Abstract

Mount Merapi is most active volcano and periodically erupted. The erupted materials are soil parent materials which rich of base cations that useful for plant growth. Leaching process was used as alternative approach to study base cations released. Leaching experiment used artificial rain water. The effort to reduce base cations leached and also increase base cations relesed was using chicken manure, leucana litters, and Arachis pintoi that used as cover crop as the treatment of experiment. The leaching experiment simulated 4 years rainfall intensity. After incubation for 96 days (4 years rainfall simulation), addition of chicken maure and leucana litters decreased base cations leached in Mount Merapi pyroclastic materials, except for K+ by 16%. Planting Arachis pintoi decrease base cations leached in Mount Merapi pyroclastic materials by 13% but did not increase base cations released.Key words: pyroclastic, leaching, base cations

Abstract

Flood is a major disaster which often occurred in last decade. Generally, land management in upper watershed is the main driving factor that cause flood. Upper watershed area should be intended for catchment area, but in fact land use change from natural forest become agriculture practices continuously happened. This research was done in September-October 2008 in Sumber Brantas sub watershed, City of Batu and some part of Malang Regency. Spatial analysis and land maping was done in Geographic Information System Laboratory of Soil Science Department, Brawijaya University. The objective of this research was to estimate troubled area of flash flood distribution. The parameters were:river flow discharge, slope, distance from river & elevation. The predicted river flow discharge was compared to actual river flow discharge and stastistically tested using doubled regression. This was done to know the accuracy of the model. River flow debit assessment using 15 micro sub watersheds with Thiessen Fraction Distribution (TFD-micro watershed) treatment result the most accurate river flow debit compared to field measurement. River flow debit assessment using one watershed with Average Thiessen (AT-watershed) treatment result lower accurate compared to TFD-micro watershed. In AT-watershed treatment river flow debit result is slightly close to measurement, but there are a significant difference in July and August. The worst result of the validation is the method using 15 micro sub watersheds with Average Thiessen. This caused by rainfall distribution which was used as input data was inappropriate with micro sub watershed distribution in Sumber Brantas sub watershed area. Totally the troubled area of flash flood based on troubled river area of flash flood is as much as 202.23 ha. Troubled area of flash flood is located in 4 Sub Regency, they are: Batu sub- regency as much as 29.39 ha, Bumiaji sub-Regency as much as 164.43 ha, Junrejo sub-Regency as much as 6.08 ha and Pujon sub-Regency as much as 2.43 ha.

Abstract

Forest conversion to coffee agro forestry has decreased quality and amount of litter fall, increase decomposition rate and litter fall mineralization. This research was aimed measuring soil nitrification rate by addition of forest, coffee based agro forestry with mix shade trees and legume-shaded coffee (Gliricidia sepium) and monoculture of coffee litter fall. This research that was conducted in May-June 2005 used Inceptisol  and litter fall of forest, coffee based agro forestry with mix shade trees and legume-shaded coffee (Gliricidia sepium) and monoculture of coffee from Bodong, Sumberjaya, Lampung Barat. Litter fall was collected by litter trap. This research was compiled in a completely randomized design with aerobic incubation method during 8 week in laboratory by 5 treatment addition of forest, coffee based agro forestry with mix shade trees and legume-shaded coffee (Gliricidia sepium), monoculture of coffee litter fall and control (non litter fall addition). Measurement conducted adding litter fall and soil has incubation during 2 weeks. Soil nitrification rate determined by comparing concentration of NH4+ and NO3- after added of litter fall. Data analysis was used one-way. Result of research showed that (1) addition of litter fall has significant (p<0.01) to concentration of NH4+ and NO3- - and N-mineral of soil (2) addition of litter fall has significant (p<0.01) to NH4+ /NO3- ratio (3) addition of coffee monoculture litter fall has yield concentration of NO3- higher than forest and coffee based agro forestry with mix shade trees litter fall (4) addition of coffee monoculture litter fall has yield ratio of NH4+ and NO3- lower (0.1mg kg-1) than addition of forest litter fall (1mg kg-1), coffee based agro forestry with mix shade trees litter fall (0.4mg kg-1) and legume-shaded coffee (Gliricidia sepium) litter fall (0.8mg kg-1). This result of research indicated that adding litter fall like forest, coffee based agro forestry with mix shade trees and legume-shaded coffee (Gliricidia sepium) litter fall can depress soil nitrification rate until 96%.

