Temporal Variation in Nutrient Element Losses in Fallows of Different Ages Southern Nigeria
Anthony Iwara and Olakunle Ogundele

Background and Objective: Understanding on the amount of nutrient element loss in vegetation fallows of varying ages particularly the temporal variation (monthly) is was not adequately documented in the literature. The study examined monthly nutrient loss in 10, 5, and 3 year old fallows in a part of the rainforest zone in southern Nigeria. Materials and Methods: Three runoff plots of 10×4 m were constructed in each fallow community and used to collect sediment from which nutrient loss was estimated using standard laboratory procedures. Results: Results obtained showed that the months of June, July, August and September yielded high nutrient losses on all the plots with September recorded the highest nutrients losses followed by August. High nutrient losses on the 10 year old fallow plot occurred in August; July on the 5 year fallow and September on the 3 year fallow plot. The amount of nutrient losses varied significantly among the plots (p<0.05). The order of nutrient loss for the study revealed the order: OC>Ca>TN>Mg>Na>P>K. Conclusion: The result revealed that substantial amount of nutrients was lost in sediment on fallow lands and that nutrient element losses decreased with increasing herbaceous cover.
