| This study used information about a farm in the Victorian Mallee during the period 1998 – 2005 to analyse the profitability of investing in Precision Agriculture and Site-Specific Crop Management technology and farming systems. Two equipment guidance systems were evaluated. Both guidance systems earned more than 8 percent real return p.a. on the extra capital invested. A Real-Time Kinetic (RTK) guidance system with a precision of 2 cm and a capital cost of $50,000 was less profitable than a Sub-Metre guidance system with 20 cm accuracy and costing $20,000. Producers investing in RTK guidance technology would be well-paid to also adopt supporting management practices that enhance crop gross margins or provide other benefits. The capital cost of GPS... |

| This study uses a farm in the Victorian Mallee over the period 1998 2005 to analyse whole-farm profitability and risks of investing in Precision Agriculture and Site-Specific Crop Management systems. To answer the research questions, a model to predict yield under PA management is developed to simulate paddock and activity gross margins. Analysis is conducted that enables judgements to be formed about merit of investing in some PA technologies. The case study farm comprised 1400 hectares, with 900 hectares of cereals cropped each year. In this case, investment in Zone Management technologies did not meet the required return on capital. Using the relationship of paddock variability to profitability derived from the simulation data, in a year with median... |
