Soil moisture (SM) is a key hydrologic state variable that is of significant importance for
numerous Earth and environmental science applications that directly impact the global …

This article reviews the current research and applications of various digital soil mapping
(DSM) techniques used to map Soil Organic Carbon (SOC) concentration and stocks …

Electromagnetic induction (EMI) has been used to characterize the spatial variability of soil
properties since the late 1970s. Initially used to assess soil salinity, the use of EMI in soil …

There is a global demand for soil data and information for food security and global
environmental management. There is also great interest in recognizing the soil system as a …

Mapping and monitoring soil spatial variability is particularly problematic for temporally and
spatially dynamic properties such as soil salinity. The tools necessary to address this classic …

Salt related problems in soils can refer to an excess of soluble salts (saline soils), a
dominance of exchangeable sodium in the soil exchange complex (sodic soils), or a mixture …

Cation exchange capacity (CEC, cmol (+) kg− 1) is a measure of the capacity of soil to retain
and exchange cations. However, it is expensive to sample and directly measure across a …

Site-specific seeding (SSS) is a precision agricultural (PA) practice aiming at optimizing
seeding rate and depth, depending on the within field variability in soil fertility and yield …

Relationships between parent material and soil are not well understood and generally only
reported in qualitative form. We present a classification of parent material for pedologic …

Abstract Knowledge of the soil water balance is fundamental for improving crop water use in
agricultural fields. Estimates are normally for representative and homogeneous areas where …
