Adequate soil-oxygen supplies increase nutrient concentrations in citrus seedlings
Oxygen is essential for nutrient uptake by plant roots, but little information has been available concerning the influence of soil oxygen on the nutrient concentrations in citrus. The study reported here involved sweet orange seedlings (Citrus sinensis var. Bessie). Nutrient concentrations in the tops and roots of the citrus seedlings were used as criterion to show effects of different soil-oxygen diffusion rates on citrus plants.
