Boost Your Citrus Crop: Expert Tips on Micronutrient Management

John cites a phosphorus tissue result of 0.13% against a citrus range of 0.12 to 0.17.

1. Yara's Crop Nutrition podcast on "Boost Your Citrus Crop: Expert Tips on Micronutrient Management" focuses on micronutrient management for citrus in California's Central Valley. 2. Scott Warr hosts, John Martin joins as a seasoned citrus grower from Reedley, California, and Vanessa Dominguez appears as Yara's sales agronomist. 3. The episode asks how citrus growers can replace a "shotgun approach" with tissue-based nutrition decisions that support yield, quality, and tree health. 4. John says micronutrients support plant growth, energy cycles, chlorophyll development, and the basic building blocks of cells. 5. He says earlier citrus practice often meant applying zinc, iron, and manganese routinely without knowing whether the tree needed more or less. 6. John names cobalt, nickel, and molybdenum as micronutrients that have received more attention in the field over the last 20 years. 7. Vanessa says tissue sampling and lab analysis help growers avoid guessing and show what is actually in the tree. 8. She says a tissue analysis gives a "snapshot" of nutrient levels and helps tailor crop programs when one nutrient, such as zinc, is already high. 9. John warns that over-applying micronutrients can cause toxicity and create imbalance that affects the use of other nutrients. 10. He connects nutrient balance to saving money by applying only what the plant needs instead of paying for unnecessary products. 11. John says trees in heat stress need to be in a balanced nutrient state, and he compares that to the way a healthy plant better handles disease pressure. 12. He cites huanglongbing, or citrus greening, as an example where higher and better-balanced nutrition helps trees cope because the disease plugs nutrient pathways. 13. John says older tissue sampling was often used only once a year or only after a visible field problem appeared. 14. He says progressive growers now treat regular tissue sampling as an integral part of the program rather than a one-off diagnostic tool. 15. Vanessa says she recommends at least two samples per season and notes that some growers pull two or three samples during a growth stage. 16. She also says her tomato trials use samples after fertilizer applications to track how nutrients move after three to six days. 17. John says tissue reports are usually interpreted against UC standards, but variety differences mean experience still matters. 18. He describes a team approach that includes the grower, a PCA, a CCA, and sometimes a manufacturer representative when interpreting results. 19. Listeners who manage citrus, work with tissue sampling, or advise on micronutrients will get practical field guidance. 20. Listeners wanting a broad farm-management discussion without citrus-specific sampling detail may skip it.

As heard by us

A practical citrus nutrition conversation that turns sampling into a money-and-yield decision.

The discussion stays on citrus micronutrients, deficiency symptoms, and why regular tissue sampling can sharpen fertilizer decisions. John Martin and Vanessa Dominguez keep it practical.
