On six different fertilization tests in pastures in Gallura (Sardinia) fertilized to a constant N (kg/ha O - 30 -60-90- 120-150) and P2O5(O - 45-90-135- 180-225) ratio (1:1,5), the production and distribution were surveyed. The stocking rates per/ha in standard ewe and the relative allowed milk yield with held stocking rates and yield were compared; the former were determined by the cilpping method and the latter by the animal method on identicaI fields fertilized with the average N and P2O5dose.

Abstract
On six different fertilization tests in pastures in Gallura (Sardinia) fertilized to a constant N (kg/ha O - 30 -60-90- 120-150) and P2O5(O - 45-90-135- 180-225) ratio (1:1,5), the production and distribution were surveyed. The stocking rates per/ha in standard ewe and the relative allowed milk yield with held stocking rates and yield were compared; the former were determined by the cilpping method and the latter by the animal method on identicaI fields fertilized with the average N and P2O5dose. Fertilization costs and relative functions of production were calculated.| File | Dimensione | Formato | |
