A typical output of both FOOD and TDM  for 2 very dry years (2005 and 2006) and one very wet year (2010)  is

shown below. Thte current year (2016) is looking to be a drought year.

The results for both FOO and TDM in 2016 to mid April are compared to these same three years in the fours charts below. (Note the scales on each chart are different !)  April-May is a critical period to have good soil moisture in this region as with the advent of frosts and low daytime temperatures around this time there will be little pasture growth even if good rain is received after the end of May.
