Variable indicators for optimum wavelength selection in diffuse reflectance spectroscopy of soils
Diffuse reflectance spectroscopy (DRS) operating in 350–2500 nm wave length range is fast emerging as a rapid and
non-invasive technique for analyzing multiple soil attributes. Because the spectral reflectance values in ...
How fertile are semi-arid tropical soils?
The semiarid
tropical (SAT) regions are notably characterized by low rainfall and high temperatures, and hence low natural primary
productivity and soil fertility. However, to adequately respond to the title of our article ...
Zeolitic soils of the Deccan basalt areas in India: their pedology and edaphology
Zeolites play an important role in modifying the chemis-try, physics and biology of soils. Here we review the status of the pedology and edaphology of the zeolitic soils of the Deccan basalt areas of India. Research has ...
Heavy metals concentration in soils under rainfed agro-ecosystems and their relationship with soil properties and management practices
Heavy metals are governed by parent material
of soils and influenced by the soil physicochemical properties
and soil and crop management practices. This paper
evaluates total heavy metal concentrations in rainfed soils
under ...
Comparison of data mining approaches for estimating soil nutrient contents using diffuse reflectance spectroscopy
Diffuse reflectance spectroscopy (DRS) operating in wavelength range of 350–2500 nm is emerging as a rapid and noninvasive
approach for estimating soil nutrient content. The success of the DRS approach relies on the ability ...
Comparative Evaluation of Inductively Coupled Plasma–Atomic Emission Spectroscopy and Colorimetric Methods for Determining Hot-Water-Extractable Boron in Soils
Boron (B) deficiency frequency is increasing in rainfed systems and hence the need to diagnose the deficiency. Colorimetric methods are still widely used in soil testing laboratories in India for measuring B. Little ...
Soil and water management
Soil and water form the basis of all terrestrial life. Their resources vary widely and are affected by natural and anthropogenic
perturbations. Ancient civilizations and cultures emerged and sustained on good soils; and ...
Carbon Sequestration in Indian Soils: Present Status and the Potential
India’s growing self-sufficiency in food production
and food stocks since independence suggest that
soils have the capacity to produce. Therefore, a review of
Indian soils and their capacity to sequester carbon; and ...
Pasture degradation effects on soil quality indicators at different hillslope positions in a semiarid region of western Iran
A study was made to determine the influence of
pasture degradation on soil quality indicators that included
physical, chemical, biological and micromorphological
attributes, along the hillslope positions in Chaharmahal ...
Soil information system: web-based solution for agricultural land-use planning
The soil-forming factors, especially climate, vegetation
and topography, act on a range of rock formations
and parent materials leading to the development of
different kinds of soils. Through concerted efforts, soil
datasets ...
