Nutrient management is important for citrus production. Regular nutrient assessments should be conducted to optimize nutrient balance and prevent deficiencies or over-fertilization. Optimizing nutrition is important for tree health and can improve tolerance to stresses and diseases.

Good nutrient management requires regular field monitoring to identify problems and examine crop responses. Leaves need to be collected and sent to a specialized laboratory to get a detailed analysis of macronutrients and micronutrients, which is time-consuming and costly.

It is recommended to conduct nutrient analyses in July and August after the spring flush (seeĀ edis.ifas.ufl.edu/pdf/SS/SS53100.pdf), but more frequent analyses of leaf nutrients may be necessary to determine deficiencies associated with huanglongbing or other biotic and abiotic factors. Additional analyses may also be necessary where responses to novel management…
