Differences in rooting green manures are huge
Soil compaction and structural damage have a major negative impact on crop yield and quality. In these times of tight fertilization space and increasingly severe weather extremes, the soil structure has become even more important.
An inventory in 2015 showed soil compaction on no less than 45% of all plots. Compacted spots can be removed with great precision during drought and heavy showers. It can be seen, for example, that water storage and infiltration is disrupted, plants have more difficulty rooting and nutrient uptake is hampered. Intensively rooting green manures make room for air and water and can break through disturbing layers.
Big differences
The amount and depth of rooting varies considerably per green manure! Champion in rooting depth is fodder radish† A thick taproot grows at the top of the soil, which creates a lot of space and breaks open superficial compaction. The fine hair roots go up to 2 meters into the ground. As a result, fodder radish also captures many minerals from the deeper layers, which benefit the main crop.
The mix LG Nemaredux In addition to 70% Doublet fodder radish, it also contains facelia and swordlark, which make the rooting extra diverse. This mixture effectively combats beet cyst and chitwood nematodes.
mineral sequestration
Intensive rooting not only ensures an airy, open structure, but also optimal mineral retention. A large package of roots also provides a lot of effective organic matter. So base your choice of green manure not only on the above-ground, but also on the underground development!
