Abstract

This study is aimed to test the hypothesis that the soil quality of sugarcane plantations closely linked to the particulate organic matter (POM) and earthworm’s populations. The research was conducted at five sites in Malang, East Java. The sites were selected based on differences in average annual rainfall and two types of soil management : with and without organic input. Soil samples taken from a depth of 0-20 cm were analyzed total organic C (TOC), total N, POM-C, and POM-N and earthworm’s population density and biomass. The TOC were corrected by the clay  content using pedotransfer equations so obtained TOCref. The interaction between differences in annual rainfall and two types of the treatments significantly (p

Abstract

Agroforestry systems under rules of community-based forest management support local livelihoods in  the Jangkok watershed, Lombok Island. One of the conditions from the forest authoritiesfor allowing  agroforestry system is that it should maintain forest conditions. Since 1995 the Jangkok watershed has undergone rapid land use change, especially in the forest area. These changes led to a reduction of carbon stocks and thus to emission of CO2. This research aimed to: (1) Measure the carbon stocks in several land use system within the Jangkok watershed, (2) Assess the contribution of agroforestry systems in maintaining carbon stocks and reducing emissions. The assesment was performed based on the RaCSA (Rapid Carbon Stock Appraisal) method using three phases: (1) Classify land use change applying TM5 Landsat Satellite images for the period 1995-2009, (2) Measure carbon stock in the main  land uses identified, (3) Quantify the contribution of agroforestry practices. Results showed that (1) The total amount of carbon stock at Jangkok watershed (19,088ha) was 3.69 Mt (193 Mg ha-1); about 23% of this stock found in the agroforestry systems (32% of the area),(2) Gross CO2 emission from the Jangkok watershed was 8.41 Mg ha-1 yr-1, but due to the net gain in agroforestry of 2.55 Mg ha-1 yr-1 the net emission became 5.86 Mg ha-1 yr-1 Keywords:  agroforestry, carbon stocks, carbon emission rate

Abstract

Earthworms population in the soil are greatly impacted by agricultural management, yet little is known about how the quality and quantity of organic matter addition interact in sugarcane cropping system to earthworm population. This study describes the effect of various organic matter and application rates on earthworms in sugarcane cropping system. Earthworms were collected in April, July and December from 48 experimental plots under five kinds of organic matter application : (1) cattle manure, (2) filter cake of sugar mill, (3) sugarcane trash, (4) mixture of cattle manure+filter cake, and (5) mixture of cattle manure+sugarcane trash. There were three application rates of the organic matter (5, 10, and 15 ton ha-1). The treatments were arranged in factorial block randomize design with three replications and one treatment as a control (no organic input). Earthworms were collected using monolith sampling methods and hand-sorted from each plot, and measured its density (D) (indiv.m-2), biomass (B) (g m-2) and B/D ratio (g/indiv.). All the plots receiving organic matter input had higher earthworm density, biomass, and B/D ratio than the control. The highest earthworm population density was found in the plot receiving application of sugarcane trash (78 indiv.m-2) and the mixture of cattle manure+sugarcane trash (84 indiv.m-2). The increase in application rates of organic matter could increase the earthworm density and biomass. Earthworm population density also appeared to be strongly influenced by the quality of organic matter, such as the C-organic, N, C/N ratio, lignin, polyphenols, and cellulose content. Earthworm preferred low quality organic matter. It was caused by the higher energy of low quality organic matter than high quality organic matter. Our findings suggest that the input of low quality organic matter with application rate as 10 ton ha-1 is important for maintaining earthworm population and soil health in sugarcane land.Keywords: earthworms, organic matter quantity, quality, sugarcane cropping system

