Site Classes– Applicable to grassland

Grassland production is limited by growing conditions, in particular the quantity of rainfall between April and September and soil type. The combined effect of these factors defines the site class.

	Average April – September rainfall mm (inches)
Soil texture	More than 500	425–500	350–425	Less than 350