Abstract

The addition of organic fertilizer into soil increased earthworm growth and its activity and, not only for decomposer group but also for soil digger group (ecosystem engineer).Pontoscolex corethrurus is one of ecosystem engineer group create many channel in soil, so that increased soil porosity and infiltration in soil The objective of this research was to study on N leaching in various biopores condition which formed by earthworm`s activity. Various level of soil porosity and nitrate consentration at controlled condition was obtained from application of  mixture of 3 types of litter (coffee, Gliricidia and durian), N-urea fertilizer and soil digger earthworm (Pontoscolex corethrurus) into soil.  The treatments tested were (1) KO : Control 1 (without worm, N-Organik and N-Anorganik); (2) KCC : Control 2 (added earthworm, without N-Organic and N-inorganic); (3) UREA : (added earthworm + N-inorganic, without N-Organik); (4) KGD : (added earthworm and N-Organic, without N-inorganic); (5) KGDU : (added earthworm + N-inorganic + N-Organic). Each treatment was repeated four times. The biopores formed by earthworm was measured  from the length of soil channel  at 1st, 2nd, 4th, 6th and 8th weeks after treatments (WAP). Measurement on earthworm`s growth was conducted with measuring earthworm`s length, diameter, biomass and casting by the end of treatment (8 WAP). Analysis of nitrate in leachete was done at 2nd, 4th, 6th and 8th  WAP. Result of this research showed that application of N-anorganic only led to more active earthworm rather (83 %) than application of N-organic resulting longer vertical channel formed by earthworm.  However, the increasing the length of vertical channel was not followed by increasing of water percolation. Porosity was related to nitrat leached concentration (R2 = 0.36). Total of leaching was not only influenced by porosity but also by another factor like NO3- -available (influence by N source input). Application of N-anorganic increased concentration of leached NO3- (42 %) than application of N-organic (181 mg L-1 concentration of leached NO3-). No significant (p>0.05) correlation between soil porosity and earthworm`s biomass was found.

Abstract

Levels of heavy metals in agricultural land can be reduced and neutralized with an inexpensive method, known as phytoremediation. The purpose of this study was to learn and know the ability Lindernia crustaceans, Digitaria radicosa, and Cyperus rotundus as fitoremediator for soil contaminated by gold mining waste containing mercury and its effects on growth and yield of maize The study was conducted in a glasshouse with sixteen treatments consisted of three plant accumulators, two soils contaminated with mercury, and two levels of organic matter application. The parameters measured were plant height, number of leaves, dry weight, crop N uptake,  Hg content, and uptake of Hg. The results showed that 10% of tailings contaminated soil (T1) contained Hg less than 20% of tailings contaminated soil (T2). The addition of organic material could assist in providing the nutrients needed by plants to improve soil fertility, so the potential for increased uptake and could reduce the content of Hg in tailing contaminated soil. Lindernia crustacea, Digitaria radicosa, and Cyperus rotundus are potential in reducing mercury concentration in tailing contaminated soils that in turn improved maize growth.

Abstract

In one toposequence, soil moisture available at each location will be different. Soil moisture difference is due to many factors, either environmental factors as well as the ability of soil. Because soil moisture is the water available in the soil that can be used by plants, so the difference soil moisture conditions at each location will cause the carrying capacity of land to support a land use will be different. The research was conducted on the northern slopes toposequence of Mount Kawi, administratively located in the village Bendosari, Pujon, Malang, East Java. The purpose of this study to examine the effect of topography for soil moisture available on northern slopes toposequence of Mount Kawi. Site observations this study divided into five locations by ortophoto northern slopes toposequence of Mount Kawi 1984. The results showed that the bulk density, organic matter, micro pores and meso pores positive effect on soil moisture available, while silt and clay particles negatively effect. Great influence exerted on each factors is different, the highest influence is bulk density which amounted to 29,49% and the decline in organic matter 0,642%, micro pores 0,5509%, meso pores 0,3931 %, silt particles 0,2595% and clay particles 0,2753%. In one row of topography is associated elevation with slope apparently affects the soil moisture available at the study site.

