Cover crops - the advantages of Sunn hemp

There is increasing interest in the use of different cover crop species and mixes of cover crops to improve soil health and productivity in the Australian vegetable industry.

In this video, Dr Kelvin Montagu will provide some guidance on sowing, management, and how best to terminate the cover crop. 

Some of the advantages of Sunn hemp include nitrogen fixation, strong weed suppression and a tolerance of hot summers. However, it does need plenty of water to thrive in hot summer conditions, so, without access to this, sorghum will be the better option.
