Penentuan Bulk Density Ultisol Di Lahan Praktek Terbuka Universitas Labuhanbatu

Abstract

Bulk density is the weight of a given soil mass per unit volume. Soil volume is the volume of soil density including soil pores. Soil that is denser has a bulk density that is greater than that of the same soil but is less dense. In general, the topsoil on mineral soils has a lower bulk density value than the subsoil. The purpose of this study is Bulk density is to determine the density or Bulk density on open land in practice land because soil processing is often carried out by Labuhanbatu University students. Soil analysis is carried out in the integrated science laboratory of the Faculty of Science and Technology, Labuanbatu University. This research was conducted from January 2021 to April 2021. The results obtained showed that the bulk density value for the observed soil was 1.060 gram / cm3 so that the availability of organic matter also had an effect, this was because the more organic matter contained in the soil, the higher the density soil.
