Costings would have to be adjusted for cultivations made using owned machinery. Forage maize has been costed with a plastic mulch included at the time of establishment costing around 270 per hectare. This represents an approximate conacre charge for 1 year. Some crops have shorter growing seasons than others, however it has been assumed that land is required for a full year. Depreciation on silos and storage buildings has been included where appropriate.
Every farm is different Yields can vary considerably.
This has a very large effect on the cost per kilogram of dry matter produced. Weather conditions, soil type and husbandry methods will all have an impact on the yield produced. Remember - these figures are only a guide and should be tailored to individual circumstances. The choice of crops on individual farms is likely to be limited by soil and climatic conditions.
