To quantify the effects of deep ripping, gypsum application, and a new cultivation implement known as a Spader,
The penetrometer measurements show that the nil treatment at both sites had a harder soil profile in the upper 20 cm at Hannafords (clay loam) and down to 35 cm at Jacobs. The reason the Nil treatment at the site of Hannafords shows lower resistance at depth is because this zone was waterlogged (water perched on the clay layer), showing that the ripping and spading have relieved some of the waterlogging.
