Abstract

Soil samples taken in 1955—from a 38-year-old citrus orchard—were compared with soil samples taken in 1927 when a long-term fertility trial with various fertilizer treatments was started. The main factors known to have influenced yields in the fertility trial are available nitrogen and structural conditions of the soil. The application of phosphorus fertilizers did not influence the yields or the quality of the fruit.
