Abstract

This research was conducted to study the population and diversity of soil and leaf litter mesofauna in arable soils under different types of vegetation and slope at the Agriculture Experimental Field (AEF) of University of Lampung. This study was designed to use the survey method. The soil and leaf litter samples were taken from different vegetation and slope classes. Observational variables included population and diversity index of soil mesofauna (H’), soil temperature, soil moisture content, soil pH, soil organic-C, soil total-N, and soil C/N ratio. The data of population distribution were presented in a boxplot diagram and the correlation between soil properties and mesofauna population or mesofauna diversity index were presented. The results showed that the most abundant soil mesofauna was observed in the plots with sugarcane vegetation, either sampled at the end of dry season (November 2015) or at the beginning of rainy season (April 2016). However, the highest number of leaf litter mesofauna was found in the plot with cassava vegetation. This result suggests that the cassava leaf litter most likely became the preferred substrate for mesofauna. In all treatments, the value of mesofauna diversity index (H‘) was categorized as low according to the Shannon-Weaver index. Two dominant orders frequently found in almost all vegetation types were Acarina and Collembola. The results of correlation analysis indicated that only soil pH sampled on November 2015 was positively correlated with the mesofauna population (range of pH 5.0 to 6.6). Soil moisture content sampled on November 2015 and soil C/N ratio sampled on April 2016 were positively correlated with the diversity index of soil mesofauna, respectively. Soil total-N sampled on November 2015 was negatively correlated with the soil mesofauna diversity index. The increase of leaf litter biomass appeared to promote the increase of the leaf litter mesofauna population, but not the diversity index.Keywords: diversity index, leaf litter, soil mesofauna, vegetation

Abstract

Effect of the age and root distance of maize on the population of phosphate solubilizing microorganisms was studied. The rizosphere and non-rhizosphere soil of maize was setup in the special pots with dimension of 60 cm x 60 cm x 30 cm in the glasshouse.  The Ultisols soil was planted with maize until the vegetative stages. The results showed that  on the distance of  > 20 cm from center of roots, the age of maize increase the population of phosphate solubilizing microorganisms.  The population of phosphate solubilizing microorganisms in the rhizosphere soil was 8 - 23× more than from those non-rhizosphere soils. On the distance of 0-10 cm, the age of maize affected the number of phosphate solubilizing microorganisms in the rizosphere and non-rhizosphere soil. Available-P (Bray I) was affected by the age and distance of root maize.  The highest value was observed on the 7 weeks after planting at a distance of >20 cm.  Available P was significantly higher in the rhizosphere soil than that in non-rhizosphere soil, especially at a distance of >20 cm on the 7 weeks after planting.  The positive correlation was occurred between phosphate solubilizing microorganism and the value of available-P, soil pH, organic C and total N.

Abstract

Hilly area Sumberjaya, West Lampung Province, South Sumatra, Indonesia, is one of the Province where deforestation  increasing in the past 30 years as a result of the implementation of agricultural systems, especially coffee plantation. it is important to study the soil fauna in these natural relicts. Six sites (3 naturals and 3 managed systems) were studied in order to identify earthworm species communities, using the hand sorthing  method and soil chemical parameters (pH, avail-P, org-C., tot-N, and cation exchange capacity (CEC). Two species were found (Pheretima sp. and Pontoscolex sp.). All land use systems had very similar soil chemical characteristics, there can be characterised as acidic (pH between 3.6 and 5.0). A high content of organic carbon was in natural sites (bush 4.0 % and primary forest 3.9 %),  and a low content was in managed sites (coffee plantation 2.1 %). Total nitogen (0.37 %) and CEC (21.84 Cmol-c kg-1) was in primary forest.  However, the earthworm densities were significantly lower under primary forest than in the other sites. The acidity component explained mainly   the lowest earthworm population at the primary forest (soil pH 3.6). The use of succession forest (bush) and mix farming showed a positive effect on soil fertilit.

