Argentina and the coming collapse of its soils

Fertilizer companies souldn't take South America as a whole: every country has its own way when it comes to feed its crop.

Let's have a look at those four grain producers:

 Why Argentina's consumption never took off?

Argentina is blessed with phosphorus and potassium rich soils. As president Kirchner said in 2008, soybean "grows like weed" . Indeed, with only 50 Kg/ha, wet Pampa farmers usually get a more than decent yield with soybean (average of 3 tonnes/Ha).

But how long is this supposed to last? Argentine farmers have been far too careless with their soils over the last decade. The nutrient balance speaks for itself:

Yields are condemned to collapse if Argentine grain producer don't startt to fertilize seriously. They  have to switch from that short term, profit oriented vision to a sustainable, technified agriculture.
