The Ogallala aquifer in Eastern New Mexico is in dramatic decline with only a few years of groundwater left by some estimates. For this field day, we’re returning to Host Glenn Duff, who responds to this acute crisis by experimenting with different forages in four fields, three with center pivots. In order to conserve water and prioritize soil health, Glenn planted perennial pasture and uses cover crops in annual grain rotations. Instead of harvesting alfalfa which removes biomass, he grazes it with his small herd of cattle, feeding the soil at the same time.

Rajan Ghimere (NMSU’s Cropping Systems and Soil Management Research Laboratory) will present associated research his team is carrying out at Glenn’s fields.

After a communal lunch, the day will continue at the Clayton Livestock Research Center with presentations by the USDA Southwest Climate Hub.
