Comparison of soil pH measurement in a non tilled vineyard: conventional laboratory values vs. 3100 Veris soil pH sensor readings

Abstract

This work pretends to compare the soil pH measured by the 3100 Veris sensor with the conventional soil sampling in a specific soil condition of a non tilled vineyard. Whereas high density data was obtained with the soil pH sensor, which were used to delineate a pH surface using a geostatistical algorithm, conventional laboratory values were divided in two sets, depending on their location in a 3 or a 12 years non tilled vineyards. Comparison leads to some differences, but varibility was minor when the area not mobilized for 12 years was considered.
