Effects of past agricultural practices on the soilphosphorus system and growth of planted pines1
1981
GILMORE, A. R. | MATIS, D. S.
Past agricultural practices affected the aluminum, iron, and calcium fractions of soil phosphorus. Liming caused the greatest change in the fertilizer phosphorus, but had little effect on the native phosphorus. Soil acidity increased after the trees were planted, which was attributed primarily to the action of the acid tree litter. Foliar phosphorus was not related to past agronomic practices and was greater than levels shown to be limiting for pine growth. The study demonstrated the importance of plant species to nutrient uptake and growth.
