This review addresses the applicability of visible (Vis), near-infrared (NIR), and mid-infrared
(MIR) reflectance spectroscopy for the prediction of soil properties. We address (1) the …

There are tens of millions of contaminated soil sites in the world, and with an increasing
population and associated risk there is a growing pressure to remediate them. A barrier to …

Since both the spatial and vertical heterogeneities in soil properties have an impact on crop
growth and yield, accurate characterization of soil properties at high sampling resolution is a …

In the modern era, due to the rapid increase in urbanization and industrialization in the
vicinity of the Himalayas, heavy metals contamination in soil has become a key priority for …

Total X-ray fluorescence spectroscopy (TXRF) determines concentrations of major and trace
elements in multiple media. We developed and tested a method for the use of TXRF for …

Soil spectroscopy can provide low-cost and high-density data for predicting various soil
properties. However, a relatively weak correlation between the spectra and the …

There are currently many in-field methods for estimating soil properties (eg, pH, texture, total
C, total N) available in precision agriculture, but each have their own level of suitability and …

Soils are notoriously spatially heterogeneous and many soil properties are temporally
variable. Spatial variability of soil properties has a profound influence on agricultural and …

The purpose of this paper was to study the spatial characteristics and possible influencing
factors of farmland soil texture and salt content in the Syr Darya River Basin. Data on the soil …

Core Ideas Infrared spectroscopy and chemometrics can be used to quantify soil labile C.
Soils amended with organic materials need to be taken into account during calibration …
