The objective of this research was understanding the impact of planting method to N and P element in the soil (swapt away by erosion) of aslant land, determining the best planting method and plant variety that has best ability to reduce erosion of N and P element. This research employed erosion block for seasonal plants with 30O of declivity. Erosion of N and P element examined by analyzing the soil swept away by erotion every 5 days. Analysis of N and P element included available N, total N, available P and total P. Then the data was analyzed with T-test at 95% level confidence.

Conclusion taken from this research were: 1) Planting method reduce availble P and total P element, respectively as much as 15% and 20%, but there was no significant difference between available N and total P, 2) There was significant difference between available P and total P, when the variety of plant and combination was employed as a treatment variation, 3) Pennisetum purpureum planted by using equidistant method reduce N and P element in the soil, respectively as much as 15% and 20%.
