A long-term study looked at how different ways of farming affect soil quality. They tested various methods like ploughing and not ploughing, and how straw is managed. The study found that less intense ploughing made the soil harder and stronger. Spreading straw on the field didn't have a big impact. Mixing plant residues into the soil before planting improved soil structure. Overall, less intense ploughing and incorporating plant residues into the soil can help make the soil healthier.
