Abstract
The build-up in general soil fertility and productivity in eastern Southland and West Otago are discussed, with references to indices such as sheep numbers, grassland fertilized and fertilizer sown. Annual and seasonal dry matter production figures from browntop dominant and ryegrass dominant swards are compared. Reference is made to the decreasing importance of winter fodder crops in the region as soil fertility has built up and as pasture growth has been extended. Wintering systems for ewes, hoggets and cattle using grass, hay and grain are discussed. The implications of a rotational grazing system with ewes and lambs in early spring are reviewed, and topics for future research to try and harvest the spring-summer flush of growth are suggested.
