Abstract

Oxidation of pyrite in acid sulphate soil reduced the quality of soil. The improvement of soil quality in paddy cultivation could be managed by the addition of organic matter together with regulating water to maintain its reductive condition. The objective of this research was to obtain information on the ability of rice straw compost in improving soil quality and rice production. The research was conducted in acid sulphate soil(Typic Sulfaquepts), with flooding during high tide (B type) at experimental field Belandean, Research Institute for Swamp LandAgriculture (Balittra), South Kalimantan, during dry season of 2003. Treatment for improving soil quality was in the form of the rate of application of rice straw compost. Research results indicated that the application of rice straw compost was capable to improve soil quality during vegetative phase substantiated by increasing soil pH and organic matter content, and decreasing exchangeable Al, and also increasing Fe2+ and SO42- solubility. All of the soil chemical properties determine rice production, and Alexchangeable has the highest correlation. Application of rice straw compost as much as 2.7 t ha-1 (dry weight equivalent) wascapable to increase the yield of rice by 48%. This research results indicated that the rice straw from harvest should be returned to the paddy soil.

Abstract

Abstrak. Penelitian ini bertujuan untuk menganalisis stabilitas agregat tanah dengan perlakuan berbagai isolat bakteri pemantap agregat (BPA) dan bahan organik berupa kompos yang terbuat dari campuran 90% rumput Cyperus pilosus Vahl dan 10% kotoran sapi, dengan masa inkubasi yang berbeda. Taraf perlakuan terdiri dari kontrol, kombinasi isolat I, II, dan III masing – masing dikombinasikan dengan komposisi bahan organik 0%, 0.5%, dan 1%. Hasil penelitian ini menunjukkan aplikasi isolat BPA pada tanah pasir berlempung disertai pemberian bahan organik menyebabkan populasi yang lebih tinggi dibandingkan tanpa aplikasi keduanya. Klebsiella sp. LW-13 yang dikombinasi dengan 1% bahan organik dan Bukholderia anthina MYSP113 yang dikombinasi dengan berbagai taraf bahan organik (0 hingga 1%) menyebabkan agregat menjadi sangat mantap sekali pada pengamatan 60 hari setelah aplikasi. Eksopolisakarida yang dihasilkan bakteri akan mengikat partikel tanah dan membentuk agregasi. Penggunaan bakteri Bukholderia anthina MYSP113 dinilai lebih efisien dalam pemanfaatannya untuk memantapkan agregat tanah karena memiliki kemampuan terbaik untuk memantapkan agregat tanah hingga sangat mantap sekali dengan atau tanpa penambahan bahan organik pada periode 60 hari pengamatan.Abstract. This study aimed to analyze the aggregate stability of soil with sdifferent treatments of aggregate-stabilizing bacteria and organic matter (compost made of mixture of 90% Cyperus pilosus Vahl grass biomass and 10% cattle manure) at different incubation period. Treatments consisted of control, combination of three different isolate with three different composition of organic matter (0%, 0.5%, and 1%). The results showed that the application of aggregate-stabilyzing bacteria to loamy sand soil and organic matter causes a higher bacteria population than without both applications. Klebsiella sp. LW-13 combined with 1% organic matter and Bukholderia anthina MYSP113 which was combined with various levels of organic matter (0 to 1%) showed high aggregation at observation of 60 days after application. The exopolysaccharide produced by bacteria binds soil particles and forms soil aggregation. The use of Bukholderia anthina MYSP113 bacteria is considered to be efficient in its utilization to stabilize soil aggregates because it has the best ability to stabilize soil aggregates to be highly stable with or without the addition of organic matter in the 60-day observation period.

