How does everyone work out there costs and profits of these crops? More so on the dry matter production and profits you can make from the stock prior to harvesting? What would be a general rule for how much dry matter a wheat crop would produce through grazing prior to locking it up and what sort of price would you put on it? Just trying to do some costings and my figures don't seem to add up to what I think they should
To simplify it =Grazing it to locking it up, its a matter of season if the spring is good you wont need to graze it, if its tough you will be glad to have it for hay or grazing. win win situation plenty of value in dual purpose the stock will do better and turn out better offspring easier.
Its probably easier to come from a straight livestock operation and introduce some cropping say 10 % of your land. Sowing tried and proven long season varieties early. This 9 times out of 10 will halve the number of paddocks running stock through autumn ,which in turn sets you up to get through winter with extra pasture. By early spring you should be able to decide off conditions and forecasts if you can shut up all or some or none of your crops, depending on feed needs . If the crops keep improving extra nitrogen can be added and let them finish. If they look like a possible failure hay can be cut or stock introduced either way value is again added to your initial input.
AS for doing the math's some people do it. I just wait for the bank balance to show it.
