Soil pH Mapping with an On-The-Go Sensor
Soil pH is a key parameter for crop productivity, therefore, its spatial variation should be adequately addressed to improve precision management decisions. Recently, the Veris pH Manager™, a sensor for high-resolution mapping of soil pH at the field scale, has been made commercially available in the US. While driving over the field, soil pH is measured on-the-go directly within the soil by ion...
متن کاملDevelopment of soil pH and lime requirement maps using on-the-go soil sensors
Since conventional sampling and laboratory soil analysis do not provide a cost effective capability to obtain georeferenced measurements with adequate frequency, different onthe-go sensing techniques have been attempted. One such recently commercialized sensing system combines mapping of soil electrical conductivity and pH. The concept of direct measurement of soil pH has allowed for a substant...
متن کاملDesign and Validation of an On-the-go Soil Strength Profile Sensor
Soil strength has traditionally been determined using the cone penetrometer, an instrument that provides highly variable discrete point measurements, making it difficult to detect statistically significant differences in the soil strength profile among treatments or locations. Generally, this problem has been addressed by obtaining a large number of measurements, a process that is time-consumin...
متن کاملUsing an Automatic Resistivity Profiler Soil Sensor On-The-Go in Precision Viticulture
Spatial information on vineyard soil properties can be useful in precision viticulture. In this paper a combination of high resolution soil spatial information of soil electrical resistivity (ER) and ancillary topographic attributes, such as elevation and slope, were integrated to assess the spatial variability patterns of vegetative growth and yield of a commercial vineyard (Vitis vinifera L. ...
متن کاملSoil calcium and pH monitoring sensor system.
An agrarian sensorial system based on temperature, moisture, and all solid-state ion-selective potentiometric sensors was developed with the objective of monitoring the behavior of H+ and Ca2+ ions in soil and in real conditions, contributing with a new tool that tries to complement the current precision agriculture technology. The evaluation of the sensorial system to pH monitoring presented a...
