[Pil-pc-oceania] Soil microbes can cut phosphorus costs (farmonline)

[tamara griffiths]

These guys have the products written about ---

I heard about the stubble digester from Dr Maarten Stapper - who was sacked 
from CSIRO because he wanted to use biological farming and not chemical. So 
I looked it up and found these guys!

(not meant to be an adversitement - i'm not connected to these guys in any 
way)

existed?"  Louisa Lawson

>      With the cost of phosphorus fertiliser continuing to sit at record 
>levels and farmers facing unprecedented fertiliser costs of up to $150 a 
>hectare, any means of cutting down costs will be welcomed.
>      Researchers have found that a combination of building microbial 
>activity and monitoring soil phosphorus levels to ensure expenditure is 
>profitable are two good methods of minimising fertiliser bills next season.
>
>      South Australian scientist Ann McNeil, a researcher at the University 
>of Adelaide, says soils contain organic phosphorus and by encouraging soil 
>microbial activity, growers can encourage phosphorus cycling and increase 
>its availability to the plant.
>
>      Traditionally, farmers have accessed in-soil nitrogen reserves, which 
>become available through mineralisation following summer rain or through 
>growing a legume, but have regarded phosphorus as an unavoidable 
>expenditure.
>
>      Dr McNeil says growers can also make use of organic phosphorus in the 
>long-term - with no-till systems improving the soil organic matter doing 
>the best job of making extra P available.
>
>      Dr McNeill's research shows farming practices which build soil carbon 
>also improve organic phosphorus levels and microbial activity.
>
>      However it is not a short-term fix - and that P levels must be 
>maintained to promote microbial activity.
>
>      Even though as little as 20pc of applied phosphorus ends up in the 
>plant, the "lost" fertiliser still has an important part in stimulating 
>microbes and eventually becomes available to plants in other seasons.
>
>      Eighty to ninety per cent of phosphorus in the crop comes from the 
>organic phosphorus reserves in the soil, converted by the soil microbes.
>
>      Dr McNeill says it takes a long time to achieve a nutrient balance in 
>the soil but by encouraging the soil microbes growers can maintain a 
>healthy system with a sustained ability to supply plant-available 
>phosphorus.
