Quizplus · Accepted Answer

Horizon A is the top layer of soil and is the most important for farmers to plant crops because it contains the highest concentration of organic matter, nutrients, and minerals that are essential for plant growth. It is also the layer where most of the biological and physical activities occur, such as root growth, nutrient uptake, and water retention. Other soil horizons may have limitations for plants, such as insufficient nutrients or too much water, making them less suitable for crop production.
