Effects of nitrogen on growth, and nitrogen and phosphorus uptake in tops and roots of sorghum grown in an alfisol and a vertisol...conducted to study the effects of added nitrogen (0, 10, 25, 50 and 100 mg N kg–1 soil) on dry matter production, and N and P uptake in tops and roots of sorghum (cv CSH6) grown in a Vertisol and an Alfisol for 42 days at field capacity soil moisture content....
Sorption of labelled phosphate by a vertisol and an alfisol of the semi-arid zone of indiaAdsorption isotherms for total adsorbed phosphate and isotopically exchangeable phosphate were measured for typical examples of a Vertisol and an Alfisol, occurring in close proximity at the ICRISAT centre....
Relationship between extracted phosphorus and sorghum yield in a vertisol and an alfisol under rainfed croppingField experiments were conducted during the 1990 rainy season (June-September) in Andhra Pradesh, India on Vertisol and Alfisol sites having a range in extractable P, for establishing relationships between extractable P and sorghum yield....
Physico-chemistry and mineralogy related to productivity of arenosol, luvisol and vertisol*... In this qualitative study, interactions between mineralogy and physico-chemistry and their role on the productivity of two luvisols, an arenosol and a vertisol are investigated....
