Harnessing productivity potential and rehabilitation of degraded sodic lands through Jatropha based intercropping systems
2016
Abstract This paper evaluates an intercropping model with J atropha curcas L. (JCL) as an alternative crop on degraded sodic land in north India. Monoculture of JCL has not proven economically viable in India in view of its poor yield; therefore, intercrops in between JCL plantations were tried to optimize land use efficiency. The results revealed that the planting of JCL at 3 × 3 m spacing with inter-cultivation of sweet basil–matricaria (SB-M) cropping system for four years was more economically viable than planting at 3 × 2 m spacing and the other rotations tested in the study. Improvements in soil properties in terms of soil pH, EC and organic carbon were found with the SB-M cropping sy…
Cárcavas y regueros generados en suelos sódicos : Petrer (Alicante, España)
2013
Este articulo pretende mostrar las interacciones entre los procesos de piping y la formacion de carcavas y regueros en diferentes sub-sistemas (laderas y rellenos de fondo de valle) de una pequena cuenca del SE espanol. Se analiza la influencia de diversas propiedades del los suelos y regolitos en el desarrollo de formas asociadas al piping. Los sistemas reguero-tunel de las laderas de badlands estan principalmente relacionados con la ratio de absorcion de sodio (SAR) y la conductividad electrica (CE) de los suelos. En contraste, en los rellenos de fondo de valle estas propiedades quimicas interactuan con las discontinuidades en el gradiente hidraulico introducidas por las terrazas de culti…
Field and laboratory approaches for determining sodicity effects on saturated soil hydraulic conductivity
2006
Abstract Dilution of high-sodicity soil water by low-sodicity rainfall or irrigation water can cause declining soil hydraulic conductivity (K) by inducing swelling, aggregate slaking and clay particle dispersion. Investigations of sodicity-induced reduction in K are generally restricted to repacked laboratory cores of air-dried and sieved soil that are saturated and equilibrated with sodic solution before tests are conducted. This approach may not yield a complete picture of sodicity effects in the field, however, because of loss of antecedent soil structure, small sample size, detachment of the sample from the soil profile, reliance on chemical equilibrium, and differing time scales betwee…
