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

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.

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

Phosphorous (P) is one of plant nutrient needed by plant in much amount as it is called as macro essential plant nutrient. This element, P, has complete problems. It is not only found in a small amount in soil compared to other nutrients, but it also has some problems in soil if it is there. At acid soils such as Ultisols, phosphorous is binded by aluminium (Al) and iron (Fe), while in basic soils it is held by calcium (ca) and magnesium (Mg). Therefore, both in acid soils or basic soils P is not available for plant growth. A research about P-fertilizer use efficiency for chilli (Capsicum annum) on intensification land which was added organic matter (OM) using P-32 technique was conducted in glasshouse and soil laboratory of Agricultural Faculty, and in laboratory of center for research utilizing nuclear science and technique (P3IN) Andalas University Limau Manis Padang from 1996 to 1997. The objective of this research was to measure P-fertilizer use efficiency (FUE) by chili on horticulture intensification area (on Andisols) as affected by organic matter. This research was designed as completely randomized design (CRD) with 2 factors those were TSP (consisting of 0, 25, and 50 kg P2O5/ha) and OM especially chicken manure (consisting of 2, 4, 6, 8, and 10 ton/ha) by 3 replications. The results showed that plant dry matter became higher by decreasing P-fertilizer added but was not significantly affected by manure. P-fertilizer (P-32) uptake by plants was not significantly affected by P-fertilizer and manure aapplication, therefore P-FUE decreased by increasing P-fertilizer added and tended to increase by increasing dosage of manure applied. Key words: fixed-P, available-P, desorpted-P, FUE, P-32 technique

Land use change from agricultural land into non-agricultural land such as for industries, streets, and others has increased erosion impact, nutrient and sediment in a watershed. That process had caused land degradation in a watershed, therefore, land productivity will decrease and even will cause flood during rainy season and drought during dry season. In order to find out what will happen if land use change takes part, a software using BASIC language was arranged. This software is aimed to simulate erosion process easier. This software uses USLE and Snyder in predicting erosion. Additionally, this software is also able to predict sediment delivery.Keywords : Software conservation, language BASIC.

Intensive deforestration for the purpose of agricultural field and transmigration area has happened lately in Dharmasraya Regency, West Sumatra. Land use change from forest into dry land farming, mixed trees and oil palm plantation, as well as rubber plantation has caused different level of soil fertility as a consequence of ecology changes of the areas. The objectives of this research were to identify the change of soil organic matter content, plant nutrition level, as well as bulk density of the soils at each land use. This research was conducted in Sungai Rumbai, Dharmasraya Regency in 2007. Soil samples were taken from 5 land use, those were dryland farming, mixed trees, oil palm plantation, rubber plantation, and natural forest. The soil samples, then, were analysed for the soil organic matter content (%), N-, P-, and K-content, as well as bulk density (BV) in soil laboratory, Agricultural Faculty, Andalas University Padang. The result showed that land use change from forest ecosystem into other ecosystems had decreased soil fertility level. This was reflected by the decreasing soil organic matter content, increasing soil bulk density. Nutrient status of the soil also decreased, especially potassium (K) level. Compared to the forest ecosystem, soil organic matter decreased by 13, 26, 33, and 36% respectively for dry land farming, mixed trees and oil palm plantation, as well as rubber plantation. Soil bulk density of the land use which was still close to soil under forest ecosystem (0.83 gcm-3) was found in rubber plantation (1.00 gcm-3), then followed by mixed trees (1.11 gcm-3). Potassium level of the land uses which were close to forest ecosystem (0.44 me/100g) was in rubber plantation (0,33 me/100 g), as well as in oil palm plantation(0,34 me/100 g). Based on the results above, it can be concluded that rubber and oil palm plantation was types of land use having better soil ecology compared to the other land use.

Rhizobacteria from various research results have shown an important role in producing organic compounds (phytohormone) which can affect plant physiological processes even in low concentrations. This research aimed to study the production of Indole Acetic Acid (IAA) in several plants rhizosphere, to calculate the rhizobacteria population that able to produce and synthesize IAA and to isolate these rhizobacteria from several rhizospheres of cultivated plants (maize and peanut) and bush plant i.e. karamunting (Rhodomyrtus tomentosa) and titonia (Tithonia diversifolia). All plants and crops were obtained from experimental station Faculty of Agriculture Andalas University. Further research is conducted in Soil Biology Laboratory Faculty of Agriculture. Experimental design in this study was not used but the data obtained from 3 replications tested by T test at 5% level and if it was significantly different it would be followed by further HSD tests at 5% level. Highest content of IAA was found in the peanut crop (67.30 ppm), followed by maize (53.61 ppm) and 28.53 ppm for titonia. Whereas the lowest content of IAA was found in karamunting rhizosphere, it was 22.29 ppm. The highest amount of rhizobacteria was obtained from peanut rhizosphere followed by maize and titonia i.e 18.28, 12.08 and 7.87% of the total population, respectively. There was no IAA producing rhizobacteria population was found in karamunting rhizosphere. Based on the results of the ability of the test to produce IAA in the King’s B liquid medium at low pH (pH 4.0), the leading isolates were obtained in each rhizosphere, namely: J.2b and J.3b isolates from maize rhizosphere; Kc.1b, Kc.2b and Kc.3b from peanut isolates, and Ti.3c isolates from titonia rhizosphere.Key words : Rhizobacteria, IAA, Rhodomyrtus tomentosa, Tithonia diversifolia, peanut and maize

Last researchers reported that Tithonia diversifolia (Mexican sunflower) could replace 25% to 50% of N and K of commercial fertilizer applied in chili production on the first and second planting time in the Ultisols of West Sumatra. A Continuation field experiments was conducted to find out the the appropriate NK cobination sources should be added on the third season to get the higest yield of maize. The treatments were the combination of NK T. diversifolia + NK commercial fertilizer which is maize needed. There were 9 treatmens such as A(0%+0%); B(0%+0%); C(50%+25%); D (50%+25%); E(25%+75%); F(25%+75%); G(50%%+50%); H(50%%+50%); and Control (0+100%). The results showed that integrated use 50% NK from tithonia with 25% NK from commercial fertilizer is the appropriate NK combination to get the higest yield (5ton ha-1)of maize on the third season in Ultisols, if on the first season for chili planting time have reseived as 50% + 50% and on the second season for chili planting as much 25%+75% NK from titonia and NK from commercial fertilizerKey Words : Ultisols, tithonia, corn
