Abstract

Research on the effect of organic mulch and earthworms under oil palm plantation on the total population bacteria is still scarce. The study aims to analyze the effect of organich mulch, earthworm desity, and the interaction between organich mulch and earthworm density on the total population bacteria. The research was carried out in May – August 2019. This research was a 3 x 4 factorial experiment which was placed according to a Split Plot Design with the basic design of Randomized Block Design, each treatment was repeated 3 times. Organic mulch as the main plot are 3 type, namely: M1 (M. bracteata), M2 (oil palm empty fruit brunches/ OPEFB) and M3 (oil palm midrib). The density of earthworms as subplots consists of 4 levels, namely: C0 (0 worms/m2), C1 (35 worms/m2), C2 (50 worms/m2) and C3 (65 worms/m2). The data were analyzed using analysis of variance. If the treatment is significantly different, the treatment was tested by Duncan’s at 5% significance level. The results showed that oil palm midrib organic mulch can increase the total population of fungi and bacteria compared to M. bracteata and OPFEB. The earthworms density 50 and 65 worms/m2 can increase the total bacterial population compared to other earthworm densities. The combination of oil palm midrib with earthworms density 50 and 65 worms/m2 can increase the total population of bacteria

Abstract

Planting of oil palm in peatland has been limited by soil physical, chemical properties, and hydrology, that`s way needed improvement on those matters to increase the productivity of peat and oil palm in peat soil by compacting. The purpose of this compacting is to improve the soil's physical, chemical properties, and soil moisture. A sampling of soil, water, and leaf were done in consecutive block 5,4,3,2,1,0 year after compacting and of planting done 4 years 10 months, 3 years 9 months, 2 years 9 months, 1 year 10 months, 11 months and 2 months, control used in this trial are origin condition (forest). Increasing bulk density was found at compacting block with 30 cm depth from the surface with the lower in 2 years after compacting at 0.09 g/cm3 and highest 4 years after compacting 0.4 g/cm3. In-depth of 60 cm from surface was found no increasing the bulk density 3 years after compacting 0.0 g/cm3 and the highest on 5 years after compacting 0.3 g/cm3 compared to forest. Decreasing on permeability in-depth 30 cm at 4 years after compacting 7.47 cm/jam and close to forest permeability 51.11 cm/hour is 2 years 43.6 cm/hour. As represent rise capillary consistently water content ≥ 80% achieved at depth 20 cm of surfaces on all block. Compaction doesn't regard pH, C organic, basa's saturation, capacity exchange cation. On depth 30 cm P-total lower on s without compaction at 599.6 ppm and above 871.6 ppm on 5 yr than forest 585 ppm. P available most low 58.1 ppm happens on 4 yr afters is compacted and p available forest 53.9 ppm. Nutrient content B, Cu and Zn at soil not influenced by compaction. Fosfor (P) in water increases with added years after compaction lower at 39.1 mg/L in the block without compaction compare of forest that 40.8 mg/L.

Abstract

The aim of this research was to studied the nature of soil chemistry and growth of agarwood (Aquilaria malaccensis) as an intercropping plant in palm oil land plantations that applied EFBPO compost and biochar. The study was conducted in Bukit Kemuning from May 2018 to December 2019. This study used randomized block design. The treatment is applied EFBPO compost and biochar with 7 levels, namely : without EFBPO compost and biochar, gived 0.5 kg EFBPO compost per a plant, gived 0.5 kg EFBPO biochar per a plant, mixed at dose 0.25 kg EFBPO compost and 0.25 kg EFBPO biochar per a plant, gived 1 kg EFBPO compost per a plant, gived 1 kg EFBPO biochar per a plant, mixed at dose 0.5 kg EFBPO compost and 0.5 kg EFBPO biochar per a plant. Each treetment was repeated 3 times. The observed parameters were soil chemical properties, chlorophyll content, plant height, number of branches, diameter of the stem and leaf area. The results showed that the provision of EFBPO compost or biochar at dose of 0.5 kg or 1 kg per a plant and mixed both at a dose of 0.25 kg and 0.25 kg or 0.5 kg and 0.5 kg per a plant to increase Organic C, P total, K total, KTK and decrease Al dd each 61.83%-102%, 17.18%, 28.04%-64.09%, 23.98% and 14.29%-57.14% compared to control. It also increases plant growth, such as increases plant height, number of branches, diameter of the stem, and leaf area, each 0.67%-56.72%, 5.50%-22.17%, 7.69%-52.88% and 5.73%-125% compared to control.

