Has there been any studies done on comparing the differences between the drilled-to-15"-split-row and 30" row systems in production cost, machinery maintenance costs, etc?
I would like to know if there is a recommended tire pressure (in psi please) for 4 WD and MFWD tractors that might help reduce compaction?
What do you feel would be the best type of tires to put on to our 4wd tractor?

Does no-till drilled soybeans yield better than row beans?
I am interested in switching from ridge till to no till. Can you give me any tips on techniques and equipment that I need?
I once heard a professor explain how atterberg limits can be used to time tillage operations so that compaction can be reduced. If so, how does one go about assessing soil moisture suitability for tillage?
I would like to know the disadvantages of no-till farming.
Where can I find a guide to soil types and their abilities to accomodate conservation tillage systems ?
