Impact of some Organic and Inorganic Amendments on some Soil Properties and Wheat Production under Saline-Sodic Soil

Abstract

Two field experiments were conducted at two sites in Sakha Agric. Res. Station Farm, North Delta, during two successive winter seasons, 2017/2018 and 2018/2019 to study the effect of individual and combined applications of gypsum, compost tea and biochar on some soil properties and wheat (Triticum aestivum, L) productivity under saline and saline-sodic soils. Gypsum requirements (G), 400 L compost tea (C), 1 Mg biochar (B 1) or 2 Mg biochar (B 2) were applied. Data revealed that application of G+ C+ B2 decreased soil ECe by 28.06 and 13.16 %, SAR by 17.23 and 8.92 %, ESP by 17.23 and 8.92 % for site 1 and site 2, respectively as compared to the control. While, the sodium removal efficiency (RSE %) with different treatments was increased in somewhat according to the following order: G+C+B 2 ˃ G+C+B 1 ˃ G+C ˃ G+B 2 > G+B 1 ˃ G ˃ C+B 2 > B 2 > C+B 1 > C > B 1 compared to that of the initial soil. Also, the application of different soil amendments decreased soil bulkdensity and increased soil porosity after the two growing seasons. The plant height, 1000-grain weight, grain yield and straw yields of wheat were significantly increased with different treatments.

PRODUCTIVITY OF HEAVY CLAY SOILS AS AFFECTED BY SOME SOIL AMENDMENTS Combined with irrigation regime.

“…So, the effect different treatments on soil bulk density followed the ascending order such as: compost > gypsum > zeolite > magnetite >Sulphur> control. The obtained results are similar to those reported (Hussain et al, 2001;Antar et al, 2008;Abdel-Fattah et al, 2016;Bayoumy et al, 2019).…”

“…The effect of application on salinesodic soil reclamation have shown that the soil receiving gypsum at higher rate removes the greatest amount of Na+ from the soil columns and causes a substantial decrease in soil electrical conductivity (EC) and sodium adsorption ratio (SAR). The obtained results seem to agree with Abdel-Fattah et al 2012, Amer and Hashem (2018) and Bayoumy et al (2019).…”

“…The data cleared that application of compost had positive effect on EC e due to improving the soil physical properties; hence it led to remove Na + fare from root zone. These results are in harmony with those obtained by Abdel-Fattah et al 2016, Amer and Hashem, (2018) and Bayoumy et al (2019). Finally, the effect of different soil amendments on soil porosity can be arranged in following ascending order compost> gypsum > zeolite > magnetite >Sulphur> control.…”

“…Saied et al, (2017) found that the positive effect of compost on decreasing of the bulk density and increasing the soil porosity and IR values, consequently ease leaching the salts from upper soil layer and movement far by mole drainage (Amer and Hashem, 2018).Finally, the application of soil different amendments treatments on improving soil health by enhancing soil quality parametersbulk density, soil porosity, aggregation, structure and water holding capacity. The obtained results are similar to those reported (Hussain et al, 2001;Antar et al, 2008;Abdel-Fattah et al, 2016;Amer and Hashem, 2018;Bayoumy et al, 2019). Table 4 showed that the soil amendments under irrigation effectively in decrease of soil salinity (ECe) than before experiment instillation in the soil (0-60cm depth).…”
