Abstract

The abundance and biomass of earthworms are affected by soil tillage and fertilization. This research aimed to study long-term 32nd-year soil tillage and nitrogen fertilization on the population and biomass of earthworms under Zea mays L. The research was conducted using a randomized block design (RBD) which consisted of two factors. The first factor was the soil tillage that was Intensive Tillage (IT), Minimum Tillage (MT), and No-Tillage (NT). The Second factor was nitrogen fertilization that was N0 = 0 kg N ha-1 and N1= 200 kg N ha-1. Data of earthworm population and biomass were tested using analysis of variance and continued with the least significant difference (LSD) test at the 95% significant level. The population and biomass of earthworms at MT or NT were higher than IT. The population and biomass of earthworms in the plots without fertilization were higher than those at 200 kg N ha-1. There was an interaction between the soil tillage and N fertilization on earthworm biomass observed 60 days after planting at a 0-10 cm depth. There was a positive correlation between soil pH and earthworm population and biomass before the tillage phase.

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

Efforts to increase the production of sweet corn can be done with the application of fertilizers, either inorganic, organic orits combination. In addition, the application of soil amendments such as biochar is also expected to improve soil fertility that will indirectly increase the production of sweet corn.Organonitrophos fertilizer is an organic fertilizer developed by lecturers of Faculty of Agriculture, University of Lampung. The research was aimed to study effect the combination of organonitrophos, and inorganic fertilizers, biochar and the interaction between fertilizer combination and biochar on soil respiration and soil microbial biomass.The research was conducted in the Integrated Field Laboratory of Lampung University using 6x2 factorial in a Randomized Block Design with 3 replications. The first factor was six levels combination of organonitrophos and inorganic fertilizers (P0, P1, P2, P3, P4, and P5). The second factor was two levels of biochar dosage (B0 and B1). Data was analyzed by Analysis of Variance and followed by the Least Significant Difference (LSD)Test at 5% level. The observed variables were soil microorganism activity likely soil respiration and soil microbial biomass. The results showed that P3B1treatment (300 kg Urea ha-1, 125 kg SP-36 ha-1, 100 kg KCl ha-1 + 2500 kg organoitrophos ha-1) was the highest soil respiration at of 60 days after planting (DAP). P5 treatment (5000 kg Organonitrophos ha-1) has the highest soil microbial biomasscompared to other treatments at 60 and 90 DAP. B1 treatment (5000 kg biochar ha-1) has higher soil respiration and soil microbial biomasscompared to treatment (0 kg biochar ha-1. There was an interaction between combination of organonitrophos and inorganic fertilizers and biochar on soil respiration at 90 DAP. However, there was no interaction between fertilizer combination and biochar on soil microbial biomass.Keywords: Biochar, Fertilizer Combination, Organonitrophos, Soil Microbial Biomass Carbon and Soil Respiration

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

Intergrated Forest for Conservation Education of Wan Abdul Rachman (IFCE WAR) Great Forest Park is a conservation forest zone which has natural area and cultivated area. The natural area in Wan Abdul Rachman Great Forest Park consists of secondary forest, whereas the cultivated area consists of agroforestry with cacao plants and agroforestry with coffee plants. The different land use in both areas caused the difference in carbon sink specifically in litter and soil. The research was aimed to study the difference of litter and soil carbon stock in natural and cultivated area in IFCE WAR Great Forest Park. The observation plots included in the current study was determined using purposive sampling method. The research was conducted in June until August 2015. Data was analyzed using analysis of variance and continued with honestly significant difference test. The results showed that there was no difference of litter carbon stock in cultivated area and natural area in IFCE WAR Great Forest Park, whereas the soil carbon stock in natural area was higher than that in cultivated area.
