The frequent hard driving rains have severely compacted soils that has affected seedling emergence on many farms. The rains in some cases have caused crusting that is at least 1 inch thick in some places. The problem is accentuated in soils with low organic matter, and that have been overworked leading to a breakdown in soil structure. In the picture below, notice the short thickened stem of the pumpkin plant as it tried to push against a thick heavy crust. Methods to help eliminate the problem include increasing soil organic matter, the use of rotary hoe or finger weeders that will lightly break up the crust without disturbing the germinating seedling and the use of anti-crustants such as vermiculate in the seed row.
Notice the very thick stem.
