Are you sampling at perennial growth stages listed below?

Soil Testing

A routine soil test will report soil pH, percent organic matter, and will provide estimations of plant available phosphorous and potassium.  When a soil test accompanies a tissue test, it is another tool in the ongoing management of a fertility program. When samples are collected from each fertility management unit annually, trends can be followed over time and adjustments made as necessary.

Includes pH, buffer pH, organic matter, phosphorus, potassium, calcium, magnesium, sulfur, boron, zinc, manganese, copper, iron, soluble salts and cation exchange capacity (CEC)

Plant Testing

Tissue testing is the backbone of any nutrition management plan for cranberry marshes. Routine tissue analysis detects low nutrient concentrations before visible symptoms or yield reductions occur. Tissue testing predicts the fertilizer needs of your crop, diagnoses problems, and evaluates effectiveness of your fertilizer program. 

Includes total nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, manganese, zinc, copper, iron, sodium, aluminum and boron.

Water Testing

Analyzing water samples can be useful for monitoring nutrient levels necessary to crop development. Testing is recommended annually, depending on grower standards.Package includes calcium, magnesium, iron, sodium, manganese, potassium, hardness, sulfates, chlorides, conductivity, pH, boron, orthophosphate, alkalinity, and nitrate.
