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
