Improving Soil Physical Indicators by Soil Amendment to a Saline-Sodic Soil
The application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. In this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. The five treatments were control (withoutamendment), municipal solid waste compost (MC), vermicompost...
متن کاملBiomass accumulation and potential nutritive value of some forages irrigated with saline-sodic drainage water
A controlled study using a sand-tank system was conducted to evaluate 10 forage species (bermudagrass, ‘Salado’ and ‘SW 9720’ alfalfa, ‘Duncan’ and ‘Polo’ Paspalum, ‘big’ and ‘narrow leaf’ trefoil, kikuyugrass, Jose tall wheatgrass, and alkali sacaton). Forages were irrigated with sodium-sulfate dominated synthetic drainage waters with an electrical conductivity of either 15 or 25 dS/m. Forage ...
متن کاملResidual alkalinity as tracer to estimate the changes induced by forage cultivation in a non-saline irrigated sodic soil
Soil alkalinisation generally constitutes a major threat to irrigated agriculture in the semiarid regions of West Africa. The improvement of sodic soils is generally difficult and expensive. However, a recent study in the Niger valley in NIGER, reveals that a natural dealkalinisation is possible under natural conditions in a semi-arid climate. Transformation of non-saline sodic soil into brown ...
متن کاملSaline/Sodic sub-soil on triticale, durum wheat and bread wheat yield under irrigated conditions
Sub-soil (> 30 cm) salinity and sodicity is a growing problem particularly in irrigated agricultural areas with rising water tables, poor water quality and/or deficient soil drainage. There were two objectives in this study; (1) to quantify the effect of sub-soil salinity and sodicity in grain yield of triticale, bread wheat and durum wheat and, (2) to determine if genotypes within and between ...
متن کاملStability of a Calcareous Saline-Sodic Soil During Reclamation
General guidelines to reclaim saline or sodic soils do not adequately consider variables such as pH and the presence of organic matter that are known to affect soil stability. Poor structural stability of sodic, saline-sodic, and high-pH soils adversely influences crop yields; promotes piping, tunneling, and slope erosion; and can accelerate the failure of water conveyance systems. We evaluated...
