Illustration of how a denitrifying bioreactor fits in with drainage water management
NOTE: This year, we’ll be highlighting some of 2015’s conservation practice innovations in a monthly series. NRCS supports science-based conservation by offering technical and financial assistance for nearly 170 conservation practice standards. As conservation science and technology advances, NRCS reevaluates each standard every five years and incorporates new advancements into conservation practice standards.
Walk to the edge of certain crop fields in Iowa and look down. You might not notice anything unusual, but just beneath the surface hordes of woodchip-dwelling microorganisms are busy removing excess nitrates from water before it leaves the field. By filtering nitrates, this organic gauntlet safeguards local streams and, eventually, the Gulf of Mexico. Read more »
Hezekiah and Francis Gibson’s non-profit organization, United Farmers USA works with NRCS staff to help other small farmers succeed through a wide range of outreach and technical assistance, educational programs and resources.
Lifelong farmer Hezekiah Gibson, and his wife Frances, farm 1,200 acres in Manning, South Carolina. They have been working with USDA’s Natural Resources Conservation Service (NRCS) for years to improve conservation on their farm.
In 2013, the couple’s non-profit organization, United Farmers USA―dedicated to helping small farmers succeed through a wide range of outreach and technical assistance, educational programs and resources―received an NRCS Conservation Innovation Grant (CIG). These grants help NRCS support public and private entities to accelerate technology transfer and adoption of promising technologies and approaches to address some of the Nation’s most pressing natural resource concerns.

Project Manager Leon New discusses the progress of the 3, 4, 5 demonstration project at a 2015 district producer field day.
In the Ogallala Aquifer region, each drop of water counts. A group of forward-thinking farmers in Texas are finding innovative ways to irrigate their crops to use water more efficiently.
These farmers are working with the North Plains Groundwater Conservation District in the panhandle to study use of water from the aquifer. The Ogallala is the nation’s largest aquifer and is being depreciated by water withdrawals at an unsustainable rate. Read more »

Farmers in the Tropics needed a better tool to estimate the nitrogen contribution from cover crops to reduce their commercial fertilizer rates.
Cover crops, which may appear as weeds to the untrained eye, are healthy plants that enhance soil health and minimize erosion. Covering the soil helps protect this precious resource that provides our food and fiber.
A calculator to address this issue was developed for Idaho and Oregon with a high success rate in legume cover crops― a type of plant, such as peas or beans, with seeds that grow in long cases (called pods). Through a Natural Resources Conservation Service (NRCS) Conservation Innovation Grant (CIG), the University of Hawaii expanded on this proven technology and modified it for tropical climates and soil types in the Pacific Islands Area.

Arkansas Rice Growers implement precise water management to reduce greenhouse gas emissions by utilizing poly pipe and alternate wetting and drying. Photo credit: Adam Chambers.
Imagine a rice farmer in Arkansas altering his water management techniques to deliver water more efficiently and use fewer days of flooding, allowing for more precise water and nutrient management while maintaining consistent yields. After a decision by the California Air Resources Board (CARB), in addition to improving water quality and reducing water use and nutrient input costs, that Arkansas farmer now has the option of selling carbon credits to large regulated emitters in California.
In 2012, California put in place a cap-and-trade program for greenhouse gas emissions, one of the most aggressive climate change programs in the world. Last week’s groundbreaking vote by CARB adopted the first crop-based agricultural offset protocol, designed to reduce methane and nitrous oxide emissions from rice production. Methane and nitrous oxide are potent greenhouse gases emitted through the cultivation and fertilization of rice fields. Read more »
Multiple cropping systems were used in the demonstration including corn and cotton. Micro-subsurface drip irrigation was one of the irrigation systems used to irrigate crops and conserve water.
In the High Plains of Texas, water reigns. The area is one of the most productive agricultural regions in the world, making a reliable water supply key to the area’s rural economies.
The High Plains draws its water from the Ogallala Aquifer, an underground aquifer that spans eight states. Currently, the use of groundwater from the aquifer is unsustainable as withdrawals for cities, farms, ranches, industries and other uses exceed the natural recharge of the aquifer. Read more »