Abstract

Comparison of two method on calculating runoff coefficient (Cr), is discussed in this paper i.e. classical method and alternative method. The first one calculates Cr based on the hydrograph separation analyses, and the second one based on the discharge model simulation by applying unit hydrograph concept. The classical Cr values is calculated using simple method and the alternative Cr values is calculated using H2U (Hydrogramme Unitaire Universel) transfer rainfall-discharge model, for 47 rainfall and discharge events from September 1998 to March 1999 on Kripik sub Watershed. The H2U model calculates discharge based on convolution product between excess rainfall and hydrological network density that was represented by probability density function. The Cr value according to this model is determined when the Cr is resulting the best discharge simulation. During the period of September 1998 to March 1999, the classical Cr value varied between 2,8 to 69,1%, while alternative Cr between 1,0 to 48,8%. The smallest and the biggest differences between classical and alternative Cr values were 0,3% and 26,5%, respectively. According to regression analyses and Nash-Sutcliffe criterion, the coefficient of determination (R2) and the coefficient of efficiency (F) were 0,9312 and 0,6829, respectively. Statistically, these values indicate that the alternative Cr value was similar to classical one.

Abstract

The management of nucleus smallholder oil palm after conversion is mostly improper with the promoted management practice, consequently oil palm yield decreases due to decreasing of land quality. For this reason, the study has been done to characterize land condition, to assess land suitability for oil palm and to correlate soil properties against oil palm yield. The study was conducted at Sei Pagar, Kampar District, Riau Province from January 2007 to March 2008. Soil erosion was estimated using Universal Soil Loss Equation, while land suitability was processed using Land Evaluation Technical Guidance for Agriculture Commodities, and correlation of soil  properties to oil palm yield was calculated using Multiple Regression Analysis on SPSS Version 12.0. The study showed that climate conditions was favorable for oil palm growth and production, with annual rainfall 2,339 mm year-1, air temperature 26.04oC, and relative humidity 81.2%. Soil erosion varied from 1.322-3.423 t ha-1 year-1. The soils were dominated by Typic Haplosaprist and Terric Haplosaprist covering 8,641 ha with land suitability of S2-f (moderately suitable with nutrients retention as limitng factor). The other soil are Humic Dystrudepts and Typic Dystrudepts covering 587 ha with land suitability of S2-f,n (moderately suitable with nutrients retention and nutrient supply as limiting factors). The soil properties of Typic Haplosaprist and Terric Haplosaprist affected to oil palm yield are organic-C, nitrogen content, P2O5 content, and available-S. Meanwhile, on Humic Dystrudepts and Typic Dystrudepts, oil palm yield was affected by organic-C, nitrogen content, available-S, and aluminum content.

Abstract

In relation to land management and sustainable environment quality, soil degradation is considered as important issue. Soil degradation could be appropriately overcome when the characteristics of restoration or its resilience are recognized. The main purpose of this research is to characterize and classify upland degraded soils in Central Kalimantan based on land quality (LQ) that determine land suitability classification within landutilization type (LUT). The parameters of LQ involve water availability (w), nutrient availability (n), Al toxicity (t), soil resistance to erosion (e), and antropogenic soil deterioration (d). While, for LUT, there are several types i.e. rice; rice-rice-soybean; rubber; and oil palm within three patterns A, B, C. The other purpose is to characterize and classify degraded soils and soilresilience based on land index and land suitability classification. The parametric reffering to land index taken from production of commodity estimation within each LUT based on land quality is used to classify land suitability. Research result shows that Alfisols has the highest soil capability. It is indicated by land index that is higher than the other soils. The main indicators of soil degradation and resilience involve LQ of nutrient availability, water availability, and Al toxicity. The high soil potency does notshow the ability of resilience. On the other hand, the low soil potency cannot be able to keep sensitivity of degradation. The resistency of soils at study area is relatively high. Generally, degraded agricultural land region is difficult to be conserve through natural revegetation period known as bare land. Both natural and antropogenic resilience are not quite different atupland soils in Central Kalimantan. Soil taxa cannot reflect the difference of degrada

