Interference interactions in experimental pine-hardwood stands
… and other interference from non-crop vegetation often limits the productivity of pine and pine-hardwood forest stands in the southern United States. However, forest researchers have yet to fully quantify the effect of this interference on forest tree yield and there is an incomplete understanding …

Long-term Effects of Fertilization on Phosphorus Biogeochemical Pools in Forest Soils
Southern pines are typically limited by nitrogen (N) and phosphorus (P) availability in the soil environment. While the absolute quantities of P in forests soils may be large, the concentration of inorganic P in the soil solution is typically very small (< 0.01 mg L²-1). A onetime application of …
