Soil Health Matters: The Foundation of Sustainable Agriculture


Sustainable agriculture, in the face of increasing global population and environmental concerns, is pivoted on a fundamental aspect – soil health. Beyond being a mere substrate for plant growth, the soil is a living, dynamic ecosystem that sustains life on Earth. In this comprehensive exploration, we will delve into the intricate world of soil health, unravel its profound significance in sustainable agriculture, and dissect the practices that contribute to its preservation.

I. Understanding Soil Health:

  • A. Soil Composition:
