In Arkansas, very few farmers are using any kind of precision farming activities and these activities are mostly confined to in-field variability data collection. This study has been undertaken to collect and analyze these spatial data for any useful information it may contain. Soil fertility and electrical conductivity measured a with VERIS equipment were analyzed with respect to spatial yield. The analysis showed strong correlation between VERIS data and soil fertility measures such as phosphorus, calcium, magnesium, CEC, pH, organic matter, boron, and sulfur. Many of these fertility factors were also significantly correlated to crop yield. No single factor was consistently predominant in the two study fields for the three years of study. Analysis of data based on a buffer area of 10 m radius at a 100 m grid in field 7 showed strong correlation in 2001 (above 0.6) and 1999 (above 0.4) and relative low correlation of 0.21 and 0.25 in 1998, between VERIS data and yield. Field 66N did not exhibit a significant correlation between yield and VERIS data. Correlation analysis at 15×20 m grid showed poor correlation between yield and VERIS data in 1999 and 2001 and a strong correlation in 1998. These contradictory results at two different resolutions show that data resolution is very important for obtaining reliable results and for making reasonable management decisions. Soil grid data at a higher resolution need to be analyzed to obtain the actual trends between fertility factors and yield as well as soil fertility factors and VERIS.
