Ecology of a rice fallow vegetation under lowland traditional farming in the dry zone of Sri Lanka



Ecology of a rice fallow vegetation under lowland traditional farming in the dry zone of Sri Lanka



Tropical Ecology 33(1): 17-28



Floristic change and biomass dynamics were monitored during a fallow period in a rice field of traditional farming system in the dry zone of Sri Lanka, for a period of twenty months. Herbage intake and cowdung dropped by cattle were also estimated during the peak period of grazing. The initial fallow flora was dominated by annuals, which were replaced thereafter by perennials. This floristic change accompanied a decline in species richness and also caused a fluctuation in the number and degree of interactions between species. The sequence of domination of groups of plants along the fallow period was sedges, grasses and then legumes. During the fallow period there was a net negative effect on soil fertility in terms of N, P and K dynamics through grazing and dropping. However, the accumulation of plant litter and cowdung during this period may have promoted soil biological activities, thus maintaining fertility.
