This research was aimed to study soil physico-chemical properties at four slope positions under oil palm plantation in Dharmasraya, West Sumatra, Indonesia. Soils were sampled at 0-20 cm soil depth from 4 different slope positions (upper, middle, lower slope, and the bottom or flat area). The parameters analyzed were soil texture, SOM, bulk density, total pore, hydraulic conductivity, soil water potential (physical characteristics) as well as soil pH, CEC, Al-exchangeable, basic cations (Ca, Mg, K), N, and P (chemical characteristics). The results showed that the bottom area had better soil physicochemical properties than the others. SOM increased by 33%, total pore by 19%, void ratio by 47%, plant available water (PAW) by 28%, soil pH-H2O by 41%, CEC by 171 %, total-N by 170 %, and P-potential by 114 %, in contrast, soil BD and exchangeable-Al were lower (20 % and 96 %, respectively) in the bottom than in the sloping land. The middle slope had the poorest soil physico-chemical properties after 26 years of forest conversion into oil palm plantation. All sites had clay texture, the clay content increased (R2=0.93) by lowering slope position, and so did SOM content (R2=0.86), soil CEC (R2=0.93), and soil total-N values (R2=0.76).

The high demand for soybeans cannot yet be met by domestic production. Thus, a way to increase soybean production is necessary, one of which is to use liquid organic fertilizer derived from landfill leachate. This study aimed to examine the application method of liquid organic fertilizer (LOF) from landfill leachate to the soil and leaves and to determine the concentration giving the best growth and yield of soybean plants. The study was a field-research arranged in a completely randomized design (CRD) consisting of six treatments and four replications, which was carried out in a greenhouse. The treatments include A (0 LOF/L water), B (20 ml LOF/L water), C (30 ml LOF/L water, D (40 ml LOF/L water), E (50 ml LOF/L water) and F (60 ml LOF/L water). The liquid organic fertilizer was applied through the soil and leaves at a dose according to the treatments. Â The results showed that the application of liquid organic fertilizer from landfill leachate was better applied to the soil than to the leaves. The liquid organic fertilizer given had a significant effect on the leaf area (cm2), crop weight (g), and plant seed weight (g), but not on the plant height (cm) and stem diameter (cm). Liquid organic fertilizer application is better given to the soil than to the leaves based on the independent T test. The liquid organic fertilizer from landfill leachate at a concentration of 40 ml/L of water had the best effect on the growth and yield of soybean plants.

Intensive deforestration for the purpose of agricultural field and transmigration area has happened lately in Dharmasraya Regency, West Sumatra. Land use change from forest into dry land farming, mixed trees and oil palm plantation, as well as rubber plantation has caused different level of soil fertility as a consequence of ecology changes of the areas. The objectives of this research were to identify the change of soil organic matter content, plant nutrition level, as well as bulk density of the soils at each land use. This research was conducted in Sungai Rumbai, Dharmasraya Regency in 2007. Soil samples were taken from 5 land use, those were dryland farming, mixed trees, oil palm plantation, rubber plantation, and natural forest. The soil samples, then, were analysed for the soil organic matter content (%), N-, P-, and K-content, as well as bulk density (BV) in soil laboratory, Agricultural Faculty, Andalas University Padang. The result showed that land use change from forest ecosystem into other ecosystems had decreased soil fertility level. This was reflected by the decreasing soil organic matter content, increasing soil bulk density. Nutrient status of the soil also decreased, especially potassium (K) level. Compared to the forest ecosystem, soil organic matter decreased by 13, 26, 33, and 36% respectively for dry land farming, mixed trees and oil palm plantation, as well as rubber plantation. Soil bulk density of the land use which was still close to soil under forest ecosystem (0.83 gcm-3) was found in rubber plantation (1.00 gcm-3), then followed by mixed trees (1.11 gcm-3). Potassium level of the land uses which were close to forest ecosystem (0.44 me/100g) was in rubber plantation (0,33 me/100 g), as well as in oil palm plantation(0,34 me/100 g). Based on the results above, it can be concluded that rubber and oil palm plantation was types of land use having better soil ecology compared to the other land use.

This research was aimed to evaluate fertility level of soils under different oil palm ages and the management system. This was needed to determine when oil palm and the cover crops could give the best performance in protecting soil fertility level. Lan use types studied were divided into six groups. Those were A = palm oil plantation having cover crops at 3 years old, B = palm oil plantation having cover crops at 6 years old, C = palm oil plantation without having cover crops at 6 years old, D = palm oil plantation having cover crops at 8 years old, E = palm oil plantation without having cover crops at 8 years old, F = forest ecosystem. The result showed that based on the soil bulk volume (BV) and the soil organic matter content, deforestration for oil palm plantation did not significantly decrease soil fertility status. Soil fertility level under palm oil plantation having cover crops was better than that under palm oil plantation having no cover crops. The highest soil fertility level among the land use tested was found under palm oil plantation having cover crops at six ears old. This was proved by OC content (2.21%), N, P, K content (0.12 %, 23.92 ppm dan 0.325 me/100 g, respectively) which were comparable those of forest land use. Forest had OC = 2.31 %, N = 0.11 %, P = 17.86 ppm, and K = dan 0,33 me/100 g. While, on the other hand, the bulk volume was 1.01 g/cm3 which was lower than that under other oil palm plantation.
