1. How Fertilizer Dealers Use Research Information There i s not a great deal o f resource information t o draw from i n reference t o the t i t l e so most o f my comments are based on observations made and personal opinions formed during some 26 years of experience in the fertilizer industry, covering a majority of the principal agricultural states. Fertilizer dealers as a whole tend t o translate research information into dollars. They use it as a business tool. It provides support t o the sale of existing products and services and identifies... Download paper
2. Nitrate Testing Clinics Thirty-eight nitrate testing clinics were held in 36 Michigan counties in the spring of 1989. A mobile testing van was equipped for nitrate analysis of soil and water samples. Over 2,200 soil samples and 1500 water samples were analyzed for nitrate N using the nitrate ion-specific electrode. More than 50 percent of the soil samples . contained less than 30 lb of nitrate N in the surface two feet. Only 35 percent of the 1,100 fields were given a nitrogen credit based on the residual nitrate test.... Download paper
3. Nitrate Test Clinics in Michigan Nitrate contamination of groundwater in Michigan is becoming an increasing public concern. Fertilizer N, animal manures and rural septic systems have been implicated as possible nonpoint sources of contamination. A state wide program of monitoring nitrate N in soil and well water was initiated. In the spring of 1989 and 1990, 74 nitrate testing clinics were conducted. Over 3,600 soil samples and 1,900 water samples were analyzed for nitrate N using the nitrate ion-specific electrode. More soil nitrate... Download paper
4. Study on Phosphorus and Nitrogen Concentration of Corn Adapted in South Dakota Though nitrogen (N) and phosphorus (P) are vital in several physiological and developmental processes in plants and animals, they pose several environmental, nutritional and health problems, if present in excess amounts. Reduction in the excess input of these nutrients into the soil, thereby reducing environmental problem and consequently nutritional and health problem, can be achieved by balancing their concentration in animal feed. Therefore, this research aims to quantify the nitrogen and phosphorus... Download paper
