Abstract

Evaluation Status of Organic Matter Content and Soil Physical Properties (Bulk Density, Texture and Soil Temperature) the Coffee Crop Land (Coffeea Sp.) in Some Districts Dairipurpose to makeevaluation status of the organic matter and soil physical properties (bulk density, texture and soil temperature) the coffee crop land (Coffeea Sp.) in some districts Dairi. Sampling using free methods tosurvey the level of review and analysis of data C- organic by Walkey and Black method, bulk densityby Ring Sample method, texture by Hydrometer method and soil temperature (oC) using the formula ofBraak, and interpret the nutrient status of the map through the program ArcMap 10. Parameters in the analysis are C-organik, bulk density, texture and soil temperature. The result of research showed thatthe nutrient status of the research area map C-organic consists of a very low criteria (3 sample), low(13 sample),being(12 sample) danhigh (10 sample). Bulk Density, porous criteria (13 sample) and solid (25 sample). Texture, very smoothcriteria (1 sample), smooth (6 sample), rather smooth (10 sample), being (9 sample), a bit rough (7 sample) dan rough (4 sample), andrezim Soil TemperatureIsohyperthermic (38 sample). Keywords :C-organic, bulk density, texture and soil temperature.

Abstract

This research was heldto know sprending of C-organic on paddy soil land at Village of Sei Bamban Subdistric of Sei Bamban Distric of Serdang Bedagai. This research was executed in Village of Sei Bamban Subdistric of Sei Bamban Distric of Serdang Bedagai on May until August 2015. Samples were taked with method Survey Free Grid of storey level semi detail survey. Parameter which was measured is C organic and analysed with Walkley and Black methods.The results of research were obtained four criteria C-organic nutrient status is very low, low, medium and high. At very low criteria have wide equal to 901,66 Ha. At low criteria have wide equal to 196,34 Ha. At medium have wide equal to 140,10 Ha. At high criteria have wide equal to 0,74 Ha.Keywords: Mapping, C organic, Paddy Soil, Village of Sei Bamban
