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.

“Nothing motivates me quite like being told I can’t do something. They told me no-till doesn’t work here, and you’re not supposed to be able to grow any type of canola. Well, look around. Here we are.”
When Douglas Poole speaks, you can hear the passion in his voice for healthy soil and how it has helped his farm. Poole wasn’t always a soil health proponent; he used to be an accountant. Read more »
USDA scientists work 365 days to provide safe and sustainable food, water, and natural resources in the face of a changing climate and uncertain energy sources. To recognize the contribution that agricultural science and research makes in our daily lives, this week’s “Banner Year” series features stories from 2015 that show the successes that USDA science and statistical agencies made for us all.
Making a success in agriculture and rural communities in today’s competitive world requires a toolbox of cutting-edge knowledge and ways to put that information in people’s hands so they can put it to work. Whether it’s designing these tools, developing the data to prove them, or breeding a new crop variety to outwit a plant disease to avoid a harvest’s devastation, the scientists of USDA’s Agricultural Research Service (ARS) are always coming up with something new to enhance rural opportunities.
Here are five research highlights from 2015 you should read: Read more »
Cameron Green stands among the tomatoes in the high tunnel she operates with Eric Wittenbach.
Some people leave a legacy for their children. Cameron Green and Eric Wittenbach plan to leave theirs to Mother Nature.
A philosophy of sustainability guides them on their eight-and-a-half-acre farm in Okanogan, Washington. Green and Wittenbach both come from a background of working the land; picking fruit in commercial cherry orchards, pruning and thinning threes, and growing vegetables in the Methow Valley for a local CSA. This has given them a close connection to nature, and when they bought their land eight years ago, their intentions were to make it as sustainable as possible. Read more »

Last spring, USDA’s Natural Resources Conservation Service (NRCS) in Minnesota named five watersheds eligible for funding through the Mississippi River Basin Healthy Watersheds Initiative (MRBI). Dobbins Creek, located in Mower County, was one of the selected watersheds.
About 25,700 acres in size, the Dobbins Creek watershed winds through prime farmland and flows along the northeast edge of the city of Austin. NRCS has committed $488,000 for conservation activities in the watershed over the next 5 years and obligated $51,402 through its Environmental Quality Incentives Program (EQIP) in fiscal year 2015.

Whether you’re a home gardener or a commercial grower of vegetables, cotton, or other agricultural crops, as soon as the growing season is over, you may want to consider planting cover crops—grasses, legumes and small grains that protect and improve the soil.
Cover crops, which are typically grown off season, help reduce soil erosion, increase organic matter and control weeds. At the same time, they can lessen the effects of extreme weather conditions such as drought and help improve water and air quality as well as wildlife habitat. Read more »
