Two methods of estimating fine root production and turnover are compared for 13 forest ecosystems exhibiting a wide range in form (NH vs. NO ) and quantity of available nitrogen. The two methods are by comparison of seasonal maxima and minima in biomess and by nitrogen budgeting. Both methods give s...
