Influence of brick processing on changes in soil physico-chemical properties of Bhaktapur District, Nepal


Author(s): Shree Prasad Vista and Bibechana Gautam

Abstract: In the name of Urbanization and Industrialization, numbers of brick kilns are increasing day by day with the abundant manufacture of brick utilizing top fertile soil from the nearby agricultural land. So, this study was conducted to investigate the effect of brick industries on agricultural productive land in Bhaktapur district. The research was conducted in ten different brick factories of Bhaktapur district starting during 2018. The purpose of the study is to know the amount of nutrient dumped by brick factory and nutrient stored in the brick. With the objective of soil fertility assessment of nearby degraded land of brick factory this study was carried out. For this, purposive sampling method was followed by selecting four treatment from ten different locations of Bhaktapur district i.e. raw brick, furnished brick, soil within the premises of industry and soil from nearby agricultural land. Soil samples were collected and analyzed for total nitrogen, available phosphorus, available potassium, pH and organic matter content following standard procedure. The data obtained were subjected to statistical analysis using GenStat software. The result showed that there is significant decrease in total nitrogen, available phosphorus, available potassium and organic matter content of the soil from agricultural land to excavated land and from raw brick to brunt brick. Highest amount of soil nutrients (total N, available phosphorus and available potassium) and organic matter content were found on agricultural land but in lower range whereas, lowest is present in burnt bricks. Soil from agricultural land was found to be more acidic (<5 pH) in comparison to excavated land. Similarly, slight decrease in pH was noticed after burning of the brick. It was observed that about 45% of Nitrogen is stocked in finally prepared brick while 83% of nitrogen is lost from excavated land to furnace brick. Similarly, 52.8 % and 67.8% of phosphorus and potassium is stocked in furnace brick with the loss of 69.13% and 81.66% of them respectively from excavated land to burnt brick whereas, 46.60% of organic matter is dumped in brick with loss of 59.70% from excavated land.
