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 ...
Diffuse Reflectance Spectroscopic Approach for the Characterization of Soil Aggregate Size Distribution
Assessment of soil structure and soil aggregation remains a challenging task.
Routine methods such as dry- and wet-sieving approaches are generally time
consuming and tedious, which calls for a robust, fast, and ...
Red ferruginous soils of tropical Indian environments: A review of the pedogenic processes and its implications for edaphology
Red ferruginous (RF) soils of tropical Indian environments belong to Entisols, Inceptisols, Alfisols, Mollisols and
Ultisols soil orders. The occurrence of Ultisols alongside acidic Alfisols and Mollisols in both zeolitic ...
Comparative evaluation of protein content in groundnut samples by near infrared reflectance spectroscopy and Skalar colorimetric methods
A lot of research has been done in developing groundnut cultivars with highquality
oil. As a result, methods for routinely determining oil
content and quality have been developed and utilized. However, groundnut is also a ...
Soil test-based nutrient balancing improved crop productivity and rural livelihoods: case study from rainfed semi-arid tropics in Andhra Pradesh, India
Widespread multinutrient deficiencies in the semi-arid tropics (SAT) are among major factors for large gaps between farmers’ current crop yields and potential yields. In this study, we adopted stratified soil sampling ...
Plant prebiotics and human health: Biotechnology to breed prebiotic-rich nutritious food crops
Microbiota in the gut play essential roles in human health. Prebiotics are non-digestible complex carbohydrates
that are fermented in the colon, yielding energy and short chain fatty acids, and selectively promote the ...
CALIBRATING CHLOROPHYLL METER (SPAD-502) READING BY SPECIFIC LEAF AREA FOR ESTIMATING LEAF NITROGEN CONCENTRATION IN SWEET SORGHUM
The chlorophyll meter (SPAD-502) is used to estimate nitrogen status of various crops. However,
the relationship between SPAD readings and leaf nitrogen concentration (LNC) in sweet sorghum
(Sorghum bicolor) has not been ...
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 Testing as a Tool for On-Farm Fertility Management: Experience from the Semi-arid Zone of India
Rainfed agriculture in the dry regions is affected by water shortages. Our earlier
research showed that the deficiencies not only of major nutrients but also those of sulfur
(S) and micronutrients are holding back the ...
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 ...
