Pecan Zinc and Micronutrient Programs for Georgia and Mississippi Orchards
Chemical Dynamics builds zinc and micronutrient foliar programs for pecan orchards in Georgia and Mississippi. Pecans are among the most zinc-demanding tree crops in the Southeast, and soil-applied zinc frequently fails to reach where the tree needs it. SOAR Pecan Mix delivers chelated zinc and supporting micronutrients as a foliar application timed from bud break through shell hardening — bypassing the soil-uptake problem that makes zinc deficiency so common in these regions.
Zinc deficiency is one of the most common and most consequential nutritional problems in Southeast pecan production. The symptoms — mouse-ear leaves, rosetting, small nuts, poor shell fill — are well known. What is less well understood is why soil-applied zinc often doesn't fix the problem. In many Georgia and Mississippi orchard soils, zinc is present at measurable levels but is tied up in forms the tree cannot access, or it moves so slowly through the profile that it never reaches the feeder roots in meaningful concentration.
Foliar zinc application sidesteps that problem. Applied to the leaf surface at the right timing, chelated zinc is absorbed and translocated directly — the tree gets what it needs without depending on the soil to deliver it.
SOAR Pecan Mix combines chelated zinc with the other micronutrients pecans need through the season — manganese, boron, and supporting elements — in a formulation built for orchard spray rigs. The chelation chemistry keeps the zinc active and available, and the Ascophyllum nodosum seaweed extract supports assimilation and leaf retention.
Our reps cover the Georgia pecan belt and Mississippi orchards. They know the varieties, they know the production calendars, and they know which deficiencies show up most often in which counties.

Products for Pecan Programs
SOAR Pecan Mix
Chelated micronutrient blend formulated for pecan orchards. Zinc, manganese, boron, and supporting micronutrients combined with Ascophyllum nodosum seaweed extract and humic and fulvic acids. Designed for foliar application from bud break through shell hardening on a 4 to 6 application per season schedule. Spray-rig compatible.
See SOAR Products →Dyna Gold Zinc
Sodium glucoheptonate chelated zinc for targeted zinc correction in pecan orchards. The glucoheptonate chelation is absorbed and translocated quickly from the leaf surface — faster than zinc sulfate and without the phytotoxicity risk at higher concentrations. Use for targeted zinc applications or when tissue samples show zinc as the primary deficiency.
See Dyna Gold Products →Dyna Gold Manganese
Glucoheptonate chelated manganese for pecan orchards where manganese deficiency accompanies zinc problems — common in high-pH orchard soils across Georgia and Mississippi. Apply as part of a complete foliar micronutrient program or as a targeted correction based on tissue sample results.

How We Work With Pecan Growers
1
Tissue samples tell the real story
Soil tests in pecan orchards often miss the zinc problem because the zinc is there — it just isn't available to the tree. Tissue samples from current-season leaves give a more accurate picture of what the tree is actually getting. Our reps collect samples and review the results with you before making program recommendations.
2
Timing from bud break through shell hardening
Most Georgia extension recommendations call for 4 to 6 foliar zinc applications per season starting at bud break. Your rep maps a program to your orchard's production calendar and fits the CDI products into whatever spray schedule you are already running through the season.

Questions About Pecan Nutrition
Why do pecan orchards need foliar zinc applications?
Pecans are one of the most zinc-demanding tree crops grown in the Southeast. Zinc deficiency — which shows as mouse-ear leaves, rosetting, and poor nut set — is common in Georgia and Mississippi orchards because the soils in these regions often have low zinc availability even when soil test levels appear adequate. Soil-applied zinc frequently does not move to where the tree needs it. Foliar zinc applications at bud break and during the growing season deliver zinc directly to the leaf tissue where it functions, bypassing the soil-uptake problem entirely.
When should I apply foliar zinc on pecans?
The critical zinc application windows in pecans are at bud break in spring, when zinc is needed for new shoot and leaf development, and again during shell hardening when the kernel is filling. Most Georgia pecan extension recommendations call for 4 to 6 foliar zinc applications per season beginning at bud break. SOAR Pecan Mix is formulated to be applied on this schedule.
What is the difference between chelated zinc and zinc sulfate for pecans?
Zinc sulfate is the traditional material used in pecan foliar programs and still works, but it can cause leaf burn at higher concentrations and requires careful handling. Chelated zinc — the form used in SOAR Pecan Mix and Dyna Gold Zinc — is more stable, less likely to cause phytotoxicity, and typically more effective at lower application rates. The glucoheptonate chelation in Dyna Gold is particularly suited to foliar application because it is absorbed and translocated quickly.
Do you have programs for Georgia's primary pecan-growing regions?
Yes. Our reps cover the Georgia pecan belt including the Southwest Georgia production area around Tifton, Albany, and Valdosta, as well as Mississippi pecan orchards. They know the variety differences, the orchard floor management systems, and the spray timing that fits the production calendar in these regions.
Can I use SOAR Pecan Mix with my other orchard sprays?
In most cases yes. SOAR Pecan Mix is designed for spray-rig applications and mixes cleanly with most common orchard inputs. Always do a jar test before mixing with any new material. Your rep can advise on compatibility with the fungicide and insecticide programs common in your area.
