Nitrogen Fixing Grass Seed Mixtures Organic & Conventional

Reducing bagged nitrogen

The table below highlights the importance of herbage legumes in organic grassland management, particularly the role of Lucerne and red clover in the fixation of nitrogen.  The contribution of N from soil organic matter should not be over-looked and is a reminder of the value of composted FYM in adding organic matter and humus.

All soil organisms depend on organic matter as their food source.  Slurry, which supplies a large proportion of readily available N, is key to maintaining a healthy population of soil organisms in the top 6 inches of soil.  pH should be maintained at 6 to 7 and twice yearly use of an aerator will benefit drainage and amplify worm numbers
