Veris pH and EC Maps
By using the Veris machine sensor, we are able to quickly map 1' and 3' EC (soil texture) and pH maps. Having maps like this are vital to ensuring organic matter makes it to lighter soil areas, and correcting the problem pH spots while leaving the good ones good.
The value of this mapping will vary according to crop value and input costs, the degree of variability within each field, the number of years the map will be used, and other factors. It’s important to consider the errors inherent in less expensive maps. Research has shown that pH sensor maps improve lime application precision by an average of 1100 lbs/ac (1233 kg/ha) versus 2.5 ac (1 ha) grid sampling. Multiplying that by local lime applied cost calculates the value of that layer. Comparing OM and CEC maps from Veris sensors versus soil surveys reveals significant inclusions and errors in the old surveys. Applying several thousand corn seeds/acre above or below what your soil can sustain, could cost you hundreds, even thousands of dollars per field--every year you plant it to corn.
