The manure is brought to the wide-span boom flow rate controller by an irrigation pipe system. The manure can be applied between row crops such as corn (36 of them) long after the growing season has started; operation which is difficult to do with conventional manure spreaders. As the manure is spread at ground level with between vegetation little odour and nutrient emissions occur. No compaction problem is associated with this system as heavy spreader traffic is eliminated. As this system is a prototype, no long-term trials have been done with it and no results are provided to compare such system with conventional one regarding overall crop yields, labor time and overall costs per cubic meter or L of spread manure. This system has the advantage to broader the application period as less damages will be done during spring wet conditions and spreading can be done later in the growing season.
More work has to be done to integrate such system on farms. It seems to be a technology more appropriate for large production units or manure spreading contractors where large volume of manure has to be applied on relatively flat fields.
