Clip from G & P Hunters - 2/12/11

It was an enjoyable time at Hunters place..There was a discussion on humate and this may be helpful.  

The information on the different humates is below. People should be mindful of the fact that humates are difficult to test reliably and that these results have been produced in different laboratories. Fulvic Acid content was not tested.

Prices vary and the amount of humate being applied can be adjusted for differences in quality. Because of this, it is recomend that Humates be applied at the following rates: 

Australian 3% by weight of fertiliser being applied 

Waimumu 5% by weight of fertiliser being applied 

Roxburgh 7.5% by weight of fertiliser being applied 

Humate is always thoroughly mixed with fertiliser and or lime before application to give maximum opportunity for chelating with applied cations to occur. (This is the bit that the truck drivers love!) 

 

Fulvic Acid and Humic Acid can also be added to foliar mixes in a liquid form 

There is an article on fulvic acid that appeared in Southern Rural Life earlier this year.
