dc.description.abstract | Generally, the kind of soil is Typic Pale
which contain Carbon (C) classified is average for upper stratum and low for lower stratum. The contain of Nitrogen (N) is rather low for or stratum, and also Fosfor (P) is low, and its soil pH is acid. The actual compatibility class on this soil can be increase become S2 (appropriate). Despite the effort of fertili
IOPRI Medan have been done to actulaize the production potential accordance with prodaction standard of soil class, but the prodaction which expected are not reached. The phenomena appears questios that required a study, where it is expected could be axplain the obstruction and improvement efforts that could be done possibly to be consideration and escalation of plam oil production. To finish the problems, we need to done a

reaction soil pH is classified very low to low (4.2 – 5.5), C/N is very low to average (0.17-9.4), contain of P is average to high (18.25 - 56.68 ppm), Kation Ca+2 is very low to low (1.22 – 4.88 me/100g), K+ is very low to low (0.12 – 0.31 me/100g). KTK is average (12.5 - 23.6 me/100g), KB is very low to low (10.7 – 69.0 % ), soil texsture whit high clay fraction, BD and PD is high relative. Soil physical characteristic shows soil texture in the

Individually C/N and KTK soil of Typic Paleudult at Kwala Sawit Estate repress the bunch production per tree of palm oil. Physical and chemistry characteristic of soil together determine the bun

Estate, PT. Perkebunan Nusantara II is under production average according to productions standard based on soil class average in one cycle ( 25 years) is 9.9 bunches per tree and its realization is per tree. | en_US |
dc.description.abstract | Secara umum jenis tanah yang terdapat di Keb
Paleudult yang mengandung Karbon (C) tergolong sedang di lapisan atas dan tergolong rendah dilapisan bawah. Kandungan Nitrogen (N) agak rendah pada seluruh lapisan, begitu juga Fosfor (P) tergolong rendah, pH tanahnya masam, Kapasitas Tukar Kation dan Kejenuhan Basa tergolong rendah di seluruh lapisan. Kelas kesesuaian aktual pada tanah ini adalah S3 (agak sesuai), tetapi dengan perbaikan faktor pembatas tersebut kesesuaian lahan dapat ditingkatkan menjadi S2 (sesuai). M
an untuk mengaktualisasikan potensi produksi sesuai dengan standar produksi kelas lahan, tetapi produksi yang diharapkan tidak tercapai. Fenomena ini menimbulkan pertanyaan yang memerlukan kajian yang diharapkan dapat menjelaskan hambatan dan upaya perbaikan yang mungkin dapat dilakukan untuk menjadi pertimbangan dalam peningkatan produksi kelapa sawit. Untuk memecahkan masalah tersebut perlu dilakukan su
an untuk mengkaji sejauh mana sifat fisik dan kimia tanah Typic Paleudult hubungannya dengan produksi kelapa sawit di Kebun Kwala Sawit PTPN II. Parameter yang diamati adalah mencakup sifat kimia (pH, C/N, P ters
tukar, Ca tukar, Mg tukar, Na tukar, KTK dan Kejenuhan Basa), sifat fisik (Tekstur tanah, Bulk Density, Partikle Density dan Total Ruang Pori) Hasil penelitian sifat kimia dan sifat fisik tanah
tanah tergolong sangat rendah sampai rendah (4.2–5.5), C/N tergolong sangat rendah sampai sedang (0.17 – 9.4), kandungan P tergolong sedang sampai tinggi (18.25 – 56.68 ppm), Kation Ca+2 tergolong sangat rendah sampai rendah (1.22l–4.88 me/100 g), Mg+2 tergolong tinggi sampai sangat tinggi (0.84 – 3.35 me/100 g), Na+ tergolong rendah sampai sedang (0.22 – 0.48 me/100 g), dan K+ tergolong sangat rendah sampai rendah (0.12 – 0.31 me/100 g). KTK tergolong sedang (12.50 – 23.60 me/100g), KB tergolong sangat rendah sampai rendah (10.70 – 69.03 %), tekstur tanah dengan fraksi liat tinggi,nilai BD dan PD relatif tinggi. Sifat fisik tanah menunjukkan tekstur tanah di lokas
engan kandungani liat tinggi. Fraksi Liat, Pasir, BD, PD dan TRP masing-masing menekan produksi tandan per pokok kelapa sawit. Karekteristik sifat kimia tanah C/N dan KTK pada tanah Typic Paleudult di kebun Kwala Sawit masing-masing menekan produksi tandan per pokok kelapa sawit.K
ukan produksi tandan per pokok kelapa sawit adalah C/N, P tersedia, Na tukar, Bulk Density dan Total Ruang Pori. Produksi tandan per pokok k
PTPN II dibawah rata-rata produksi menurut standart produksi berdasarkan kelas lahan rata-rata satu siklus (25 tahun) adalah 9.9 tandan per pokok, realisasinya adalah 6.1–6.5 tandan per pokok | en_US |
