If you find
There are crop problems such as soil-borne diseases and deficiencies from a short rotation
Stock leave weeds and overgraze the “good bits”
Allowing a longer gap may allow recovery. A shorter “on” time may allow the benefit (to the farmer) to be gained quickly.
As well as suiting a grazing rotation, this minimizes the problems that would result if there was not a long gap between members of certain plant families.
In a Market garden this may mean you need to have a structured rotation to allow a sufficiently long gap between crops in the same family. For example between potatoes, tomatoes and capsicums in the Solanum family.
In a grazing situation, the combination of a Short hard graze to bring on Grazing shock followed by a Long rest will encourage livestock to eat the weeds as well as the “good bits” and graze the pasture or range to a more even level.
The long rest will allow full recovery and if timed appropriately may force weeds into a less competitive position and give the advantage to the desirable species. This will allow a Competitive crop in the form of a pasture to keep weeds down.
