Which is better lime or gypsum?

Gypsum therefore improves soil conditions much more rapidly than lime and will affect soil conditions to a greater depth than lime will. Gypsum will supply calcium to deeper depths than lime. This will improve subsoil conditions, and allow for greater root growth (better nutrient and water efficiency).

Is too much gypsum bad for soil?

Most farmers and gardeners resort to using gypsum to salvage Alkali soils. … However, applying too much gypsum in the soil may also mean eliminating essential nutrients from the soils such as aluminum, iron, and manganese. Removal of these nutrients may lead to poor plant growth.

Why is my garden soil so hard?

Excessive weight and rain close the open pores between the soil particles; as a result, the soil hardens. Clay soils often drain very slowly after rainfall, and then they harden and crack when the weather turns dry and warm. To avoid compacting soil, create paths to avoid walking on growing areas.
