The objective of this research was to evaluate and assess the level of run-off and erosion on various types of land use in the Upper Jenneberang Sub Watershed. This research was conducted in the Upper Jenneberang Sub Watershed, Saluttoa Village, Sub Tinggimoncong, Gowa regency, South Sulawesi Province. Land use type (LUT) which was used as land units of observations was determined based on land use maps of upper Jenneberang sub watershed. Based on the analysis results of map and observation in the field, it was defined four types of land use as land units of observation: 1) Natural forest, 2) Gliricidia tree-dominated agroforestry, 3) Coffee tree-dominated agroforestry, and 4) Maize monoculture. Each LUT was given the observation plot size 30 m x 10 m and plot placement was determined randomly. All LUT had slope 26%, soil type of Brown Latosol at the same altitude and climate. The composition of the observation plot was based on Randomized Block Design (RBD). Collected data on LUT included: soil physical properties, infiltration rate, run-off and erosion. The result showed that changes in land use of natural forests into agroforestry and maize monoculture types resulted in decreased amount of woody vegetation that resulted in increased run-off and erosion. Keywords : run-off, erosion, agroforestry

One of the things that are important to consider when fertilizing is how to place the fertilizer so that plants can consume nutrients efficiently. The research objective was to assess the precision of soil conservation based on fertilizer placement so that fertilizers could increase the production of taro effectively. This study applied four treatments, namely without fertilizer, placing manure in the planting hole, placing manure in the biopore, and placing manure on the borders. The three treatments were given 1 kg of goat manure. The treatment was performed with six replications. Harvesting is carried out in 8 months after planting. The results showed that the placement of manure on the borders was the most effective treatment with the highest yield of wet tubers of 21.4 Mg/ha and was not different from the treatment of manure in biopore 18.3 Mg/ha.This yield was different significantly as compared to that of resulted from treatments where fertilizer was placed in the planting hole (15.9 Mg/ha) or the production of taro without manure application (11.57 Mg/ha).
