The arbuscular mycorrhizal fungi ( AMF ) with plants able to increase the capacity of plants to absorb nutrients and water from the soil. Recently, research was indicated that AMF hyphae containing glomalin as a glycoprotein that serves to unify the dispersed soil particles. The content of glomalin in soil is positively correlated with soil aggregate stability. The research potential of AMF species indigenous of Ultisol Darmasraya District of West Sumatra and glomalin production in experimental pots of sterile sand medium has been carried out. The purpose of this study was to determine the diversity of AMF species on Ultisol and to seeking indigenous AMF isolates that had the best glomalin production capability. AMF spores were isolated and identified from the rhizosphere soil of corn in Ultisol. AMF species that had been identified experimentally were tested in culture medium pot of sand and zeolite (w / w 1:1) using corn crops. The results found nine of the AMF species indigenous of Ultisol Darmasraya, namely Acaulospora scrobiculata, Glomus etunicatum, Glomus luteum, Glomus mosseae, Glomus verruculosum, Glomus versiforme, Scutellospora gregaria, Scutellospora heterogama and Gigaspora sp. AMF species that showed better colonization ability in corn was G. luteum, G. verruculosum and G. versiforme. All three species produced glomalin significantly higher than the other species, i.e. 1.29 mg g-1; 1.17 mg g-1; 1.15 mg g-1, respectively.

Ultisols as a marginal land need to be reclaimed especially the soil aggregate stability (SAS) under wet tropical area. A research about application of 3 types of fresh organic matter (FOM): Gliricidia sepium dan Tithonia diversifolia) aiming to improve SAS was conducted in Ultisol Limau Manis, wet tropical area, West Sumatra. Fresh organic matter was added to soil at 3 different slope (3, 12, dan 25% slope) in early 2008, then the soil was planted by corn for 4 times until the end of 2009. Corn biomass was return to the land as mulch between crop rows every harversting. The land, then, was fallowed for 1 year (in 2010) before the soil was sampled in 2011 for the physical properties analyses. The results showed that soil organic matter (SOM) content, SAS, permeabilitas, and total pore at 0-20 cm soil depth from plots applied with FOM at all classes of slope were still higher than those control plots. From 3 FOM added, plot added with Tithonia diversifolia still showed better soil physical properties (SOM = 8.3%, SAS = 83). It means that FOM application on Ultisol under wet tropical raiforest still gave effect until 3 years after application.Key Words: Ultisol, stabilitas aggregat, bahan organik segar, bahan organik tanah

Mycorrhizal symbiosis increases nutrient uptake for plants, resistance to disease, stabilizes soil aggregates and promotes the growth of soil organisms. Fungal hyphae containing glomalin is essential for soil biological processes because of their interactions with plants, soils, and microbes. Activity of AMF in the area of rhizosphere and mycorizosphere will improve the physical, chemical and biological conditions of the soil, thereby providing a healthy soil environment for plants. How the influence of AMF inoculants plus organic ingredients on growth and production of maize on Ultisol needs to be tested in the field. The purpose of this experiment is the application of AMF plus organic inoculants to corn planting, to determine the effect on growth and increase of corn production. Experiments using a randomized block design with four groups. The AMF inoculation treatment was the administration of organic plus inoculant from G. luteum (F1), G. verruculosum (F2), G. versiforme (F3), Multi species of AMF (F4) and without AMF inoculation (F0). The results showed that AMF inoculation had significant effect on total glomalin. G. versiforme has the highest total glomalin, which is 10.59 mg.g-1. The effect of AMF species had no significant effect on aggregate stability, but was significantly different from the treatment without AMF inoculation. The effect of AMF on N, P and K uptake is significantly different. The highest dry corn kiln production from G. versiforme, which is 8.07 kg / plot or 4.04 ton / ha, has the same effect as G. luteum (7.98 kg / plot or 3.99 ton / ha) and Multi AMF (7.67 kg / plot or 3.84 tons / ha). Increased production of dried corn plants inoculated with AMF plus organics can reach 40-83% higher than the plants without giving the AMF.Key words : mycorizosphere, productivity, rhizosphere, Ultisol

