THE IMPORTANCE OF SOLUBILITY IN SOIL CONDITIONERS
Solubility in soil conditioners, such as gypsum, lime and dolomite are very important. The key to solubility is mainly in particle size. The finer the product, whether it be in gypsum, lime, dolomite or any other natural occurring mineral the quicker the result.
Natural raw gypsum, aglime and dolomite should be applied at least six months before cropping to achieve worthwhile results. Products such as Mine2g gypsum which have a mean particle size below 0.5mm and 99% passing 2mm mesh will have a high solubility compared to standard natural gypsum.
Recycled gypsum, superfine lime and dolomite however are a different story. Recycled gypsum from plaster board has been refined to very small particles in the production of the plaster board, making it far more soluble than raw gypsum, in other words, you can apply it just before cropping and get a good result.
In the case of Superfine lime and dolomite against aglime, you will achieve a much quicker response. The smaller particles are the secret to quicker results and of course higher yielding crops.
