Climate and Pasture Growth

PASTURE GROWTH RATES (PGR)  ****

 

These are measured in terms of the dry matter content (DM) of the pasture. This is then express ed in terms of

Feed on Offer (FOO(in Kg Dry Matter/ha) ), Total Dry Matter (TDM,Kg DM/ha)  or pasture growth rate (PGR, Kg/ha/day).

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.

 

Feed On Offer in years 2010 (wettest) , 2005 and 2006 (driest) and in 2016 Until April10

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.

RAINFALL ****

For a review of a century or more  years of weather records for the property and district click on Climate for Godolphin.

The only surviving records of rainfall taken at either Godolphin or Cadira come from 1942 are shown below. Recordings  since May 2006 have been collected using an automated weather station.
