If a nutrient is found to be deficient at this stage of growth, either the rate of fertilizer applied was not sufficient, or nitrogen and other mobile nutrients may have been lost. One example where plant analysis is used on a very regular basis is irrigated potato production. A plant sample every week gives information to the dealer or consultant on a regular basis. This provides an opportunity to become familiar with interpreting data as the crop progresses. It also supplies the dealer or consultant with much more information with which to make fertilization decisions.
Planning is a very important part of using plant analysis.
Allowing yourself enough time to collect the samples, have them analyzed and receive the information is critical. Please give us a call if you need sampling supplies or additional information about plant analysis.
