Groundwater pollution due to chemcal application in agriculture activities has caused much public concerns. Based on the researches having been conducted, it was resulted that chemical leaching in soil frequently showed spatial pattern. Based on the fact, a field research was conducted in Maury silt loam soil (fine, mesic, mixed, Typic Paleudalf) to evaluate spatial variety of Sr movement into and below rooting zone. Chemical material SrCl2.6H2O was evenly distributed on soil surfacein a 18 x18 m plot. Soil samples were taken 4 times (after receiving rainfall 166, 3, 586, and 1085 mm) in 54 locations within the plot. At each sampling undisturbed soil was taken from surface until 100 cm depth, then the Sr element was analyzed from each 10 cm depth. The results showed that there was no spatial pattern found for Sr movement within a 100-cm soil depth in each sampling date. Therefore, based on the analysis of variance, it was about 95% of Sr2+ found on 0-20 cm soil depth even though after receiving 1085 mm rainfall. Key Words: groundwater pollution, agricultural chemicals, spatial structure

The research was aimed to determine land suitability for manggis (Garcinia mangostana L) as a type of conservative crops in seven regions in District of Lima Puluh Kota. Survey method with purposive random sampling was employed at this study. Soil samples were randomly taken in each region for the physical and chemical analyses in laboratory. Secondary data for climate were obtained at Agriculture Department of the District. Both soil and climate data were arranged and interpreted for manggis growth requirement. The result showed that actual land suitability for each region was classified into S2-S3, with limiting factors were availability of plant nutrients and water, as well as topography. However, by improving soil fertility through OM application as well as soil conservation action, potential land suitability could be increased to be S2-S1 as in Guguk and Bukit Barisan.Keywords: land suitability, soil conservation, manggis

The addition of the organic matter into a soil will improve the physical, chemical and biological properties of the soil and the soil quality can be maintained. The organic matter application into agriculture field can be done directly at no tillage system farming or can be composted insitu. In the no tillage system weeds were controlled by herbicide. Application and insitu composting of the crop residual and weed were incorporated into the soil before maize planting. The results of the experiment showed that, the direct (insitu) composting system gave the higher yield of maize and more profitable than without application of organic matter. The utilization of organic matter in no tillage system and insitu composting were more advantageous because the organic matter were not processed such as compost, and cost as well as time was more efficient.

This research was aimed to study alternative techniques for soil conservation in controlling erosion and nutirients lost from Andisol planted with potatoes in upper part of Merao watershed, in Kerinci Region, Jambi Province. The research was conducted in Kebun Baru, Kayu Aro, Kerinci. The soil and sediment samples were analysed at Soil and Land Resource Laboratory, Agriculture Faculty, Institute Pertanian Bogor. Erosion was measured on small plots consisting of seven (7) treatments and three (3) replications considered as blocks. The results showed that planting potatoes across the slope direction, or making soil bed across 15% slope, or soil bed as slope direction and across slope direction every 4.5 m distance could control erosion and nutrients lost, and did not affect potato yield compared to soil bed as slope direction. Planting potatoes on soil bed as slope and across slope direction in each 4,5 m distance (modified farmers model) reduced erosion, soil organic-C, and total-N lost for 65.89, 65.19, and 24.55%, respectively, compared to planting as slope direction. Keywords: erosion, nutrient lost, sedimentation

Chemical leaching from soil surface will cause groundwater pollution. Researches showed spatial correlation of the leaching chemicals. Based on the fact, a filed research was conducted at Maury silt loam soil (fine, mesic, mixed, Typic Paleudalf) to evaluate spatial variations of anion movement, in tis case was Cl, into and below rooting zone. Source of chloride, SrCl2.6H2O, was evenly distributed on soil surface within a 18 x 18 m2 plot in University of Kentucky Experimental Station, Lexington, Kentucky USA. Soil was sampled for 4 times (after receiving 166, 310, 586, 1085 mm rainfall), in every 10 cm depth for 54 points within the plot. The result showed that Cl- movement did not show spatial model from soil surface into 100 cm profile in every sampling date. Therefore, based on analysis of variance, Cl- concentration was significantly different from one depth to another within one sampling time. Cl- concentration found on the depth of 100 cm was 75, 58, 27, and 15% for sampling time I, II, III, and IV, consecutively.

A research about relationship between soil properties and crop yield was conducted in Pandai Sikek, Tanah Datar Region, center for cabbage and carrot production, West Sumatra in 2004 and 2005. Soil samples were collected from rainfed paddy soils by purposive random sampling. Soil samples were analyzed in Soil Laboratory, Agriculture Faculty and Agriculture Polytechnique Laboratory, Andalas University. Several soil physical properties analysed were soil bulk density and total soil pores by using gravimetric method, permeability with de Boodt method, soil water content at several pF values using pressure plate apparatus, and soil strength by using penetrometer. Soil chemical parameters analysed were soil pH using pH-meter, organic-C using Walkley and Black, available P using Bray II, and cation exchange capacity using NH4-leaching at pH 7.0, and N-total using Kjehdhal method. Crop productions were sampled from a 3x3 m2 of soil sampling area. The result showed that soils planted by cabbage and carrot had good soil physical properties, such as having balanced pore size distribution. The chemical properties of the soils were good as well, except N, K- and Ca-exchangeable which were very low. The other soil properties were quite good. Soil physical properties gave different response on both crops. Carrots were more response aeration pore and soil organic matter content, then cabbage was more response on BV, TSP, and slow drainage pores. While soil chemical properties did not give significant response. Both crops responded on Ca, but cabbage was more response on N-total, and carrot on CEC and saturated cationKey Words: Soil Physical Properties, Soil Fertility, Crop Productivity

Research on soils fertility of rice soils has been done on three catchment in West Sumatra province ie; Ulu Selo ( inland areas of selo river) at Tanah Datar district conducted three Kenagarian ( traditional village) Simpurut, Gurun, and Padang Laweh. Lembang catcment at Solok district is conducted ubo irrigation scheme ubo which divided as Ubo atas irrigation scheme and Sirukam. Sumpur cathment at East Pasaman District conducted three Kenagarian, Lundar, Petok and Kuamang. All of irrigation scheme located at agroclimatic zone C1 up to D2, with charaterize 2 or 3 consecutive wet month and 3 or 4 consecutive dry month. Soils were developed from volcanic parents materials. Rice soils of Ulu Selo shown lower pH value compared to the soils with land use is mixed garden, which some of the sampling point has shown the pH lower than 4. the rice soils of Lembang and Sumpur also shown the similar trend of pH but the value not so extremely like the soils from Ulu Selo. Related to the minimum value of carbon in rice soils is indicate that some of the rice soils in the research areas could be grouping as degraded land. The rice soils from Sumpur has high natural soil fertility which which shown on the natural reserved of nitrogen, phosphor and potassium. The soils condition could support the rice production up to 8t/ha/ GS without additional nutrient. While soils from Ulu Selo shown lower content of phosphor. Based on this research author suggested to fertilizer program is better done based on the condition of soils itself. Even the natural soils fertility is high is not reccomended to use addtional artificials fertilizer.Key words: cathment studies, natural soil fertility, rice production and land degradation.
