HOW TO SCORE
Walk the field and assess grass content.
An Index 3 field will have a total of 50-60% sown, productive species (including any clover at less than 10%, if sown).
It will also have approximately 40% weeds or gaps.
There will be docks covering around 20-25% of the pasture and at this level it means you are losing up to a quarter of yield from it.
WHAT THIS MEANS
At Index 3, the field is in an ideal situation to correct the problem and extend the life of the pasture.
WHAT TO DO
This is an ideal stage to correct the problem.
Between March and April, the docks are healthy and actively growing, with good weather conditions. Use an overall spray such as Dockstar pro.
Remove the docks and then overseed with quality grass seed to get productive seeds back into the sward as before weeds thrive in bare earth.
Follow manufacturers instructions in regards to when to over sow after using a herbicide to avoid any issues with young grass seedlings.
This is also an ideal time to add clover for added life duration of the sward and should extend the life of the sward by a couple of years.
