Foliar nutrient contents of tropical tree species under different management and climate conditions

Plant species, regional conditions and management practices haveeffects on plant nutrient uptake; however, its study is complex as their effects occur all at the same time. This compares foliar contents of Brosimum alicastrum (evergreen), Cordia dodecandra (deciduous), Spondias purpurea (deciduous) tree individuals growing in homegardens forest two climate regions. 20 per species associated soils were sampled. Soil pH, electrical conductivity, sand, silt, clay percentages, well edaphic C, N, P, K, Na, Ca analyzed. Nutrient levels with each significantly different (λ Wilks = 0.61, F12,372 8.70; p < 0.0001). Forest had higher C N; homegarden more silt phosphorus. The three 0.11, F12,458 77.71; P B. greater Na K; C. Ca, S. N P. Foliar content was times trees than individuals. Our results suggest that primarily determines content; depend region; both, determine contents.
