Relatively few of the agronomic basics are known about the Peach Palm that woud permit its rational exploitation. Amoung these aspects a knowledge of the root distribuition is essential for the planning of production systems. In this study the authors used an auger sampling method to sample the root system of 7 peach palm trees with two to nine trunks per tree. The samples were separated, washed, dryed and weighed, in order to characterize the root distribution in a Yellow Latosol, with medium texture and an Ap horizon. 58% of the weight of all the samples was found to occur in the first 20 cm of the soil, with 53% (48% individual crown) of the total weight found in this layer and within the area of the crown diameter. It was also found that 89% (82% individual crown) of the total weight occured within the crown diameter to a depth of 200 cm. |
