Sure I will do the math
100 bushel oats at $3 average last 10 years=$300-fertilizer and spray and fuel
40 bushels at $5(low end)=$200-fuel only
In your area you might make more but I compare to neighbors. Around here there are very, very few years that any conventional farmer can get over 2500 lbs an acre beans. I'm talking pinto beans.
Average bean crop here is 2200 at $0.30lbs=$660+fuel fertilizer spray
organic is 800 lbs average at $0.75-0.80=$600=fuel
Where my uncle lived in Saskatchewan where till 5 years ago rain was a commodity you wished you had,you could pour all the fertilizer on you wanted and could not get a crop. Different areas work differently. if we end up with 3-4 years of drought all that fertilizer will be dept you will never get out of unless on poor years you back off on the cost of input. We all know that God makes the rain and with out it we get ZIP,no matter how good we think we are. We see to often where the rich big farmers go bankrupt and keep farming because the gov. bails them out and they screw every person including me out of money.Sucks when the small guy sells the big guy seed and he turns around and don't pay his bills because the price of grain drops so far that if he paid ALL his bills he wouldn't make his half million or more for that year. Got real bad here when BSE. hit the cattle farmers. They went to every small guy they could and bought feed mineral and whatever from as many people and places they could charge and walked away without paying any of it. We had a string of small guys go under because the big guys wouldn't pay there bills. Us little 20-50 cow guys have hay as a side market and when you get stiffed on 200 bales of hay that hurts. The biggest feed lot in this area we hauled hay for stiffed one trucker over $50,000 That trucker still had to and did pay his fuel bill . but had to sell his cows to live on for another year. Needless to say the feedlot never blinked an eye.
