Short-rotation plantations have been suggested to develop renewable energies in South America. Our study evaluated the biomass production of Eucalyptus benthamii, E. dunnii and E. grandis plantations at stocking densities of 2220, 3330, 4440 and 6660 trees ha-1 in the North (Tacuarembó) and West (Paysandú) of Uruguay,
over a 76-month period. The species survival was not related to planting density, and the highest mortality rates occurred at Tacuarembó. The effects of tree competition were more evident for E. grandis. At Tacuarembó site, the average survival of the species were: 57, 57 and 46% at age 76 months for E. benthamii, E. dunnii and E. grandis, respectively. Survival rates were similar for the different planting densities, with ranges between 50 and 57%. At Paysandú site, the average survival of the species were: 83, 86 and 75% for E. benthamii, E. dunnii and E. grandis, respectively, with a range from 78 to 84% for different planting densities. Weather conditions (temperature and rainfall) were similar at both sites throughout the evaluation period. Wood density and individual and total biomass weight (kg tree-1 and Mg ha-1,respectively) were evaluated sampling destructively 2592 trees and logarithmic biomass equations were developed using the diameter at breast height (cm) and total height (m) of the trees. Wood density increased with the age of the crop only at Paysandú. On average, wood density increased from 0.405 g cm -3 at age 18 months to 0.497 g cm -3 at age 76 months. The highest wood density was observed at 76 months on E. benthamii (0.413 and 0.431 g cm -3) and E. dunnii (0.496 and 0.539 g cm -3) at Tacuarembó and Paysandú, respectively. Age had no effect on the wood density at Tacuarembó. The stem biomass showed an inversely-proportional relationship with the planting density. Individual stem biomass was higher for E. grandis (81 and 74 kg tree -1 on average at Tacuarembó and Paysandú, respectively) than for the other species. The highest biomass per hectare was achieved for the highest planting density, specifically for E. dunnii (193 Mg ha -1) and E. grandis (203 Mg ha -1) at Paysandú and for E. dunnii (157 Mg ha -1) at Tacuarembó. At both locations, the effects of contrasting planting densities on biomass production increased throughout the rotation.

Abstract:
Despite increasing calls for the sustainable intensification (SI) of agriculture, environmental impacts associated with historical patterns of yield increase remain poorly understood, particularly involving multiple sustainability indicators. The objective of this study was to examine the sustainability of rice intensification in Uruguay from 1993 to 2013. National rice production and crop management records were used to estimate energy, nitrogen, water, and carbon footprints and agrochemical contamination risk for the rice phase of typical rice-pasture rotations in Uruguay. Results suggest that increases in national production were achieved with simultaneous increases in net energy yield and water use efficiency (56% and 41%, respectively). Although carbon footprint per unit of production decreased (#1;30%),
potential nitrogen losses increased (37%) and elevated agrochemical contamination risk occurred in specific years. This study highlights the potential role of improved agronomy in balancing food production and environmental goals, while also indicating that similar holistic assessments are needed for other rice growing regions to better evaluate SI strategies and quantify potential tradeoffs. |
