What Is The Best Way To Add Iron To The Soil

Question

The soil in my location if clay based and I have read that adding iron to the soil will improve growing conditions. What is the best way to add iron to the soil?

Answer 1

Actually, clay soil will contain quite a bit of iron, already! Amending clay soils should be done with soft organic material, such as perlite, vermiculite, coco-coir, peat-moss, or other materials to break up the clay content. By far, the best way to amend the soil will be compost. Well composted organic material will break up the stickiness of the soil, while adding all of the nutrients that will be missing.
