INTRODUCTION agricultural practices. The consequences of soil Soil compaction is a critical soil health issue that compaction extend beyond reduced crop yields to affects agricultural productivity, ecosystem include increased susceptibility to erosion, functions, and environmental sustainability. In decreased soil biodiversity, and impaired nutrient Bintulu, Sarawak, a region characterized by diverse cycling. land uses including agriculture, residential areas, industrial zones, and natural ecosystems, In Bintulu, where agriculture plays a significant understanding the implications of soil compaction role in the economy and natural ecosystems on soil fertility is essential for sustainable land support biodiversity and ecological services, the management and agricultural practices. impact of soil compaction on soil fertility warrants careful examination. Different land uses in Bintulu Soil compaction occurs when soil particles are may experience varying degrees of soil compaction compressed, reducing pore space and limiting due to differences in land management practices, water infiltration, root penetration, and air soil types, and human activities. circulation. This phenomenon is often exacerbated by human activities such as heavy machinery This study aims to assess soil compaction and its operation, urban development, and intensive implications for soil fertility across diverse land https://www.theamericanjournals.com/index.php/tajas 1 THE USA JOURNALS THE AMERICAN JOURNAL OF APPLIED SCIENCES (ISSN – 2689-0992) VOLUME 06 ISSUE03 uses in Bintulu, Sarawak. By examining soil various land use types, including agricultural, compaction levels and fertility parameters in residential, industrial, and natural areas. These agricultural, residential, industrial, and natural surveys informed the selection of sampling areas, we seek to elucidate the relationships locations, taking into account factors such as land between soil compaction, soil fertility, and land use management practices, soil characteristics, and practices. vegetation cover. Through field surveys, soil sampling, and Following site selection, soil sampling was carried laboratory analyses, we will quantify soil out using a systematic grid pattern to capture compaction levels using penetrometer readings spatial variability within each land use type. Soil and assess soil fertility parameters such as organic samples were collected at multiple depths using matter content, nutrient levels, pH, and microbial soil augers or coring devices to assess soil activity. By comparing soil characteristics across compaction and fertility parameters at different different land uses, we aim to identify patterns, soil horizons. Careful attention was paid to avoid trends, and potential drivers of soil compaction and sampling from areas with evident disturbances or fertility variations. variations in soil properties, ensuring the integrity and representativeness of the collected soil The findings of this study are expected to provide samples. valuable insights into the impact of land use practices on soil health and productivity in Bintulu, Soil compaction levels were assessed using Sarawak. Understanding the relationships between penetrometer readings taken at each sampling soil compaction, soil fertility, and land use is crucial point to quantify soil resistance to penetration. for implementing effective soil management These measurements were conducted strategies, promoting sustainable agricultural systematically along transects to capture spatial practices, and conserving natural ecosystems in the variations in soil compaction within each land use region. type. Concurrently, soil samples were transported to the laboratory for comprehensive soil fertility By elucidating the linkages between soil analysis, including assessments of organic matter compaction and soil fertility across diverse land content, pH, nutrient levels, cation exchange uses, this study contributes to the development of capacity (CEC), and microbial activity. informed land management policies and practices aimed at enhancing soil health, preserving In the laboratory, standard analytical methods ecosystem integrity, and fostering sustainable were employed to determine soil fertility development in Bintulu, Sarawak. parameters, ensuring consistency and accuracy in the assessment process. Soil samples underwent meticulous processing and analysis using METHOD established techniques such as colorimetry, The process of assessing soil compaction and its spectrophotometry, and titration methods. Quality implications for soil fertility across diverse land assurance and quality control measures were uses in Bintulu, Sarawak, involved a systematic and implemented to validate analytical results and multifaceted approach. Initially, comprehensive minimize potential sources of error, including field surveys were conducted across the study area calibration checks, duplicate samples, and to identify representative site
