Iswahyudi et al, 2019. Oil Palm Plantation’s Phosporous Mineral Mapping on Babat District South Sumatera. JLSO 8(1):77-85. Soil nutrient status mapping was not initiated which lead to inefficiency in fertilization. Fertilizition without nutrient analysis could lead to nutrient deficiency or toxicity of nutrint. The Purpose of this research was to identify, map the nutrient status and fertilization recomendation of phosporous nutrient status in public oil palm plantation at Babat Village Babat Toman Districts Musi Banyuasin District South Sumatera Province. This research used a detailed survey methode with grid system for 16 sample which represent 16 ha and 60 cm depth of soil drilling. Phosporous nutrient status at research location ranged from 4,81 ppm to 21,86 ppm. 7 ha contained 8-20 ppm available phosphorous ot classified into medium, 6 ha contained < 8 ppm available phosphorous or classified into low and 3 h contained >20 ppm available phosporous or classified into high. Soil reaction (pH) of the research field was 5,0 and 5,5 which classify the soil into acid soil. Fertilization implemented to increase the nutrient status until medium (15 ppm) which resulted in SP-36 doses was 346,22 kg/ha for low nutrient status and 139,33 kg/ha for medium nutrient status.

A pot experiment was conducted at the experimental net house of the Department of Soil Science, Sylhet Agricultural University, Sylhet, Bangladesh to observe the effect of fertilizers on yield and nutrient uptake of local aromatic rice varieties during the Aman season of 2015. The experiment was laid out in a Randomized Complete Block Design with three replications. Five local aromatic rice varieties (Kalizira: V1, Muktasail: V2, Nagrasail: V3, Maloti: V4 and Chinigura: V5) and four packages of fertilizers (F1:  Recommended package i.e. 45-10-20-10-0.5 kg ha-1 of N-P-K-S-Zn, F2: 2/3rd of recommended package, F3: 1/3rd of recommended package, and F4: Control) were used. Urea, TSP, MoP, gypsum and ZnSO4 were used as N, P, K, S and Zn source, respectively. According to the treatment, all fertilizers were applied as basal during final pot preparation while urea was applied in two equal splits (one half as basal and another half at 40 DAT). Nutrient content and uptake of the aromatic rice varieties were significantly affected by the application of different fertilizer packages (with few exceptions). Mostly Kalizira (1.10-0.44-2.31-0.67-13.75 g pot-1 of N-P-K-S-Zn) and/or Nagrasail (1.15-0.46-2.70-0.62-11.74 g pot-1 of N-P-K-S-Zn) varieties showed the highest nutrient uptake in grain and straw with recommended package of fertilizers. While in maximum cases Chinigura (0.41-0.16-0.76-0.197-3.17 g pot-1 of N-P-K-S-Zn) was observed to have the lowest with control treatment. In case of post harvest soil nutrient analyses, Kalizira and/or Chinigura variety associated with recommended package of fertilizers showed the highest nutrient status.

Greenhouse Study

The full dependency on chemical fertilizers in oil palm plantation poses an enormous threat to the ecosystem through the degradation of soil and water quality through leaching to the groundwater and contaminating the river. A greenhouse study was conducted to test the effect of combinations of biofertilizers with chemical fertilizer focusing on the soil fertility, nutrient uptake, and the growth performance of oil palms seedlings. Soils used were histosol, spodosol, oxisol, and ultisol. The three treatments were T1: 100% chemical fertilizer (NPK 12:12:17), T2: 70% chemical fertilizer + 30% biofertilizer A (CF + BFA), and T3: 70% + 30% biofertilizer B (CF + BFB). T2 and T3, respectively increased the growth of oil palm seedlings and soil nutrient status but seedlings in oxisol and ultisol under T3 had the highest in almost all parameters due to the abundance of more efficient PGPR. The height of seedlings in ultisol under T3 was 22% and 17% more than T2 and T1 respectively, with enhanced girth size, chlorophyll content, with improved nutrient uptake by the seedlings. Histosol across all treatments has a high macronutrient content suggesting that the rate of chemical fertilizer application should be revised when planting using the particular soil. With the reduction of chemical fertilizer by 25%, the combined treatment with biofertilizers could enhance the growth of the oil palm seedlings and soil nutrient properties regardless of the soil orders.

