The soil loss was assessed during a period of seven months. The sediments collected in the tank have been dried and weighted daily to estimate soil loss (erosion) per each treatment. Precipitation has been also measured every day in a conventional rain-gauge. Variance analyses have been conducted to determine statistical differences in soil loss among the treatments evaluated. The post ANOVA test of Tukey was performed to determine differences among means. Erosion was lower under treatment with guadua with 0.11 Tn ha -1 per seven months. Whereas soil loss in the treatments with crops was strikingly high with 0.26 Tn ha -1 per seven months. It is important to remark that the only treatment with significant (P
Conclusions and recommendations Forest mensuration methods are adequate for determining the growth pattern and the explicit dendrometric and stand characteristics of guadua. Though these methods should be applied considering adjustments that depend on specific features of this bamboo resource. Thus information from inventories will be reliable and useful for making decisions. For determining the effect of site conditions on guadua is necessary to define previously which variables could be used to evaluate the response to factors associated to site. In this sense predictive models for culm length, basal area and culm hardness show a reasonable goodness of fit and might be considered as response variables to determine the effect of environmental factors on guadua productivity and quality. Thus, average culm length and stand basal area can serve as indices of guadua stand productivity. Whereas average culm hardness is useful to determine culm quality within guadua stands. Although, the variability in productivity and quality of guadua could not be entirely described by the environmental set of independent variables measured, these results are a significant contribution to know on the potential use of this natural resource in the coffee region of Colombia. Combining harvest intensity and frequency is possible for establishing the best level of silvicultural management, maintaining as a reference an adequate number culms per ha. For guadua plantation the fertilisation of Guadua and the reduction of interspecific competition with herbicides, represent high possibilities to increase the yield within guadua plantation. Nevertheless, now is required to study in detail this topic which has been barely studied for guadua. The implemented model for forest planning was useful to define land capability and also units of forest management. Nowadays, government institutions can lead the planning of guadua stands based on this model. Besides, the units of forest management are an alternative against drawbacks relate to fragmented pattern of guadua stands. Even though guadua bamboo forest in the coffee region of Colombia are highly fragmented, they fulfill important ecosystems functions and provide environmental services such carbon sequestration and soil protection that contribute to maintain the stability even within transformed areas (agroecosystems). Hence strategies for ecosystems conservation or an adequate management of these forests should be implemented, given that are almost the latter remnants of forest cover in this significant area of Colombia. Ecosystems functions and environmental services are provided by guadua bamboo forest even under harvesting. Thus some incomes and products are directly perceived by farmers and certainly, it could motive them to maintain areas under guadua forest within their farms. Thus it would be an strategy that could contribute to the sustainable development of rural areas upon the base of integrating production and conservation.
