Plant Doctor Clay Breaker Gypsum Granules are a natural, slow-release calcium sulphate in a 1 to 2mm mini prill. They supply calcium and sulphur and are used to improve the structure of compacted or sodic clay soil, without changing soil pH.

Why you'll love it

  • Calcium and sulphur without a pH shift. Gypsum lifts calcium and sulphur levels while leaving soil pH where it is, which matters where the pH is already right.
  • It opens up heavy soil. It improves soil structure and reduces compaction, which helps water infiltration and drainage and reduces surface crusting.
  • Clean to spread. The small prill goes out evenly with very little dust.
  • From garden beds to ovals. It is used in home gardens and lawns, landscaping projects, parks, school ovals, orchards and broadacre farming.

How to use it

Spread evenly over the soil surface at 100g per sqm, which is 10kg per 100 sqm, and water in. A soil test is the best guide to the rate, and gypsum works best within a balanced nutrition program. Apply before planting, during soil preparation or as ongoing maintenance on compacted or sodic ground. Do not combine it with iron-based products.

What's in it

Natural calcium sulphate (gypsum), with calcium at 19% or more and sulphur at 14% or more.

Sizes

  • 4.5kg. The smaller bag, for garden beds and small lawns.
  • 20kg. The larger bag, for whole lawns, landscaping projects and bigger sites.

Specifications

  • Type: slow-release granular gypsum (calcium sulphate)
  • Granule size: 1 to 2mm mini prill
  • Analysis: calcium 19% minimum, sulphur 14% minimum
  • Effect on soil pH: none
