1. Soil Structural Gradients as Drivers of Multiyear Spectral Variability: A Robust Framework for Management Zone Delineation in Heterogeneous Sugarcane Systems Persistent soil structural gradients are widely recognized as key drivers of spatial heterogeneity in perennial cropping systems. In the heterogeneous sugarcane production environments of northwestern Argentina (Salta and Jujuy provinces), contrasting sandy and clay-rich sectors generate long-term differences in crop growth potential and resource-use efficiency. Distinguishing stable edaphic influences from transient seasonal variability is essential for reliable precision management. This study... H.J. Fernandez Download paper
2. Development and Field Validation of SMART-C: A Geostatistics and PCA-Based Decision Framework for Site-Specific Cocoa Management in the Brazilian Amazon Cocoa production plays a major socioeconomic role in Pará State, Brazil’s largest producing region, with annual output exceeding 140 thousand tons. Although Brazil ranks among the world’s leading cocoa producers, most production systems are still managed using field-average approaches that disregard within-field spatial variability of soil attributes and crop performance. This limitation restricts input efficiency and long-term system sustainability in perennial tropical systems.This...
