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 »
The hens rotate 72 hours behind the cattle herd to provide insect control, and the bus provides easy mobility from paddock to paddock.
When bison roamed the Great Plains, prairie chickens and other fowl played an important role as the clean-up crew. They would follow the herds feasting on the larvae in bison manure.
In Doug Darrow’s 160-acre mob grazing system near Oxford, Iowa, his 300 chickens have the same job, but they ride in style from paddock to paddock in an old school bus that doubles as a chicken coop. “This means there are fewer flies to pester the cows,” said Darrow. This natural form of pest control, improves herd health and rate of gain, while providing another income source from the eggs laid by the clean-up crew. Read more »
These two soil samples are the same soil type. The one on the left is after 11 years of continuous no-till farming. The one on the right is conventional tillage.
No-till farming used to be only about reducing soil erosion. Today, continuous no-till is the preferred tillage system in some areas. Why? It’s all about soil health.
The loss of organic matter in soil, which is the lightest soil component and the first to wash away, is the healthiest portion of our topsoil. It is the house where the biological systems in our soils live and includes everything from the tiniest organisms like bacteria, algae, fungi, and protozoa to the more complex nematodes, micro-arthropods (think tiny spiders), and the more visible earthworms, insects, small vertebrates, and plants. They are all part of healthy soil. Read more »
Becoming a certified organic producer presents a unique set of restrictions and challenges. Oregon Farmer Chris Roehm overcomes those challenges with the help of a powerful ally: healthy soil. Photo by Bob Stobaugh
For agricultural producers, it’s an age-old question: How do you grow the largest, healthiest, most-profitable crops possible? Oregon organic farmer Chris Roehm says the secret is in the soil.
Co-owner and operator of Square Peg Farm in Forest Grove, Roehm is among a growing number of producers, both conventional and organic, who are realizing the benefits of improving the health and function of their soil through working with USDA’s Natural Resources Conservation Service (NRCS).
