Water

ARS researchers are helping farmers save on water usage costs while maintaining good crop yields.

ARS developed sensors and automated irrigation control systems that will result in significant savings and increases efficiency for farmers.

A novel approach for determining the effectiveness of conservation practices in reducing nitrate losses.

Pumping groundwater from local aquifers to irrigate crops has increased yields but is steadily reducing the supply of available water for future use.

An ARS research team along with the Southwest Climate Hub in Las Cruces, NM, developed a resource called The Water Adaptation Techniques Atlas.

Study finds ammonium nitrate had 34% lower yield compared to poultry litter treated with alum.

The "Haney Test" is an award-winning soil health tool that major soil testing laboratories are quickly adopting to determine optimal soil fertilizer rates.

To support efficient water management, ARS researchers developed an open-source model, pyfao56, for precise crop water management.

Scientists found that fish raised in reused water faced significantly higher mortality rates that those grown in tanks supplied with fresh spring water.

ARS researchers investigated whether vegetative filter strips could remove excess nitrogen from runoff.

A team of researchers and their partners have found another way to conserve water: late planted corn.

ARS scientists have come up with a game-changing water purification technology to remove nitrogen from wastewater at one-third the cost of existing technologies.

Scientists have saved millions of gallons of water by developing an automated irrigation scheduling system that targets water to where and when it is needed most.

ARS scientists are working with satellite imagery in collaboration with grape growers to improve irrigation water management on vineyards that stretch across thousands of acres.

Reducing tillage timing and frequency on 4 million acres of low-precipitation-zone wheat can save 1.75 million gallons of diesel fuel annually.

ARS, in collaboration with NASA, developed the iSnobal model--a new technology for forecasting water supply derived from melting snow.

ARS scientists made significant enhancements to the Soil and Water Assessment Tool.
