Soil Nutrient Interaction

Antagonistic nutrients have a negative effect on the uptake of other nutrients. Possibly you have seen that an excess of Phosphorus (P) creates an imbalance with Iron (Fe) and Zinc (Zn)?

Some nutrients do the opposite and their presence has a positive effect on the uptake of other nutrients. These are called Stimulant Nutrients and an example of this is would be when increasing the nitrogen (N) availability to the plant, it will allow the plant to take in more magnesium (Mg) and up the demand for it. To show this we have the Mulder Chart.





Liebigs Law of Minimum Yield comes into play when you look at the whole picture.





This also has to be overlaid with a PH nutrient availability chart.

Easier to read mineral interaction chart. Still a mindfuck

This chart shows how an excess in Potassium can help free up Mn and Fe but it decreases the availability of Ca, Mg, P, B and N and potentially give you deficiencies as a result even though it is still present in the soil.

Hey NaturalFarmer, good thread. The relationships between these minerals are based on proper proportions. These charts are cool, but they aren't that easy to understand just looking at them. Some minerals have natural antagonism with each other when they're in proper ratios which is normal and necessary for good uptake by plants, e.g., manganese and iron, copper and zinc, phosphorus and potassium, etc. And some of those relationships on the chart are synergistic with proper ratios. And some are antagonistic when one gets out of proper proportion, e.g., too much potassium limiting the uptake of calcium which is the probably most common imbalance.

You're onto to some very cool info though
