Solution Analysis
Purpose
Solution analysis measures plant nutrients and other parameters relevant to agricultural production in groundwater, surface water and nutrient solutions. Laboratory results and recommendations aid in management of irrigation water quality, hydroponic and fertigation systems, livestock and poultry drinking water, and aquaculture and fish pond management.
The Solution Analysis Laboratory does NOT test for:
- microorganisms, such as bacteria, fungi, viruses, and protozoa
- organic chemical contaminants, such as petroleum products, pesticides, and herbicides
The Agronomic Division accepts solution samples from both individual growers and research institutions, nation-wide. Select the submission process below that best describes your operation. If you are uncertain about your submission category, please contact the Laboratory Director or Agronomist below.
Frequently Asked Questions
No. We test water for inorganic nutrients and other parameters that are relevant to plant nutrition and fish and livestock production. Testing for microbial pathogens, algae, protozoa, etc. are available from private labs in N.C.
We test water for nitrates, ammonia, and phosphorus, which are important contaminants in surface and ground water and may stimulate algal overgrowth. We do not test water for herbicides, pesticides, petroleum products or other organic contaminants. These tests are available through private labs in N.C. at a high cost.
No. If you have a problem with algae or aquatic plants, the Solution Analysis can help to determine if excess nutrients are stimulating overgrowth. To treat algae or aquatic plants, it is essential to identify it first. Please contact NC Dept. of Environmental Quality Aquatic Weed Specialist, Rob Emens at 919-707-9012. You can also refer to the NCSU Fisheries and Pond Management website for further information.
We test for nitrate, which is important for drinking water quality, but we do not test the many chemicals that are relevant to human drinking water. If you suspect a specific contaminant in your drinking water, you should contact your county public health office.
No. We test for elements and other parameters that are important for fish health. We do not test for microbial pathogens, algae, or industrial contaminants.
