Effect of Tillage and mulching on soil water erosion in Linsinlin watershed, Centre of Benin
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
Soils degradation in Benin is most commonly reported thread for the agricultural production and this situation became more crucial in the Centre of Benin. This study has been carried out to evaluate the contribution of farmer’s soil conservation practices to combat soil erosion in the agricultural watershed of Linsinlin. A field experiment was conducted on loamy-sand soil using Fisher Block design under researcher management. The factors which testified during study were tillage and mulching. The “Runoff plot” system was installed to collect erosion data. Three rainfall episodes viz, June 15, 19 and 27, 2016 with 52, 27 and 57 mm of water were used for the data collection. Rain distribution was measured for each rainy episode using a rain gauge. These three rainy episodes constitute a repetition. Results of study revealed that tillage and mulching treatment significantly decrease runoff, soil loss and nutrients loss (nitrogen, available phosphorus, potassium, magnesium). In case of nutrient lose, highest amount of nitrogen and potassium were lost. The interactive effect of tillage system and mulching was significant on runoff, soil and nutrient loss. The treatment combining isohypse ridging with mulching practice reduced total runoff from 6.27% to 0%, soil loss 2028 kg.ha-1. rain-1 to 0 kg. ha-1.rain-1and nutrient loss (from 4.32 kg. rain-1to 0 kg. rain-1for total nitrogen, from 0.17 kg.rain-1to 0 kg.rain-1for available phosphorus, from 4.38 kg.rain-1 to 0 kg.rain-1 for potassium, from 3.32 kg.rain-1 to 0 kg.rain-1 for magnesium). Particulate organic matter, clay and sand fraction were more lost through water erosion on the watershed of Linsinlin.
