Evaluasi Kemampuan Lahan di Desa Sungai Jelayan Kecamatan Kedawangan Kabupaten Ketapang

Sungai Jelayan Village is one of the villages in Kendawangan District, Ketapang Regency, which still has the potential for sustainable management. Evaluation of land capability is one of the efforts to overcome the reduction of land degradation. Land capability is an assessment of land units for particular uses, assessed from each inhibiting factor. This study aimed to determine the characteristics of the land according to the land capability parameter, assessed the land capability sub-class, and provided suggestions for land use based on the land capability sub-class in Sungai Jelayan Village. The research stages started from preparation, preliminary survey, determination of research location based on land units consisting of soil type, slope class, land use and there were 9 land units, and determination of observation points, as well as field observations and soil sampling, laboratory analysis, data processing and presentation of results. The results obtained 2 soil orders, namely Entisols and Inceptisols. The results of the land capability evaluation were divided into five land capability classes and sub-classes, namely class II-s, III-s, IV-w, V-w, and VIII-es. Improvement efforts or efforts to use land sustainably could be carried out in 5 ways, namely intensive cultivation, moderate cultivation, limited cultivation, nature reserves/protected forests, and intensive grazing.

Land capability evaluation and classification of Obosi Land in Anambra State Nigeria

Land capability evaluation and classification of Obosi land was carried out on an approximately total area of 25.58km2 using the map of the area. The aims of the study were to map out the soils of Obosi, classify them for suitability and sustainability for agricultural production and other land use development projects. Auger sample and profile pit samples were collected and examined. Using morphology and topography of the surveyed area, three mapping units; MUI-lowland areas, MUII- upland areas and MUIII-gullied areas were established. The result of the study indicated the textural class of the soils to be sandy loam, except for upland areas in Auger 1 were the textural class were loamy sand. The particle sizes range from 50gkg-1-90gkg-1 clay, 50-90gkg-1 silt, 130-590gkg-1 fine sand and 310-650gkg-1 sand. The pH of the soils varies from slightly acidity to slightly alkaline and was fairly uniform throughout the depths. The exchangeable bases, CEC, TEA, SAR and ESP of the soils were found to be low and below their critical level for crop production the base saturation value of the soils range from 22.28-99.21%. The low land areas and the upland areas were found to be suitable for arable crops. They fall under the suitability class S2 (suitable) and the capability class 11. Their major constraint on agricultural production is low fertility status. The gullied areas MUIII were found within the uplands and low-land areas. They fall under the non-suitability class NS (not suitable) and the capability class vi. The prominent limitation of this unit is erosion hazard. The area cannot be used in their present state without serious reclamation activities. The soils were classified as mixed isothermic kandic argiudult using the USDA soil Taxonomy and correlated as eutric ferralsols by FAO-WAB classification. Generally the soils need to be upgraded in soil nutrients through soil organic matter application and reclamation processes to produce maximally.

LAND CAPABILITY EVALUATION FOR THE EFFECTIVE LAND USE AND SOIL PROTECTION MEASURES IN DOBRICH REGION

An assessment of the suitability of the arable land in the Dobrich region for its effective agricultural use has been prepared using an eight rate classification where the land valuation strategy guarantees the conservation of natural resources, with particular attention to erosion as a limiting factor. Maps of the area with Land Capability evaluation classes for effective agricultural and erosion control land use and the actual risk of water erosion have been developed.This allows the use of an integrated approach to the definition of soil protection measures - taking into account both soil constraints (labeled with subclass land) and the need for prevention against erosion processes. A set of different soil protection practices is recommended, each determined according to the specific soil, topographical and climatic features of the studied area, determined by the class and subclass of the land and depending on the degree of erosion risk and the way of land use (defined by Physical Blocks, 2016). The agronomic assessments according to the soil and climate conditions of the main agricultural crops are lnked to the detailed large-scale database created in the GIS format and the most suitable places for their cultivation on the territory of the Dobrich region have been identified. The agronomic fitness of arable land for the cultivation of wheat, maize, peaches and vines is assessed. Maps for the degree of their agronomic fitness were prepared. It is clear that almost all of the entire territory has a very good and good land for cultivation of these crops.

Evaluasi Kemampuan Lahan Dan Arahan Pemanfaatan Lahan Di Daerah Aliran Sungai Wai Tina Kabupaten Buru Selatan Provinsi Maluku

Tina Wai watershed area 48,132 ha, located in the South Buru and serves as a provider of water for the local community. Land Capability Evaluation and Tina Wai Watershed Land Use in South Buru, Maluku Province, has been performed in order to determine the land capability classification level, and determine the direction and pattern of land use in accordance with their respective land capability class. The research method is a survey method with a pattern of synthetic and analytical approach with a flexible range of observation following the change in shape of physiographic and land use. The results found that Tina has 6 Wai watershed land capability class, ie class III, IV, V, VI, VII, and VIII with factor inhibiting dominated by undulating slopes to very steep, erosion rates to very heavy weight, medium texture soil, permeability rather fast to slow, moderate sensitivity to erosion, rock gravel of moderate-to-many, and the threat of flooding rather frequently. Land capability class has the most extensive is the fourth grade with an area of 24.636 ha, or 51.19%. Referrals for agricultural land use is 29,184.75 ha or 61.89; for plantations, livestock and forest production by 8396.75 ha or 17.38%; for the protected forest of 6,941.25 ha or 14.42%; and for the nature reserves of 3036.00 ha or 6.31%.
