Product Description
Soil Salt Meter Model:XR24-T5 Cat.No:M36320
SOLUBLE SALTS ----The main ingredients of most fertilizers are nitrogen, phosphorus, and potassium. Together, these and other additives intended to enrich the soil may be called SOLUBLE SALTS. These elements are "carried" in the fertilizer compounds. For example: The potassium carriers are usually potassium sulphate or potassium chloride.
The nitrogen is usually sodium nitrate. The phosphate is contained in the compound calcium phosphate. Fertilizers are often spread in a granular and water soluble form.
No matter what fertilizer method is used and whether applied lovingly to a single indoor house plant, or on your lawn, or used professionally in greenhouses and nurseries, or spread over wide acreage in farming, this fact exists: Fertilizer applied that isn't readily absorbed by the soil. or absorbed by the plant, will tend to build up and, unless you take action you will kill your plants!
At the minimum, the danger is reduced growth and yield. This SOIL SALTS METER can help. With it, you can measure the soluble salts concentration to determine if your current fertilizer practices are creating a danger to your plants.
The criteria separating the "SAFE" from the "DANGER" zone is a generally accepted level agreed to by a group of scientists in a midwestern Agricultural Experiment Station. The level is approximately 150 mhos x 10-5 (or 1.5 mhos x 10-3).
