Opportunity cropping has been shown to reduce mean annual deep drainage compared to long fallow systems. A question that remained was the effect of added fertiliser nitrogen under each of the cropping systems and whether it would make a significant difference to amounts of deep drainage and to profitability. Estimates of crop yield and deep drainage results were generated using the APSLM (Agricultural Production Systems Simulator) cropping systems model, to compare long-fallow wheat/sorghum and two opportunity-cropping scenarios on a vertosol on the Liverpool Plains using rainfall data from 1958 to 1997. The results showed that fertiliser nitrogen did have a significant effect on deep drainage and gross margin under each cropping system. However, higher... |

Three 54ha "farmlets" were established in 2000 near Uralla, NSW to trial high input, moderate input and intensive rotational grazing systems. A representative farm approach was used to interpret the profitability results of the trial from July 2000 to June 2005 at a commercial scale level to make research results more relevant to farmers. At the gross margin level, the high input farmlet had the highest annual gross margins, but this farmlet had the worst whole farm performance. These contrasting results support the claim that annual activity gross margins cannot alone indicate the profitability of an investment. This demonstrates that whole farm analysis is the most suitable method to assess different grazing systems. |

A number of farming systems projects are currently being conducted in the north eastern cropping region of Australia. These are jointly funded by the grains industry and state government R&D agencies, and conducted by the latter with some involvement of private industry. The issues which were the genesis of these projects are basically technological (ie productivity-enhancement) to maintain or improve farm income over time, and environmental to redress natural resource degradation associated with the current system. This paper is concerned with the analysis of results from these projects to provide information which helps grain growers in making decisions. In particular, we aim to consider the issues to be analysed and the characteristics of the... |

A whole farm budget for a representative farm in the Lower Namoi Valley in northern NSW was used to analyse the financial implications of a comparative rotational experiment of four cotton-based rotations conducted in recent years at the Australian Cotton Research Institute, near Narrabri. The model was used to compare the rotations, which highlighted the importance of crop selection for the financial performance of the business. Apart from providing a broad brush picture of financial performance, the model also had a stochastic component which was used to analyse the effect of variable commodity prices on the whole farm profitability of each rotation. Mean results indicated a positive return for all rotations within the representative farm budgets for the... |
