Varieties of management such as fertilizer application, crop chosen, or pesticide and herbicide application, can cause large varieties in soil quality. Testing the Electronic Conductivity, pH and LOI on soil samples helps to access the variability of the soil quality in bioenergy crop fields on the Arkansas State University Farm Complex. The fields are divided into four blocks that have twenty 90'*24' plots in each. The 80 0-10cm soil samples are taken by random 4'*4' grids, and had been air dried and ground before testing. The result, for example, from block one shows that average EC is 80 mS/m, the pH is in the range of 6.31-6.90, and the average soil O.M. is 3.20%, which means the soil has good quality, and has been well maintained for growing bioenergy crops.
