Soil Health Benefits For Your Cropping System
Presented by Robby Bevis
Arkansas Farmer: Soybeans, Cotton, Corn, Rice
Presented by Keith Scoggins
Soil Specialist,University of Arkansas Cooperative Extension Service
Let me guess, you like the idea of cover crops and no till, but will it work in your cropping system. This is the southeast US it is subject to rain 5" any given fall, is it possible to be in a no till cropping system with that kind of volatile weather. Absolutely, there are farmers all over the mid-south who are building their soils to be more resilient making it easier to overcome challenges. Robbie Bevis and Keith Scoggins are two young farmers who are doing it, in soybeans, corn, and yes even RICE.

The Effect Of Soil Sampling Approach And Interpolation Method In Developing Potassium Prescription Maps
Presented by Dr. Leo Espinoza
Soil Specialist,University of Arkansas Cooperative Extension Service
There is a need to develop an understanding of which soil factors and management practices have a larger effect on the variability of a nutrient in a field. Successful variable rate fertilization requires an accurate description of the variability of the nutrients of interest. The objective of this presentation is to share preliminary results of a project aimed to evaluate the spatial dependence of potassium in several fields in Arkansas, and which soil sampling method and interpolation technique best describe its spatial variability in a field.

Precision Irrigation: Many Tools Are Available To Improve Water Application
Presented by Dr. Daniel K. Fisher
Research Agricultural Engineer, US Department of Agriculture, Agricultural Research Service
Changes in crops, varieties, weather patterns, cultural practices, and water resources necessitate changes in irrigation practices. Addressing water requirements to improve yield and quality, reducing time and labor needed to perform field operations, and improving water application and conservation efforts can be accomplished through advances in irrigation technologies. Many tools are available, including automated sensors, computer software, scheduling methods, surge-flow valves, and flowmeters, that can help producers make better-informed irrigation decisions and more precisely apply valuable water resources. Various irrigation technologies will be presented and discussed to see how these tools can be incorporated to more precisely deal with irrigation and conservation activities.

Mapping Soil And Plant Variability Of Soybean Fields With On-The-Go Sensors And Free And Open-Source Software
Presented by Dr. Reginald S. Fletcher
Research Agronomist, USDA-ARS
On-the-go sensors are available that can measure various soil and plant properties. Free and open-source software provides an inexpensive means for processing data. The following topics will be discussed in detail for soybean production systems: (1) measuring soil electrical conductivity, soil reflectance, plant height, and plant yield with on-the-go soil and plant sensors, (2) using free and open-source software to create maps showing within field variability of soil and plant variables, (3) evaluating the relationships between soil and plant variables measured with on-the-go systems, and (4) developing management zones.
