The Beryllium-7, 7Be depth penetration in two seasons study at Timah Tasoh, Perlis

Abstract

This paper examines the 7Be penetration onto the soil surface within two seasons of different agricultural activity areas. This study was conducted during the wet and dry seasons in October 2015 until March 2016.Timah Tasoh is a catchment area located in Perlis State, Northern Peninsular of Malaysia and has been identified as the most suitable study site due to a small size of the catchment area. A total of sixteen core soil samples were taken over the course of the study using corer made of metal with a depth of 4cm each. All the results from this study site indicate that the 7Be penetration decreases exponentially decay in soil depth.The distribution of soil depth profile onto the soil surface or ho values for both seasons varied from 2.98 to 4.98 kgm-2 and from 3.57 to 5.57 kgm-2, respectively.Therefore, all the ho values of two seasons from this study are slightly higher from the results that have been reported by others. However, more extensive studies such as the addition of research areas should be carried out to obtain analytical data that can be used as future comparative data. ? 2022
