I have sowed quite a few paddocks over the last 30 odd years in different parts of the world, although not in USA - and always with a fertiliser spinner, never a seed drill. I go heavy and like Hazmat like to cross spread if possible. It is imperative to calibrate your machine by putting say a 25lbs bag in, spread over a measured distance, verify the width of spread, weigh the seed still in the hopper and do it again if necessary. A pain to do first time, but keep a note of the seed mix used and the setting, and you will not need to do the job again. A decent wind gust in the middle of a run can push the seed all to one side of the run and leave gaps, and hopefully cross spreading counteracts this. By heavy I mean around 35lbs, maybe up to 40lbs an acre if the seed bed is not as good as I would like. 22lbs in 2000 sq ft is just ludicrous in a field situation. Most seed suppliers will recommend around 25 to 30 lbs an acre, but a lot depends on seed numbers. Tall Fescue (eg KY31) is quite heavy at close to 200,000 seeds to the pound, whilst Cocksfoot (?Orchard Grass in US?) is more like 450,000. They are similar grasses in growth habit, tillering to form clumps but not spreading by rhizomes. A good seed bed and really accurate spreading or drilling and 25lbs would give you a good stand of pasture grasses and clovers in the first season. Like other posters I prefer to spend a wee bit more on seed and get a decent take first time. When sowing a ley (pronounced LAY) the seed bed should be fine and reasonably firm. There is an old UK farming expression that the secret of a good ley is a firm bottom. If you read more into that than intended then so be it! I always run over the paddock after sowing with something flat that just rubs the surface and puts the thinnest cover on the seed. I currently use a couple of chains joined with spreader bars but a sheet of concrete reinforcing mesh or heavy weldmesh is just as good if you have it. Old McDonald.
