    The choice between fertilizers and manure impacts soil fertility management by influencing nutrient availability, soil structure, and microbial activity. While fertilizers provide specific nutrients in readily available forms, manure improves soil structure, adds organic matter, and sustains microbial diversity, enhancing long-term soil fertility and resilience.

  4. Light soils have low water-holding capacity due to their high sand content, making them vulnerable to drought. Their porous structure allows water to drain quickly, leaving little moisture for plants during dry periods. This exacerbates the impact of drought, leading to reduced plant growth and cropRead more

    Light soils have low water-holding capacity due to their high sand content, making them vulnerable to drought. Their porous structure allows water to drain quickly, leaving little moisture for plants during dry periods. This exacerbates the impact of drought, leading to reduced plant growth and crop yield.

  5. Drought in rain-fed farming areas diminishes soil moisture crucial for crop growth, stunting plant development and reducing yields. Lower rainfall leads to water scarcity, hindering agricultural production and risking crop failure. Farmers face financial losses, food shortages, and increased vulneraRead more

    Drought in rain-fed farming areas diminishes soil moisture crucial for crop growth, stunting plant development and reducing yields. Lower rainfall leads to water scarcity, hindering agricultural production and risking crop failure. Farmers face financial losses, food shortages, and increased vulnerability to economic instability, exacerbating food insecurity in affected regions.
