Abstract
Soil plays a fundamental role in agriculture, environmental sustainability, and land development. Traditional soil identification methods rely on laboratory analysis and expert interpretation, which are often time-consuming, expensive, and inaccessible to small-scale farmers and local planners. This paper proposes the development and implementation of a Soil Identification Mobile Application (SIMA) designed to determine soil profiles in real-time and assist in land use planning decisions. The system integrates smartphone sensors, image processing, geolocation, and machine learning algorithms to classify soil types and recommend suitable land uses. The study evaluates the effectiveness, accuracy, and usability of the application compared to conventional soil analysis techniques. Results indicate that the mobile application achieves competitive accuracy levels while significantly reducing cost and response time. The findings highlight the potential of mobile-based soil identification systems to support precision agriculture, sustainable land management, and informed decision-making in both rural and urban environments.
Keywords—Soil identification, mobile application, land use planning, machine learning, geospatial analysis, agriculture.
I. Introduction
Soil is a critical natural resource that supports plant growth, regulates water, and contributes to ecosystem stability. Accurate identification of soil properties such as texture, structure, color, and moisture content is essential for determining its suitability for agriculture, construction, and environmental conservation. However, traditional soil analysis methods involve laboratory testing, field surveys, and expert interpretation, which may not be readily accessible, especially in developing regions.
The rapid advancement of mobile technology has opened new opportunities for integrating scientific tools into handheld devices. Smartphones equipped with cameras, GPS, and processing capabilities can serve as powerful tools for environmental monitoring. This paper explores the development of a Soil Identification Mobile Application (SIMA) that leverages these technologies to provide real-time soil classification and land use recommendations.
The objective of this research is to design, implement, and evaluate a mobile application capable of identifying soil profiles and assisting in land use planning. The proposed system aims to bridge the gap between scientific soil analysis and practical field application, particularly for farmers, land planners, and environmental managers.
II. Literature Review
A. Traditional Soil Identification Methods
Conventional soil identification involves field sampling followed by laboratory analysis to determine physical and chemical properties. These methods provide accurate results but are limited by high costs, time delays, and the need for specialized equipment and expertise.
B. Digital Soil Mapping
Digital soil mapping uses geographic information systems (GIS) and remote sensing data to predict soil properties across landscapes. While effective at large scales, these methods may lack precision at the local level and require extensive datasets.
C. Mobile Applications in Agriculture
Mobile applications have been widely adopted in agriculture for crop monitoring, weather forecasting, and pest management. Recent developments include apps that utilize image recognition and machine learning to identify plant diseases and soil conditions.
D. Machine Learning for Soil Classification
Machine learning algorithms such as convolutional neural networks (CNNs) and decision trees have been used to classify soil types based on images and sensor data. These approaches demonstrate high accuracy and adaptability, making them suitable for mobile implementation.
