Technology Advancements and the Needs of Farmers: Mapping Gaps and Opportunities in Row Crop Farming
Abstract
1. Introduction
2. Overview of Row Crop Farming
3. Methodology
3.1. Literature and Survey Review
- For technological studies: focus specifically on robotic technologies with demonstrated applicability to row crop systems. This encompassed advances in sensor integration (e.g., multi-spectral imaging, LiDAR), AI and machine learning algorithms for decision support and automation, autonomous navigation strategies suitable for field environments, and robotic hardware optimized for energy efficiency, adaptability, and robustness in outdoor field conditions. Studies were also selected based on evidence of field deployment, operational efficiency, and sustainability benefits.
- For surveys and case studies: studies targeting row crop farmers or mixed-farm contexts, providing quantitative or qualitative data on barriers, motivations for adoption, or performance feedback, and presenting a clear methodology (sample size, geographic scope, and question framing).
- Exclusion criteria included conceptual-only research, greenhouse-specific technologies, studies focused solely on livestock, or surveys with unclear methodology or small sample sizes.
3.2. Commercial Product Identification and Filtering
- Proven applicability to row crop farming operations (e.g., seeding, weeding, spraying, monitoring).
- Autonomous or semi-autonomous capability.
- Field deployment or commercial availability (not just concepts or prototypes).
- Availability of technical data on sensors, capabilities, and operational features.
