Forensic soil science and forensic botany have experienced a significant rise in interest and recognition in recent times. In forensic soil science, molecular biology, chemistry, geophysics, mineralogy, and soil morphology are applied to legal issues. Forensic botany examines plant anatomy, behavioural characteristics, growth patterns, reproductive cycles, and categorization systems for judicial purposes. Acceptance of botanical evidence in legal systems requires adherence to specific requirements. Taking into account their potential as crucial court evidence, this review highlights the importance of forensic soil science and botanical analysis in criminal investigations. Several scientific fields are discussed, including soil morphology, chemistry, geophysics, and plant anatomy. While countries such as New Zealand and the United Kingdom have proven the effectiveness of these techniques, they are underutilised globally. Case studies highlight the importance of pollen analysis and soil evidence in determining geolocation, identifying drug manufacturing sites, and connecting suspects to crime scenes. To encourage their integration into international forensic practices, the necessity of more knowledge and training in these areas is stressed.
