Abstract

Earthworm is one of the soil macrofauna, which consumes organic matter for body growth and life. Therefore the earthworm can be soil organic status and soil fertility indicator. On the other hand, at present, the organic farming system is developing and positively accepted by people as yield consumer, and yield price is higher than conventional yield price. The experimen to study the earthworm population rate and spread methode was conducted in 2008 planting season, in West Java, with RBD (Randomized Block Design). Three farming system as treatment i.e Organic farming, Semi organic and Conventional farming system and six location as replication. The result showed that Semi organic farming system is the most earthworm population rate and the earthworm distribution is random model.

Abstract

Evaluation of land suitability for soybean by involving the presence and biodiversity of soil fauna has been conducted. The research was done on thecenter of soybean plantations in Ultisols soils in Banten, Lampung, and Lahat (south Sumatera) Provinces. The objective of research was to determine the interaction between soil fauna diversity in Ultisols soil and productivity of soybean. The research used a Survey Method. Every location was divided into three categories of vegetation performance, such as, less vegetation, average vegetation, and very fertile vegetation with two replicates. The chemical, physical, and biological properties of soils from every unit sampling were analyzed. The results showed that nutrient and chemical properties of soil which directly influenced the growth and production of soybean was P-potential, P-available, K-available, B (Boron), Ca and pH; the physical properties were pores drainage, pores rapid drainage, soil water content, and soil permeability. The presence of earthworm did not have direct effect to soybean, except as the 3th between variables, meaning that the presence of earthworms affected soil physical properties, soil physical properties affected nutrient availability, nutrient availability affected the biomass and yield of soybean.Keywords: Earthworm, land suitability, soil fauna, soybeans, Ultisol [How to Cite: Anwar EK, R Nurlaily, Sarmah and J Purwani. 2013.

Abstract

Effectivity of the Earthworms Pheretima  hupiensis, Eudrellus sp. and Lumbricus sp. on the Organic Matter  Decomposition Process (E.K. Anwar): The earthworms  are the one of soil fauna  component in  soil ecosystem have an important role in organic matter decomposition procces. The earthworm feed  plant leaf  and plant matter up to apart and dissolved.  Earthworm  metabolisms  produce like faeces that mixed with decomposed organic matter  mean vermicompost. The vermicompost fertility varies because of some kind of earthworm differ in “niche”  and attitude. The experiment was to study the effectivity of earthworm  on organic matter decomposition which has been conducted in Soil Biological and Healthy Laboratory and Green House of Soil Research Institute Bogor, during 2006 Budget Year. The three kind of earthworms i.e  Pheretima hupiensis, Lumbricus sp. and Eudrellus sp. combined with three kind of organic matter sources i.e rice straw, trash and  palm oil plant waste (compost heap). The result shows that the Lumbricus sp.  are the most effective decomposer compared to Pheretima hupiensis and Eudrellus sp. and the organic matter decomposed by  Lumbricus sp. as followed:  market waste was decomposed of 100%, palm oil empty fruit bunch (compost heap) 95.8 % and rice straw 84.9%,  respectively. Earthworm effectively decreased Fe, Al, Mn, Cu dan Zn.

Abstract

The effectiveness of Commercial Biofertilizer 1 (CBF1) on the growth and yield of caisim (Brassica sp.) was examined in the greenhouse of Indonesian Soil Research Institute in Bogor. The completely randomized design (CRD) was performed to examine the effects of Commercial Biofertilizer 1 (CBF1) on Fertilization Efficiency in Ultisols. The treatments were consists of 10 combinations between NPK-recommendation (NPK-rec) and CBF1, with six replications. The experiment was conducted from August to October 2009. The result showed that CBF I increased the yields of caisim when combining by fertilizer NPK-rec, while giving CBF1 alone did not significantly increases yields compare to control (without fertilizer). Giving ¾ dosage NPK-rec. + CBF1 had RAE value 163%, indicating the effectiveness of  CBF1 was optimum, that it reduce the need of NPK fertilizer by 25% by providing the increasing of yield  63% compared to NPK rec. The higher the level of NPK-rec. the lower the efficiency of fertilization. CBF1 had given effectives on yields when it was combined by inorganic fertilizer. However, when it was not combined with inorganic fertilizers, it would harm plants and decreased the soil nutrients.  The influence of biofertilizer in plants were predictable unpredictable, while the influent of inorganic fertilizers were predictable.
