Study about soil organic matter (SOM) leaching in soil profiles of tropical rain forest was conducted in Bukit Pinang-Pinang, the upper footslope of Mt. Gadut in West Sumatra, and in Soil Physical laboratory Andalas University Padang. Bukit Pinang-Pinang is located on 480-640 m asl and geographically is between 100°29’40” and 100°30’20 E” as well as between 0°54’55” and 0°55’45”S. This rain forest area is known as a super wet area because it receives high annual rainfall (>3500 mm). The objective of this research was to measure the amount of SOM leached from top soil into the deeper soil. Undisturbed soil samples were taken from three different land uses, forest, bush, and mixed garden, on the top, middle, and foot slopes. Undisturbed soil samples were leached with distilled water as the amount of rainfall accepted in natural condition. The results showed that, land use change from forest into ecosystems of mixed garden (for over 50 years with 100% soil surface coverage and without any cultivation) and bush land (for over 20 years left) did not cause the SOM content in the profiles decreased. Amount of SOM leached from the top 0-10 cm was found greater from mixed garden, then followed by forest on the upper slope, forest on the middle slope, and bush area.Keywords: SOM leaching, land use change, tropical rain forest, bush, mixed garden

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.

Banana is one of fruit commodity having been widely cultivated by people and has high potency for agribusiness. However, there are some constraints for the cultivation, such as soil fertility and disease attack. Nowadays, tne main disease causing low banana production in West Sumatra is wilt due to Fusarium. One way being developed to improve banana production in endemic land is by using bioagent. This research was aimed to identify spores of mycorrizhae in several endemic land. The result showed that there were various types of MVA found in tested locations (Agam, Solok, and Padang Pariaman regencies). Glomus was one genus that was always found in each location. Therefore, the glomus sp was quite potential to explore and and proliferation as a good innoculant to improve growth of banana plant. The highest amount of MVA sport found in Padang Pariaman regency (especially in Pasar Usang area) was 195/20 g soil (Glomus), then followed by Acaulospora (121 spora/20 g soil) and Gigaspora (65 spora/20 g soil).Key Words: Banana, Fusarium, Wilt, Bioagent, MVA

A research aiming to improve soil aggregate stability of Ultisol in terms of creating sustainable agriculture and environmental development was conducted by applying fresh organic matter (OM) into soil. Three types of OM sources used were Titonia diversifolia, Chromolaena odorata, dan Gliricidia sepium. This research was conducted in Ultisol Limau Manis Sumbar having annual rainfall > 5000 mm, in 2008. The fresh OM used was cut, mixed with soil up to 20 cm depth, and then incubated for approximately one month before corn seeds were planted. Soil was sampled before being treated with OM and then after harvesting corn (4 moths after applying OM). Soil OM content as well as soil aggregate stability (AS) and several other soil physical properties wer analysed in laboratory. The results showed that soil OM content and AS increased after one planting period. Besides that, soil physical properties were also improved. As soil physical properties became better, corn production was also higher at plot with than without OM application. Among 3 species of OM added, Tithonia diversifolia gave highest corn biomass. Level of land slope (0-8% dan 15-30%) did not show significant difference either for biomass or for soil OM content and soil AS.Key Words: marginal soil, green manure, soil aggregate stability, soil organic matter
