The BIO mulch roller ECO-ROLL is the alternative to mulching. The roller can be entrained without any problems during any operation. The ECO-ROLL compresses the vegetation, whereupon the spades mounted on the roller kink the stalks and thus fold them over. The result is a mulch carpet that promotes good shadow fermentation. The plants sprout again at the vegetation point and provide the next organic carpet. With legumes, this method stimulates the growth of the nodule bacteria (rhizobia) and increases the nitrogen-collecting effect.
