Manufacture and Recycle Environmental Waste Materials to Eliminate Soil Salinity

Abstract:

Salinity, or accumulation of dissolved salts, is considered a significant problem affecting on agriculture section in Iraq generally and Basra particularly. Therefore, this research aims to explore the potential of eco-friendly materials to reduce soil salinity and enhance growing of plant. These materials are laboratory prepared and produced such as zeolite stone, humic acid and wood vinegar. Then, physical and chemical properties of saline soil were determined such as (pH, EC, Ca, Mg, Na, Cl, PO₄and SO₄) before and after adding the synthesized eco-friendly materials divided into four groups (G1, G2, G3, G4) with three various ratios (1, 3, 5 g) for each kilogram of saline soil placed in pots that planted with Cress seeds (Lepidium sativum) for observation and analysis. The results indicated remarkable improvements in soil characteristics. The best treatment was found in G4 combination of zeolite stone, humic acid and wood vinegar with added ratio (5g). The results showed a great achievement in reduction of electrical conductivity (EC) from approximately (~18 mS/cm to below 1.3 mS/cm) reflecting over 89% of salinity removal efficiency. Furthermore, pH levels of soil, which initially showed alkalinity (~8.3), were adjusted to be more optimal values around 6.8–7.2 depending on used material. Moreover, decrease the concentrations of elements that forms the main source for salinity in soil. Improvements were also recorded in growth of plants and nutrient retention. Statistical analysis by (one-way ANOVA test) showed a significant differences between groups with a significance level (P ≤ 0.05). These findings suggest that integrated use of zeolite, Humic acid, and wood vinegar could holds high potential for restoring the health of saline soils in southern of Iraq, however, more research are needed to explain and analyse the chemical reaction between these synthesized eco-friendly materials and salts of.
