Students Get Schooled by Schools of Fish

USDA Under Secretary Cathie Woteki reviews the hydroponic garden at Food and Finance High School in New York City, which is fed nutrients from sediment collected in Dr. Warner’s basement fish tanks and pumped up four floors to the garden.

Schools of fish may be common things to see, but watching some fish school high school students from a basement in Manhattan’s West Side is a different experience altogether. Cathie Woteki, USDA’s Chief Scientist and Under Secretary for Research, Education and Economics, observed such a program recently during a visit to Food and Finance High School in New York.

There on West 50th Street, Cornell University operates laboratories that represent the latest in scientific technology to raise fresh, clean fish in addition to garden produce in a sustainable urban setting. Renowned Cornell scientist and educator Philson Warner developed a system for continuously re-circulating and reconditioning water to raise more than 10,000 tilapia and other fish at a time in the basement lab. The nutrient-rich water from the fish is then transferred to a hydroponic garden located a few floors up on campus. That garden produces nine types of lettuce, Chinese cabbage such as bok choi, and a variety of herbs that include sweet basil, oregano, thyme and parsley. The plants then clean the water, which is sent back to the fish. Read more »

A solid education is crucial to those seeking careers in animal science. However, many student loans can be burdensome. But a student loan payment the size of a mortgage couldn’t stop someone who has wanted to be a veterinarian since they learned to talk. Dr. Annie Bowes is one of those people.

After acquiring the knowledge to begin her dream career, Dr. Bowes was left with overwhelming debt.  Luckily for this Idaho-based veterinarian, she wasn’t left alone to repay it. In 2011, she received assistance through the Veterinary Medicine Loan Repayment Program (VMLRP) a program funded by USDA’s National Institute of Food and Agriculture (NIFA). Read more »

USDA Seeks Variety to Help American Agriculture Flourish

While most of the country is braving cold and blustery winter conditions, farmers and gardeners are busy looking ahead to the spring. They are contemplating the variety of seeds or the plants that they will use. The USDA’s Agricultural Marketing Service (AMS) increases the options for our farmers, gardeners, and plant breeders by making sure there is an abundance of varieties available.

We do this through our Plant Variety Protection Office (PVPO), which grants certificates of intellectual property protection to developers of new plant varieties. These certificates enable breeders to market their variety exclusively for 20 years. The protection is an incentive for the development of new and improved varieties. Read more »

Reflection, celebration, and ambition are hallmarks of entering a new year. We reflect on the challenges we faced, celebrate our accomplishments, and set goals for the future. For businesses, a common goal is finding new ways to satisfy ever-changing consumer demands. Our nation’s farmers and ranchers rely on research and promotion programs to help meet these demands, connecting consumers to their quality products. With a focus on highlighting quality products and building consumer trust, many research and promotion groups embarked on new initiatives and continued to expand on others in 2014.

Success for agricultural businesses often depends on their ability to provide consumers more information. The American Lamb Board accomplishes this by providing locations where lamb fans can enjoy this tasty product. Not only does the Lamb Locator list farmers markets, grocers, butchers and restaurants selling American lamb, it also includes a list of wholesale suppliers. Making this information available to the public helps more and more people enjoy quality lamb products that are produced by American farmers and ranchers. Read more »

Meet Your Wellness Goals in the New Year with the USDA DRI Calculator for Healthcare Professionals App

New “USDA Dietary Reference Intakes (DRI) Calculator for Healthcare Professionals” app allows users to keep track of nutrient calculations and recommendations based on the DRI values.

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 USDA National Agricultural Library’s (NAL) Food and Nutrition Information Center (FNIC) today launched its mobile application, or “app,” which calculates Dietary Reference Intakes (DRIs).  The “USDA Dietary Reference Intakes (DRI) Calculator for Healthcare Professionals” app allows users to keep track of nutrient calculations and recommendations that are based on the DRI values in a more convenient and user-friendly format. Through this new app, healthcare professionals can save time in the nutrition care process for patients and clients, while having access to credible nutrition guidance.

The National Academy of Science’s Institute of Medicine first developed the DRIs in the mid-1990s. DRIs are recommended amounts of each nutrient a healthy person should consume to prevent deficiency or harmful health effects. Initially presented in tables, this information allows healthcare professionals to use the DRIs to assess and plan diets for groups or individuals. For example, if you are a female between 19 and 50, your registered dietitian or doctor may recommend that you increase your dairy consumption to meet the 1,000mg/day calcium recommendation outlined in the DRIs. The DRIs are also used in policy-making such as setting calorie and sodium guidelines for healthy school lunches. Read more »

U.S. Farms, Large and Small

Small family farms dominate the total U.S. farm count and occupy more than half of U.S. farmland, but midsize and large-scale family farms account for the bulk of agricultural production. (ERS Family Farm Report, 2014 Edition)

Describing the structure of the U.S. farm sector is challenging, because farms vary widely in size and other characteristics.  Are they largely family businesses, or corporate operations?  U.S. farms range from very small retirement and residential holdings to businesses with sales in the millions of dollars. And descriptions based on U.S. averages hide much of the variation.

The Economic Research Service prepares periodic reports on family farms that provide detailed information for policy makers and others interested in farm policy and the farm sector.  The reports draw on data from a scientifically designed USDA survey, the Agricultural Resource Management Survey, or ARMS.  The survey, conducted annually, covers all types of farms, and is designed to accurately represent farms and farm households, including financial conditions and production practices.
