There are many ways to conserve water in agricultural settings including increasing the water storage potential in the soil, capturing irrigation runoff and stormwater, and reducing water use to match crop needs. Increasing water storage potential in soil can be done through several methods that increase the carbon content or water absorption into the soil. Practices including composting, crop rotation, reduced tillage, mulching, land smoothing, cover crops and biochar. Water harvesting can include collecting the water for future use or allowing infiltration into groundwater. Cleaning the water of pollutants is an important aspect to consider in developing storage and infiltration solutions. Water harvesting and water storage technologies include designing ways to collect and store rainwater, sediment basins, vegetated treatment systems and woodchip bioreactors.

Cover Crops
Low residue cover crops or winter fallow vegetable production fields
Source: UCCE | Cover crops planted in fallow vegetable fields are an effective cultural practice for reducing erosion and protecting water quality during the winter. By reducing run-off volume and protecting the soil from erosion cover crops also minimize sediment and nutrient loads during rain events, and by taking up residual soil nitrate, they minimize nitrate leaching.
