10-10-10 has ten pounds each of NPK per hundred lbs from the bag. An organic fertilizer, such as a manure with a 2-2-1 content will have two pounds of N per 100 pounds, two pounds of Phosphorus, and 1 pound of Potassium per hundred pounds of material applied.
If you have 100 feet of row, then figure you will need a three foot wide strip for growing it, considering the root spread..... thus you will have three hundred square feet of area to fertilize. Most recommendations for garden use a lbs per 1000sq. feet---and you have one third of that area.
Here is a pretty good publication showing that sweet corn needs about 4 to 6 lbs per 1000 sq. ft. http://extension.usu.edu/files/publi...eet/HG-510.pdf
so, you will need anywhere from 1 1/3 lbs to 2 lbs of nitrogen
---or ?????lbs of chicken manure spread in the planting area.....
BUT, here's the rub. The ???'s were inserted because, chicken manure is quite variable in the nutrient content. http://edis.ifas.ufl.edu/aa205
shows that variability, so you need to recalculate based on a more accurate measure of the actual NPK content in the various kinds--and the quality of the manure you have. Also, in most soils, unless they are severely depleted, you can almost ignore the phosphorus and potassium(your manure and soil reserves usually are enough) and concentrate on the N
So, as an example, the chart shows undercage scraped litter at 28 lbs of N /ton... That is .014 lb of N per pound of manure(or an analysis of 1.4, not 2)...You need 2 pounds N max, for your strip, so 2 divided by .014 equals 143 pounds of manure.
On the label of granular fertilizer, it says, "Guaranteed Analysis". With manures, there are no guarantees......
Hope this helps.
