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