Abstract

The objectives of the research were to compare the quality of physical and chemical characteristics of the soils in the oil palm plantations applied with integrated farming system of cattle and oil palm plantation (IFSCO) and without IFSCO (non-IFSCO), as well as to evaluate the economic benefits of IFSCO application. The research was conducted in two oil palm plantations, i.e. an oil palm plantation applied with IFSCO (5 ha) and an oil palm plantation without IFSCO application (non-IFSCO) (5 ha), located in the Karya Makmur Village, Penawar Aji Subdistrict, Tulang Bawang District, Lampung, Indonesia, in June until August 2016. The research was conducted using a survey and systematic sampling methods to collect soil samples, and data from 30 farmers who applied IFSCO and other 30 farmers who applied non-IFSCO. The results showed that the application of organic fertilizer in the IFSCO field resulted in higher level of exchangeable-K, -Ca, -Mg, and -Na, cation exchange capacity (CEC), and organic-C content of the soil;and better improvement on the physical soil quality, i.e. bulk density, porosity and soil moisture content; in comparison to that in the field without organic fertilizer application (non-IFSCO field). However, the application of IFSCO did not affect the pH, available-P, base saturation and total-N content of the soil.  There was a difference in the texture class of the soils in the IFSCO field and non-IFSCO field.  The result of texture analysis showed that the texture of the soil in the IFSCO field is “clay”, while the texture of the soil in the non-IFSCO field is “sandy clay loam”.  Application of IFSCO can save the fertilizer cost by 66%, the feed cost by 50%, and can increase oil palm production and farmers’ income by about 25%, so it is economically profitable. Thus, IFSCO can improve soil quality and provide economic benefits for the farmers, so the IFSCO obviously supports the implementation of sustainable agriculture.

Abstract

Protozoa and alga play important roles in biogeochemical nutrient cycles in freshwater environment, especially in the paddy fields.  The changes from the conventional technologies to organic technologies will change the communities structures of organisms lived in the paddy fields environment.  The fields experiment was conducted to study the population dynamic of protozoa and algae dominant inhabited in  the floodwater of the paddy fields subjected by continues ‘bokashi’ application.  The results showed that protozoa and algae inhabited in the paddy fields in present study were dominated by Euglena, Pleodorina, Volvox, and Diatom. The continued application of  bokashi for 4 years significantly increased the total population of protozoa and algae, however, the significantly effect was obtained in the population of Volvox only.  The population of protozoa and algae were affected by the time of flooding of paddy fields where it increases exponentially at the 20 and 30 days after flooding and stable after that, ecxept for Euglena where it increases little by little with time of flooding.

Abstract

Agroindustrial wastewaters were considered not maximum used in Lampung Province since it has acidic properties that can be used as an acid solvent. This study aimed was to explore the most potential agroindustrial wastewaters in dissolving phosphate rock by acidulation in the laboratory scale. The experimen were arranged by factorial i.e. first factor were phosphate rock origin (Sukabumi, west Java and Selagailingga, central Lampung) and second factor was kinds of solvent (agroindustrial wastewaters of pineapple, tapioca, tofu industry, and palm oil as well as a conventional acid solvent such as HCl, H2SO4, and CH3COOH).  The incubation process were 0, 1, 2, and 3 month. The results showed that agroindustrial wastewaters that have highest potency for solubizing phosphate rock was industrial tofu wastewaters and followed by industrial wastewaters of tapioca, palm oil, and pineapple. Both the conventional  acid  and  agroindustrial  wastewaters    solvent  have  a  big  potency  for  solubilize  phosphate  rock, however, its highest soluble P-value was not match with the ISO criteria for phosphate fertilizers Quality I (SNI) because it has not reached the solubility of 80% of its total P2O5, but has been qualified as a fertilizer both the quality phosphate A, B, and C (SNI).Keywords: Acidulation, agroindustrial wastewater, P fertilizer, phosphate rock [How to Cite: Ainin N, S Yusnaini and Sarno. 2014.

