253 Symposium--Science behind a Soil Conservation Practice Standard for Soil Amendments

Oral Session

ASA Section: Environmental Quality

The overall goal will be to present the science behind the development of a Conservation Practice Standards for the use of soil amendments. Specific criteria for the use of by-product gypsum as a soil amendment will be presented.
