Traditionally we have all been taught that we measure the nutrients in the soil, work out an index and add what we think is missing to make up the difference. If only it was that easy!
This is the law of the maximum: – When an over supply of one element or mineral restricts the availability of others. A good example of this is over liming. If you raise the pH of your soil slightly too much through over doing the calcium carbonate, you can lock up many of the other nutrients you need for unrestricted growth. So how is too much of one mineral spotted?
Ask yourself this question –
Then the answer is in your soil. One or more of the nutrients your crops need isn’t being provided. Effective soil testing can tell you which ones. An excess of Iron, Calcium, Magnesium and Phosphate can all interact and restrict access of key nutritional minerals to your crop.
