The sampel from land that has beenplanted with LCC are analyzed in Soil and Water at Agricultural Polytechnic state Samarinda.The result analysis isN content at t0 is 0,067 %; at t1 is 0,025% and at t2 is 0,017%. That is shows that total N on the soil after plantingtwo LCC is lower than the total N on the land where LCC is no planted, whereas the total N at t1 is almost equalto the total N at t2.]]>
