Exchangeable Sodium and Gypsum Requirement Test Kit (100 tests)

Exchangeable Sodium and Gypsum Requirement Test Kit (100 tests)

Alkaline soils are characterized by a low electrical conductivity (EC), high exchangeable sodium percentage (ESP) and the presence of carbonate and bicarbonate sodium salts. Highly alkaline conditions hinder plant growth since it reduces the solubility of necessary nutrients such as Iron, Copper and Manganese.

Chlorosis, for instance, is a typical disease affecting leaves due to Iron and Manganese deficiencies. It is possible to correct soil alkalinity by adding proper conditioners (usually gypsum) to reduce Sodium's adverse effects and return the pH to an acceptable range.

The exact quantity of gypsum needed for the correction can be calculated with this kit. This kit lets you fix the problems set forth by waste dumping or previous run-off problems. This allows you to turn useless soil into arable land.
