The Recent ricefield on marginal land such as Ultisol and Oxisol has low productivity due to Fe-toxicity for rice plant (Oryza sativa.L). Flooded ricefield has reduced Ferri (Fe3+) form into Ferro (Fe2+) from which is easy to dissolve and can be toxic for plant growth. This research was aimed to determine Fe concentration that causes toxic for rice growth on sand medium either under flooded or unflooded condition. Iron was applied in form of FeSO4 at 10 levels (0, 2, 4, 8, 16, 32, 64, 128, 256, 512 ppm). Based on laboratory analyses and visual symptoms, it was found that Fe toxicity was started at Fe concentration 128 ppm. Form of Fe which is toxic to this rice plant was ferro (Fe2+) because this form is active in plant metabolism. Fe concentration at 128 ppm both conditions had shown reddish brown spot on the whole plant, therefore growth and development of plants either above or below soil surface was limited or stressed. Keywords: recent ricefield, Fe toxicity, Ferro and Ferri, brownish symptom

The area at the foot of Mount Talang is one of the areas that excellent in agriculture, especially the cultivation of horticultural crops. In the northern area with steep slope conditions, the local community applies an intensive monoculture cropping system, this will accelerate land degradation in the long term. This study aims to examine the physicochemical properties of monoculture agricultural land in the northern foothills of Mount Talang on several slopes. This research was conducted with a survey method, soil sampling was carried out by means of purposive random sampling, on monoculture agricultural land on slopes > 45%, 25-45%, 15-25%, and 8-15% and forest as control, at a depth of 0 -20cm and 20-40cm. The results showed that the soil texture that dominates at the forest and monoculture agricultural land are dusty loam. Soil water content increases with increasing soil layer depth, soil water content in monocultures 25-45% (73.72%) is the highest. Soil volume weight ranging from 0.4-0.6 g / cm3 has the same tendency at both soil depths. The total pore space of forest land and monoculture agricultural land is a large average of 75% with high criteria. The highest soil organic C content was found in monoculture agricultural land with a slope of >45%. The pH value of H2O for all land uses was 5.15-5.29 and the pH for KCl was 4.5-5.2 for acid criteria. The cation exchange capacity was above 40 me/100g (very high criteria), the total N content was 0.8-1.6% with very high criteria, too. Based on the researchs data, the physicochemical properties of monoculture agricultural land on several slope classes matched the physiochemical conditions of the forest. The potential for land degradation is still minimal even though it is on the upper slopes of the foot of Mount Talang. However, monoculture farming while maintaining soil organic matter content must remain a priority for agricultural land management in this area.Key words: monoculture land, forest, slope, North area of foot Mount Talang

A reseach about determination land degradation on several plantation ecosystems in Dharmasraya Regency, West Sumatra. This research was aimed to study types of perennial crops (trees) which contributes to alleviate land degradation. The work was conducted in Sungai Rumbai Dystrict, Dharmasraya regency and in Soil Science Laboratory, Agriculture Faculty Andalas University. Soil samplings were taken at Ultisols having 0-8% slope (flate-undulating). Land use type being considered was original forest, oil palm, rubber, coffee, and cocoa plantation. Composite soil samples were taken for four replications on 1-20 cm depth. At each sampling site was accompanied by five drilling soils. Then, four undisturbed soil was also sampled at the same depth with disturbed soil samples for determining soil bulk density values. The data collected were analyzed statistically by using analyses of variance, and then continued by using Least Significant Difference (LSD) at 5% level. The result showed that rubber and cacao plantation contributed to better soil ecology value than oil palm and coffee land use. It could be proved from organic carbon (OC) and bulk density (BV) of the soils which were alsmost the same as those from forest land use. Key Words: Land degradation, plantation crops
