The implements for summer mulch cultivation

Where in spring it was the crust-breaking implements — striegel, harrow and hoe — it is in the post-harvest summer those that are to loosen the topsoil shallowly and mix it with plant residues. Depending on the depth of the crumbly tilth-layer, the cultivation depth amounts to 8 to 12 cm (Figure 13, p. 222). The diversity of implements testifies to the fact that evidently none of them fully meets all the desired requirements of mulching. The classic implement for stubble cultivation was — and could by its function still be — the skim plough: cutting fully through the sole, turning shallowly, cutting narrowly, it achieves through its shearing break-up and the crumbling-sifting deposit of good tilth a fine mixing effect. With the large working-widths demanded of skim ploughs today, and with the pressure-tracks of combine harvesters reaching in most cases right down to the sole of the tilth-layer, a clean skim-work can hardly
