Observations of soil conservation are carried out using qualitative method with descriptive, wwhere field activities include observations of vegetatif method, mechanic method and chemical method. Oil Palm plantation of PT. Citra Putra Kebun Asri uses 2 soil conservation methods, that is vegetative and mechanical methods. Vegetative method is carried out by utilizing litter (mulching), namely by arranging the oil palm fronds of prunning result in dead gawns with the aim of supressing growth of weeds and prevent erosion. Mechanical method is done by applying trenches and rorak. Trenches just made in low areas with the aim of being a drainage channel for block are not inundated and making rorak as a shelter for crop residues in the dry season to keep it moist.
土壤保持观测采用定性和描述性相结合的方法进行，其中实地观测包括植被法、力学法和化学法。PT. Citra Putra Kebun Asri油棕种植园采用两种土壤保持方法，即植物法和机械法。营养法是利用凋落物(覆盖物)，即将修剪后的油棕叶布置成枯枝，以抑制杂草生长，防止侵蚀。机械法是用沟槽和耙子进行的。在低洼地区挖的沟渠，目的是作为街区的排水通道，而不是被淹没，在旱季，它可以作为农作物残留物的庇护所，保持潮湿。
