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 ...
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 ...
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 ...
Cultivation of sweet sorghum on heavy metal contaminated soils by phytoremediation approach for production of bioethanol
The term heavy metal (HM) has a wide range of meanings, and there has been no consistent definition by any authoritative body such
as International Union of Pure and Applied Chemistry (IUPAC) over the past 60 years. But ...
Quality Control in Soil Testing Using the Internal Standards: Temporal Variability in Organic Carbon and Extractable Nutrient Elements
Internal soil standards are used in an analytical laboratory as one of the tools for providing feedback on the quality of soil testing service provided. The objective of this study is to provide results on the temporal ...
Soil information system: use and potentials in humid and semi-arid tropics
The articles presented in this special section emanated from the researches of consortium members of the National Agricultural
Innovative Project (NAIP, Component 4) of the Indian Council of Agricultural Research (ICAR), ...
