Last week the AZAG newsletter featured a short publication on Sampling Soil for Root Knot Nematode in Cotton. One aspect of RKN incidence is that its distribution is associated with the higher percentage of sand in the sandy or sandy loam soils. Veris survey is a technique that can quantify the variability in the soil texture. The technique is based on measuring the electric conductivity in the soil that can give direct relationship to the soil texture. Data obtained from Veris survey can be used to develop a soil texture map of the field that shows color coded areas with higher percentage of sand. This map can precisely target sampling sandy areas where RKN is more likely to occur. It can also help direct nematicide applications to manage RKN in these sandy areas in the field. For more information on Veris soil mapping system and directed soil sampling click here for this short video.
