Soil and Tissue Nutrients, Soil Drainage, Fertilization and Tree Growth as Related to Fusiform Rust Incidence in Slash Pine
Abstract:The relationships between fusiform rust incidence and fertilization, soil properties and associated tree growth in 25 uniform fertilizer tests with slash pine were studied 5 years after establishment. The tests were located on representative forest soil types of the Lower Coastal Plain of the southern United States. Rust incidence averaged 35.3 percent and ranged from 0 to 86.0 percent. Analysis of the combined data indicated that rust incidence and tree height increased with the addition of fertilizer but that these increases were not statistically significant. Significant differences in rust incidence and tree height occurred among soil drainage classes. Rust incidence was lowest on poorly drained soils, intermediate on moderately drained soils, and highest on well-drained soils. Rust incidence in unfertilized treatments was directly correlated with extractable soil P and foliar P and inversely related to total soil N. With separation into soil drainage classes 9 tests showed an increase in rust with added N (N-rust-responsive tests) and 8 tests showed an increase in rust with added P (P-rust-responsive tests). Comparison of soil and foliar N and P indicated that prior to fertilization N-rust-responsive tests were relatively low in soil and foliar N, and P-rust-responsive tests were relatively low in soil and foliar P.
