Soil chemical properties, such as Carbon and Nitrogen levels, are crucial for fulfilling the basic needs of plants. The presence of secondary and tertiary nutrients plays a vital role in constructing soil structure, influencing the survival of normal microbial flora, seeds, and later plant growth. The use of chemical fertilizers addresses nutritional deficiencies, but reports indicate that only 40% is utilized by plants, leading to soil issues like salinity and drought logging. When soil lacks essential nutrients, external amendments are necessary, impacting plant growth and crop yield by enhancing normal microbial flora i.e. Plant growth-promoting rhizobacteria (PGPRs). Recognizing the significance of both chemical nutrients and physical properties for healthy plant growth, a soil amendment called "Fertisol soil" was developed. This involved adding basic and secondary nutrients to the soil. The amended soil underwent analytical characterization and was compared with natural soil through chemical analysis and microbial growth assessments. Comparative studies using the amended soil showed improved plant growth and flowering capacity compared to control plants in terms of height and flowering. This highlights the positive impact of balanced nutrient amendments on soil health and overall plant performance.

In this study, the activated carbon that was obtained from date seeds, after heating at 500 ºC, was used to remove methyl red dye from its aqueous solutions. Different parameters were applied including (the effect of dose, the effect of adsorption time, and the effect of pH value). The extent of dye removal increased with increasing adsorption time. An acidic pH is optimal for enhancing dye adsorption. The Langmuir isotherm was applied to the data obtained, and its constants were calculated at the optimum conditions. According to Langmuir isotherm, the monolayer saturation capacity (q _m ) is 0.9 mg/g. The study concluded
that date seeds activated carbon (DSAC) has demonstrated effective adsorption results in removing methyl red and suggests its potential for use in other adsorption studies.
