This is a guide to the value of phosphate & potash removed from the soil when straw is removed from a field. Cereals and pulses can vary in value(eg. oat straw is worth considerably more than wheat straw).
The cost of baling, carting and replacement fertilisers are not included in this calculation.
The best way to calculate straw value is per tonne.
When inputting phosphate and potash values the app works in all currencie's.
Potash content can vary depending on rain fall,crop maturity and previous chemical applications.These figures are for guidance only.
