Grass cover is measured in amount of dry matter available per hectare (DM/ha) and the target should be for that cover to sit between 2,500 and 3,000 when cows enter the paddock. At this height, the grass will recover well and have time to grow to the third leaf stage before it is grazed again.

When running several bulling groups, each group would have their own allocated area and their own set of paddocks, which they will rotate around. More specific demand percentages can be used and are available from AHDB or independent advisors. Slow Rotational Grazing: 2 or more pastures with moves from every 2 weeks to every few months. compaction) have not been fully investigated then return on investment could be severely reduced. Rotational burning to minimise patch grazing. Measuring with a plate meter © Tim Scrivener. The desired period for rest and regrowth varies for different times of the year and under different conditions.

When she's not helping farmers, ranchers and land managers on-site, she writes articles, and books, and edits videos to help others turn their livestock into landscape managers. Rotational grazing is dividing the pasture area into several small paddocks. Absolutely zero common ground!!! This can be measured with a plate metre or sward stick, but for simplicity, can also be talked about in terms of the height of the grass.