Abstract

Forest conversion to agriculture systems leads to change on litter input (quantitatively and qualitatively) resulting lower diversity, population density and biomass of earthworm. Litter with ratio C/N <20, or ratio of (lignin (L)+polifenol (P))/N <10 classified as high quality which decomposed rapidly. Six types of litter application were tested i.e. prunning of cofee with the lowest (L+P)/N of 7.5, Gliricidia (L+P)/N of 10, avocado with (L+P)/N of 31, Cofee+Gliricidia with (L+P)/N of 12, Cofee+Gliricidia+ avocado with the highest (L+P)/N of 64. As control soil without litter application was used. Applying tree litters regardless their quality increased significantly (p<0.05) all growth parameters of earthworm, except for Gliricidia application lead to higher level of earthworm mortality starting at 20 days after treatment. Applied a low quality of avocado litter to the soil produced the highest biomass (0.79 g/indiv.), diameter (2.42 mm/indiv.) and length (6.13 cm/indiv.). Mixing coffee litter with Gliricidia litter increased earthworm mortality (5.5% to 42.5%) and reduced production of cocoon (2 become 0 cocoons) compared to coffee applied alone. Coffee+Gliricidia+Avocado lead to longer live earthworm up to 80 days Apparently Gliricidia litter producing chemical substances which harmful to earthworm.Keyword: earthworm, litter quality, forest conversion

Abstract

Increase population of people who followed by increasing need for people every year, can indirectly lead to landuse changes and global climate changes. Landuse changes and global climate changes can lead to dryness of the land. Droughts can be analyzed with remote sensing and GIS (Geographic Information Systems). This research is to predict spatial distribution of land droughts and its area using remote sensing and GIS technology based on soil moisture. The research was conducted in Tuban, East Java in January 2013 - April 2013. Method used in this research is a statistical approach using nonlinear regression analysis between index (NDSI, NDVI, NDWI) with a water content of soil moisture estimation models to get the land area of Tuban which is then used as a basis for spatial interpolation. Estimation the distribution of land drought is analyzed based on validation data from soil moisture imagery with pF 2.5 and pF 4.2. Extrapolation of the data is carried out by Land Unit Map pF, then classified into three classes, namely class dry (wilting point condition), humid class (available water content), and wet grade (water saturated). Results show the Permanent wilting point condition is most commonly found in almost all districts with an area of Tuban 109,111.05 ha or 55% of the total area of Tuban. Water conditions are available are found in the west as in the district of Tuban regency Kenduran and Jatirogo and has an area of 20861.82 ha or 11% of the total area of Tuban. While the water saturated conditions are found in the District Plumpang, Widang, and Cross and has extensive 8951.22 ha or 4% of the overall total of Tuban.Keyword: water content, remote sensing, GIS

Abstract

Paddy soil processes and puddling caused by soil formation processes in paddy soil is different with in dry soil. This research aimed to determine the differences of characteristics and soil classification on dry land and paddy soil in Perak Dystrict Jombang. There are 6 soil profile which is involve 3 soil profiles in dry land and 3 soil profiles in paddy soil have been described in the field, after that the soil sample have been taken to soil physic and chemical analysis. Research shown that dry land and paddy soil have a different of soil characteristic (morphologies, physics and chemicals), also soil classification. Morphologically, change occure at the horizon arrangement, colours and plow pan (Adg) form in the paddy soil profile. Differences of soil physic are soil structure, bulk density also consistency. Paddy soil usually have a content cation exchange capacity (K+, Na+, Ca2+ dan Mg2+), C-Organik and base saturation that higher than dry land. Soil classification in dry soil and paddy soil different start at the sub order, as a result of changes in soil moisture regime from ustic to be endoaquic in paddy soil.

Abstract

Land degradation in the Cassava causing damage to land, especially land due to the loss of part of the place. The loss of this part of the land causes a decrease in soil productivity, loss of the elements required burly plants, infiltration rate and water holding ability of soil is reduced, and the land use of opium. This condition will result in halted plant growth and decrease harvest. Various kinds of soil conservation activities has long been introduction by the government. However, results are still unsatisfactory. Not many farmers who adopt conservation technology, the government introduced the land, and land degradation continues.This  research is to learn how different the various technical maintenance of the nature of the soil, the plants, and erosion and find out the pattern of land the right to increase the plant Cassava. Reduction in erosion rate occurred as a result of improvements to the land and the nature of plant growth. Research conducted in the Garden Experiments Brawijaya University in Malang. Ordo Alfisols including land, land and cycle 6 - 8%. Maintenance of land is done with the form of organic manure, and soil processing. Results of research shows that, technical maintenance of good soil is able to increase plant growth. As a result of improvements to decrease the growth of plants and limpasan level erosion surface. In the election technology, farmers choose tumpangsari treatment combination of manure and gulud as possible options.Keyword: land husbandry, cassava, land management, crops, erosion.
