Dry land farming in semi arid country is way different than places with rain. Here in North Dakota we average 14 inches total precipitation which includes snow. Jim said they are at 12 to 13 inches. All the fertilizer in the world does no good without water. You seed and fertilize accordingly. This dry farming does result in the best quality small grains. Guys here are still trying to get last years crops off so they can seed this years crops. About half done here. Ed k
