It would be nice if non-farmers could understand that. Manure is great but it can't be applied with the seed when planting. Instead, it has to be spread all over the soil surface where it feeds anything growing in every square inch of the field. Until it's plowed under, it's subject to run-off. (Don't say to plow it under right away because "right away" is every day for production on many farms.) Can't be knifed in at planting as a liquid due to the salts and ammonia toxicity. Dry fertilizer, dropped with the seed, is the most efficient means of supplying NPK to row crops. Must be working if yields are increasing just about every year nationwide. Besides, where would we find all the acreage to produce that manure? 100 years ago, 22% of all workland was just to produce hay for horses. Another 3% was for mules and ponies working in mines. Can't return to that.
