowed into the soil to provide nutrients. Water use needs to be considered when selecting cover crops because some of them could increase water use substantially.Soil management has influential interactions with pest and disease management partly because good
soil management and healthy soil help keep the plants strong and healthy and improve their resistance to pests and disease. The use of excess nitrogen in the soil can provoke some pest and disease problems, but inadequate nutrients, organic matter, or minerals can also weaken the plants and increase susceptibility to diseases.An organic farm typically uses integrated pest management (IPM) that includes biocontrol agents and practices and selective use of organic pesticides. In that context, actions can be taken to restore and enhance pest-predator balances. The mere presence of an insect pest does not necessarily constitute a problem; the decision on when to intervene is made on the basis of monitoring, using damage thresholds, and understanding the life cycles of the insects and the causes of outbreaks.Water and watershed management interact with soil, pest, and weed management to affect crop growth and environmental effects. For example, the use of excess water or inadequate drainage systems can lead to excess weeds and canopy growth that might provoke pest problems or provide a favorable environment for certain root pathogens. Appropriate soil management can decrease soil erosion and thereby can reduce sediment runoff. Soil management can also improve water infiltration into soil and reduce water use.Cover crops have many interactions with and effects upon soil, water, crops, and weeds. Planting cover crops can increase soil fertility and organic matter, increase soil biodiversity and microbial activity, prevent erosion and runoff, protect or improve water quality, attract beneficial insects, and improve soil structure.
