We have analyzed some soil samples for total phosphorus, total nitrogen, water content, pH and soil organic carbon. For meaningful inferences and conclusions, these data have to be compared to some standards (or limits).
This is a very generalised question. These soil fertility limits need to be worked out for a given crop. Unless , we define the crop and the productivity level, such soil fertility limits will no longer be so effective and meaningful...
