The test is used to mimic the function of roots to assimilate minerals.
What does soil testing tell you?
The soil test will tell you the percentage of organic matter you have in your soil and will “credit” you a certain amount of nitrogen for it. This will minimize the risk of applying excess nitrogen which might then wash out of your soil and into surrounding waterways.
What information does a soil test provide?
Basic soil tests pinpoint the amount of organic matter, the pH and the level of macronutrients (nitrogen (N), phosphorous (P) and potassium (K)). These standard tests only provide information on soil characteristics. That means they do not test for pollutants, pesticides or other potentially toxic compounds.

What is the electrical conductivity of fertilizer?
Most fertilizers (except urea) are salts and when placed in solution they conduct electricity. Thus, the electrical conductivity (EC or soluble salts) of a substrate solution is indicative of the amount of fertilizer available to plant roots.
What is the purpose of soil sampling?
The goal of sampling for a soil test is to efficiently collect samples which best represent the nutrient status of the crop or the problem to be diagnosed. The first step is to identify the crop unit (s) to be sampled – bench, greenhouse, etc. In a mixed greenhouse, crops of different species must be sampled separately for the tests to have any value. If a problem is being diagnosed, it is best to have a sample from both normal and abnormal plants for comparison.
When to conduct media test?
Conduct media tests during the growing season to manage crop nutrition and soluble salts levels. Always use the interpretative data for the specific soil testing method used to avoid incorrect interpretation of the results.

How often should I test soil conductivity?
Finally, certain fertilizer practices, as well as growing media, will need to undergo testing at least once a month.
What is the difference between acidic and alkaline soils?
While it may take years to adjust the soil’s pH imbalance, acidic soil requires the application of limestone derived products while alkaline soils would need sulfur products. Fertilizers and other Practices. Fertilizers also play an important role in successful and optimized crop production.
How to determine the presence of minerals and nutrients in the soil?
The presence of minerals and nutrients found in the ground is determined through the soil’s pH levels. When conducting proper soil testing, the soil’s pHis measured. It shows the ground’s acidity or alkalinity read on a scale ranging from 0 to 14. A low scale shows harsh acidity while a high scale indicates extreme alkalinity.
