Table 6 Financial outcome for the MAF base model and the organic farming systems under various scenarios
2002
"... In PAGE 21: ... Organic with premium model: same as the organic production system with returns based on a premium of 50 percent for both lamb and beef, with 60 percent of lambs and 90 percent of cattle finished to specification. Changes in stock policy and specifically a higher cattle ratio of breeding cattle and cattle mated as rising 3-year-olds had the single biggest effect on the profitability of the organic farming system ( Table6 ). A change in stock policy, assuming static production and prices, results in a reduction of $65,361 in gross farm revenue, and a decline of over 50 percent in economic farm surplus.... ..."

Table 6 Characterizing Production Systems
"... In PAGE 46: ... Furthermore, they shed little light on the scale of agroecosystem enterprises, the temporal and spatial arrangement of production system components, and other agro- nomic and management practices that determine the local ca- pacity of each agroecosystem to deliver goods and services in a stable and sustained manner. Table6 lists a number of attributes that might be used to characterize agroecosystems, as well as some typical attribute values for two polar cases of low and high external-input production systems. But the range, complexity, and time dependent nature of such information generally make... ..."
Table 23 Infrastructure, resources: implications of widespread adoption of organic farming
2002
"... In PAGE 62: ...7.1 Infrastructure and resources There was a general consensus that the agriculture service industry would need to change in response to widespread adoption of organic farming ( Table23 ). The number of suppliers of a range of organic products would increase, along with factory processing capability.... ..."
Table 5. Nitrogen budgets of recently converted and developed dairy farms within the Bog Burn catchment

"... In PAGE 15: ...e in a developed state (i.e. more than 10 years since conversion to dairying). However, many of the dairy farms in the catchment have been in dairying for less than 10 years. Table5 lists the N budgets predicted for a recently converted dairy farm, compared to a developed dairy farm within the Bog Burn catchment. Both farms were assumed to have the same farm management, production, fertiliser and supplementary feed inputs.... In PAGE 15: ... Both farms were assumed to have the same farm management, production, fertiliser and supplementary feed inputs. The N budgets presented in Table5 show that the recently converted dairy farm system was estimated to have higher N inputs due to increased N2-fixation and much higher immobilisation of N into soil organic matter. Gaseous N losses and leaching/runoff losses are slightly higher in the developed system.... ..."

Table 26. The effects on the farm Nitrogen budget of converting sheep and beef farms to forage-cropping farms in the Toenepi catchment
in Disclaimer
2002
"... In PAGE 32: ....3.4 The effects of integration of cropping Conversion to cropping is a viable option for sheep and beef farmers within the Toenepi catchment as an alternative to intensification. Table26 presents the N budgets for a forage- cropping farm growing maize silage followed by oat silage, for years one and 10 after converting from a sheep and beef farm system. To achieve this change in farm systems, fertiliser inputs were increased (especially Nitrogen inputs) with a greater Nitrogen input in year 10 than in year one after conversion.... In PAGE 32: ... Less Nitrogen was required in year one after conversion due to a high amount of Nitrogen being mineralised after cultivation. Table26 shows the increase in fertiliser N from 6 (sheep and beef) to 140 kg N/ha/yr in year 1,and to 280 kg N/ha/yr in year 10. Net mineralisation of Nitrogen occurs after conversion to cropping due to cultivation and there is a significantly greater input of Nitrogen in the first year after conversion than in year 10.... ..."
Table 1 Mean values of physical environment variables, by system
"... In PAGE 18: ... Thus, we could expect less organization where there are many private wells. Table1 shows that the most wells were found in the oldest systems: Chambal (average of 7 p er minor command), followed by KRS (average of 6 per sample site ), and lowest in IGNP (1 per site), where water tables are lower, and farmers have been settled for less time.... ..."
