-Major nutrients have been researched for many years and since they are required in large amounts by plants for optimal growth there is a lot of data available. Interactions have been studied, but for the most part the major and secondary nutrients are pretty straight forward when it comes to soil test results and recommendations. Nitrogen is an exception to this rule; we will not discuss it within this paper. We know that as soil pH drops and becomes more acidic the phosphorous in the soil becomes less available due to tie up. In our recommendation system we compensate for this by recommending a higher level of phosphorous in the soil when compared to a phosphorous level in a more neutral soil pH. This additional phosphorous helps overcome the tie up making more available for the plant. This additional phosphorous has been demonstrated with higher P levels in the plant analysis.+Major nutrients have been researched for many years and since they are required in large amounts by plants for optimal growth there is a lot of data available.

-The equation for copper contains soil pH and soil phosphorous level. The manganese equation contains organic matter and soil pH as part of the components. If you would like to discuss the full equations please contact one of the agronomists at the lab and we will be happy to talk with you on a one to one basis. +The equation for copper contains soil pH and soil phosphorus level.
