“Your Point of Diminishing Returns”

Every first-year Ag class includes an explanation of “The Law of Diminishing Returns” and while we may agree with the concept on an intellectual level, it’s easy to “Do the same as last year” or fall into the “If a little does a little good; A lot will do a lot of good” way of thinking.  With regard to the bottom line, both of those options can be expensive whether you apply too little or too much.

Purdue University recently released the results of an eight year study on nitrogen management.  AgLoop recommends you read it:

Also, check out the N-Rate Calculator developed by Iowa State University:

Who knows, a few minutes may save you some money and make a smaller foot print on the environment at the same time!
