More than likely it was too much. How tall was the corn when you applied the compost? Compost worked into the soil before planting is OK, but then don't add any more till the corn plant is 2, 3, or 4 inches tall. The taller the plant, the easier it is to put the compost down without covering the crop plant. But you don't get the benefits as soon either.It was grass clipping compost. I was particular about avoiding weed killer treated grass.. Pretty dense from last year. Perhaps I put it on too heavy?
We used to use wheat straw around the vining plants (melons, cucumbers, sweet potatoes, pumpkins, etc.). I admit, the pumpkins were pretty good about covering the ground and attacking weeds all on their own.
