“…Gypsum consider is an organic soil amendment or nutrition as a source of Ca and S, changes structure and fertility of heavy clay soils, improves soil infiltration and drainage, decreases acidity and eliminate sodium-affected soils by removing sodium form the soil and replacing it with calcium (Korcak,1993;Chen and Dick, 2011). Various studies on the effect of gypsum application on saline-sodic soil have been showed that, gypsum removes the greatest amount of Na + from the soil and causes a substantial decrease in soil pH, electrical conductivity (EC) and exchangeable sodium percentage (Qadir et al 1996;Makoi and Verplancke, 2010;Cucci et al 2012 andNegim, 2015). It has been reported that gypsum addition to salinity stressed of some plants increased plant height, stem diameter, number of leaves, leaf area, root length and fresh and dry weight of the aboveground parts and roots as well as increased total chlorophylls, carbohydrates and NPK contents, while caused a reduction in the accumulation of Na + and Cl -toxic ions in plant tissues (Picchioni et al 2004;Mazhar et al 2011;Habba et al 2013 andAbdel Fattah et al 2014) Recently, use of Nanoparticles (NPs) has been broadly exploited in the agricultural system throughout the world.…”

An open field experiment was carried out during 2015 and 2016 seasons at the experimental nursery of the Ornamental Horticulture Department, Faculty of Agriculture, Cairo University, Egypt. The purpose of present research was to investigate the effect of foliar application of nano silicon with different concentrations and gypsum soil application on growth, flowering and chemical constituents of Jatropha integerrima plants irrigated with different levels of saline water. The concentrations of saline water were (1000, 2000 and 4000 ppm), in addition to tap water (270 ppm) as a control, simultaneously plants were received monthly foliar application of nano silicon 1 and 2 mM or soil application of gypsum at 20 g/plant, either applied individually or in combination.The results showed that, elevating salt concentration in irrigation water decreased vegetative growth characteristics, flowering traits, leaves anatomy and chemical constituents. In contrast, increasing salinity of irrigation water boosted contents of proline, Ca%, Na%, Cl%, total phenolic and flavonoids. On the other hand, foliar application of nano silicon and soil addition of gypsum treatments either individually or in combination had favorable effects on enhancing vegetative parameters and chemical constitutes, meanwhile decreasing accumulation of Na%, ISSN 2166-0379 2017 http://jas.macrothink.org 137 Cl%, total phenolic and flavonoids in leaves. It can be concluded that, foliar spray of nano silicon combined with soil addition of gypsum was the best effective and economic treatment recommended for mitigating the harmful effect of salinity stress on Jatropha plants irrigated with saline water at concentration up to 4000 ppm.

“…Esta diluição da solução do solo favorece a adsorção de cátions divalentes como Ca 2+ à custa de cátions monovalentes, como Na + . O inverso é verdadeiro quando a solução do solo é concentrada devido à evapotranspiração (Qadir et al, 1996).…”

Os solos degradados por sais e sódio, comuns nas áreas irrigadas da região semi-árida, apresentam atributos físicos e químicos desfavoráveis à agricultura. A baixa disponibilidade de nutrientes, como o fósforo, nesses solos é uma realidade. Desta forma o emprego de corretivos e o estudo da disponibilidade de fósforo nessas áreas constituem-se numa alternativa para reintegrar tais solos à produção agrícola. Conduziu-se um experimento para verificar o efeito da aplicação de quatro níveis de gesso (0, 50, 100 e 200% da necessidade do gesso) e quatro dosagens de fósforo (0, 150, 300 e 450 mg dm-3), em solo salino-sódico (Cambissolo - CE 4,2 dS m-1, PST 52, pH 6,3 e CaCO3 65 g kg-1) de textura franco-argilosa (areia 18,8%, silte 43,9% e argila 37,3%), do Perímetro Irrigado de Capoeira - São José do Bonfim, PB. Analisaram-se os parâmetros fósforo disponível, Na, Ca, Mg, pH, PST e CE, cujos dados revelaram que o corretivo exerceu efeito significativo no aumento de cálcio e fósforo do solo e na redução da PST e pH. A aplicação de gesso e fósforo promoveu aumento significativo nos teores de P do solo e redução do Na. Para as demais variáveis, o efeito dos tratamentos foi não significativo.

“…How to remediate the saline-alkali land in northwestern area has become a key problem causing national concern and scientific study. Coal ash is one of the main wastes affecting environment in the world at present [3], but its physicochemical property test indicated that the bulk density, pH value and alkaline matter content of soil could decrease by adding coal ash [4][5][6]10]. Coal gangue is an ideal matrix to carry animalcule of nitrogen-fixing, phosphate-dissolving and potassium-releasing.…”

Abstract-Through pot experiment, the paper explored the impact of saline-alkali soil ameliorated by coal ash and coal gangue on the growth tamarisk. The experimental results indicated that the amelioration effect of saline-alkali soil by adding 15 % coal ash and 15% silt was distinctly better than adding 10 % coal ash, 10 % coal gangue and 10 % silt, also better than adding 20 % coal ash. Adding coal ash to matrix had acceleration effect in enhancing sprouting rate, shortening branches' sprouting time and improving sprouted branches' survival rate of tamarisk. Adding different amounts of coal ash to saline-alkali soil had different amelioration effect, that was 15 %>20 %>10 %. This experiment reached the original requirements and expectations, and the analysis of acquired data was scientific and practicable, so it had reference significance.