Abstract

Abstrak. Drainase lahan gambut diperkirakan akan mempengaruhi populasi dan keanekaragaman hayati di tanah gambut. Tujuan dari penelitian ini adalah untuk mengevaluasi pengaruh drainase dan tutupan lahan gambut di Tanjung Jabung Timur, Provinsi Jambi terhadap populasi dan keanekaragaman mikroba tanah gambut. Sampel tanah gambut diambil dari tiga lokasi yang berbeda yaitu: (A) perkebunan sawit dengan kedalaman saluran drainase 50-70 cm, (B) perkebunan sawit dengan kedalaman saluran drainase 20-50 cm, dan (C) hutan gambut. Total populasi mikroba dihitung menggunakan metode Total Plate Count dan media selektif pertumbuhan bakteri, fungi, dan aktinomicetes. Mikroba yang memperlihatkan tampilan fisiologis yang berbeda masing-masing dihitung populasinya, lalu dilakukan identifikasi menggunakan Biolog Identification Kit. Hasil penelitian menunjukkan bahwa total populasi dengan keragaman mikroba tertinggi terdapat pada contoh tanah gambut yang telah didrainase pada kedalaman tanah 0-20 cm. Bakteri penambat nitrogen Azotobacter hanya terdeteksi pada tanah gambut lapisan tanah 0-20 cm di lokasi A. Mikroba pelarut P dengan total populasi 2,00 x 104 - 4,00 x 104 cfu g-1 terdapat di tiga lokasi, tetapi hanya ditemukan pada kedalaman 0-20 cm. Pada tanah gambut di lokasi A di kedalaman 0-20 cm dijumpai delapan jenis mikroba, yaitu: Azotobacter sp., Bacillus luciferensis, B. salarius, B. soli, Cupriavidus paucalus, Mycobacterium cubhense, Paenibacillus illinoisensis, dan P. wynnii. Sedangkan pada kedalaman 20-50 cm diperoleh spesies bakteri yang lebih sedikit, yakni Bacillus kribbensis, Bacillus panaciterrae, Chryseobacterium balustinum, dan Paenibacillus peoriae. Pada lokasi B, jenis mikroba yang dijumpai lebih sedikit dan didominasi oleh enam spesies bakteri (Bacillus salarius, B. soli, Cupriavidus paucalus, Nocardia jiangxiensis, Paenibacillus wynnii, dan Pseudomonas aeruginosa), sedangkan di lokasi C didominasi oleh hanya lima spesies mikroba (Bacillus vallismortis, Nocardia jiangxiensi, Paenibacillus glycaniliticus, P. peoriae, dan Rhodococcus equi). Tampaknya drainase dan pemupukan pada lahan gambut di perkebunan sawit mendorong pertumbuhan mikroba.Abstract. Drainage of peat is expected to affect belowground biodiversity. The purpose of this research was to evaluate the impact of drainage and peatlands cover in Tanjung Jabung Timur, Jambi Province on the soil microbial population and the soil microbial diversity. Peat soil samples were taken from three locations, namely (A) oil palm plantation with 50-70 cm drainage channel, (B) oil palm plantation with 20-50 cm drainage channel, and (C) logged-over forest. The total microbial population was calculated using the Total Plate Count method and the selective growth medium of bacteria, fungi and actinomycetes. The population of microbes exhibiting different physiological features were counted and then identified using the Biolog Identification Kit. The results showed that the highest total microbial population and diversity were found in drained peat at 0-20 cm soil depth. Nitrogen fixing bacteria, Azotobacter, was found only in 0-20 cm layer of the A location. P-solubilizing microbes were found only in the 0-20 cm layer peat with the total population ranged from 2.00 x 104 to 4.00 x 104 cfu g-1 soil in the three sites. In the 0-20 cm peat layer of location A, we found eight kinds of bacteria, namely: Azotobacter sp., Bacillus luciferensis, B. salarius, B. soli, Cupriavidus paucalus, Mycobacterium cubhense, Paenibacillus illinoisensis, and P. wynnii. In peat of location B, the total population of microbes was fewer, consecutively dominated by six species of bacteria, namely Bacillus salarius, B. soli, Cupriavidus paucalus, Nocardia jiangxiensis, Paenibacillus wynnii, and Pseudomonas aeruginosa, while in peat of location C was dominated by five species of bacteria (Bacillus vallismortis, Nocardia jiangxiensi, Paenibacillus glycaniliticus, P. peoriae, and Rhodococcus equi). It seems that drainage and fertilization in drained peatlands under oil palm plantations encouraged microbial growth.
