The publications and other resources in this area address water use, soil moisture management, water quality, and water conservation. Topics range from created wetlands to choosing water-use-efficient crops to water quality in organic production to irrigation management. This section addresses the close relationship between agricultural production, soil moisture, crop and livestock water use, and water resources. As anyone who has tried to farm during a prolonged drought can testify, crop production depends on good management of soil moisture, whether from rain or supplemental irrigation. Livestock need clean water for healthy and productive growth. Yet, crop and livestock production can harm water quality unless good soil and water conservation practices are in use. Farmers and ranchers concerned with environmental degradation and climate change will find helpful recommendations in these ATTRA publications, and at the resource links listed in them, and in the Further Resources list, below.
