Evergreen Landcare’s straw mulching process is very effective in preventing sediment run-off in heavy rains. Sediment run-off is impeded by at least 80%.
The process involves mulching straw and blowing it over the ground surface until it forms a continuous open textured mat.
The covering of straw provides a microclimate of even temperature and moisture content at the ground surface.
The open weave of the straw allows light and water into the seed bed providing ideal conditions for germination. The straw mulch prevents drying out due to the effects of frost or sun and wind.
Using this method new grasses can be established even in June/July at altitudes of over 500 metres above sea level.
Straw mulching can be used in conjunction with either Hydroseeding or conventionally sown areas.
