Publisher Summary Soil genesis in the Alfisol profile has achieved a stage of prominent expression with the development of the argillic horizon. If the Entisol order could be considered the stage of minimum organization, the Alfisol (and possibly the Ultisol profile) is a stage of maximum organization of the soil fabric.

Alfisols and closely related soils in China
Chinese Geographical Science, 1992Alfisols are important soils in China. They occupy about 1.25 million km2, or about 13% of the land area. In the current Chinese system of soil classification, burozem, yellow-brown earths, Baijiang (Planosol) soils and parts of drab soils. They are mostly forested soils with an estimated 5–13 t/ha · yr of organic matter returned to the soils from ...

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.

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

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 ...

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 ...
