“Improving Growth with Science and Technology Since 1976”
Soil Analysis

Soil sampling is one of the simplest land management tools available to today’s grower. The science behind soil analysis establishes a baseline inventory of soil composition. Using the information that soil sampling provides to manipulate soil composition is what fertility is all about. Waters Agricultural Laboratories, Inc. combines the best in equipment, personnel, experience and reputation to provide testing results you can trust. And…with our FastBack 24-48 Hour Turnaround Times, waiting weeks for those results is a thing of the past.

Below please find listed our soil analysis packages. If additional tests are needed, please contact the lab for more information.

The following information will help you gain a better understanding of your soil results and the role of primary, secondary and micronutrients.




Helps form amino acids which are the building blocks of proteins



Is utilized in the formation of nucleic acids and other chemicals which help in the development of healthy root systems, early growth, early maturity and seed production



Is similar to phosphorus for root formation and also appears to promote disease resistance. It increases the size and quality of fruits




Is sometimes referred to as the “4th primary nutrient” since it must be present to form protein



Is used in root system and leaf development and is combined with other elements to form cell walls. It also helps by activating other enzyme systems



Is the central atom of the chlorophyll molecule which makes it absolutely necessary for photosynthesis. It also plays a role in phosphate metabolism, plant respiration and enzyme systems

Micro Nutrients



Is necessary for chlorophyll formation and also acts as a catalyst for other plant reactions



Acts as a catalyst for chlorophyll formation and also carries oxygen. In addition, it helps form certain respiratory enzyme systems. These functions make it critical to photosynthesis



Activates many metabolic reactions in plants and is directly involved in photosynthesis. It accelerates germination and maturity and increases the availability of phosphorus and calcium



Facilitates a plants proper use of nitrogen. It is also used to convert inorganic phosphorus to organic forms



Is necessary for the production of chlorophyll and carbohydrates and aids in the creation of plant growth substances, enzyme systems, and metabolic reactions



Is essential for germination of pollen grains and growth of pollen tubes and for seed and cell wall formation. Other functions aid in protein formation



Is used in photosynthesis and helps promote a more disease resistant plant
