Consistent use of high RSC water may deteriorate the physical properties of soil and increases pH and SAR of soil. Continuous use may reduce germination / the establishment of seedling, retards plant growth and leads to a significant reduction in yield. Therefore, a field experiment in microplots was displayed at research plot in St. John’s College, Agra to study the effect of sodic water on th...
sodic soil is one of the most common problems of limiting agricultural production that related on irrigation. saturated hydraulic conductivity is one of hydrodynamic characteristics in evaluating transmission flow through underground levels. to investigate the role of increment of exchangeable sodium in hydraulic conductivity changes (as characterized by the mobility of water in soil) an experi...
to find the nutritional condition of plants as related to the tatus of soil nutrients, also for an evaluation of soil solution toxicity and nutrition of plants in salt affected soils, it is preferred to study the activity of these elements rather than their concentrations. to calculate the ionic strength of a solution the concentrations of all cations and anions are needed which is very time co...
Bennett et al. [1] present the phylogenetic distribution of salt-tolerant species on a phylogeny of 2684 grasses in the context of plant breeding for salt-tolerance. Salt-tolerance, they conclude, is an evolutionary labile trait that has evolved a number of times across many lineages; this is at odds with the record of difficulty in breeding salt-tolerant crops. One potential explanation for th...
Soil-water flow velocity can be a major factor affecting ion movement in the soil matrix. The transport of both cations and anions and their interactions with soil surface affect many aspects of soil management such as wastewater disposal, saline soil reclamation, remediation of sodic soils, and soil decontamination (HENG et al., 1999a). Therefore it is important to understand the processes tha...
