ABSTRACT.
We estimated timber investment returns for 22 countries and 54 species/management regimes in 2017, for a range of global timber plantation species and countries at the stand level, using capital budgeting criteria, without land costs, at a real discount rate of 8%. Returns were estimated for the principal plantation countries in the Americas?Brazil, Argentina, Uruguay, Chile, Colombia, Venezuela, Paraguay, Mexico, and the United States?as well as New Zealand, Australia, South Africa, China, Vietnam, Laos, Spain, Finland, Poland, Scotland, and France. South American plantation growth rates and their concomitant returns were generally greater, at more than 12% Internal Rates of Return (IRRs), as were those in China, Vietnam, and Laos. These IRRs were followed by those for plantations in southern hemisphere countries of Australia and New Zealand and in Mexico, with IRRs around 8%. Temperate forest plantations in the U.S. and Europe returned less, from 4% to 8%, but those countries have less financial risk, better timber markets, and more infrastructure. Returns to most planted species in all countries except Asia have decreased from 2005 to 2017. If land costs were included in calculating the overall timberland investment returns, the IRRs would decrease from 3 three percentage points less for loblolly pine in the U.S. South to 8 percentage points less for eucalypts in Brazil. © 2020 The Authors |

ABSTRACT.- Furrow irrigation systems have been widely evaluated around the world. However, there is no national data indicating how efficient furrow irrigation is under Uruguayan conditions. The objective of the present work was to evaluate the performance of a system of furrow irrigation in two different soils texture. Seventeen irrigation events were analyzed in sugar-cane cultivation in northern Uruguay during 2016-17 and 2017-18 irrigation seasons. The water advance and recess curves were determined; flow rate during irrigation and runoff were monitored. The maximum furrow length studied was 100 m and the average slope was 0.24%. Application efficiencies in both types of soils were observed above 75%. These field data were compared with data simulated by the WinSRFR model, where high correlations were observed in the results of water application efficiency, distribution uniformity and runoff. These first results encourage to continue working in the efficient use of water, not only thinking about a better use of the resource but also in less loss by run-off, and therefore, less possibility of contamination and lower cost of energy and labor. .-.-.-.-.-.-.-.-.-.-.-. RESUMEN.- Los sistemas de riego por surcos han sido ampliamente evaluados en todo el mundo. Sin embargo, no hay datos nacionales que indiquen cuán eficiente es el riego por surcos. El objetivo del presente trabajo fue evaluar el desempeño de un sistema de riego por surcos en dos suelos de diferente textura. Se analizaron 17 eventos de riego en cultivos de caña de azúcar en el norte de Uruguay durante las temporadas de riego 2016-17 y 2017-18. Se determinaron las curvas de avance y retroceso del agua, se monitoreó el caudal durante el riego y el escurrimiento. La longitud máxima de surco estudiada fue de 100 m y la pendiente promedio fue de 0,24%. Se observaron eficiencias de aplicación en ambos tipos de suelos superiores al 75%.
