Abstract
Barley leaf rust, caused by Puccinia hordei,has been present generally at low incidence for over 20 years in Uruguay. During 2005 and 2006, the disease reached epidemic levels, causing heavy losses in grain yield and grain size in susceptible cultivars if chemical control was not used. The increase in importance of the disease was associated with the appearance of a new race of P. hordei, virulent to widely grown barley cultivars. The P. hordei population is relatively stable in the Southern Cone of America, only three races having been identified since 1995. The third race acquired virulence on Rph9.z, which is probably present in Defra-derived cultivars, widely used in Uruguay and
Brazil. Sources of resistance, mostly adult plant resistance identified since 1999, have been routinely used in crosses in the barley
breeding program of the Uruguayan National Institute for Agronomical Research (INIA)for the last 10 years. Combining information
from field nurseries and seedling infection type data allowed identification of highly effective resistance, expressed as low levels
of disease under heavy leaf rust epidemic challenge. The resistance of these materials derives from European germplasm. The
number of resistant advanced lines increased significantly after three cycles of selection for resistance under heavy disease pressure
during 2004?2006, which indicates that an important genetic advance in breeding for leaf rust resistance was achieved. |

Carbon net emission is a critical aspect of the environmental footprint in agricultural systems. However, the alternatives to describe soil organic carbon (SOC) changes associated with different agricultural management practices/land uses are limited. Here we provide an overview of carbon (C) stocks of non-forested areas of Uruguay to estimate SOC changes for different soil units affected by accumulated effects of crop and livestock production systems in the last decades. For this, we defined levels based on SOC losses relative to the original (reference) SOC stocks: 25% or less, between 25% and 50%, and 50% or more. We characterized the reference SOC stocks using three approaches: (1) an equation to derive the potential SOC capacity based on the clay and fine silt soil content, (2) the DayCent model to estimate the SOC stocks based on climate, soil texture and C inputs from the natural grasslands of the area, (3) an estimate of SOC using a proxy derived from remote sensing data (i.e., the Ecosystem Services Supply Index) that accounts for differences in C inputs. Depending on the used reference SOC, the soil units had different distributions of SOC losses within the zones defined by the thresholds. As expected, the magnitude of SOC changes observed for the different soil units was related to the relative frequency of annual crops, however, the high variability observed along the gradient of land uses suggests a wide space for increasing SOC with agricultural management practices. The assessment of the C stock preserved (CSP) belowground and the potential for increasing C accumulation or sequestration (CAP) are critical components of the C footprint of a given system. Thus, we propose a methodological road map to derive indicators of CSP and CAP at the farm level combining both, biogeochemical simulation models and conceptual models based on remote sensing data. We recognize at least three critical issues that require scientific and political consensus to implement the use of this propose: (1) how to define reference C stocks, (2) how to estimate current C stocks over large areas and in heterogeneous agricultural landscapes, and (3) what is a reasonable/acceptable threshold of C stocks reduction.
