Efficiency of phosphorous fertilizers on pastures stablished in Chilean Andepts
|Elías Letelier A.1|
Two long term trials on the application of phosphorous to pastures on Chilean Andepts ("Trumaos") are analysed. Both show that the efficiency of P applied was about 50 to 60%, when the rate of application of P was about 50 kg/ha/year, or less.
