Sovesci in orticoltura a Sud delle Alpi (Guizotia, Sorgo, Pisello invernale, Grano saraceno)


Welcome! We are here in the trial plots to test green manure varieties. It is an experiment located in Ticino, in the Magadino plain. The aim is to find the best species for green manure south of the Alps. Green manure plants suitable for horticulture south of the Alps Guizotia This is Guizotia, a very interesting asteracea, especially for the production of biomass. It has the characteristic of quickly covering the entire surface. As we can see we do not find weeds here. Being an asteracea it produces flowers that are very interesting for bees and wild pollinators. Sorghum Another species very suitable for biomass production is the Sudanese Sorghum. I really like Sorghum as a crop, as a green manure, because it grows quickly, covering the soil in an instant. Sorghum suppresses weeds and prevents their development and multiplication. On the left we see the cultivation of the Sorghum of Sudan in purity; while on the side we have mixed it with some lupine. The effect of the nitrogen released by the lupine is evident. Winter pea Another objective with green manure is the capture of nitrogen to be provided for the following crops. Here we see the winter pea that has really given good results, in fact it has been able to cover the ground very quickly and to suppress weeds. In organic horticulture a lot of attention is paid to nitrogen, because it is very expensive. For this reason, legumes such as vetch, clover, lupin and alfalfa are added to the mixtures. Bee mixture This is a special mixture for bees and pollinating insects. It consists of fifteen different species. Some are very early and therefore bloom in autumn, such as Buckwheat. Others are wintering species that will then flower in spring. Buckwheat The cultivation of Buckwheat allows to pursue several objectives at the same time: first of all to produce in a short time flowers to be used by the pollinating insects. The species has also shown a very fast growth rate and a strong ability to suppress weeds, thanks to the good production of biomass in a short time. If we were able to raise your interest, please contact us directly, or participate in the technical days, which we will organize in the coming years.
