Manure contains micro and macro nutrients which are essential for plant growth. During the decomposition process and after application to the soil, nutrients in manure especially nitrogen is easily volatile to the atmosphere and leaching by water. Zeolite has a high adsorption to ammonium ion, so the application of zeolite together with manure may improve the plant growth. The objective of this research is to evaluate the effect of manure and zeolite addition to the growth and absorption of plant nutrients of Ipomoea reptans. This research was conducted in green house of Department of Soil Science, Faculty of Agriculture, Bogor Agricultural University, from June until October 2004. Cultivation was conducted in two period. Immediately after the plant were harvested in first period, plant media were cultivated for the second period without addition of fertilizers. Addition of 20 ton/ha zeolite to the plant media influence the growth and absorption of nutrient higher than the other zeolite treatments. Nutrient residue of zeolite treatment is higher than the treatment without zeolite which is shown by higher production of Ipomoea reptans in the second planting period. Application of zeolite increase the growth of plant. Application of zeolite together with chicken manure gave higher growth and production compared with cattle manure.

Economic characteristic of The Boven Digoel Regency is dominated by agriculture. Food crops has an important role in agricultural and economic development in Boven Digoel Regency. The objectives of this paper are : (1) Identifying and establishing food crops as the superior commodities, (2) Delineating the land availability for superior food crops development, (3) Assessing land suitabilityof superior food crops commodities and (4) Arranging direction development of superior food crops commodities in Boven Digoel Regency. The methodology used in this paper were consisted of the analysis of Location Quotient (LQ), Shift Share Analysis (SSA), and evaluation of the land availability and land suitability. Results of LQ and SSA analyzes showed that cassava, sweet potato, paddy, corn and peanuts are the superior food crops commodities. The results of analyzes of land availability are presented in three scenarios. In the first scenario, available land covers an area of 36.227 ha, in the second scenario available land covers an area of 43.401 ha, while in the third scenario, available land covers an area of 610.990 ha. Evaluation of the suitable land in available land indicated that most of the land include in S3 class (marginally suitable), whilew the least area include in N class (not suitable). The developments of food crops in Boven Digoel were then done by considering the suitable and available land as well as comparative and competitive advantage of the comodities.

Paddy soil has different morphology and pedogenic characteristics compared to dry land, due to the influence of inundation during several months in a year. Puddling and drying that occurs in turns (redox cycle) in paddy soil can lead to the formation of concretions or rusty Fe and Mn. The main purpose of this study was to understand the changing of the morphological and chemical properties as a result of changing of the dry land to paddy soil. Besides, the study also aimed to understand plow pan layer formation in Podsolic, Latosol, Regosol, and Andosol soil type. Results showed that content of soil density (bulk density) of dry land ranged from 0.5 to 1.0, while paddy soil is 0.8 to 1.0 (g cm-3). Bulk density values in all four types of soils increased after the changing. Observation also demonstrated that severity levels of paddy soil is higher than dry land, especially in the second and third soil layers or under the surface of soils. Acidity of dry land was likely to be higher than paddy soil. There were no significant differences in nutrient such as C-organic, P and N. Meanwhile, using dithionite as solvent, paddy soil has higher Fe, Mn, and Al content than that of dry land, and remain the same when extracted with pyrophosphate and oxalate. From the four types of soil observed,the paddy soil showed formation of plow pan layer. This was shown by the soil severity level higher than the topsoil or other layers. Paddy soil had unique properties due to redox reaction, thereby providing soil discoloration i.e darker due to high solubility of Fe, Mn, and Al.Keywords: Concretion of Fe and Mn, paddy soil, pedogenesis, plow pan layer [How to Cite: Kurniati, Sudarsono and Suwardi. 2016.

Productions of crude palm oil (CPO) produce waste which include the empty oil palm fruit bunch (EOPFB), palm oil mill effluent, shells, and fiber. The combustions of shell and fiber as boiler feed produce waste in the form of boiler ash. Boiler ash is very potential to use as an additive to improve quality of the EOPFB compost. The objectives of this research were to study : 1) effect of boiler ash on the quality of the EOPFB compost, 2) effect of EOPFB compost on the chemical properties of Ultisol, and the yield of mustard. The first experiment was about quality improvement of compost from EOPFB by the addition of boiler ash. The treatments applied were four dose levels of boiler ash: K1= 0%, K2 = 15%, K3 = 25%, and K4 = 35%. The second experiment was greenhouse pot experiment. This experiment was consisted of thirteen treatments with three replications arranged in completely randomized design (CRD). The treatments applied were: four types of compost from the first experimental results aplied to the soil with four dose levels, i.e : 0, 10, 20 and 30 Mg ha-1. The results showed that the addition of boiler ash at the beginning of the composting process improved the quality of the EOPFB compost: which increased pH, amount of humic acids, macro and micro nutrients content and decreased content of Pb. The aplication of all compost –K1, K2, K3, K4– to Ultisol increased pH H2O, P2O5, organic-C, total-N, exchangeable-Ca, exchangeable-K and yield of mustard and decreased exchangeable-H, exchangeable-Al. Moreover the yield of mustard was increased about 84% (33.9 g plant-1) with K4 at doses 20 Mg ha-1 and 85% (34.1 g plant-1) with K3 at doses 10 Mg ha-1.

It is generally known that zeolite has potential for heavy metal adsorption. The objectives of this study were to synthesize and characterize zeolite ZSM-5 and to figure out the adsorption capacity of zeolite ZSM-5 for heavy metals of Cu2+, Pb2+ and Cd2+. Characterization of zeolite ZSM-5 included some variables i.e. crystal structure (XRD), morphology (SEM), specific surface area and total pore volume (N2 physisorption). Adsorption capacity of zeolite ZSM-5 was analysed using a batch system with heavy metals of Cu2+, Pb2+ and Cd2+ in various concentrations (50, 100, 150, 200 and 250 ppm) with contact times 30, 60, 90, 120 and 250 minutes. Adsorption data was calculated by Langmuir and Freundlich isotherm. The results showed that the maximum adsorption capacity of zeolite ZSM-5 against heavy metals of Pb2+, Cu2+, and Cd2+, were 74.07, 69.93 and 60.24 mg g-1, respectively. These indicated that synthetic zeolite ZSM-5 had potential to adsorb heavy metals. The results also suggested that the adsorption capacity was affected by the pore size of zeolite, negative charge of zeolite, diameter of hydrated and electronegative ion.

The transport of nutrien causing eutrophication in water from catchment area especially fosforus (P) through runoff is determined by type of landuses, slop, soils type, and land cover (Jeje,2006) . The research was conducted using a survey method. The sampling technique was done by a purposive sampling on any flooding in the rivers that pass through areas with specific land use (settlement, forest, plantations, agricultural fields and rice field). The main parameters were river discharge and the content of nutrients causing eutrophication that was phosphorus (P) in rivers. The P loadingfrom cacthment area to Mrica reservoir was 11,526,706.14 kg/year and the load allocation (LA) was 3,833,587.70 kg/year. The reservoir operational of power generating dan flushing activity were able to manage the LA up to 1,147,329.09kg/year, so the TMDL of Mrica reservoir become 4,980,916.78kg/year. It was concluded that the highest transport of P was from paddy field and then followed by respectivelly agricultural (potato) field, plantation (perhutani) field, settlement area, and forest area.
