“…The results presented here are consistent with those reported by Yermiyahu et al, (2001), which indicate that OM plays an important role in controlling B concentration in the soil solution, and that it has a prominent effect in reducing B uptake by plants. The Na + in roots was also decreased by the application of 6% OM; this prevents root from salt injuries and roots can grow as shown in Table 2 (Clark et al, 2007). These results are also in agreement with Yang et al (2004) and Shaaban et al (2013).…”

“…The physical, chemical and biological properties of salt-affected soil are improved by application of organic matter (OM), leading to enhanced plant growth and development by accelerating the exchange of cations in soil solids and leaching of salts from the root zone (Clark et al, 2007), hence preventing salt injuries and allowing roots to grow more uniformly. The decaying organic matter increases soil CO 2 concentration, releases H + , enhances CaCO 3 dissolution and liberates more calcium for sodium exchange (Ghaffor et al, 2008).…”

To mitigate the effect of salt stress and excess B in soil and consequently increase crop yield and improve the behaviour of cv. "Poncho Negro" there are low-cost strategies such as the application of organic amendments. This study aimed at remediating excess salt (150 mM NaCl) and B (20 mg L -1 B) in soil using organic matter treatment (4% and 6%). Stress was supplied by irrigation. The rate of net CO 2 assimilation, B, Na + , K and Ca 2+ content, soluble sugars and proline were measured. All growth parameters measured were higher with 6% organic matter (OM) in soil than with 4% OM, including salinity treatments and excessive B, while Na + and B concentrations were reduced in leaves and roots. The photosynthesis rate was maintained at the level of control plants with 6% OM applied in soil in treatments with salinity alone and with excess B. In the salinity alone treatment there was a marked increase in the content of compatible solutes, but with the application of 6% OM their content was reduced by more than 100%. The remediation of salt and boron-affected soil by addition of organic matter (6%) is an effective way to improve the behaviour of tomato.Key words: organic matter, boric acid, salinity, Solanum lycopersicum L.

“…Indeed, it is under high level of soil salinity the highest contents of these important nutrients have been recorded. According to Clark et al (2007) and Bernal (2004, 2008), PM improves the mineral nutrient status of plants in saline soils through supply with abundant nutrients, particularly N and K + . Moreover, out results evidence that potato plants accumulate more K + in their leaves than Na + in response to PM application and under our field conditions of soil salinity (up to EC = 5.9 dS/m).…”

In hot arid lands, soil salinity, irrigation with brackish waters and the massive use of mineral fertilizers are major constraints for the development of potato cropping. The current field experiment was conducted in the Sahara Desert of Algeria in order to highlight the effect of organic fertilization on the improvement of potato production and the increase of plant salt-stress tolerance. The variation of yield production parameters and nutritional status of plants were evaluated through a split-plot design including six increasing rates of poultry manure (PM) (0, 20, 30, 40, 50, 60 mt/ha) tested in three experimental sites with increasing salinity levels: low saline soil (electrical conductivity 'EC' = 0.9 dS/m), saline soil (EC = 2.2 dS/m) and high saline soil (EC = 5.9 dS/m). The results revealed a significant and proportional increasing of all studied yield parameters (number, seize and yields of tubers) with the increase of PM rates compared to the control. The effect of the interaction (PM × salinity level) showed that the highest yield (44.55 mt/ha) was recorded in plots treated with 60 mt/ha of PM in high saline soils. The assessment of nutritional status at flowering stage of potato plants demonstrated that concentrations of K+ and N increased while Na+ concentrations decreased, in both leaves and roots, as PM rates increasing, principally beneath high salinity level. Our findings suggest the dose of 60 mt/ha of PM is an optimal amount producing the best tuber yields under saline conditions in arid soils.

“…The released H + enhances CaCO 3 dissolution and liberates more calcium (Ca) for sodium (Na) exchange (Ghafoor et al 2008). Moreover, organic materials improve the soil physicochemical properties that accelerate exchange of cations on soil solids and leaching of salts from the root zone (Clark et al 2007), hence preventing root from salt injuries and roots can grow more smoothly. The conjunctive uses of farm manure with gypsum significantly improve soil physicochemical properties of sodic soils as compared to their alone application (Ullah and Bhatti 2007).…”

Combined application of organic and inorganic amendments was known to play a significant role in improvement of soil properties. A field experiment was conducted to explore the effects of gypsum, farmyard manure and commercial humic acid application on the amelioration of salt affected (saline sodic) soil. During this study, soil pH, electrical conductivity, sodium adsorption ratio, responses of root length and rice paddy yield were examined. Application of gypsum with or without farm manure and commercial humic acid decreased soil pH (8.26%), electrical conductivity (from 6.35 dS/m to 2.65 dS/m) and sodium adsorption ratio (from 26.56 to 11.60), and increased root length (from 9.17 cm to 22.6 cm) and paddy yield (from 695.7 kg/ha to 1644 kg/ha). A negative but significant correlation was observed between root length and electrical conductivity, sodium adsorption ratio (r = -0.93; -0.94, respectively, P ≤ 0.05), whereas positive and significant correlation with paddy yield (r = 0.96; P ≤ 0.05).
