ABSTRACT.
A hedonic model of feeder and replacement cattle prices in Uruguay was specified to include both permanent agroecological factors (soil productivity and water holding capacity [WHC]) and nonpermanent factors (season, available soil moisture, and pasture conditions) as explanatory variables. Results indicate that predominant agroecological endowments (soil characteristics, water availability, and average seasonal climatic conditions) determine geographic price patterns for cattle produced under extensive production systems. In addition, weather variability and especially extreme events have an important impact on short-run cattle markets. As pasture conditions improve or precipitation increases (e.g., both soil moisture and surface runoff), livestock prices tend to fall, ceteris paribus. A cattle price gap between different regions of Uruguay based on permanent resource endowments (e.g., soil productivity and WHC) and temporary agroecological conditions exists and is illustrated using a series of iso-price maps. The hedonic price model also included various cattle characteristics and marketing conditions as explanatory variables. Grass-fed cattle in Uruguay are not a homogeneous commodity; video auction prices incorporate information about a range of agroecological factors that influence cattle production, marketing patterns, as well as perceived and actual cattle quality and performance.

Since 2001/2002 there has been a formidable expansion of annual crops in Uruguay which has determined changes in land
use, with a strong expansion of soybeans (Glycine max) under no-tillage. Improperly managed crop production systems can
be an important nonpoint source of pollution, accelerating eutrophication of surface waters resulting from nitrogen and phosphorus
(P) inputs. Nutrient losses depend on many factors such as climate, soil characteristics and management practices. Thus, the
objective of this work was to estimate the annual P loss on a cropping system and to determine the main factors contributing
to such losses. Runoff plots were located at the Experimental Station of the National Agricultural Research Institute in Colonia
(INIA "La Estanzuela"), Uruguay (34º25´S, 58º0´W) during the period 2013-2014. Plots were under a Vertic Argiudoll soil with
18.5 mg/kg P-Bray I on the first 7,5 cm, a 3% slope and available water content of 92.7 mm on the first 56 cm of soil depth. The
rotation established was soybean - fallow/cover crop, non-fertilized for over 5 years. The amount of runoff water was measured
for 23 rainfall events and analyzed for soluble P. During that period the soybean yield was similar to the national average yield
and the annual P loss was 0.5 kg/ha. Available water, precipitation, maximum rainfall intensity and runoff explained most of the
variation in P runoff losses. Rainfall events of high magnitude and intensity on soils with high available water were identified as
the events that produced higher water and P runoff. On the other hand, the model that best fitted P losses was just explained by
rainfall and runoff (P = - 9.99 + 0.95*rainfall +21.56*runoff; R2=0.73). Overall, our results indicate that these soybean-cover
crop systems under no-tillage, on soils with proper nutrient status and non-fertilized for a long time seem to be economically
and environmentally adequate management systems MenosSince 2001/2002 there has been a formidable expansion of annual crops in Uruguay which has determined changes in land
