The effects of varying levels of nitrogen and phosphorus on the macro- and micronutrient content and uptake by Acacia auriculaeformis A. Cunn. Ex. Benth seedlings [Philippines]

Belen, R.E.
Acacia auricuolaeformis A. Cunn. Ex. Benth (acacia) seedlings planted in pots containing Carranglan soil were treated with factorial combinations of 0, 30, 60 and 120 kg per hectare of N and P fertilizers. Fertilizer application of 120 kg N per hectare and 30 kg P per hectare increased root dry matter yield of seedlings after six months. Other growth parameters were not significantly affected by the N and P fertilizer treatments. Application of N and P fertilizers increased pH of the soil making Fe, Mn, Cu and Zn unavailable to the plant. Nitrogen fertilization increased Mn content, reduced Cu and Zn contents, and reduced Zn and N uptake of seedlings. Phosphorus fertilization increased the total P, Mg content, P uptake and decreased the Fe, Mn, Cu content, Fe and0871 Zn upt
