Front

What is the significance of iron in calcareous soils?

Back

Iron is a micronutrient that is often deficient in plants grown on calcareous soils.

Front

Explain the role of vermiculite in soil nutrient availability.

Back

Vermiculite can trap nutrients like NH4+ and K+, making them less available to plants.
