Lost the knack of growing good sub clover
With a focus on perennial grass management and rotational grazing, farmers are losing the knack of growing good sub-clover. Farmers remain either unaware of lost production or they suspect their sub is underperforming, but don’t know why or how to get it back.
While there can be a range of reasons for poor growth, it’s now easy to pinpoint why content is low using a new factsheet SFS has compiled for MLA called, “How do I determine why my sub-clover is underperforming?”
With a rule in and rule out table, it takes you through the most common reasons for poor growth and what tests you can do to confirm diagnosis.
The top reasons are repeated poor seasonal conditions (poor spring finishes or years of false or late breaks), less desirable soil conditions (eg. Phosphorous levels deficiency) and grazing management (eg. Pasture lightly grazed in winter and early spring).
Once the reason has been identified and confirmed, then details of how to fix it is available in supporting factsheets.
Other new sub-clover factsheets include, “How to:” optimise production, manage grazing for establishment and seed set), manage soil health, id sub-clover cultivars and replace troublesome or poor performing cultivars.
Search for them on the MLA website for sub-clover or contact SFS.
At this time of year, keeping pastures short (3 to 5cm) over winter, creates more leaves, which in turns creates new sites for flowers to emerge once day length increases. More flowers, puts more seed in the bank to strengthen reserves for when seasons are not so favorable.
