Detailed measurements reject the practice of full width tillage with random traffic. There is a need to control traffic and open a drainage zone under the seeded plant in strip till or ridge till systems. We established agronomic use conditions for triadimefon, a fungicide, that will reduce the risk potential for contamination of surface and ground water. For instance, by using low rates of application in soils with typical organic matter and clay contents, triadimefon would have a low potential to leach through soil due to sorption on both the soil organic matter and clay. We now have an easy and useful technique to obtain data that are needed in pesticide transport models to better predict potential offsite movement of pesticides to surface and ground water.
Many soils are boron deficient for alfalfa growth.
Hence, this by-product of electricity generation can serve as a useful, environmentally benign, boron source for crop production. The theoretical basis for conductimetric measurement of ambient CO2 concentration was extended from absolute to differential measurement. The theory was tested and proven through the development of an accurate, inexpensive differential system. A system of measurements integrated with a specific knowledge of tillage and cover crop incorporation practices in bareroot tree nurseries can eliminate the need for field fumigation to control root disease. Unit research showed that in the worst-case scenario, a benign fumigant can replace methyl bromide, and yet produce a healthy transplant tree with practically no root disease.
