Dolomite Lime – How Garden Lime Can Cause Problems

2021-12-17 · Dolomite is recommended to correct calcium and magnesium deficiencies. Depending upon magnesium levels, dolomitic lime can often cause more harm and trouble, however, than its initial cost. Excess magnesium is often associated with soil stickiness, crusting, compaction, reduced aeration, and releasing nitrogen from the soil pound for pound.

Diatomaceous earth

Diatomaceous earth or diatomite is a light-colored sedimentary rock composed chiefly of siliceous shells (frustules) of diatoms. Diatomaceous earth is a soft and friable rock. It leaves hands dusty if touched and has a fragile feel as if it has a delicate and light-weight internal structure. This feeling is not misleading.
