Resumen: La ganadería es clave en la dinámica social, territorial y económica del Uruguay. El riego incluido en estos sistemas tiene la capacidad de potenciarlos, si bien la adopción de esta tecnología en el rubro es limitada. Esta investigación pretende estudiar la dinámica del cambio técnico en el riego, focalizando en aquellos productores ganaderos que han adoptado esta tecnología, así como indagar los factores que llevaron a su adopción. El estudio se realizó utilizando tres abordajes: revisión de fuentes secundarias, entrevistas a ganaderos regantes y entrevistas a informantes calificados. Los ganaderos
regantes fueron categorizados como «innovadores», y las razones que llevaron a los ganaderos a adoptar el riego son el aumento de la productividad y la estabilidad productiva de los sistemas. Si se asume que la falta de conocimiento para aplicar el riego no es limitante y que no es necesaria una escala mínima para su aplicación, estos son dos factores favorables para una eventual estrategia de promoción de esta tecnología. Mejoras en factores como las políticas públicas (marco jurídico), capacitaciones a todos los actores involucrados y el empleo de predios demostrativos (enfoque predios foco) son algunas sugerencias que se plantean para dinamizar el cambio técnico en la situación actual // Summary: Livestock farming is key to Uruguay?s social, territorial and economic dynamics. Should irrigation be included in these production systems, it would have the ability to boost them, but for the time being, the adoption of this technology is still limited. This research aimed at studying the dynamics of irrigation, focusing on livestock farmers that have adopted this technology, and at investigating the factors that led them to its adoption. Three approaches were utilized: secondary sources revision, interviews to farmers who irrigate, and interviews with qualified informants. These farmers were typified as «innovators» and
the reasons that led them to adopt irrigation were the increase in production and the stability of their production systems as a whole. Assuming that there are no knowledge constraints to use irrigation, and also that a minimum scale is not necessary, these two factors may turn an eventual adoption policy very promising. Improvements in factors such as public policies, training policies addressed to all involved actors and the use of demonstration farms are some suggestions proposed to boost the technical change in the current situation.

ABSTRACT.- Advances in technology and analytics to support data-driven agriculture has important implications for global food security and environmental sustainability. However, relatively few studies have investigated the potential to leverage the power of on-farm data for improved agronomy at scale using geospatial machine learning methods. Working in high-yielding rice systems of Uruguay, we developed a geospatial framework to identify yield-limiting factors across 55,000 ha annually of cropland over four seasons (2018?2021 harvest years), while also testing for tradeoffs in the environmental footprint related to nitrogen (N) fertilizer use. Our application of geographically-weighted random forest models showed that crop management decisions influenced rice yield more than variation in soil properties, highlighting the potential for improved agronomy to boost crop production by 1.4-1.8 Mg ha-1 across regions. Seeding date, variety, P rate, and K rate were the most important variables controlling yield, but with significant variation across fields. When these factors were optimized by farmers, the risk of environmental N losses or soil N mining did not increase, highlighting the potential for sustainable intensification by improving N use efficiency. These findings present a pathway for harnessing the benefits of increasingly available on-farm data to identify yield-limiting factors while minimizing negative environmental externalities at the field-level. To enable the development of such geospatial frameworks in other regions, new partnerships are required to engage stakeholders and promote data sharing and collaboration among farmers, researchers, and industry, helping guide regional extension programs and orient future investments in agricultural research. © 2024 The Authors MenosABSTRACT.- Advances in technology and analytics to support data-driven agriculture has important implications for global food security and environmental sustainability.
