Straw harrowing is the best way to encourage weeds to germinate. Creating a quick and effective germination of weed seeds is essential in any direct drilling or min till establishment system.
The Claydon Straw Harrow will encourage weeds to germinate quickly from the same depth at the same time. Because weed seeds are mixed into the top 30mm of soil, all weeds will germinate.
By mixing up and exposing damp chaff and lying straw to sunlight the Claydon Straw Harrow will dessicate slug eggs and reduce slug activities on the surface of the soil.
Passing over oil seed rape stubbles every two weeks will hoe out cotyledons which will reduce this food source for slugs.
The Straw Harrow can be used in conjunction with the Claydon TerraStar. The TerraStar is another stubble management tool which creates slightly more tilth at depths of up to 3cm, and is also able to operate when soil is harder and drier after harvest.
