Although pecan roots penetrate a large volume of soil, only a small fraction of the nutrients are available to the tree. Zinc (Zn) is an important nutrient for pecans and can be supplied through pecan tree fertilizer. The best method to furnish zinc is a foliar spray with chelated forms that are better absorbed than the common zinc sulfate.
A yearly application of the pecan tree fertilizer which contains proper nutrients will help ensure both an abundant crop and a high quality one. Achieving the right level of P, K and Zn in soil is important for pecan production. Getting these levels up early on in young orchards by making a broadcast application of suitable fertilizer for pecan tree way to get them there. For established orchards, a soil test should be done to determine deficiencies and provide appropriate amounts of nutrients for correcting them.
Pecan trees embody resilience and productivity, with some living for 300 years and producing bountiful harvests of rich, buttery nuts. Like all trees, pecans have substantial nutrient requirements and need to be fed properly throughout their lifespan. Selecting the right fertilizer and timing can help growers optimize orchard health and performance.
Nitrogen is critical for pecans as it influences leaf development and chlorophyll production, directly impacting photosynthesis and energy availability for nut maturation. Phosphorus plays a key role in root development and energy transfer processes, while potassium contributes to water regulation, disease resistance, and structural integrity.
Incorporate a soil test prior to planting to determine specific nutrient needs. Once planted, use a pecan tree fertilizer at a general rate of 1 pound of 10-10-10 per year for non-bearing trees and 4 pounds of 10-10-10 per inch of trunk diameter in bearing trees. Apply these rates in late February or early March.
Integrating soil moisture monitoring in the orchard can further enhance nutrient uptake and efficiency. Leaf tissue analysis midsummer can also offer insights into actual nutrient uptake, fine-tuning fertilization practices in future years. Taking these proactive steps can help orchard managers keep nutrient levels within recommended sufficiency ranges and avoid over-fertilizing, which can harm tree health.
Zinc is a key nutrient in the plant, as it promotes enzyme activity, helps form chlorophyll and aids in carbohydrate metabolism. It also plays a role in regulating pecan tree growth and development, as well as nut yield. Because of this, it is essential to fertilize with zinc-rich pecan tree fertilizer at the appropriate time. The best way to achieve this is with a spray application of zinc sulfate. When using this, select a product that is formulated specifically for pecan trees and spray in early spring, before pecan buds begin to break.
When spraying, be sure to do so in the morning to avoid burning the leaves. Spray until the foliage is wet and begins to drip. Additional applications can be made every two to three weeks throughout the growing season.
implemented a targeted zinc fertilization program using zinc sulfate spray, resulting in a 25% increase in nut yield for pecan trees.

Utilized pecan-specific zinc products for precise regulation of tree growth and development.
Conducted regular zinc spray applications every two to three weeks during the growing season, maintaining optimal nutrient levels for improved nut yield.
Potassium
Pecan trees produce nuts on a 2-year cycle and require potassium for leaf growth, nut development and water uptake. Soils characterized by high pH levels may prevent their root systems from accessing these nutrients. The use of a soil test is recommended to ensure that your pecan orchard receives the nutrients it needs.
Apply pecan tree fertilizer
The timing of fertilizer applications is important for optimum production. When the fertilizer is applied during the tree’s phenological stages—distinct phases of plant growth that are influenced by environmental conditions—it is more readily available to the plant.
Nitrogen applications in late winter or early spring have a positive impact on established pecan trees. In fact, nitrogen applied at this time can enhance nut production.
Soils characterized by a high concentration of salts, such as those found in New Mexico, can reduce the availability of potassium and other nutrients.Using a pecan tree fertilizer during the late dormant season will help to alleviate these deficiencies.
Typically, pecans are fertilized by broadcasting a fertilizer with nitrogen in the feeder root zone, which extends up to twice as wide as the drip line of the tree. This can be done by spreading the fertilizer by hand or with a push-type rotary spreader. It is best to apply the fertilizer in late winter or early spring so that it is absorbed by irrigation water and carried down into the feeder roots.
