Contenido :  Abstract: During land leveling topsoil of relative higher elevation zones are removed (cut) and deposited in relative lower elevation zones (fill), this operation could have negative impacts on soil conservation and potentially can affect productivity. Although land leveling is an efficient way of increasing water use efficiency and irrigation uniformity, it can be rather expensive and, in some cases, a significant movement of earth may be required. Nowadays, with the technological advancement a new option is available called Land-forming for irrigation (LFI). This alternative method potentially allows smaller soil movement and consequently smaller cutting depths while improving irrigation and drainage conditions without affecting productivity. The hypothesis of this study was that applying LFI can allow a more efficient irrigation than the commonly used procedure done by farmers (Control: no alteration of natural topography) without affecting productivity. For achieving this, a 2-year 2019/2020 and 2020/2021 rice seasons comparison study was done in a semi-commercial field (12 ha) in Uruguay. This was the first time LFI was implemented in this country. For achieving the LFI alternative a soil movement of 104 m3 ha−1 was determined. The depth of cut was in average 0.03 m, with a maximum cut of 0.16 m. The total length and number of rice levees were reduced by 14% and 28%, respectively, compared to the situation this same field would be level using the traditional syste... Presentar Todo

Contenido :  We estimated financial returns and wood production costs in 2008 for the primary timber plantation species. Excluding land costs, returns for exotic plantations in almost all of South America e Brazil, Argentina, Uruguay, Chile, Colombia, Venezuela, and Paraguay e were substantial. Eucalyptus species returns were generally greater than those for Pinus species in each country, with most having Internal Rates of Return (IRRs) of 20% per year or more, as did teak. Pinus species in South America were generally closer to 15%, except in Argentina, where they were 20%. IRRs were less, but still attractive for plantations of coniferous or deciduous species in China, South Africa, New Zealand, Indonesia, and the United States, ranging from 7% to 12%. Costs of wood production at the cost of capital of 8% per year were generally cheapest for countries with high rates of return and for pulpwood fiber production, which would favor vertically integrated firms in Latin America. But wood costs at stumpage market prices were much greater, making net wood costs for open market wood more similar among countries. In the Americas, Chile and Brazil had the most regulatory components of sustainable forest management, followed by Misiones, Argentina and Oregon in the U.S.
