Field service employee Christiaan Maljaars draws up plans for arable crops and green manures together with Van Iperen customers. Mid-October is a great time to see how the green manures are performing.
Legume green manures fix nitrogen in late summer and autumn and carry it over the winter into the next growing season. A large number of incarnate clover has grown at arable farmer Jan Mesu. The active nitrogen nodules of the rhizobium bacteria are visible on the roots of the incarnate trefoil. Image: Jorg TönjesJan Mesu from Oudelande sowed the incarnate clover after grain and before potato cultivation. This clover appears to be sensitive to mildew. However, the production of green mass is excellent. Image: Jorg TönjesJan Boonman, arable farmer in Oudelande, sowed NKG Trio as a green manure. This mixture contains facelia, field bean and flax. “Facelia is sensitive to structure,” says Christiaan Maljaars of Van Iperen. “You can see the differences in prefruits in three parts of the plot. Because the structure was good, the green manure was a success.” Image: Jorg TönjesThe flax plants fit well in the mixture, says Maljaars. They are sensitive to frost and snails do not like them. Image: Jorg TönjesThe sensitivity of the facelia to structure is reflected in the spores in the NKG Trio green manure plot. Image: Jorg TönjesChristiaan Maljaars shows the dense mat that the facelia makes on the fine soil. Facelia intensively roots the topsoil, the field beans in the mix fix nitrogen and the flax contributes to the structure.

This mix called Nfixx was already sown at the end of July and that is why the sunflowers have been blooming profusely here for weeks. Plots sown later are not as colorful, but are successful as green manure. Image: Jorg TönjesThe mix in Hoedekenskerke contains six types of legumes to fix nitrogen and other species to produce organic matter and make the soil airy. The sunflowers here are nicely turned towards the road, so that the field looks very nice to passers-by. Image: Jorg TönjesThe sorghum in the foreground has a strong root, which makes the soil more airy. The feed pea behind it (click in the middle of the photo to see it clearly) blooms beautifully purple. Image: Jorg TönjesChristiaan Maljaars thinks Krijn Leendertse’s plot is an example of a very successful green manure. The mixture is versatile, beautifully developed and exceptionally beautiful.