Abstract

The experiment was conducted to screen potentials indigenous fungi for rapid decomposing of rice straw. Seven isolates ofdominant fungi were isolated from the burying rice straw on the 2.5 cm soil depth after 30 days incubation on the paddy fields. Five dominant isolates were tested for their potential to decompose rice straw by assessing their value  decreasing C/N ratio and dry weight ofrice straw. Fungal inoculums treatments were arranged in a Completely Randomized Design with four replications. The results showed that the dominant cultivable fungi thatisolated from decomposed rice straw were Trichoderma sp., Fusarium sp., Mucor sp., Aspergillus sp., and Penicillium sp. Among the tested fungi, Trichoderma sp. had the biggest ability to decompose rice straw compared to others indigenous fungi. The C/N ratio was reduced to 39.47 from an initial value of73.33 ofcontrol treatment in 10 days ofbiodegradation process in laboratory scale, thus showing the potential of indigenous Trichoderma sp. for use in large-scale composting ofrice straw.

Abstract

Ultisols have poor soil characteristics, yet biochar is one of the technologies that can be applied as a soil enhancer to improve the soil quality. Biochar has succeeded in improving soil quality, through improving soil physical, chemical, and biological properties. This research aimed to improve the quality of soil chemical properties and growth of maize plant, as well as to find a combination between biochar type and dosage of biochar that is able to improve the chemical properties of Ultisols and/or the growth of maize plant. This research was conducted at the Greenhouse and Soil Science Laboratory, Faculty of Agriculture, University of Lampung. This study used a randomized block design (RBD) arranged in factorial with 3 factors and 3 replications. The first factor was the soil layer (topsoil and subsoil), the second factor was the type of biochar (biochar of cocoa shell and biochar of oil palm shell), and the third factor was the biochar dosage (0, 10%, 20%, and 30% of 10 kg of oven dry weight soil). The results showed that (1) the application of biochar from the  cocoa shell and oil palm shell on Ultisols improved some parts of soil chemical properties, namely CEC, organic C, and Kexc, (2) application of biochar from the cocoa shell and oil palm shell on Ultisols increased the plant height, the number of leaves, and the dry weight of maize, (3) application of biochar from the cocoa shell at a dosage of 20% was significantly improved CEC of Ultisols (4) application of biochar from the cocoa shell in top soil at a dosage of 30% significantly improved the soil organic C of Ultisol, (5) application of  biochar from cacao shell at a dosage of  30%  was significantly improved Kexc, (6) application of biochar from oil palm shell at a dosage of 10% significantly increased maize plant growth.

Abstract

Earthworms are important soil biota that can be used as  an indicator of soil fertility. Soil tillage systems and application of organic mulch will affect the activity of earthworms. This research was aimed to study the effect of tillage systems and the application of in situ mulch, and their interactions on the population and the biomass of earthworms. The study was conducted from April to July 2017 at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The study was arranged in a Randomized Block Design (RBD) in a factorial treatment with two factors.  The first factor was the tillage system  which consisted of the minimum tillage and the intensive tillage. The second factor was the application of in situ mulch, which consisted of the application of 0 Mg ha-1 or without mulch and the application of 5 Mg ha-1  in situ mulch.The data obtained were tested for homogeneity of variance with the Bartlett Test and its additivity with the Tukey Test. Data were further analyzed for the analysis of variance and for the LSD’s Test at the level of 5%. The relationship between soil temperature, soil moisture content, soil organic-C and soil pH with population and biomass earthworm was tested by correlation test. The results showed that the earthworm population and the earthworm biomass at 80 DAP in the minimum tillage  was higher than that of the intensive tillage. The earthworm population for all detected planting stages (before tillage, 40 DAP and 80 DAP) with the of application of 5 Mg ha-1 in situ mulch was higher than that of the application of no mulch.  There is no interaction between the tillage system and the application of in situ mulch at 0 DAP, 40 DAP, and 80 DAP.  The genus of earthworms found in all treatment plots was genus Pheretima under the family of Megascolecidae.
