There are many studies that show the benefits of compost and manure for soil, but at the rates given in the article are economically impractical (spreading alone would be about $9-10/ton so >$200/acre) and would not put the material into the soil in a no-till program. We have solved both issues and our research shows that much lower volumes show increased yields and increased soil health. A precision application through the drill at seeding has a similar effect that banding fertilizer does. At 40 lbs./acre (Compell) in no-till, dry land grain/oilseeds we are showing increased aggregation, increased nutrient uptake, and other benefits. Today we learned the WSU trials of our compost product at 40lbs/acre (about $8-10/acre cost) showed a 317lb. yield increase on winter canola.