<p><strong>Abstrak</strong>. Potensi lahan kering masam tersedia cukup luas untuk dikembangkan menjadi lahan pertanian, kendala utama tingkat kemasaman yang tinggi, hara makro primer dan sekunder rendah, C-organik rendah, kapasitas tukar kation dan kejenuhan basa rendah. Kandungan Al dan Fe tinggi, sehingga menghambat ketersediaan hara, dan dapat berkumpul di daerah perakaran serta meracuni tanaman. Tanah masam lahan kering terletak pada kondisi yang berombak sampai bergelombang, sehingga penataan lahan berdasarkan konservasi tanah perlu dilakukan. Perbaikan tanah merupakan tindakan untuk mengurangi pengaruh kemasaman tanah, ketersediaan Al, dan Fe dengan memberikan bahan ameliorant seperti kapur pertanian, dolomit, bahan organik dan biochar. Penataan lahan dapat dilakukan dengan penanaman disesuaikan dengan kemiringan lahan, pembuatan teras, pengaturan saluran pembuangan air, dan perbaikan tanah di daerah perakaran juga perlu dilakukan. Pemupukan berimbang sangat efektif dan efisien dilakukan pada lahan kering masam yang sudah baik, dan kendala kemasaman diminimalis. Pemupukan berimbang dilakukan berdasarkan pada status hara tanah dan kebutuhan hara oleh tanaman. </p><p><strong>Abstract</strong>. The potential for acid upland is enough available to be developed into agricultural land, the main constraints are high acidity, low primary and secondary macro nutrients, low C-organic, cation exchange capacity and low base saturation. Al and Fe content are high, thus inhibiting nutrient availability, and can gather in rooting and poisoning plants. Upland acid soil is in a choppy to undulating condition, so land management based on soil conservation needs to be done. Soil improvement is an action to reduce the effect of soil acidity, availability of Al, and Fe by providing ameliorant materials such as agricultural lime, dolomite, organic matter and biochar. Land use planning can be done by planting in accordance with the slope of the land, making terraces, regulating the drainage system, and repairing the soil in the root zone. Balanced fertilization is very effective and efficient done on acidic upland that is already good, and minimizing acidity constraints. Balanced fertilization is based on soil nutrient status and nutrient requirements of the plant.</p>

Soil Fertility Improvement

Research to improve soil fertility, especially the chemical characteristics of Ultisol, has been carried out by adding compost and lime. The incubation method of soil plus compost at a dose of 0.5 kg/pot – 2 kg/pot and 1x exchanged Al lime was carried out for 2 weeks. The results of soil nutrient analysis after incubation were an increase in pH of 0.58 points, a decrease in exchanged Al to unmeasured, an increase in the C-organic content of the soil by 3.44%, an increase in the total N-value of the soil by 0.19%, an increase in the amount of soil organic matter. P-available was 5.81 ppm and exchanged K soil increased by 0.02 me/100 g soil. Likewise, the micro elements analyzed also increase. Thus there is a change in the chemical properties of the soil towards the better. The increase in nutrients N, P, K, Ca, and Mg clearly comes from tithonia, which is the result of decomposition of tithonia compost which is added containing high nutrients. In addition, tithonia compost produces organic acids that can dissolve previously insoluble nutrients into soluble ones. The improvement of the chemical properties of the soil towards a better direction is expected to be able to increase the growth of oil palm seedlings planted on the seedling medium growing.

The Relationship

The aim of this study is to analyse the relationship between vegetation indices of Normalized Difference Vegetation Index (NDVI) and soil nutrient of oil palm plantation at Felcra Nasaruddin Bota in Perak for future sustainable environment. The satellite image was used and processed in the research. By Using NDVI, the vegetation index was obtained which varies from -1 to +1. Then, the soil sample and soil moisture analysis were carried in order to identify the nutrient values of Nitrogen (N), Phosphorus (P) and Potassium (K). A total of seven soil samples were acquired within the oil palm plantation area. A regression model was then made between physical condition of the oil palms and soil nutrients for determining the strength of the relationship. It is hoped that the risk map of oil palm healthiness can be produced for various applications which are related to agricultural plantation.
