Get to grips with green manure and make your gardening more eco-friendly by using this natural fertilizing method
For soil cover or green manure use, N. phaseoloides is normally sown with a sowing density of 4.0 kg seed per ha, [13] which is similar to 32 – 35 seeds per m 2, depending on the seed weight. When sowing pastures with a high weed pressure the number of seed can reach up to 70 seeds per m 2 when there is a high weed pressure.
[3] [4] It is mainly used as green manure to improve soil fertility due to its fast growth, high biomass production and ability to convert large amounts of atmospheric nitrogen into a usable form for plants. [5] [6] [7] Other applications include production of high quality forage for livestock and it is a source of fuel-wood. [8] [9]
For instance, sheep manure is high in nitrogen and potash, while pig manure is relatively low in both. Horses mainly eat grass and a few weeds, so horse manure can contain grass and weed seeds, as horses do not digest seeds as cattle do. Cattle manure is a good source of nitrogen as well as organic carbon. [3]
