【 摘 要 】

Concepts behind the best management practices of rangeland improvement include production, economics, as well as social and environmental aspects. Although revenue in rangelands can be increased by fertilization, total production cost can increase and as a result, net benefit may reduce due to increase in fertilizer application cost. This study examined differences between three economic analysis models (EAM): total revenue based on i) hay yield (HY), ii) conversion rate of consumable crude protein to meat on the hoof in cow-calf (CPM) and iii) yield and relative feed value (RFV) index as a new opinion to highlight the economic aspects related to the N (0, 60 and 120 kg ha-1), P (0, 60 and 120 kg ha-1) and K (0 and 80 kg ha-1) fertilization (NPK) in degraded rangelands. For this purpose, a series of data, gathered from an experiment conducted to increase the productivity of degraded rangelands by fertilization were analyzed. The results were most dissimilar for ‘the revenue’ variable and this difference lies in the fact that the EAMs estimated income in different ways. Due to the different revenue measurements, net benefit of CPM was the highest, while that of HY was the lowest. The HAY and RFV models indicate that NPK fertilizers did not increase forage production enough to be profitable for animal production. This study does not strive to suggest one EAM over another; however, it examines the respective models concerning various data and describes underlying characteristics of EAMs to obtain a given increase in net benefit.
