Nitrogen – microbial mineralization & fixation
Nitrogenous fertilizer production relies on non-renewable resources in a costly process that often makes them the most expensive input into conventionally managed Australian dairy pastures.
The transition towards sustainable farming practices naturally involves a move towards taking advantage of renewable nitrogen sources through the processes of ‘mineralization’ and ‘fixation’.
A steady-state nitrogen suppply - mineralization & fixation
Healthy well aerated soil rich in microbes, earthworms, dung beetles and other macrofauna provides an environmrent that boosts the growth of clover, sub-clover and pasture legumes that maximise atmospheric nitrogen fixation and mineralization of organic nitrogen.
In this video Terry Stokes speaks with Australian organic dairy farmer Liz Jordan about the transition to organic dairy farming, the use of organic fertilizer inputs, nitrogen fixation and the benefits she has experienced in cattle health, farm production and farm profits.
