There is no much public concern about soil aggregate stability improvement of a soil. This is due to the fact that it does not directly affect crop yield for a short term, but it determines sustainable agriculture and development for a long term. This research was aimed to investigate soil physical properties especially soil aggregate stability of Ultisols after fresh OM application, then to determine the exact OM dosage to improve the stability. Ultisols used was from Limau Manis (± 367 m asl), an area in lower footslope of Mount Gadut, having wet tropical rainforest. Due to land use change, farming activities in that sloping area could enhance erosion process in the environment. Therefore, efforts to anticipate the erosion must be found. Fresh OM applied was Gliricidia sepium which was found plenty in the area. Five levels of fresh Gliricidia sepium, were 0, 5, 10, 15, and 20 t/ha. Top soil (0-20 cm depth) was mixed with OM, then incubated for 3 months in glasshouse. The results after a 3-month incubation showed that SOM content did not statistically increase, but it improved based on the criteria, from very low to low level as OM was applied for ≥ 10 t/ha. It seemed that 10 t/ha Gliricidia sepium was the best dosage at this condition. There was a positive correlation between SOM content and aggregate stability index of Ultisols after fresh Gliricidia sepium addition.Keywords: Ultisols, soil aggregate stability, soil organic matter content

The research about potency of non-ionic organic compounds to decrease the dissolved iron (Fe) and to increase productivity of recently used ricefield had been conducted from August 2004 till January 2005. The objective was to study the effect of non-ionic organic compounds applied to control Fe and to increase rice production on recently used ricefield. The experiment used completely randomized design with four treatments and three replications. The treatments were consisted of four levels of non-ionic organic compounds (polysaccaride), those were 0, 75, 150, and 225 ppm. The result of this study showed that the effect of non ionic-organic compounds (polysacaride) at 225 ppm could reduce solubility of Fe2+ from 302,67 to 126,67 ppm for 30 days flooded. The yield of the rice (dry weight of grain and percentage filled out of grain) increased as much as 2,95 g dan 35 % with effect of polysaccaride at 225 ppm. Key words : non-ionic organic compounds, polysaccaride, recently used ricefield, flooded.

A field research about cultivating tithonia (Tithonia divesifolia) was aimed to determine the best row design and trimming period to produce high biomass and nutrient content of tithonia in Ultisol. The research was conducted in Andalas University Experiment Station and Laboratory of Research Center for Utilization of Nuclear Science and Technology (P3IN) Universitas Andalas Limau Manis Padang. The research consisted of 2 factors, row design for tithonia cultivation at farming site (R) (R1=alley fence, 1 m width times 5 m distance; R2 = 1 m width as a fence for farming site 10 m x 10 m area) as the main plot and trim period (U) (U1=trimming every 2 month, U2=trimming every 4 months), at 3 blocks The results showed that both row designs gave the same performance in terms of producing biomass and plant nutrients (N,P,K,Ca,Mg). The best trimming period was found under U1. Tithonia cultivation as R1 combined with trimming period (U1) yielded approximately 2.2 ton dry matter/ha, 62.82 kg N/ha; 17.67 kg P/ha; 81.06 kg K/ha 13.35 kg Ca/ha and 5.47kg Mg/ha. Both row designs with trimming period every 2 months could be recommended to cultivate tithonia in Ultisol.Key Words: Tithonia diversifolia cultivation, trim period, Ultisol
