1. Use of Profitability Maps in Precision Agriculture As a Strategic Tool for Decision-makingBrazilian agribusiness plays a significant role in the national economy, accounting for approximately 27% of the Gross Domestic Product, while operating in an environment characterized by substantial exposure to climatic, operational, and market risks. In commodity-based production systems, where farmers act as price takers, economic efficiency fundamentally depends on effective cost and revenue management, as well as the proper allocation of productive resources. In this context, this study ... W. Nart Macedo, L. Gebler |
2. Economic and Ecological Performance and Farm-level Adoption of Market-available Tools for Variable-rate Nitrogen Management in a Region of Small-to-medium-scale AgricultureThe proposed contribution combines the results of extensive multi-year field trials on variable rate-nitrogen fertilization (VRN) of winter wheat with the results of a series of farmer surveys, and findings drawn from a government investment subsidy program. All three data sources (field trials, surveys, investment subsidy program) cover roughly the same period and agricultural area. The field trials were conducted from 2023 to 2025, the surveys in 2020, 2022, and 2025, and data on the invest... M. Gandorfer, B. Vinzent, J. Pfrombeck, J. Garnitz, F. Maidl |
3. Farm-level Economic Viability Site-specific Weed Management (SSWM)Background: Site-specific weed management (SSWM) is promoted as a strategy to reduce herbicide inputs without compromising crop yield. Despite rapid advances in offline and online AI-based weed mapping, the farm-level economic viability of SSWM under real-world weed patchiness and imperfect detection remains uncertain. Methods: A grid-based (1x1m, 50x50cm and 25x25cm) economic decision model for SSWM was developed and evaluated using 31 empirical weed... M. Gandorfer, J. Pfrombeck, V. Pitsyk, D. Pannell |
