“…These results suggest that combined amendments were superior to either one alone in their effect on increased maize yield. Although gypsum has been reported extensively to improve cereal yields (Oster, 1982;Swarup, 1994;Wahid et al, 1998;Hanay et al, 2004), in our study, it was found to be more effective when combined with FYM. It is possible that the observed changes in physical and chemical soil properties due to addition of FYM and gypsum (Tables 1 and 2) were responsible for increased maize yields.…”

“…Studies on salt-affected soils have been carried out in different parts of the world in a range of crops using different techniques (Oster, 1982;Swarup, 1994;Hyas et al, 1997;Wahid et al, 1998;Madejon et al, 2001;Sharma et al, 2001;Sahin et al, 2002;Hanay et al, 2004;Sharma and Minhas, 2004). However, few studies, if any, have assessed such techniques in Tanzania.…”

“…Gypsum is the most promising and effective amendment for sodic soil reclamation because of its availability, low-priced and ease of handling (Amezketa et al, 2005, Abd El-Hady andShaaban 2010). Gypsum is relatively insoluble and it has lowest solubility in water below 40ºC (Azimi et al, 2007), whereas CaCl 2 is more soluble in water than gypsum (Oster, 1982). Both chemicals are similarly with calcareous soil (Shainberg et al, 1982).…”

“…Moreover owing to its accessibility, low-priced and ease of handling (Amezketa et al, 2005) it is extensively practiced as reclament to counteract the injurious effects of high sodium leading to considerable decrease in electrical conductivity and sodium adsorption ratio of soil (Hamza and Anderson, 2003). However, gypsum is relatively insoluble and below 40ºC it has lowest solubility (Azimi et al, 2007) in water, whereas CaCl 2 is more soluble in water than gypsum (Oster, 1982) and both the chemical behave similarly in calcareous soil (Shainberg et al, 1982). Likewise, recently considerable research has been undertaken, which elucidate that use of organic matter is also an efficient approach for remediation of salt-affected soils (Pang et al, 2010).…”

ABSTRACT. Amelioration of salt-affected soils requires an integrated management approach, which not only improves their effectiveness for improving soil properties, but also increases the crop production and quality of the produce. Hence, a study was planned to evaluate combined use of organic and inorganic amendments for better rehabilitation of salt affected soil in ricewheat cropping sequence from 2013 to 2016. Treatments included T 1 -control, T 2 -gypsum @ 100 SGR, T 3 -CaCl 2 @ 50% SGR, T 4 -CaCl 2 @ 50% SGR + biogas slurry @ 10 tˑha for wheat (Inqlab-91) and 110-90-60 NPK kg ha -1 for rice (Shaheen Basmati) was applied. Soil samples were collected before application of amendment and after harvesting of each crop. Straw and grain/paddy yield data were recorded at maturity. Pooled data showed that grain/paddy and straw yield of wheat and rice crop was higher in T 2 (gypsum @ 100% SGR), but statistically (P≤ 0.05) non significant with T 4 (CaCl 2 @ 50% SGR + biogas slurry @ 10 tˑha -1 ). T 3 (CaCl 2 @ 50 % SGR) was at par with T 6 (H 2 SO 4 @ 25% SGR + biogas slurry @ 10 tˑha -1 ), followed by T 5 (H 2 SO 4 @ 25% SGR). The minimum yield was recorded in T 1 (control). Soil analysis showed that pH s , EC e and SAR were significantly decreased in T 2, (Gypsum @ 100% SGR), followed by T 4 (CaCl 2

“…This can be accomplished by applying calcium to the soil, the amount based on the extent of exchangeable magnesium to be replaced. This amelioration strategy is similar to sodic soils where calcium supply mitigates the deleterious effects of sodium (Oster, 1982). While different sources of calcium have been used as a soil amendment in research and practice, gypsum (CaSO 4 •2H 2 O) is the most commonly-used amendment because of its low cost.…”

Resource Recovery and Reuse (RRR) is a sub-program of the CGIAR ResearchProgram on Water, Land and Ecosystems (WLE) dedicated to applied research on the safe recovery of water, nutrients and energy from domestic and agro-industrial waste streams. This SRP aims to create impact through different lines of action research, including (i) developing and testing scalable RRR business models, (ii) assessing and mitigating risks from RRR for public health and the environment, (iii) supporting public and private entities with innovative approaches for the safe reuse of wastewater and organic waste, and (iv) improving rural-urban linkages and resource allocations while minimizing the negative urban footprint on the peri-urban environment. This sub-program works closely with the World Health Organization (WHO), Food and Agriculture Organization of the United Nations (FAO), United Nations Environment Programme (UNEP), United Nations University (UNU), and many national and international partners across the globe. The RRR series of documents present summaries and reviews of the sub-program's research and resulting application guidelines, targeting development experts and others in the research for development continuum. He is a water and soil management scientist with a focus on developing countries, and interests in water recycling and the safe and productive use of wastewater, water quality and environmental health, and amelioration of salt-induced land degradation. He has implemented multi-disciplinary projects and directed research teams in Central and West Asia, and North Africa. Manzoor has more than 100 peerreviewed publications to his credit. He serves on the editorial boards of four international journals. Science with a human face
