Visible and near-infrared (Vis-NIR) spectroscopy is a cost-effective technique for alternative
soil physical and chemical analyses for estimating soil properties. The optimal band …

The conventional methods for measuring soil properties are time-consuming and expensive.
Over the past few decades, reflectance spectroscopy has been widely applied as a rapid …

Quantifying the organic carbon content of soil over large areas is essential for characterising
the soil and the effects of its management. However, analytical methods can be laborious …

Cation exchange capacity is a crucial metric for managing soil fertility and promoting
agricultural sustainability. An alternative technique for the non-destructive assessment of …

In recent years, the pocket penetrometer (PPT) test has been used to measure soil
compaction and has gained attention due to its simplicity, high speed, and low cost. This …

Whether spectral feature parameters (SFPs) can be effectively used to predict soil organic
matter (SOM), and its spatial transferability was tested for different regions. In this study, a …

The aim of this study was to evaluate whether Na-and Ca-montmorillonite and the swell-
indicating properties (ie, free swell index, water uptake capacity, and cation exchange …

Heavy metal contamination in urban land has become a serious environmental problem in
large cities. Visible and near-infrared spectroscopy (vis-NIR) has emerged as a promising …

Reflectance spectroscopy as an efficient proximal sensing method, can be employed in soil
genesis, monitoring, and management studies. However, limited data about the …

The present study aimed to determine the best performance of polymeric materials (RPP
and CBR Plus) in various types of fine-grained soil, and the optimal percentage of polymeric …
