ABSTRACT.
Cropland area in Uruguay, mostly soybeans, increased 300% during the last decade due to expansion to new areas. Although no-tillage practices are generalized among farmers, soil erosion is still a major environmental and economic issue. A predictive tool as the Water Erosion Prediction Model Project (WEPP), based on soil processes, has never been used in Uruguay. The objective of this research was to evaluate the soil erosion impact of various managements of intensive agriculture on Mollisols of Uruguay, applying the WEPP erosion model. The model was fi rst adjusted and validated for annual erosion estimates of an Abruptic Argiudoll (Nash Sutcliffe (NS)= 0.81 and R2 = 0.89) and a
Vertic Argiudoll (NS= 0.86 and R2 = 0.90), and later applied to evaluate three Mollisols and one Vertisol with different soil managements. Treatments combined no tillage (NT) and reduced tillage (RT) with different crop rotations. Crop rotations were: continuous soybean (CS), soybean-wheat (SW), soybean-winter cover crop (S-Cover crop), cornsoybean-wheat-3/4 yr pasture (CSW-PPP/PPPP), and corn-soybean-wheat-soybean-wheat-3/4 yr pasture (CSWSWPPP/PPPP). Soil erosion under RT system or CS was always above 7Mg.ha-1 (T value). Pastures inclusion under NT showed values below 7 Mg.ha-1.WEPP simulated an average erosion rate below T for SW rotation with NT (100m; 3% slope) in three of the four soils studied. However, by varying the slope and the length of the hillslope, the range for which the average annual erosion remains below this level is limited (only 3% - 4%). Moreover, for those hillslopes
whose average annual erosion does not exceed the T value, there is still approximately a 25% probability that this may occur any given year. Our work highlights the potential of using WEPP in the development of criteria for assessing sustainability of soil management, alternative to T value of average annual erosion units, including risk analysis MenosABSTRACT.

Abstract: Commercial tree plantations cover around a million ha in Uruguay, mostly with stands of eucalypt and pine trees. Uruguayan forestry was free of serious insect pest until the end of the twentieth century. Beginning in the 1990s, both forestry area and international trade experienced an exponential growth, followed by an increase of invasive insect records. More than half of the pests currently affecting Eucalyptus entered the country after 1995. The use of pesticides is greatly restricted, provided around 90% of the plantations are under FSC and/or PEFC certification schemes. Hence, the Uruguayan forestry has relied mainly on silvicultural and biological control to suppress insect pest populations. Biological control for forest insect pests in Uruguay can be tracked back to 1941. Currently, biological control with entomophagous or entomopathogenic organisms has been, or is currently being, implemented for eight insect pests in plantations in Uruguay. More than five parasitoid wasps and a nematode have been released and installed in the field. There are also at least two cases of introduction of entomophagous organisms simultaneously with the pest. I discuss the future of biological control in Uruguay, focusing on the advantages it possesses and the challenges it faces under the current pest status. |
