Bui's commentary [1] arises from an observation made in our paper on the evolution of salt tolerance in grasses. We described the 'paradox' of salt tolerance ; that it evolves often in nature but is hard to breed into crops [2], although there has been recent success in increasing the tolerance of wheat on salt-affected soils in Australia [3]. Bui suggests that one reason for lack of success in...
Introduction: Saline soil contains large amounts of soluble salts. In addition to natural factors affecting soil salinization such as climate, topography, and abundance of evaporative formations in the region, the human factors that result from incorrect management of the agricultural system (such as using low-quality water for irrigation, overuse of chemical fertilizers, the frequency of irrig...
Introduction: Kimura’s disease (KD) is an allergic inflammatory disorder of unknown etiology endemic in Orientals. Kimura’s disease was first mentioned by Kimm and Szeto in China in 1937. Kimura’s disease is commonly encountered in Asia and is mostly reported in Japan, China, Singapore and Honkong. However, only a few cases have been reported in the Indian subcontinent. Case Report: A case of K...
Inorganic carbonate in soil occurs predominantly as the sparingly soluble alkaline-earth carbonates, calcite (CaCOs) and dolomite (CaMg(CO,),). Calcite is usually the dominant form in active pedogenic environments (Doner & Lynn, 1977; Nelson, 1982). There are only a few reported occurrences of aragonite (CaCOs) and vaterite (CaCOs) in soils. Sodium carbonate and magnesium carbonate and hydroxyc...
A field experiment on a saline-sodic soil with pH 8.21-8.42, ECe 6.40-7.90 dSm and SAR 17.79-23.46mmolwas carried out using five soil reclaiming treatments viz., leaching (Control), Farm yard manure (FYM) @ 10 tons ha, Rice Husk (RH) @ 10 tons ha, FYM+RH @ 5+5 tons ha and Gypsum @ 100% soil requirement in a complete randomized block design with four replications. Rice variety SARSHAR and wheat ...
