Abstract

Soil quality is a fundamental determinant of agricultural productivity and environmental sustainability. The integration of nano additives into soil has emerged as an innovative approach to enhance soil properties, fostering more sustainable farming practices. This study explores the effects of inorganic and bio-based nano additives—such as chitosan, cellulose, silica, and titanium dioxide—on soil pH, moisture, aggregate stability, nutrient availability, and microbial activity. Laboratory experiments were conducted with varying concentrations of these additives to assess their impact. Results revealed a 25% improvement in aggregate stability with the application of 1% nanoclay by weight, while nano-silica (0.5%) enhanced water retention by 15%. Biochar (3%) contributed to a 20% increase in organic matter content, enriching soil fertility. Furthermore, microbial activity increased across all additives, with nano-silica leading to a 30% boost in microbial biomass carbon, indicating an improved soil health. To deepen the understanding of nano-soil interactions, characterization techniques such as scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) were employed. The study demonstrates that nano additives hold a significant potential for enhancing soil properties, offering sustainable solutions for agriculture. Artificial intelligence (AI) and statistical tools can be used to further analyze the vast experimental data, optimizing the selection of nano additives for specific soil conditions. The integration of AI-driven analytics may enhance the precision and applicability of these findings, ensuring more efficient and targeted soil management practices.
