This doesn't necessarily equate to how much NPK to add. That will vary depending on what you already have present in your soil and other factors. Also, plants don't use NPK and other nutrients in a linear manner. Tomatoes, for example, will extract more N early in the growing cycle and more K later when they are setting and maturing fruit. |
fortyonenorth looking for both. First the ballpark of what each group of plants uptake and second the different stages they take it up as you mentioned about tomatoes. Take cucumbers for example what are their uptake cycles. corn uptake cycle etc.
Thanks for the link.
