Answer:
Option: Soil was made richer for growing plants, and fields could be replanted for many years.
Step-by-step explanation:
It was during the Neolithic Era when people began to practice farming. Neolithic people involve in domesticating animals like goats, dogs, sheep, cows, and pigs. Crops managed with regular manure supply. The Neolithic farmers used the dung from their herds as a slow fertiliser for crops. Manuring requires a long-term process as animal dung breaks down slowly in soil and crops benefit from its nutrients. According to researchers, farmers concentrated on manuring pulses and wheat harvests for better harvesting.
