Abstract
The regeneration of pecan orchards is on the rise in Arkansas. Many orchards were left un-attended as family members lost interest or the cost of pecan production made the venture un-profitable. Regardless of the reason, many of the orchards were left un-attended in past years. As a new generation comes on the scene, so does the revitalization of these once deserted orchards. With the surge in interest, so comes the need for proper care of the orchards starting with the orchard floor. The need for renewed soil and tissue sampling is more important now than ever. The " Big Three" macro nutrients (Nitrogen, Phosphorus and Potassium) have a way of making their needs known, but when it comes to the micro-nutrients (those nutrients needed in smaller amounts) the importance is simply overlooked too much of the time. It comes down to producing average pecans or producing a higher quality pecan that will in turn be more valuable when marketing these delectable treats.
With advances in unbiased science-based technology the progression given to what is needed to produce a quality pecan has changed. The need for tissue sampling, advanced pesticide use, and attention given to micro- nutrients have never been more important. There are several micro-nutrients that will leave other producers wondering what the difference is between your orchard and theirs. Zinc plays a crucial role in leaf expansion and flower elongation. Iron is essential for chlorophyll production; Manganese helps with enzyme function to avoid pale leaves. Magnesium is needed for increased photosynthesis. In addition, the proper amounts of boron, copper, calcium and sulfur all feed into the equation for pecans that are of peak quality.
A complete soil test of the entire orchard is needed to evaluate the needs of these micro-nutrients. In addition, trapping for insects such as brown and green aphids, pecan case nut bearers, pecan weevils and aphids is essential. With all this said, let us not forget the first issue, that of cleaning the orchard floor and burning dead brush to help ensure the production of quality pecans .
