Understorey Plants

The objectives of this study was to determine soil fertility and types of plants in understorey ecosystems in oil palm plantation stand which are managed in different ways. The data collection method was a direct observation on smallholder oil palm plantation at 15 years of age with different management, namely: 1) weed control using herbicides, 2) without management, and 3) used for beef cattle grazing. The data consisted of soil fertility and identification of understorey species in each management. The soil samples were taken in a composite manner and analyzed in the laboratory, while the plant species samples were gathered using the 1x1 m2 method and identified using an identification manual. From the results, weed control in oil palm plantation with cattle grazing has a positive impact on soil fertility compared to the use of herbicides and without control. The diversity of understorey species in cattle grazing locations is less, namely, as much as 11 species compared to the use of herbicides (15 species) and without control (22 species). Weed management by grazing cows in the oil palm plantation increased land fertility and the dominance of understorey plants as a source of animal feed.

One of the strategy to overcome this problem is through the implementation of palm-cow integration system, which providing organic fertilizer. The implementation of the system is still very limited. This study aims to estimate the potential of oil palm plantations in providing of livestock feed, to identify problems, and to develop strategies for implementing oil palm-cow integrated system. The research was conducted in Paser and North Paser Penajam district in East Kalimantan Province. Data collection was conducted in 2017. The forcasting used trend analysis, the problem mapping was done by rank analysis, and the strategy formulate by descriptive approach. Based on the estimation it is known that the area of Production Plant area tend to increase and shows the available feeding ability to support the development of palm-cow integration system. In 2019 it was estimated that debris of palm frouds was 384.8 thousand tons and 41,6 thousand tons of dried leaves. This number will continue to increase 2.1 times by 2028. Utilization product from palm oil estate is still faced with various obstacles. Financing becomes a major problem in the development of cow-palm integration. In addition, the problems encountered related to the availability of land, the loss risk of livestock, and changes the culture in farming system. Strategies need to be formulated related to regulation, support facilities, and technical assistance. In terms of providing facilities and assistance, it is necessary to provide communal livestock facilities as well as assistance in developing livestock business and utilization of oil palm plantation waste.</p><p>Keywords: oil palm, integrated farming, cow, animal feed</p><p> </p><p align="center"><strong>ABSTRAK</strong></p><p>Produktivitas dan pemanfaatan pakan yang berasal dari limbah kebun kelapa sawit di Kalimantan Timur belum optimal.

The Impact

Currently the expansion of oil palm is increasing, which at the same time creates a lot of negative responses related to environmental impacts, biodiversity loss, including birds and butterflies species diversity. Nowadays our understanding of the impacts of oil palm plantations is still based on the claim that oil palm plantations are established on primary forest land. The study aimed to estimate the impact of land cover changes, loss of biodiversity, and possible cohabitation between birds and butterflies based on baseline land type before oil palm plantation. The research was conducted at PT Tempirai Palm Resources, to be precise, in the baseline area (shrubs) and plantation areas planted with oil palm using direct and indirect observation methods. Based on research, it was known that land conversion to oil palm plantations caused changes in the number of species, and the diversity of birds and butterflies. The number of bird species in the baseline area was higher (S = 22 species, H ‘= 2.51) than in the plantation area. The number of butterfly species in the baseline area was less (0 species) than in the oil palm plantation area (5 species, H ‘= 1.56, Dmg = 2.23). In general, the increase in bird species’ biodiversity was higher (59.09%) compared to the loss. In contrast, the butterfly species was not lost. A cohabitation also occurred between birds and butterflies at the site. The study concluded that oil palm plantation not only have a negative impact but also a positive impact for biodiversity especially for bird and butterfly.­­­­

Abstract. Nutrient leaching in intensively managed oil palm plantations can diminish soil fertility and water quality. There is a need to reduce this environmental footprint without sacrificing yield. We quantified nutrient leaching in a large-scale oil palm plantation on Acrisol soil with factorial treatment combinations of two fertilization rates (260 N, 50 P, 220 K kg ha−1 yr−1 as conventional practice, and 136 N, 17 P, 187 K kg ha−1 yr−1, equal to harvest export, as reduced management) and two weeding methods (conventional herbicide, and mechanical weeding as reduced management). Each of the four treatment combinations was represented by a 2500 m2 plot, replicated in four blocks. In each plot, soil-pore water was collected monthly at 1.5 m depth for one year in three management zones: palm circle, inter-row, and frond-stacked area. In the palm circle, nutrient leaching was low due to low solute concentrations and small drainage fluxes, resulting from large plant uptake. Conversely, in the inter-row, nitrate and aluminum leaching losses were high due to their high concentrations, large drainage fluxes, low plant uptake, and acidic pH. In the frond-stacked area, base cation leaching was high, presumably from frond litter decomposition, but N leaching was low. Mechanical weeding, even with conventional high fertilization rates, reduced leaching losses of all nutrients. Mechanical weeding with reduced fertilization had the lowest N and base cation leaching whereas its yield and economic gross margin remain comparable with the conventional management practices. Herbicide weed control decreased ground vegetation, and thereby reduced efficiency of soil nutrient retention. Our findings signified that mechanical weeding and reduced fertilization should be included in the Indonesian Ministry of Agriculture program for precision farming (e.g. variable rates with plantation age), particularly for large-scale plantations, and in the science-based policy recommendations, such as those endorsed by the Roundtable for Sustainable Palm Oil association.
