How much 33-0-0 Nitrate should I use on my sweet corn per 100 ft of row? My rows are pretty big, so I would say the corn is at least 2 feet apart from row to row. That said should I plant at the bottom of the rows, or closer to the plants? Thanks.

Is the 33-0-0 the NPK of the fertiliser? If so I would use a more balanced fertiliser 12-15N, 3-6P, 8-15K. Grow your corn to about 1.5 feet and then run a handfull down each side covering about 4-5' with each handfull. Then hill the soil up around the plants - new roots will grow and help stabilise the plants. If you want to fertilise before planting don't use 33N - it will burn the roots of new germinating plants. Spread the fertiliser over about 1' of the row width and rake/dig it into the soil before planting seeds.
