Effect of Fertilization on Productivity of Second Rotation Coppice of Eucalyptus urophylla in South China

Most of fertilization trials of eucalypt plantations are for first rotation seedling plantations. There are very few reports on effect of fertilization on second rotation coppice. The study in Huadu of Guangdong Province shows that fertilization significantly increased tree height and diameter growth. But the increment decreased with time. At year 3, the effect of fertilization was significant at p=0.10. However, the best fertilization treatment increased productivity of second rotation coppice by more than 50% over the treatment without any fertilizers and fertilization increased economic benefit of second rotation coppice. Comparing with first rotation seedling plantation, effect of fertilization on second rotation coppice is lower.
