The aimed of this research was to find out the level of agricultural land productivity with Storie Index Method and predict oil palm productivities based on land productivity. This research had been done since May until August 2014 at Bangka and West Bangka District. The landuse consisted with forest, crop fields, plantation, paddy soils and heath. The slopes consisted with vary on declivity; 0-8 %, 8-15 %, 25-40 % dan > 40 %, meanwhile the soil’s great group consisted with Haplohemists, Hapludox, Endoaquepts, Hydraquent, Udipsamments dan Dystrudepts. The district was on two type of rain fall, there was 2750 and 3000 mm/year. Analisys unit was land units that build from overlay those land variable. There was 24 land unit as research analisys unit. Data analisys used Storie Index Rating as parametrics approach. The result of this research showed that the level of productivity in Bangka and West Bangka District was excellent, good, moderate, and poor. The most extensive land quality is at grade 3 or medium quality is amounted to 394.668, 97 Ha or 70,49 % of total areas. Based on land productivity levels, productivity of oil palms counted that higher potential was in medium class with productivities range 11-18 tonnes/Ha/years. This area was speard 536.242,34 Ha or 95,78 % of total areas.Key words: Land productivity, storie index, oil palm productivities

Soil quality test is needed to find out the influence of landuse change due to soil quality dan characteristics. This research aims to comparing various land use that influence the physical, chemical and biological soil on Andisol and Inceptisol, obtain information of soil quality at various land uses on Andisol and Inceptisol, and study the relationship between soil quality and erosion at various land use The study was conducted in Sub Sub watershed Hulu Cimanuk with an area of 16.171 hectares. The study was conducted on four different types of land use namely forest land, agriculture land, tea garden and mixed garden. The study was conducted with survey methods, descriptive and comparative. Erosion calculation using the RUSLE formula.Analysis of soil quality is calculated based on criteria Mausbach & Seybold (1998) and modified in accordance with the conditions of the study area. The results showed that each land use has a different effect on soils quality nor with erosion. Soil quality on forest land has higher value than other land use and erosion that occurs most low at 0.2 tonnes / ha / year. The use of dry land has the lowest value of soil erosion begitupula highest of 387 tonnes / ha / year.Key words: erosion, landuse change, soil quality, and watershed.

Soil is a very complex and dynamic system, consisting of the solid, liquid and gas. The solid parts of soil is made from minerals and organic materials (rough and smooth). Organic materials with smooth from is called humic acid. This product is a result from oxidation polimeritation of compounds like phenol, lignin and proteins from plants also from the metabolism of microorganism in the ground. In general, the composition of organic matter is dominated by humin with large, medium and lower of molecular weight. Humic acid has the composition of elements like carbon (4080%), nitrogen (2-4%), sulfur (1-2%), phospor (0-0,3%) and also oxygen. Humic acid has unique characteristics compared with fulvic acid and humin. One of the most spesific character is the bonding to interact with metal ions, oxide, hydroxide, minerals, organic, and toxic materials. Key words: Adsorbtion, Characterization, Heavy metals, Humic Acid

Mineral content of the soil determines various properties including nutrient that can bereleased during the weathering process. The research to identify the minerals in Andisol developedfrom the eruption of Mt. Tangkuban Parahu and Mt. Patuha had been conducted to determine theminerals content in the sand fraction. This research was conducted in several steps: the field survey,soil sampling, and laboratory analysis. The field locations were in the forest of Cikole, Lembang,West Java derived from the eruption Mt. Tangkuban Parahu and in the forest of Patengan,Rancabali, West Java derived from the eruption of Mt. Patuha. Sand fraction was separated from siltand clay by wet sieving method, using the 50 micron siever. Microscopic observation for identifyingthe minerals was done with polarization microscope to the color, luster, shape of grains and crystals,cleavage, hardness, transparency, translucent, and magnetic properties. The results showed that thesand fraction of Andisol derived from Mt. Tangkuban Parahu and Mt. Patuha had the mineralcontent as hypersthene, diopside, orthoclase, oligoclase, anorthite, andesine, hornblende, biotite,quartz, corundum, magnetite dan sulphur, showed that the weathering those minerals cancontribute some nutrients like Mg, Ca, K Fe, and S to the soilKey words: hyperstene, diopside, anorthite, hornblende, biotite

