Seems like there’s an “app” (application) for everything these days—perhaps because mobile phone use is becoming increasingly global. USDA’s Agricultural Research Service (ARS) soil scientist Jeff Herrick and colleagues have jumped on that trend in their efforts to promote sustainable land-use practices and world food security.

This past April, they released the first two of a suite of mobile phone apps that, once all are issued, will connect agricultural producers around the world and provide them with shared knowledge on ways to maximize their land’s productivity while protecting its resources for future generations.

Today is World Statistics Day and countries all around the world are celebrating the impact accurate statistics have on their lives. Here at the National Agricultural Statistics Service (NASS) we take pride in our long tradition of working with our counterparts around the globe. Not only are we actively networking with other United Nations member states, but we also partner with Canada and Mexico to cooperatively publish statistics. Read more »

STEM Grows from SEEDS at San Diego College

Educators at Mesa College, in San Diego, Calif., are developing future leaders in agricultural sciences and related fields by providing them with a solid background in science, technology, engineering, and mathematics (STEM) education.

The STEM Engagement for the Enrichment of Diverse Students (SEEDS) program is a four-year effort to encourage underrepresented students, primarily Hispanic, to pursue graduate degrees.  The U.S. Department of Agriculture’s National Institute of Food and Agriculture is supporting the project with a $290,000 grant.

A Diet to Help Conserve Bees When Food Is Scarce

Bees eating MegaBee

MegaBee, an artificial diet developed by ARS and S.A.F.E. R&D, LLC, helps sustain honey bees in the face of pressures such as poor nutrition, pathogens, parasites and sublethal exposure to pesticides.

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.

The fact that honey bees are a critical link in pollinating plants, especially our crops, has become better known to the public in the past few years. In exchange for their labor, flowers provide bees with pollen and nectar as food. But few people wonder what’s available for bees to eat when there are few plants blooming in the late fall and early winter.

During such times of the year, with little natural food available, honey bee colonies usually fade a little. But this is exactly the time of year when beekeepers want their colonies to be producing lots of healthy, robust bees ready to be trucked to California to plunge into pollinating millions of almond blossoms in February.

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 »

Preserving “Heirloom” Collections – Microbial, That Is

As a plant pathologist with USDA’s Agricultural Research Service (ARS) Rice Research Unit in Beaumont, Texas, Toni Marchetti oversaw a new program in 1972 to develop new cultivars that better resisted costly diseases like rice blast.  

Marchetti retired from ARS in 2001, leaving behind not only a legacy of excellence in rice breeding and plant pathology, but also a prized collection of 1,000 rice blast specimens he isolated from Texas, Arkansas, and other rice-growing states. The Beaumont unit was closed in 2012, and the collection was relocated to ARS’s Dale Bumpers National Rice Research Center in Stuttgart, Arkansas. Read more »
