I was careful to hold it downwind and wore a mask most of the time. I would drop a pill in in the hole and cover with my foot. It helped but I couldn't get them all. [Reply]   [No Email]

If we had to change a valve or aything like that we had to drain them down to no pressure. That was a good way to utilize the otherwise wasted product. Just got back from giving a presentation on in season testing. I went over PPNT, PSNT, Tissue testing, and SCN testing. Fun times! Any ideas on research I should do on soil sampling and getting quality results? [Reply]  [No Email]

Sounds like you already know how to soil sample. Tissue testing is more complicated, something I have not done. Also the abbreviations PPNT, PSNT and SCN I am not familiar with. Been retired since 2001, your answer may or may not register in my head -- Who do you work for? I was a research agronomist for Kansas State University for 29 years at Garden City, KS. Tractor hobby is a return to my early years to keep me from becoming nuts. [Reply]  [No Email]
