Testing Services

Soil Samples:
Most everyone will want to get the Routine Test which will give them the levels of the main nutrients and the pH of their soil. The Routine Test will give you ratings and recommendations for needed fertilizer and if the pH is out of range a lime or sulfur recommendation will be given to correct it. Several Optional Tests are available for special needs.

Levee Samples:
The Levee Test is a combination of the Routine Test which provides pH and extractable nutrients and the Flood Test which provides water soluble nutrients, salts, conductivity, and SAR. This test is provided for clients working on the levee system in south Louisiana.

Plant Tissue:
Plant analysis provides immediate diagnosis of nutrient deficiency, toxicity or imbalance for major and micro-nutrient elements. It serves as a supplemental tool to soil tests. It can monitor the effectiveness of your adopted fertilizer practices and help to correct nutritional problems during early growth season. Commonly tested nutrients include nitrogen, phosphorus, potassium, magnesium, zinc, copper, boron etc.

Irrigation and Pond Water Quality:
These tests are important for diagnosing irrigation water quality and for helping to manage pond water properly. Tested parameters include pH, Conductivity, Salts, Na, K, Mg, Ca, Fe, Mn, S, Cl, Nitrates, Alkalinity, Sodium Adsorption Ratio (SAR), and Hardness.

Soil-less/Potting Mixes:
Mixes are composed of lightweight, natural and processed material such as peat, perlite, vermiculite, sand, bark, coconut fiber, compost, and similar materials. These products are mixed together in various combinations and contain less than 20% field soil. Soluble nutrients are tested for nutritional status of soil-less/potting mix medium. These tests help you to correct nutrient problems associated with soilless/potting mix medium. Commonly tested parameters include nitrate, and soluble phosphorus, potassium, calcium and magnesium. In addition, pH is also determined for the medium reaction for optimum plant growth.
