While cover crops have been shown to be beneficial in many systems, they may not work everywhere for everyone. Climate may be one predictor of how well cover crops will work. In temperate climates, cover crops can reduce runoff in snowmelt and spring rains by scavenging excess nutrients in the soil. In dry regions, where there is less concern of nutrient loss, cover crops could have negative impacts, such as reducing soil moisture and not decomposing rapidly enough for cash crops to benefit.
