With the precision provided by Veris® Technologies on-the-go soil sensors you can accurately
and intensively map soil variability – giving you the information you need to get the most out of your soils.
Maps define soil texture variability by measuring electrical conductivity of the soil. Clay particles conduct more current than silt and sand.
Maps are created by measuring soil’s reflectance at two wavelengths under the surface.
Readings are taken on-the-go providing 20-25 samples per hectare, required for a precise lime map.
“It was concluded that a grid spacing of 96 ft or less would be required to adequately assess the spatial variation of phosphorous and potassium and soil pH. Sampling at this intensity would require approximately 11 times as many soil samples as the commonly used 1/2 acre grid.”Lauzon, J.D., I.P. O’Halloran, D.J. Fallow, A.P. von Bertoldi & D.Aspinall
“Soil pH varied from 5.4 to 8.0 over distances of about 480 ft in most transects. In some sections, soil pH varied about 2 pH units over a 40 ft distance…”Biachini, A.A. and A.P. Mallarino
“Usually we would put 70 tonne of lime on a paddock that size. After the measurements were done we ended up only needing to put on 10 tonne of lime. It’s a significant difference and so much more accurate. It’s a saving by not having to apply so much lime but what we are really striving for is better crop yields and having the right pH level helps increase the outputs per hectare.”Guy Slater, Farmer
