El estudio de la vegetación en áreas dedicadas al frijol tapado

摘要: The frequency, dominance, percentage of leaf cover and index frequency x annual perennial species were evaluated, in areas dedicated to slash/mulch bean (frijol tapado) over 35-and 80- years periods with falIow forone three years, Guaitil Acosta, Costa Rica. Soil nutrient available, their relationship plant foliar content each especies also evaluated. Under dominant. one year without pasturing, Rottboellia cochinchinensis was dominant, but, Sida rhombifolia predominated. Percentage some well correlated soil but its potential use as indicator fertility unclear. High levels the foliage suggests thepossibility weed a temporal storage nutrient, eventualIy released back be used by crop plants when is cut.
