Soil & Fertilizer
The Denele soil test is a process by which elements (phosphorus, potassium, calcium, magnesium, sodium, sulfur, manganese, copper and zinc) are chemically removed from the soil and measured for their “plantavailable” content within the sample. The quantity of available nutrients in the sample determines the amount of fertilizer that is recommended. A soil test also measures soil pH, humic matter and exchangeable acidity. These analyses indicate whether lime is needed and, if so, how much to apply.
Why Do You Need A Soil Test?
Knowing the makeup of your soil helps you to encourage plant growth by getting the best lime and fertilizer recommendations.
When growers guess about the need for lime or fertilizers, too little or too much is likely to be applied. By using a soil test report, the grower does not need to guess.
For Example: When applying too much lime, soil pH may rise above the needed level, which causes nutrients such as iron, manganese, boron, copper and zinc to become less available to plants. If a homeowner purchases one bag of fertilizer, and only one bag of lime, it may present a problem.Based on an average lawn size of 5000 square feet, one bag of fertilizer may be enough. Applying one bag of lime over 5000 square feet, however, will have little effect on soil pH. Expand that to full-scale farming and you can see how much of a mess things can become.
* Diagnoses whether there is too little or too much of a nutrient.
* Promotes environmental quality.
* Saves money that might otherwise be spent on unneeded lime and fertilizer.
