Researchers believe integrating forage production and/or grazing with crop production
could improve water conservation due to the water-use efficiencies of forage.
Here’s a suggestion for South Plains producers looking to turn a profit while preserving
Ogallala Aquifer water: Put the cattle out to pasture.
After three growing seasons, researchers with the Texas Alliance for Water Conservation
(TAWC) have found that for growers looking to curtail their irrigation, grazing cattle
on forage land could be the most profitable use of acreage.
TAWC is an eight-year, $6.2 million demonstration project monitoring 26 Floyd and
Hale County producers who use a variety of crop and livestock grazing combinations.
By monitoring their farms over eight years, researchers hope to pinpoint growing
practices and technologies that can allow growers to continue turning a profit on
their land while at the same time preserving diminishing South Plains water resources.
“You can take other crops and make them profitable per acre, but when you look at
the yield per unit of water investment, you get a different picture. Out here, water
is a scarce resource, so we have to look at things in terms of water cost,” said
While researchers stress it is still too early in the demonstration and that the
systems under study are too complicated to draw too many conclusions as of yet, there
are some intriguing trends.
- Producers who foraged livestock or grew forage fields alongside row crops have consistently
enjoyed higher net yields for the amount of water and fertilizer used.
In 2005, for example, one TAWC grower devoted all of his acreage to foraging cattle.
He used an average 1.23 inches of irrigated water per acre and enjoyed a yield of
$125.89 per acre, or $93.34 for every inch of water he used – more than double any
other system in terms of dollar per inch of water used.
These findings confirm more than 10 years of separate studies led by Allen, testing
forages against cotton monocultures on Texas Tech’s Research Farm in New Deal.
- Sorghum requires less water than corn and can return similar profitability to the
grower per acre.
- Perennial forages have a big advantage in prevention of soil erosion, lower nitrogen
and water requirements, and have the potential to be profitable, particularly for
the amount of water invested.
- Integrating forage production and/or grazing with crop production generally improves
water conservation of the overall system because of the water-use efficiencies of

Researchers discuss ways for farmers to conserve water and enhance profitability.
Through the 26 test sites, TAWC partners are examining multiple commodities under
different management techniques. The project documents local producers who make their
own decisions on cropping and livestock practices in a variety of dryland and irrigated
systems that include cotton, corn, sorghum and small grains.
Researchers cautioned in their summary that profitability should be balanced against
the long-term ability to sustain resources. The Ogallala Aquifer, which supplies
most irrigation water for the region, is not replenishing as quickly as it is being
“Sustainable profits may differ greatly from maximum profits that are achieved with
non-sustainable depletion of natural resources,” they noted.