Abstract

The cultivation of tobacco is one of users of agro-chemical substances such as insecticides, herbi-cides, defoliants, and fertilizers among other food crops and plants with high economical value. The use of these chemicals may bring negative effects regarding the richness and abundance of arthropods. The study of arthropod community in the Virginia tobacco ecosystem was carried out in Central Lombok, West Nusa Tenggara Province, during the 2010 plantation year. It was aimed at finding the composition, structure, and dynamic of the arthropod diversity around the tobacco field. Samples were obtained by using trapping techniques (pitfall traps, yellow-pan traps, and sweep net). The number of arthropods found in Virginia tobacco field are 69, consisting of 65 species of insects (belonging to 46 families and 8 orders) and 4 species of spiders (belonging to 4 families). The majority of insects found was Hymenoptera, dominated by bees. Based on the ecological functions, the major group of arthro-pods documented was phytophagous (20 species), mostly Coleoptera and Orthoptera. Yet, the number of predators was relatively more abundant than that of the phytophagous. The number of kinds of ar-thropods commonly interacting around the field fluctuated during the growing period, while in the cultivation period the number decreased. The diversity of the species (H) and the ratio of abundance of the natural enemies and phytophagous in the field was high.

Abstract

Sugarcane development in Indonesia has shifted to dry land to meet the needs of the national sugar. However, there are many limiting factors like sandy texture, loose structure, low water holding capacity and low nutrient availability that are required to be solved improve to support plant growth and production. Application of soil conditioner is one of the ways to improve the physical properties of a sandy soil. This study was aimed to examine the benefits of sugarcane trash biochar, boiler ash, sugarcane trash compost, and manure as an alternative soil conditioners to improve some of the physical properties of sandy soil and its relationship to the growth and production of sugarcane. Treatments tested in this study were P0= control (without soil conditioner), P1= sugarcane trash 10 t ha-1, P2 = sugarcane boiler ash 10 t ha-1, P3 = manure 10 t ha-1, P4 = sugarcane trash compost 10 t ha-1, and P5 = sugarcane trash 5 t ha-1 + manure 5 t ha-1. The results showed that all treatments increased aggregate stability with very significant compared to the control at 5-11 months after planting. The best results were shown by the treatment of 10 t ha-1 of sugarcane trash biochar that could consistently improve sandy soil aggregate stability at 5-11 months after planting. Application of biochar and others soil conditioner also significantly affected  soil bulk density, pF 4.2, available water content, penetration resistance, Lrv, plant height, stem diameter, although they did not consistently occur in the entire observation period. Overall effect of sugarcane trash biochar and others soil conditioners to physical properties of sandy soil had no effect on increasing the growth and production of sugarcane.

Abstract

Reclamation of ex-mining land is important in restoring environmental conditions approaching the original soil conditions before mining. The aim of this study was is to observe the effect of organic matters and organic matter placement on soil fertility in an effort to improve growth of Merbau (Intsia spp. (L bijuga, L palembanica) and Sengon Buto (Enterolobium cyclocarpum) trees. The study was conducted on a former mining land area of PT. Bukit Asam, South Sumatra. The experimental design used in this study was factorial randomized block design with organic matter factors and organic matter placement. Parameters used for evaluating soil fertility were pH, Al-dd, H-dd, C-organic, total-N, available-P, potential P and K. Parameters of tree growth measured were height, diameter, number of leaves and number of branches and roots. The results showed that organic matter had significant effect on soil fertility and could increase the rate of tree growth and root development. The use of oil palm empty fruit bunch compost significantly increased soil fertility. Results of this study explained the positive relationship between soil fertility with the growth of young trees.

Abstract

Mycorrhiza is a symbiotic fungus with plant roots that is useful for transferring nutrients to plant roots. Potato (Solanum tuberosum L.) is a good host for mycorrhizal growth. Intensive cultivation of potatoes can result in land degradation due to land clearing that does not follow conservation rules, which may lead to a decrease in productivity of potato. This study focused on management of cultivation by occurrence erosion affecting potato cultivation system, and its effect on diversity of mycorrhiza for potato production in an Andisol of Batu. This study usea a completely randomized design factorial with 2 factors: (1) geotextile (2) organic mulch, obtained 24 treatment combinations and 3 replications. Organic mulch doses administered at each treatment were equivalent to 10 t ha-1. The results showed that biogeotextile application had a significant effect on population diversity of mycorrhiza that increased diversity and root infection 10% more compared without application that had no significant effect. The existence of biogeotextile affected soil chemical properties in the form of soil organic matter that increased 2-fold compared with no application. Biogeotextile could increase tuber diameter by 43%, number of tubers by 67%, and potato tuber weight 2 times than without application. The treatment of elephant grass gave the best influence on potato production.
