Abstract

This study investigated the effect of different leaching rates on the downward movement of zinc applied, as fertilizer, on the surface of a sandy soil. The experiment was conducted in polyethylene bags filled to 30 cm depth with sandy soil. A zinc supply of 15.3 10-3 cmolc kg-1 was applied to the soil surface as a solution of zinc sulfate. Three leaching rates were tested: 31 mm, 208 mm and 497 mm. Results showed the absence of zinc in the leachate for all leaching rates. Within the soil profile, the highest content on exchangeable zinc (15.3 10-3 cmolc kg-1) was recorded in the top soil layer (0-10cm) for all leaching rates. In the middle (10-20 cm) and in the lower (20-30 cm) layers, the exchangeable zinc content remained similar to that recorded before leaching (0.76 10-3 cmolc kg-1). The percentage of the cation exchange capacity occupied by zinc in the top soil layer increased after leaching. It averaged 0.35% for all leaching rates while it remained similar to that recorded before leaching (0.03%) for the middle and the lower layers. This increase was linked to the adsorption saturations sites particularly released by manganese, potassium, calcium and ammonium after their downward movement.

Abstract

Antherura rubra Lour. is one of the critical plant at Cibodas Botanical Garden. Study  of cultivation through vegetative propagation of A. Rubra is rare. Therefore, the research of A. rubra on various of media and inorganic fertilizers is required  to conserve  A.rubra at Cibodas Botanical Garden. This study was conducted at the Nursery - Cibodas Botanic Garden for 10 months. The experiment was conducted in randomized block design (RBD) with four replications. Treatments consisted of three combinations of natural compost media with three levels of inorganic fertilizer (0, 1, and 2 dose of level), three katalek compost combination with three levels of inorganic fertilizer and a control (top soil without inorganic fertilizers). Variable tested consists of plant height, number of leaves, and dry weight shoot and root as an indicator of growth A. rubra Lour. The results showed that the growth of seedlings A. rubra Lour. on katalek compost  media's with one dose of levels inorganic fertilizer growth better than other treatments.

Abstract

Sustainability of paddy field becomes the main concern as the media of biomass production, thus it is needed a data and information about land characteristics to find out its degradation. Mapping of soil degradation potency in paddy field is an identification of initial soil condition to discover the land degradation potency. Mapping was done by overlaying map of soil, slope, rainfall and land use with standard procedures to obtain its value and status of soil degradation potency. Area mapping is an effective land for biomass production (natural forest, mixed farm, savanna, paddy field, shrub and dry field) with approximately 43,291.00 hectares (ha) in Sidoharjo, Girimarto, Jatipurno, Jatisrono, Jatiroto, Tirtomoyo, Nguntoronadi and Ngadirojo District. The result shows that soil degradation potency (SDP) in Districts of Sidoharjo, Girimarto, Jatipurno, Jatisrono, Jatiroto, Tirtomoyo, Nguntoronadi and Ngadirojo are very low (DP I) 0.00 ha (0.00%), low (DP II) 20,702.47 ha (47.82%), moderate (DP III) 15,823.80 ha (36,55%), high (DP IV) 6,764.73 ha (15.63%) and very high (DP V) 0.00 ha (0.00%). Paddy field is 22,036.26 ha or about 50.90% of all area as effective biomass production, its SDP considers as low (DP II) 16,021.04 ha (37.01%) and moderate (DP III) 6,015.22 ha (13,89%). Paddy field has a low SDP because it is commonly lies on flat area and conservation method by the farmer is maintaining the paddy bund and terrace. This study needs an advanced study to identify actual SDP through detail verification in the field, and also support by soil sample analysis in the laboratory.

Abstract

Peatlands which is limited in chemical, physical and ecology require appropriate management for oil palm plantation. Coastal sediment as an ameliorant in peatlands increased productivity some crops. This study aims determining the effect of the doses of coastal sediment as ameliorant on peatlands to the availability of N, P, K, Ca, Mg and Na oil palm plantations. This research was performed in the area of oil palm plantation in Kubu Raya district, Borneo, Indonesia. Experimental design employed randomized block design with 4 levels of coastal sediment doses (L), i.e. L0 = 0 t ha-1; L1 = 20 t ha-1; L2 = 40 t ha-1; L3 = 60 t ha-1 with three replication. The results showed that the application of coastal sediment at 40 t ha-1 in oil palm plantations significantly increased soil pH, availability of N, K, Ca and Mg, while P was not significantly different

Abstract

Application of fertilizer recommendations until now is generally treated equally in all locations. The variety of soil fertility in location was not relevant to use one dosage fertilizer recommendation. The purpose of this study was determine rice of recommendation dosage of NPK phonska fertilizer in rice fields. This study compared the fertilization treatments of NPK phonska based on the method of field experiments in rice fields by using a randomized block design, where each treatment was repeated four times. The treatment were P0 : without NPK Phonska and Urea fertilizer (control), P1 : NPK Phonska 300 kg ha-1 and Urea  200 kg ha-1, P2 : NPK Phonska 200 kg ha-1 and Urea  235 kg ha-1, P3 : NPK Phonska 250 kg ha-1 and Urea  220 kg ha-1, P4 : NPK Phonska 350 kg ha-1 and Urea  180 kg ha-1. The results showed plant highest in the treatment of P2 at 106 cm, where the fertilization treatment of  NPK Phonska at 200 kg ha-1 and Urea at 235 kg ha-1. The fertilization with NPK Ponska 350 kg ha-1 and Urea 180 kg ha-1 (P4) showed the most number of tillers at 12.2 tillers and the highest of grain weight per hill at 29 grams.  It can produce dry grain (stand for 14%) at 7.5 t ha-1 and the profits is IDR 22,773,581,00.
