Overview

Resowing pastures is expensive and risky. Unfortunately, sown perennial pastures thin out over time, reducing productivity and providing an opportunity for weeds to increase.

However, there are strategies that can be used every few years to encourage seedling recruitment in perennial ryegrass and cocksfoot, resulting in new plants without having to resow. This eLearning module outlines some of those strategies. 

References and further reading are available in the Materials tab.

Learning objectives

At completion of this module, you will:

  • understand which species actively recruit seedlings 
  • understand how to manage seedling recruitment 
  • understand how to maximise seed fall 
  • understand how to encourage and protect germinating seedlings.
