I am strictly a commercial fertilizer guy. I custom mix Calcium Nitrate (15.4-0-0), with 16-16-16, and with Ammonium Sulfate (21-0-24-4.5). I use a ratio that conforms with the recommendations made by the University of Kentucky website for tobacco growing. This year I added a small amount of Boron, and I add small amounts of Iron and copper in a single application. Additionally, I split my fertilizer applications into three parts. I add said fertilizer three times throughout the growing season. I fertilize at planting, and two more times at approximately 30 day intervals. I shun all forms of Urea based nitrogen fertilizers. I spent part of my earlier life in the commercial fertilizer / pesticide business, and learned a whole lot about soil fertility. The company I worked for at the time sold commercial fertilizer by the thousands of tons per year.
It also helps that I have very high quality dirt. The soils around here will yield 140 bushel wheat on dry land farms (no irrigation). It also helps that I have a Bachelor of Science degree in Agriculture from a Land Grant University. I also know a great deal about rocks, minerals, and Mineralogy which also helps. Hopefully, my run-on sentences will translate into Italian reasonably well.

My Ternopolskii 7 seed is from a commercial source.
Is Delhi 34 supposed to be so small? Mine are 3 - 4 feet and pretty puny. There won't be a whole lot of leaf there.