Abstract

Utilization of peat as agricultural land faced the problem of low soil fertility. Low soil fertility made nitrogen being leached easily. One solution to overcome Nitrogen leaching and efficiency fertilizer raising used dolomite and slow decompose fertilizers. This study aims to determine the effect of dolomite on Nitrogen element leaching in several types of NPK slow decompose applied for corn cultivation in peatland and determine the best dolomite dosage and NPK slow decompose with minimum Nitrogen leaching to optimum sweet corn plant growth in peatland. This research was conducted from August to October 2018 in the Experimental Garden Technical Implementation Unit and Soil Laboratory, Faculty of Agriculture, University of Riau. This research used experimentally and completely randomized design (CRD) factorial. The first factor is dolomite which consists of 4 levels (0 tons.ha-1, 2.5 tons.ha-1, 5 tons.ha-1, dan 7.5 tons.ha-1). The second is NPK slow decompose which consists of 4 levels (NPK single pearl, NPK 13: 6: 27: 4 + 0,65B Mahkota B, NPK 13: 6: 27: 4 + 0,65B Compound Plus Hi-Kay and NPK 13: 8: 27: 4 MgO Ztick). The results showed the administration of dolomite 23.55 g per tube and NPK slow decomposed could reduce Nitrogen leaching, improve physiology and growth of sweet corn plants. Provision of interaction between dolomite 5 ton.ha-1 with NPK slow decomposition (30.25 N, 3.72 P, 12.56 g per tube) produces the best interaction that can reduce the proportion of Nitrogen leaching and it can affects the increasing of plant growth.

Abstract

Oil palm cultivation is generally carried out in monoculture. This has an impact on decreasing soil fertility, one of which is the physical properties of the soil. One of solutions that can be done to overcome this is the cultivation of oil palm plants with an agroforestry system. The purpose of this research was to compare the physical properties of soil agroforestry on oil palm (Elaeis gueneensis Jacq.) and aloes (Aquilaria malacensis Lamk.) with oil palm in monoculture. This research was conducted in Bukit Kemuning Village, Tapung Hulu District, Kampar Regency for 4 months from November – Februari 2020. Determination research the locations for agroforestry system and monoculture system using purposive sampling method. Soil samples were taken from 4 sampling point: palm circle, leaf frond piles, harvest path and aloes circle which were repeated 6 times on each land. The observation parameters are several soil physical properties (topsoil depth, bulk density, particle density, total pore space, moisture content, water holding capacity, permeability, infiltration, and soil resistance) and soil C-organic. Data from the observations of each parameter were analyzed statistically using the t test. The results showed that the agroforestry system increased C-organic content and improved selected soil physical properties (increase topsoil depth, total pore space, moisture content, water holding capacity, permeability, infiltration and decrease bulk density, particle density and soil resistance).

Abstract

Macrofauna data on post-fire peat soils have been documented in many literatures, but assessments of soil macrofauna recovery in peatlands after one and a half years after fires are scarce. The aim of this study was to evaluate the recovery of soil macrofauna in peatlands after one and a half years after fires. This research was conducted on peat land in PT.SSS Kuala Panduk Teluk Meranti District, Pelalawan Regency. This research was conducted by survey method. Determination of the location using the purposive sampling method, especially on peatlands after one and a half years after the fire and unburned peatlands. Based on peatland cover, 6 samples were taken, and 6 samples were taken from unburned peatland. Determination of the sampling point using a systematic method. Macrofauna observations included number of families, number of individuals, population density, and diversity index. The study of macrofauna recovery was carried out by t-test on macrofauna data on peatland fires and unburned peatlands. The results shown in peatlands after a year and a half of fires are macrofauna recovery.
