Lime is important for profit, don't delete it from your budget!
When harvest comes to a finish in many regions, liming is a topic that comes to mind for many growers. Like many of the major investments made, liming is often the subject of lengthy discussion.
Lime is an essential component of all farming systems. Farming involves growing wheat, canola, barley, beef, sheep wool etc, and then selling the produce. All these processes involve exporting alkalinity and liming replaces what has been exported as produce, and the other acids that result from inefficiencies in the nitrogen cycle.
Lime is a commodity required in considerable amounts, and unfortunately it often something that is readily deleted from farm budgets. With lime generally a coastal resource that is required inland, there is further complication from the large freight costs involved when lime use is considered. This is one of the key reasons a red pen is taken to lime in a budget. The decision to slash lime inputs may seem a money saving exercise in the short term, but it is also costing profit. Lime application helps growers remain profitable. The decision to delete lime from budgets should be approached with a deal of caution.
There are vast quantities of legitimate scientific data that confirms unequivocally that lime application is a profitable exercise, especially when targeted to the most acid soils.
