    Abstract
    Charges against oil palm plantations as the cause of soil degradation and as a ringleader of environmental damage, drought land and take nutrients in large quantities makes this study important. The purpose of this study to determine the effect of oil palm cultivation on the four generation of sustainable planting to changes in soil characteristics Typic hapludults. Description of soil profiles and sampling was conducted at four sites representing generations of planting oil palm. As the control mixed crop that has not been planted with oil palm. Soil samples tested in the laboratory for each of the characteristics of soil physics, soil chemistry and microbial soil total. Results showed oil palm cultivation in soil Typic hapludults for four generations of plants continuously unchanged physical characteristics significant level. Increase soil porosity, not decreasing C-organic significantly. Saturation of Al decreased significantly and total soil microbial increased significantly. This shows that the cultivation of oil palm trees in a sustainable manner with the best management practise systems PT Socfindo can maintain soil fertility.
     
    Tuduhan terhadap perkebunan kelapa sawit sebagai penyebab degradasi tanah, kerusakan lingkungan, kekeringan dan sebagai tanaman mengambil hara tanah dalam jumlah yang besar menjadikan penelitian ini penting. Tujuan dari penelitian ini untuk mengetahui pengaruh budidaya tanaman kelapa sawit pada empat generasi tanam yang berkelanjutan terhadap perubahan karakteristik tanah Typic hapludults. Deskripsi profil tanah dan pengambilan sampel dilakukan di empat lokasi yang mewakili generasi tanam kelapa sawit. Sebagai kontrol adalah kebun campuran yang belum pernah ditanam kelapa sawit. Sampel tanah diuji di laboratorium untuk masing-masing karakteristik fisika tanah, kimia tanah dan total mikrobia tanah. Hasil menunjukkan budidaya kelapa sawit di tanah Typic hapludults selama empat generasi tanam secara terus menerus tidak mengalami perubahan karakteristik fisika tanah yang signifikan. Meningkatkan porositas tanah, tidak mengalami penurunan C-organik tanah secara signifikan. Kejenuhan Al mengalami penurunan yang signifikan dan total mikrobia tanah meningkat secara signifikan. Ini menunjukkan bahwa budidaya tanaman kelapa sawit secara berkelanjutan dengan sistem manajemen praktis terbaik PT Socfindo dapat mempertahankan kesuburan tanah.
