Two studies of zeolite application on oil palm seedlings for repair media of planting using a sandy soil type to seedlings media of oil palm have been conducted by The Oil Palm Research Center at experimental garden Aek Pancur, North Sumatra. Research I using Typic Udipsamment soil with 4 dose level of zeolite (0,50,100, and 150 g / polybag). Research II using tin tailings which treated zeolite soil amelioran materials, empty fruit bunch compost, dolomite, and also compared with the top soil is Typic Hapludult. The study I showed that application of zeolite is generally able to increase nutrient content in soil and soil cation exchange capacity inclined growth of better seeds. However, at doses of 150 g/polybag, zeolite application actually lowers the pH and increasing Aldd was followed by poor seedling growth. The study II using tin tailings as planting media, zeolite application has not yielded as good as empty fruit bunch compost applications to support seedling growth and nutrient uptake. Continued research related to determining the appropriate dose, and combination with other soil amelioran materials to increasing effectiveness of zeolite in improving the physical, chemical, and biological soil charachteristic as a medium sand fraction dominated planting of oil palm breeding is still very necessary.

Zeolite has been known for improvement of soil fertility through increasing the cation exchange capacity. The objective of this research is to evaluate the application of zeolite for improvement of growth media and growth of oil palm seedling. The research has been conducted in the oil palm seedling research area of Aek Pancur using completely randomized design. The soils used for media are Typic Paleudults, Typic Udipsamments, and Typic Hapludults. The treatment composed of 4 zeolite dossages 0,50, 100, and 150 g/polybag. The results showed that application of zeolite to soils improved the properties of soils, especially cation exchange capacity. Application of zeolite as soil amelioration in the seedling of oil palm did not significantly improve the growth and absorption of nutrients during 11 months. In general, application of zeolite with the dosage of 100 g/polybag improve the growth and absorbtion of nutrients compared to without zeolite application. On the othe hand, application of 150 g zeolite/polybag decrease the growth and absorbtion of nutrients.

Manajemen kesuburan tanah yang rutin dilakukan di perkebunan kelapa sawit cenderung tidak memperhatikan kesuburan dari aspek biologi tanah. Penggunaan pupuk anorganik menjadi praktik standar yang umum, akan tetapi dapat mempengaruhi kesuburan dan kesehatan tanah. Produk hayati yang mengandung konsorsium bakteri bermanfaat dapat menjadi alternatif untuk meminimalkan bahaya terhadap lingkungan dan mewujudkan pertanian berkelanjutan. Penelitian pengaruh aplikasi pupuk hayati terhadap pertumbuhan dan produktivitas kelapa sawit telah dilakukan dengan sistem demo plot (demplot) pada tanaman menghasilkan TT 2008 yang berlokasi di Sumatera Selatan sejak tahun 2019. Penelitian disusun menggunakan rancangan acak kelompok (RAK) dengan lima perlakuan. Hasil penelitian menunjukkan bahwa populasi bakteri secara nyata mengalami peningkatan dan menunjukkan nilai yang lebih tinggi (menjadi >108 cfu/g-1) pada plot aplikasi pupuk hayati. Sementara itu, performa vegetatif tanaman meningkat sekitar 8,5-17,2% (luas daun) dan 8,6-14,9% (berat kering pelepah) terhadap kontrol (100% anorganik). Perlakuan pupuk anorganik (50% dan 75%) yang dikombinasikan dengan pupuk hayati dapat meningkatkan efisiensi pemupukan dan menghasilkan produktivitas tanaman kelapa sawit yang tidak berbeda nyata terhadap perlakuan standar (100% pupuk anorganik).

This study was conducted to determine the root distribution and to analyze soil physical factors that affect roots development in different size of planting hole; standard (0.6 m x 0.6 m x 0.6 m), medium ((1 x 1 cm x 0.6 m) with 400 kg empty fruit bunches (EFB)/hole and 740 g urea/hole, and big (2.8 mx 2.8 mx 1 m) with 400 kg EFB/hole and 740 gr urea/hole. This study employed demonstration plot that used a non factorialrandomized block design (RBD) with three treatments (standard, medium, and big hole) and three replications. The results showed that total distribution of oil palm roots in standard, medium, and big planting 3 3 hole are respectively 28.60 g /dm ; 26.69 g/dm ; and 3 24.47 g/dm . Types of planting hole did not significantly affect primary root, but significantly affected secondary and tertiary root distribution. In big planting hole, oil palm has highest secondary and tertiary roots distribution than the others (up to 70%). Increasing ofpermeability, porosity, and decreasing of soil bulk density tends to increase root distribution, especially tertiary. Meanwhile, increase on soil water content is not followed by secondary and tertiary distribution, since booth root types more distributed in the upper soil layer. Better soil tillage; through big planting hole, can improve soil properties and optimizing development of secondary and tertiary roots.

Prolonged dry season, land fire, and haze disturbance occurred during El Niño 2015 in Indonesia. A study had been conducted to identify impacts of prolonged dry season and haze disturbance on ecophysiology of oil palm in Dawas Estate, South Sumatra. The study was conducted by collecting data of precipitation, visibility, oil palm fronds addition, rate of photosynthesis, Photosinthetically Active Radiation (PAR), and Elaeidobius kamerunicus activity on mature and immature palm before, during and after the incidence of drought and haze disturbance. T test was used for statistics analysis. The results showed that water deficit was recorded in July, August, September and October, it was 45, 92, 80, and 148 mm respectively. Dry month (precipitation was ≤ 60 mm) was 2 months, while dry spell occurred 3 times in June to July (33 days), August to September (42 days), and September to October (40 days). Haze disturbance occurred in August to November, it had decreased visibility to 80%. During drought stress and haze disturbance, there was decrease in fronds addition, photosynthesis rate and bunch productivity in following year. In addition, haze disturbance had decreased number of Elaeidobius kamerunicus visitting female flowers up to 95%.

A field study on peat soil to investigate impacts of soil water table depth and soil ameliorant (steel sludge) had been carried out on mature oil palm. Three treatments of soil water table management and four rates of steel sludge application were applied in this study. Treatments of soil water table management were WLM1, WLM-2, and WLM-3, where soil water table depth was maintained at 35-50 cm, 60-75 cm, and >75 cm below the soil surface, respectively. Treatments of steel sludge were application of this soil ameliorant at the rate of 0; 3.15; 6.51; 9.86 kg tree-1. The study was arranged as split plot randomized block design by assigning soil water table management as main plot and rate of steel sludge as sub plot. Soil Data observed were actual soil water content, peat soil properties, CO2 emission, vegetative growth, and palm yield. The results showed that maintaining soil water table depth at < 75 cm could maintain actual soil moisture up to top parts of peat soil. On the other hand, deeper soil water table (>75 cm, WLM-3) caused significant effects on decreasing of soil moisture in the 0-10 cm layer of peat soil. CO2 emission was 37, 40, dan 45 ton ha-1 year-1 under WLM-1, WLM-2, and WLM-3, respectively. The drop of soil water table to >75 cm (WLM-3) significantly increased CO2 emission to about 11-18% higher than that on WLM-1 and WLM-2. Steel sludge application did not significantly decrease CO2 emission. The highest FFB yield was observed under WLM-1, then followed by WLM-2 and WLM-3. FFB yield was significantly higher when soil water depth was maintained at 35-75 cm than that at > 75 cm, it was 7-10% and 36-60% higher in 2014 and 2015, respectively. There were no significant effects of steel sludge application on FFB yield, but there was improvement on average bunch weight.
