If you are using organics I doubt you can overfeed corn, last time I grew corn I was using synthetics in compost amended soil and I couldn't seem to over fert that way either ;-) Your plan sounds fine to me, but why not fert a bit less with a row just to compare?

I had read that corn is fertilized twice - Once when planting/germinating, and once when tasseling. That may not apply, to organic gardening though, since organic fertilizers are weaker/timed release compared to things like Miracle Gro.

I have a similar question. I am putting another 12-inch-deep bed in, and will have corn there. I am planning to fill the bed with roughly equal amounts: composted steer manure, coffee grounds, semi-finished compost, and maybe 30% original soil (which is clay and has a high pH of about 8.)

I'm wondering if I am missing anything or overlooking something. I am also wondering if I can plant the corn closer, if I make the soil richer. How close/how rich?

Patty, I think 9" spacing is about as far as you might push it. I believe there are some Sq. Ft gardeners who have tried 6" spacing, not sure what results they got.

Your mix sounds really yummy for corn though.

You are aware though that since 70% of your mix is organic, you will get significant volume reduction over the season as the 70% organic matter decomposes? Not necesarily a problem, as long as you are planning for it.

Thanks for the replys so far.

patty4150, I do Square Foot Gardening so I will be planting one per square in a 3x3 block. Apparently the block approach helps with pollination but I'm also concerned about making the soil rich enough and supplying enough nitrogen.

try manuring at both fertilizing times
