Abstract

This study aims to identify land characteristics (soil physical characteristics and soil chemistry). Identifying land characteristics for dragon fruit plants (Hylocerreus undatus) and explaining land characteristics based on soil and plant observation parameters.This research was conducted in Purun Besar Village, Segedong District, Mempawah Regency. Then followed by conducting soil analysis at Soil Chemistry and Soil Fertility Laboratory, Soil Physics and Soil Conservation Faculty of Agriculture, Tanjungpura University Pontianak. The research method starts from preparation, field survey, soil analysis in the laboratory, data interpretation, and presentation of results. The parameters observed in this study are divided into 2 parts: field observation and laboratory analysis. Parameters in the field are groundwater depth (cm), rooting medium, soil maturity, soil structure, sulfidic depth, surface rock and rock outcrop.  The parameters in the laboratory are C-Organic (%), Cation Exchange Capacity (cmol (+) kg-1), N-Total (%), P content available (ppm), K-dd content (cmol (+) kg-1 ), soil reaction (pH), Al saturation, salinity, soil texture, plant height, number of branches in stem and data processing and potential land analysis. Keywords: Land Characteristics.

Abstract

This study aims to determine the chemical characteristics of peat soil in various depths of water drainage. This research was conducted in Rasau Jaya General Village Rasau Jaya Sub-district, Kubu Raya Regency. Soil analysis was conducted at Soil Chemistry and Soil Fertility Faculty of Agriculture, University of Tanjungpura Pontianak. Soil sampling is done by disturbed soil sampling method and done by diagonal. Soil sampling was conducted on 3 plot of land observation, consisting of P0 without drainage channel, P1 drainage water channel depth 30 cm and P2 water depth of drainage channel 60 cm. Each plot is 40 x 50 m in size and there are 5 observation points. Each observation point there are 2 depths of 0-20 cm and 20 - 40 cm. The method used is descriptive data analysis to see comparison of chemical characteristics of peat soil in each plot of land P0, P1, and P2 which contained some water depth of drainage channel. The parameters observed in this study were soil reaction (soil pH), cation exchange capacity (CEC), base saturation (KB), N-total (%), P available (ppm), K (cmol (+) 〖kg〗 ^ (-1)), Ca (%), Mg (%), C-Organic (%). Keywords: Chemical Characteristics, Peat, Drainage.
