Figure 8. Primary productivity of forage resources in Cropland Pampas. Primary productivity for each county is derived from Negri (2000). Inset graphs show the primary productivity (kg dry matter ha-1 day-1) seasonality of three different locations for a Tall fescue crop (Festuca arundinacea, open squares and black line) and a Lucerne crop (Medicago sativa, close circles and blue line). Based on Chamber of Seed trade data.
