1. Site-specific Nutrient Management in Citrus: Agronomic, Economic and Energy Implications of Variable Rate FertilizationBrazilian citrus production faces increasing challenges due to rising costs, intensifying climatic and biotic stresses, and the growing demand for optimization in input use, particularly fertilizers. In this context, precision agriculture can provide the conceptual and operational basis for site-specific management, allowing fertilizer application to be adjusted to the spatiotemporal variability of the production system. This study evaluated, under commercial-scale conditions, the effects of variable-rate... G.V. Bedum, A. Colaço, M. Gelain, R. Canal Filho, J.P. Molin, E. Otavio Da Silva |
2. Simulation of Different Nitrogen Fertilization Strategies Using Management Zones in Sugarcane CultivationNitrogen plays a central role in sugarcane physiology, as it is a structural component of amino acids, proteins, nucleic acids, and chlorophyll, being essential for photosynthetic activity, leaf expansion, biomass accumulation, and stalk formation. Given its relevance, nitrogen management efficiency represents a central research topic in sugarcane, particularly in systems characterized by strong spatial heterogeneity, where soil physical–hydric attributes, fertility levels, and environmental...

3. On-farm Precision Experimentation in Western Canada: A Case Study Focused on Adoption, Challenges, and Practical ResultsOn-farm experimentation can improve management practices by providing localized results that align with the environment, genetics, and management of a specific field, farm, or region. However, operational challenges, such as the time required to implement and harvest an experiment and analyze results, can be barriers to adoption. The technology available in modern machinery (e.g., variable-rate technology and yield monitors) can overcome operational challenges by autonomously implementing and... F. Hoffmann Silva Karp, B.