Biofertilizer and N, P, K fertilizer combination is expected to decreased the application dosage of inorganic N, P, K fertilizer and increased the yield of maize. This experiment was conducted to describe the effect of N, P, K fertilizer and biofertilizer combination to the population total of soil microbes and yield of maize (Zea mays L. saccharata) on Inceptisols Jatinangor. This experiment was carried out Ciparanje Experimental Station, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor with altitude 820 meters from October 2015 to January 2016. This experiment was arranged in randomized block design which consisted of ten combinations and three replications. Ten combinations were: control; NPK standard dosage; biofertilizer standard dosage; ¼ of NPK + 1 of biofertilizer; ½ of NPK + 1 of biofertilizer; ¾ of NPK dosage + 1 of biofertilizer; 1 of NPK + 1 of biofertilizer; ¾ of NPK + ¼ of biofertilizer; ¾ of NPK + ½ of biofertilizer; and ¾ of NPK + ¾ of biofertilizer. The experiment showed that the combination of NPK and biofertilizer gave a significant effect to increased yield of maize. The standard dosage of biofertilizer reduced 50% of the NPK application and increased the yield of maize by 13,85% efficiently.Keywords: biofertilizer, NPK uptake, soil microbe, maize

The productivity of potatoes in Indonesia is relatively low and unstable caused by unsuitable enviromental and soil conditions and bad cultivation system. This research was conducted to study the effect of NPK fertilizer dosages and soil order to soluble K, K Uptake, and yield of seed potatoes (Solanum tuberosum L.). The experiment design used a factorial randomized block design with two factors and three replication. The first factor was NPK fertilizer dosages with five levels (0, 25, 50, 75, 100% recomendation dosages) and the second factor was soil orders with two levels (Andisols and Inceptisols). The results of experiment showed that the interaction effect between NPK fertilizer dosages and soil orders had significantly effect to soluble K and K Uptake. There were independent effect of NPK dosages to diameter of potatoes tuber and independent effect of soils order to yield of seed potatoes. Andisols with 25% NPK and Inceptisols with 50% NPK were the best combination treatment to increase soluble K while treatment Inceptisols with 25% NPK was the best combination treatment to increase K Uptake. Dosages of 25% NPK was the best treatment to increase diameter of potatoes tuber while Inceptisols was the best treatment to increase yield of seed potatoes.Keywords : NPK Fertilizer Dosages, Andisols, Inceptisols, Potassium, Potatoes

Marginal soils have problems of low availability of nutrients, especially phosphorus. Phosphate solubilizing microbes can produce organic acid that dissolve P in the soil. Futhermore, the PSM also produce extracellular enzymes asa phosphatase that catalyze mineralization of organic P become inorganic P. Phosphate solubilizing bacteria (Pseudomonas mallei and Pseudomonas cepacea) and phosphate solubilizing fungi (Penicillium sp. and Aspergillus sp) is selected based on the ability of dissolving P and the production of growth regulators. Research at this stage aims to determine the biological fertilizer application techniques (PSB and PSF) as well as different types of P fertilizers to improve soil P available, growth and yield of maize. Field experiment on Ultisol Jatinangor implemented using a randomized block design (RBD) to test how applications PSM plus (giving 1, 2 and 3 applications) as well as the type of fertilizer P (SP-36 and rock phosphate). The results showed that the application of PSM can improve soil P-available growth and yield of maize. Application of PSM biological fertilizer could reduce the need for fertilizer P by 50%. PSM application once the application (early planting) with SP-36 dose 50% can increase content of soil P (P-available), and yield of maize on Ultisols.Keywords : maize, phosphate solubilizing microbes, Ultisols
