probably fallen leaves of guadua are contributing to improve it. With the results obtained it is not possible make<br />
general conclusions because there is a high natural variability associated to variables assessed. This variability<br />
can not be explained simply with the effect of covers, therefore is only feasible to elucidate trends. In this sense,<br />
to improve the basic information could be an interesting task for further research.<br />
