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.

Excessive utilization of natural resource by human being will affect the sustainability of agriculture, land and environment. This is due to degradation of soil physical properties in the area. A research about study of soil physical properties had been taken out in a sub-sub watershed Batanang of Sumpur watershed, Batipuh, Tanah Datar Regency, in West Sumatra. The research was conducted by surveying the area in 2006. Disturbed and undisturbed soil samples were taken in different land units. Then, soil samples were analysed at soil laboratory, Agriculture College, Andalas University Padang. The result showed that all of land units in this sub sub watersehed had the same soil texture class, that was fine clay. The bulk volume of the soil was higher in Mixed woodland unit than those in forest land units. Permeability value of the soil was higher at forest from all degrees of slope than that at mixed woodland, even though soil organic matter content of mixed woodland unit higher than that at forest with 25-45% slope.Keywords: Sub watershed (DAS), forest, land unit, soil physical properties

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

A study about sediment content and nutrient movement was conducted in Sumpur watershed, Tanah Datar Regency, West Sumatra. The objective of the research was to determine sediment content and nutrient movement on Sumpur watershed and the relationship. Survey method by sampling water in joining river was employed to this research for sampling water. Water was sampled exactly after rain or at the time of river debit was maximum and without rain as a control. Water flowing into the river comes from several lad uses in the upper watershed. There were four types of land use found in the areas, those were forest, mixed garden, annual season crops, and rice field. Based on field observation it was found that there were two classes of soils there, Andisols and Inceptisols. The results of laboratory analyses showed that river current, soil consentration in river water, as well as sediment content were linearly correlated to rainfall amount. Positive linear correlation was also found between river debit and carried nutrients (N, P, K, Ca, Mg, Na) from the research area. Keywords: watershed, rainfall, sediment carried, and nutrient carried

A research about amelioration of psycho-chemical of Psamment by using organic mulch and techniques of conservation tillage on corn growth had been conducted in 2009. Field experiment was located in Korong Olo Bangau, Batang Anai, Padang Pariaman Regency. The general objective of the research was to improve fertility of Psamment and to find out the best tillage practice for corn growth based on soil and water conservation rules. The treatment consisted of two factors (3 x 5) which was designed in RBD. The first factor was tillage (No till, Minimum till, convensional till) and the second factor was mulch source (without mulch, Tithonia, Chromolaena, rice straw, and corn straw). Parameters analysed were either soil physical (moisture, BD, total pore, aggregation) or chemical (pH, N, P, and K) properties, as well as crop production. The result showed that both treatments were able to improve soil-physico-chemical properties of Psamment and corn yield. The value of BD decreased, soil organic mattere, total pore, and aggregation increased. Then, the soil pH as well as available P and K tended to increase. The highest yield (dry seeds) was found from combination between minimum tillage and tithonia mulch.Keywords: sifat fisiko-kimia, Psamment, mulksa, olah tanah konservasi, jagung.

Earthquacke on 30th of September 2009 in West Sumatra had ruined Padang Pariaman, Agam, and Padang city districts. The damage was not only caused by the earthquake itself but also due to the landsliding following the earthquake, such as in Tandikek. Hundreds of people, houses, buildings, schools, as well as agricultural land (ricefield and dryland farming) were burried in Lubuk Laweh, Kepala Koto and Cumanak. This research was conducted by employing survey method and by observing the phenomenon of tuff pumice on how it was affected by earthquake and water. Then, soil characteristics were analysed based on soil physical data from previous research. Several soil characteristics analysed were soil texture, bulk density, structure and depth of solum, organic matter content, and permeability. Land characteristics were determined through field visit. Some land condition being observed was slope (percentage and length), stone exposed, soil water depth, and land use. Additionally, besides from field visit, the data were also obtained from topography and morphology maps derived from Google Earth. Rainfall data (monthly and annually) were collected from several nearby meteorology stations. Analyses for degree of landsliding risks for an area were used soil and land characteristics criteria causing landsliding. Based on field visit, it was seen that the research area was still susceptible to landsliding. This was due to the parent materials of the soil deriving from tuff pumice which is crumb structure and loamy texture on the top layer. Climate, especially annual rainfall in study site was high enough (approximately 4322 mm) which was evently distributed all year long without dry month. Slope of the area was > 45%, especially areas hit by landsliding. Land use was not based on soil conservation rule, such as coconut and arenga pinneca, and other mixed trees were planted on the area having > 45% slope. The results of the soil characteristic analyses showed that HARKAT interval of lansliding threat was 13 and land characteristics showed 20. Summation of HARKAT values from soil and land characteristics was 33. This number showed that the study site had high degree of landsliding risk. The possibility of areas would be hit by lansliding were Partamuan, Koto Timur, Sungai Geringging, and around Maninjau lake.Keywords : earthquake, soil and land characteristics, tuff pumice, wet tropical
