All of the confusion [in labeling fertilizer] is further complicated by the nature of the weighted N-P-K formula system. A bag might say 0-0-60. Does this mean that in a 100-pound bag there are 60 pounds of K, the rest being inert filler? Not exactly.

The fact is that farmers get a lot of things they may not even want when they buy 0-0-60,18-46-0,17-17-17, or whatever.

As an example, take ammonium nitrate—or 33.5-0-0. Here’s how they compute the formula. Ammonium nitrate of course is NH4NO3. Each of the elements in this affair has a Mendeleyeff atomic weight. N has an atomic weight of 14. O has an atomic weight of 16. There are two Ns in the formula, or 2N. There are four Hs, or 4H. There are three 0s, or 3O.

Tractor Time Episode 9: Ben Hartman and How to Make a Living on One Acre

In this week’s podcast, we’re going all the way back to last year’s Acres USA Eco-Ag Conference in Omaha, Nebraska. There, an author-farmer named Ben Hartman spoke for more than an hour about a little miracle he and his wife, Rachel Hershberger, created in southern Michigan.

In The Lean Farm, the title of his book, Ben shows how he and his family connected with local restaurants in Chicago and the southern Michigan area to create a sustainable, profitable farming venture on less than one acre of land.

His talk last year at our conference was educational, inspiring, and one worth sharing. For those who want to attend our conference in Columbus, Ohio, from Dec. 5-8 this year and talk with hundreds of farmers and experts, including last week’s guest Andre Leu, you can learn more at www.acresusa.com, or follow us on Facebook, Twitter, and of course, subscribe to our monthly magazine.
