INVESTIGATION ON STRUCTURAL INDICES OF ALFISOL AND ENTISOL SOILS
Madras Agricultural Journal, 1988Structural indices of Alfisol (Red) and Entisol (Alluvial) soil profiles studied are re- ported in this paper. The stability index, aggregate stability, structural coefficient and aggregation index are considered to be reliable structural indices and accordingly the structure of Red and Alluvial soils could be considered as moderately developed. It was

Electrochemical Properties of Some Oxisols and Alfisols of the Tropics
Soil Science Society of America Journal, 1972Abstract A study of the distribution of the electric charges in the Ap and B2 horizons of two highly weathered Oxisols and one Alfisol from Brazil was made by means of potentiometric titration and by direct measurement of adsorption of ions in the presence of varying concentration of electrolyte.

DRIS NUTRIENT NORMS FOR PINEAPPLE ON ALFISOLS OF INDIA
Journal of Plant Nutrition, 2010Sub-optimum production in pineapple fields in India is a common feature in Alfisols. The diagnosis and management of nutrient constraints assume a greater significance in maximizing production sustainability. DRIS norms were computed from the data bank of 324 sub-plots on leaf mineral composition, soil available nutrients, and corresponding mean yield ...

INFLUENCE OF ELECTROLYTE ON CADMIUM INTERACTION WITH SELECTED ANDISOLS AND ALFISOLS
Soil Science, 1997The adsorption-desorption of cadmium (Cd) as a function of pH, ionic strength, and composition of the electrolyte was examined for four variable charge soils: two Alfisols from Zimbabwe (Mazowe and Bulawayo) and two Andisols from Spain (Realejos=l and Realejos=2).

Land use options on a semi-arid Alfisol
American Journal of Alternative Agriculture, 1993AbstractFour land use options—annual cropping, agroforestry, agrihorticulture, and agrosilviculture—were tried on a Land Capability Class IVs Alfisol under rainfed conditions to find a farming system that would be profitable and sustainable. The agrihorticultural system required more cash input but gave a value/cost ratio of 2.16 compared with 1.95 ...

Sustainable Management of Dryland Alfisols (Red Soils) in South India
Journal of Crop Improvement, 2009A community based cooperative research project was implemented on farmers' fields on some dryland Alfisols in Tamil Nadu, India, to demonstrate and validate improved dry-farming technologies, such as: 1) soil and water conservation and water harvesting; 2) cropping systems, including intercropping and double cropping; 3) recycling of processed ...

Structure and variation of root-associated microbiomes of potato grown in alfisol
World Journal of Microbiology and Biotechnology, 2019Root-associated fungi and bacteria play a pivotal role in the plant-soil ecosystem by influencing both plant growth and immunity. The aim of this study was to unravel the biodiversity of the bacterial and fungal rhizosphere (RS) and rhizoplane (RP) microbiota of Zhukovskij rannij potato (Solanum tuberosum L.) cultivar growing in the Alfisol of ...

Moisture Retention of Cultivated and Pastured Mollisols and Alfisols
Soil Science Society of America Journal, 1971Abstract Comparison of surface soil moisture characteristic curves for Mollisols and Alfisols under pasture and row‐crop cultivation revealed that below ⅓ bar suctions cultivated Mollisols retained 40% more water and cultivated Alfisols retained 25% more than corresponding pastured soils.
