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...
