We have tons of naturally occurring nitrogen in this world. Not only does it rain down on us it also is put into the soil by legumes, it is introduced to the soil by plant and root decomposition. And very little nitrogen of any kind washes into streams from surface water. Nitrogen is attracted to water that carries the nitrogen down into the soil and it does end up in shallow water tables. Here in Iowa nitrogen can get into streams when it is carried along in the water from drain tile under the fields. Several smaller rate applications of nitrogen on the crops can help with this leaching into drain tile. It will not alleviate it though. Several applications means more machinery expense per acre and more hours spent running the machinery. If we have a dry year the unused natural and man made nitrogen can stay hung up in the soil but if the next year is wet that built up nitrogen can turn into a glut of nitrogen being carried down into the water table. Then the environmentalists really get dandered up thinking this glut will happen every year where in reality it is a one year occurrence. I would think the phosphorous and potassium load on the Mississippi would be lower now that farming has gone to minimum or no till but it doesn t look that way. Potassium and phosphorus attach to the soil and stay put as long as the soil stays put. If the soil washes into the stream the P and K will ride along with the soil. Just a few random thoughts.

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
