The top part of the block has been plowed in the fall, while the bottom part and edges have been plowed in the spring. At the beginning of the growing season, the spring-plowed area suffered greatly from drought, while the fall-plowed area was already growing. However, the rains in June slightly turned the situation around. The spring-plowed area has received sufficient moisture from the rain, while the fall-plowed area has suffered from excessive water.
