Biography :
Jorge A. Delgado is an Acting Research Leader with USDA-ARS and a Fellow of the ASA, SSSA, and SWCS. Dr. Delgado received his B.S. degree from the University of Puerto Rico, and his M.S. and Ph.D. from Louisiana State University. He has been Research Editor of the Journal of Soil and Water Conservation since 2001. He is a national/international leader in the field of nitrogen management and an expert in developing new concepts and applying software tools and cover crops for soil and water conservation, increasing farm-level nitrogen use efficiencies. He has published 200+ publications.

4 Rs Are Not Enough

4 Rs Are Not Enough: We Need 7 Rs for Nutrient Management and Soil and Water Conservation

The concept of precision farming has been around for about the last two decades and big steps forward have been achieved. The 4Rs concept is viewed as the method to increase nutrient use efficiency while reducing nutrient losses and impacts to the environment. This presentation aims to bring to the forefront the need to incorporate precision conservation to improve nutrient management, reduce off-site transport of nutrients, and minimize off-site impacts. This presentation covers the Delgado (2015) publication that proposes that the 4Rs (right product, at the right rate, at the right time, and at the right place) are not enough to reduce environmental impacts. There is a need to bring precision conservation to the forefront of precision farming and use 7 Rs (right product, right rate, right method, right practice, right place, right scale, and right time) for nutrient management and soil and water conservation. Nutrient management and conservation need to go together in the same plan.

Biography :
Jason Warren currently serves on the faculty of Oklahoma State University as an assistant professor, and soil and water conservation/management extension specialist. Jason grew up on a small grain and cattle farm in Woods Co. OK. He earned a B.S. degree in Environmental Sciences in 1999 and M.S. in Plant and Soil Sciences in 2001 at Oklahoma State University. Jason continued his education at Virginia Tech, where he obtained a Ph.D. in Crop and Soil Environmental Sciences in 2005 and then spent two years as a Post Doctoral Research Soil Scientist at the USDA-ARS Animal Waste Management Research Unit in Bowling Green, KY. Dr. Warrenâ™s research and extension efforts will focus on management practices to reduce soil erosion and improve soil quality in both the agricultural and urban andscapes. He will also be engaged in activities aimed at increasing water use efficiency and reducing the transport of contaminates to surface and subsurface waters.

Adapting Precision Technologies to the Management of Soil Health

This presentation will provide a framework for soil health assessment as well as a discussion of temporal and spatial variability in soil health characteristics. This will be followed by a discussion about precision management may be applied to improve the effciency of management options to improve soil health.
