Cattle grazing under Pinus caribaea. 1. Evaluation of farm historial data on stand age and animal stocking rate |
| 520 ## - SUMMARY, ETC. |
|---|
| Summary, etc |
An analysis is made of the animal stocking rate used in commercial Pinus caribaea plantations 2,5-8,5 yr old. Pines were planted at 2,5 x 2,5 m and programmed for clear-cut harvest at 10 yr rotations (pulpwood). Cattle grazing was introduced to reduce weeding costs. Stocking rate in 1983-1985 was 0,67 AU/ha/yr (AU = animal units 350 kg live weight). A quadratic model calculated using 1984 data (S = 0,0108 + 0,385A-0,0418Aø) describes the relationship between animal stocking rate (S) and stand age (A < 9,5 in yr). The model predicts a maximum of 0,89 AU/ha/yr at plantation age 4,5 yr. Grazing started at plantation ages > 2,5 yr; no plantations older than 9,5 yr are grazed. |
