Any Row Crop farmers....

Hey guys, i already have the wheat and turnips planted and have been pulling em and giving them to the less fortunate by advertising on the tradio shows. I eat em myself. The deer are working them over big time. That plot is proably 1/2 acre. Flatlander, good info but let's get more specific if you have time. The Glyphos, whos the manufacturer? I like the sound of cheap but still needs to be effective. The planter i have purchased for $150 is in great shape but old. It was a horse drawn unit but has been converted to 3 point hook up. That being said the horse drawn rigs were as wide as a mules *** for that very reason. 40" between the rows but i thought i could double run and do em 20" apart if that isn't too close. Next, what is N/P/K ? So the corn, milo, and soybeeans take different spray? What for each? I plan to put in several rows of corn(40) 20" apart, the step over and do the same on the milo, then step over and do several rows of beans. The critters may eat em off to the ground before they ever get a chance to grow. I am planning about 3 of these patches 100' wide x 400-600 feet long. How does one determine how much seed to be needed. We guaged my planter and it will drop a seed every 10". Maybe i can post a pic of the planter. One of the patches will be sweet corn and crowder peas for guys like me that like good food. I'll be feeding the less fortunate also if some folks are hungry. Give me a name of the pre emerge for the corn. On the soybeans, what do you mean "If round up ready"? It looks as though i'll need to buy or rent a boom sprayer to do it right. I called on one yesterday and this guy has a 100 gal unit with 3 sections of booms and it's a bout 4 years old for $600. That's really more than i'd like to part with but i may if i cant find a good buddy with one. Please let me know on the other issues . Hey 30, the grass on the location now is fescue and i really think it needs to be killed out. Very stuborn and it clumps up. Not as bad as bermuda but the quail dont like dealing with it. I'm gona try and kill it out. Good for cattle but fescue has got the blame for the decline in our quail population around here as the cattle took preference. Thanks a bunch