The upper catchment of Batang Hari river in this report is define for the areas of Batang Hari at the end point of Batang Hari Irrigation scheme project at the village of Teluk Kayu Putih of district of Tebo of the Jambi Province up to the Twin lake Of Danau Diateh in the inland areas of Batang Hari river. Covered the areas about 695.400ha which divide to the sixth of sub catchment ie; Momong (41.750ha); Bt. Hari (184.340ha); Sangir (128.660ha); Siat about 45.100ha with divided into small catchment of the Siat river tributaries which main Siat tributary (32.800ha), Piruko/Palangko tributary (7.300ha), Mimpi tributary (5.000ha); Jujuhan (187.300ha) and Pangian (108.250ha). Detail of information showed at Fig. 1 and table 1. Except of sub catchment of Momong, Jujuhan and Pangian, three tributaries already used for irrigation water. The new construction of dam for irrigation scheme are located after joint tributaries of Sangir which flow from Lake Rawa Banto of Mount Krinci and Batang Hari tributary which flow from Lake DiAteh. The length of each main stream Sangir and batang Hari is 118 km and the total length of tributaries conducted of both tributaries is 603km. Based on the hydrological point of view Sangir tributaries is important because these areas high in the annual rainfall. The amount of precipitation of station Liki, Pinang Awan and lubuak Gadang has recorded more than 4000mm annually. The areas could be grouped to the Zone Agroclimatic A of Oldelman. Batang Hari tributaries which average annual precipitation less than 2500mm, these amount is average value of station Alahan Panjang, Surian, and Muaro labuh which each station are differ in the agroclimatic zone, Zone agroclimate C2, D1, and B1 for Alahan Panjang, Surian and Muaro Labuh respectively. The old river terrace of Batang Hari which developed for irrigation scheme has covered the areas on 20000ha conducted areas along the old river terrace of Batang Hari which parts of Siat, Piruko/Palangko, and Mimpi up to the old terrace at cross of the tributary of Jujuhan which main stream. Different elevation between old river terrace with inland areas both Rawa Banto of Sangir and Lake Diateh of Batang Hari is 1300m. Hydrological data of river water discharge by used the value 90% of run off data, which calculate base on the average annual rainfall multiplication by the wide of catchment. These value are not significant different which average 18 years data from 1975-1993 of Automatic Water Level Recording (AWLR). In the value 277m3/det and 284m3/det for average value of AWLR and 90% of runoff value respectively. Compare to the AWLR record in 1975 water discharge is decrease. The data of 1975 is 61% compare to runoff data or 60% compare to average data of AWLR. These indicated that the type of land use of the upper cathment already changed. The amount of discharge has decreases in the value of 40% from the average value as the effect of deforestation during the last 30 years. The hydrological condition also observed at the Siat river. The rate of deforestation could be calculated by using the value of forest contribution to the regional annual budget (PDRB). The validity of the method has needed honesty of the timber company. If the company or government official not fair, for calculation should be used correction factor 50-100 percent. Base on the PDRB data rate of deforestation has calculated in the value of 5000-7000ha/yr. related to the calculation the catchment of Siat, Mimpi, Piruko/Palangko already degraded and Siat river in the dry season especially in August conot open the water intake for irrigation as lack of water discharge. Key words: Rain fall, water discharge, deforestation, and sustainable watershed management

Research on soils fertility of rice soils has been done on three catchment in West Sumatra province ie; Ulu Selo ( inland areas of selo river) at Tanah Datar district conducted three Kenagarian ( traditional village) Simpurut, Gurun, and Padang Laweh. Lembang catcment at Solok district is conducted ubo irrigation scheme ubo which divided as Ubo atas irrigation scheme and Sirukam. Sumpur cathment at East Pasaman District conducted three Kenagarian, Lundar, Petok and Kuamang. All of irrigation scheme located at agroclimatic zone C1 up to D2, with charaterize 2 or 3 consecutive wet month and 3 or 4 consecutive dry month. Soils were developed from volcanic parents materials. Rice soils of Ulu Selo shown lower pH value compared to the soils with land use is mixed garden, which some of the sampling point has shown the pH lower than 4. the rice soils of Lembang and Sumpur also shown the similar trend of pH but the value not so extremely like the soils from Ulu Selo. Related to the minimum value of carbon in rice soils is indicate that some of the rice soils in the research areas could be grouping as degraded land. The rice soils from Sumpur has high natural soil fertility which which shown on the natural reserved of nitrogen, phosphor and potassium. The soils condition could support the rice production up to 8t/ha/ GS without additional nutrient. While soils from Ulu Selo shown lower content of phosphor. Based on this research author suggested to fertilizer program is better done based on the condition of soils itself. Even the natural soils fertility is high is not reccomended to use addtional artificials fertilizer.Key words: cathment studies, natural soil fertility, rice production and land degradation.

Mangrove, as one of the most unique ecosystems, is a great natural resource potential with high productivity and biodiversity able to adapt to harsh areas between the sea and coast. Its destruction rate is very mild as it is estimated to 1% each year (Ong et al., 1991) and 0.7-3% per year (Pedleton et al., 2012). The destruction of mangrove is usually related with human population density (Alongi, 2002). Widespread mangrove destruction affects the loss of biodiversity and other resources and the functioning of the ecosystem. The huge potential of mangrove must be preserved by managing, maintaining and providing costs to protect and improve ecosystems. This study aims to measure Kuala Langsa community members’ willingness to pay for the preservation and repairationof degrading mangrove. To achieve this goal, Contingent valuation methods was used in this study. Of the 131 respondents involved in this study, 112 or 85.496% are willing to pay for the preservation of mangrove. While those unwilling to pay account for 19 or 4.504% . WTP with the households 669 earned by is Rp 18,821,512,200/month or Rp 225,858,146,400/year.

The Batang Kuranji watershed is an area that plays a vital role in the water resources preservation and conservation in Padang city. However, recently the sustainability of these water resources has suffered hydrologically, marked by a sharp fluctuating flood discharge. This study aims to measure the water resources sustainability in the Batang Kuranji watershed. The method used in this research is Nedbør Afstrømnings Model (NAM) modeling and an integrated approach. The results of NAM showed that the most prominent parameter values are TIF (0.9), TG (0.965), CK1 (0.23), and CK2 (1.1), which indicate an infiltration transformation in this watershed. The integrated analysis showed that deforestation and population growth are the main factors for this issue, and the land-use conversion also affected these problems. Reducing the population growth rate, evaluating the urban development, reforestation, and improving water infrastructure along rivers-side will reduce the risk of watershed damage and maintain its sustainability.
