Abstract

ABSTRACT
Red-yellow podzolic soil is widespread in West Kotawaringin and mostly used as agricultural land. It cause
changes in soil properties so that soil fertility analysis is needed. The research aims to study the chemistry and
physics of red-yellow podzolic, as a result of agricultural activities. The research was conducted by taking soil
samples from unmanaged land (control land) and oil palm plantations belong to KUD Tani Subur which applied
oil palm integration with cows in Pangkalan Lada, Central Kalimantan. In this study we conducted simple random
sampling method with 5 replications. Variables used as parameter in the study are porosity, bulk density, pH, Ctotal, N-total, P-available, Cation Exchange Capasity (CEC), base saturation (BS), Fe, and Al-exchangeable. The
results show oil palm plantations have soil porosity 51,84%, bulk density 1,28 g cm
-3
, pH soil about 5,02-5,04;
C-total 1,23-1,69%; N- total%; 0,06-0,11%, P-available 8,1-8,9 ppm; CEC 18,52-22,85 me 100g
-1
; BS 1,79-
3,24; Fe 0,59-0,82 ppm; and Al- exchangeable 110,46-111,29 ppm, but control land have soil porosity 45,03%;
bulk density 1,46 g cm
-3
; pH 5,04-5,13; C-total 0,76-1,05; N-total 0,09-0,19; P- available 9,3-9,7 ppm; CEC
20,30-22,27 me 100g
-1
; BS 2,33-2,76%; Fe 0,02-0,68 ppm; and Al-ec 126,67-156,60 ppm. Land use of RYP soil
types as oil palm plantations with semi- organic processing techniques does not degrade the soil, and could
increase land productivity compared to unmanaged land.
Keywords: RYP, soil chemistry and physics, different land use.
