Mapping Land Used After Bricks Mining Area at Potorono Village Banguntapan Yogyakarta

摘要

The degradation on the soil after bricks mining was limited land used to agriculture plant in fields. The out put this research to know land used after mining in the various depths after bricks mining. The mapping was land used after bricks mining in the six villages mining at Potorono Banguntapan District of Yogyakarta in the 2016. The method of this research was used survey techniques and over lapping map land use. Mapping base was used satellite imagery map to determine the boundaries of operations, and then use the map was used various soil deeper in mining. The map of the plant is determining on the land use after the land was reclamation lands. The result of this research is mapping irrigated lands, settlements, gardens, and field moor at several debts after bricks mining. The pasca bricks mining will be restrict land use of agricultural. At mining on the depth about 100 cm was grown by paddy soil in land, while the mining of more than 200 cm, the wetland is unsuitable by paddy soil. The limited alternative of agriculture plants was determined by the level of decline fertility and organic matter in soil, add bulk density and sand content in the soil. In the former bricks mining can be planted with paddy soil is an area with good irrigation requirements with a production under 7 tones per hectare. While in the mining above 200 cm and nothing irrigation, the farmers will be grown crops with irrigation depends on the rain. The conclusion on the research is content of organic matter in the mining was important by nutrient storage soil. The amelioration to marginal soil was soil structure repaired by organic matter for water and nutrient storage. The nutrient was sufficient to determine on reclamation to growth of plants after the mining for sustainability agriculture. On the brick mining was allowed soil take at top soils, after mining it must be done as soon as possible for reclamation land towards sustainability agriculture.
