Manures check fertiliser bills
SAVE money on fertiliser bills by taking account of organic manures and finding out soil nutrient status, says fertiliser maker Kemira.
With soil tests costing only £7-£8, the companys technical manager Howell Richards is surprised at how many producers fail to test. "It seems a small investment to ensure you only buy the required fertiliser."
In general, higher stocking rates result in higher nitrogen needs, but lower phosphate and potash requirements, he says. "Some 70% of P and K from compound feeds passes back on to land via organic manures. If you do not account for this, you will over-fertilise and that is bad economically and environmentally." *
