The 4020 isn't done working yet! It's still good for every small chore. I decide to get ahead of the game and clean out the barnyard while I can so it doesn't have to wait until the fall.
Broadcasting manure onto the surface of a field is the oldest method of spreading. It is easy, cheap, and can be done during almost any season. But, there are also some significant disadvantages. From a nutrient standpoint, a substantial amount of nitrogen can be lost within a few days of application. This happens when ammonium (inorganic, plant available N) converts to ammonia gas, a process called volatilization. The organic N is not lost, however, and some of it may become available later in the growing season. Other concerns are odors and the possibility of nutrient or pathogen runoff in large rain or snowmelt events.
Broadcasting with incorporation means mixing, or incorporating, the manure into the soil immediately or within a few days after broadcasting. This method greatly reduces ammonia gas losses, especially if the manure is incorporated quickly. Because the manure is thoroughly mixed into the soil, it also promotes conversion of organic N into inorganic N, a process called mineralization. That means you can expect more N to be available for plant growth than when manure is left on the soil surface. One drawback is that this requires tillage, which disturbs the soil surface and may not fit in all agricultural systems. Double disk application is considered a form of broadcast application since it applied manure on the soil surface, but it is immediately incorporated as the disks throw soil on top of the manure to cover it up.

How Farms Work by Ryan Kuster is a RU-vid channel based in rural Potosi, Wisconsin. Our mission is to teach those who didn't grow up on a farm what the farming life is like. These videos show the Kuster family working together raising cattle and crops. We believe everyone who wants to know more about farming should be able to share the farming experience with us and we look to educate the world on many essential agriculture topics.
How Farms Work takes place on ~1,100 acres with around 75-200 cattle at any given time. Four John Deere tractors are currently used on the farm, which are a 4020, 4640, 7600, and 8235R.
