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.

El riego suplementario es una opción estratégica para asegurar la producción de forraje
en un escenario de alta variabilidad climática, pero en Uruguay falta información para generar
coeficientes técnicos de respues ta. Se realizó un experimento con el o bjetivo de
evaluar los efectos del riego y la fertilización N-P en la producción de forraje y composición
botánica de un campo natural de basalto. En el período octubre de 2011 a Junio 2012 se
desarro lló un ens ayo con un diseño de parcelas divididas. En las parcelas mayores se
ubicaron el riego suplementario y el secano, mientras que en las parcelas menores se ubicaron
un testigo sin fertilizar y siete tratamientos de fertilización: una dosis de fósforo (80
kg P2O5.ha-1), tres dosis de nitrógeno (50, 100 y 200 kg N.ha-1) y tres combinaciones N-P
(80 P2O5-50 N; 80 P2O5-100 N; y 80 P2O5-200 N). La interacción del riego con la fertilización
nitrogenada explicó las variaciones a corto plazo de la productividad y composición
botánica de la vegetación. El riego incrementó la respuesta a la fertilización nitrogenada
duplicando la producción de forraje del campo natural y generando condiciones para el
aumento de la contribución de los tipos productivos más valiosos desde el punto de vista
forrajero. |
