How Much N Does Your Maize Crop Really Need?
Over the past few weeks, I’ve had several conversations about nitrogen (N) management in maize crops for the coming planting season.
In the early days the crop needed to be cut extremely short to ensure all the kernels were cracked and digestible, then the corn cracker systems of the late 1980s allowed an increase in crop length, while achieving the same result.
A silver medal will go to Claas at Agritechnica in Germany in mid November for its recently launched MCC Max maize silage conditioning system for its Jaguar range of self-propelled forage harvesters.
Using a pair of rollers with a saw tooth profile and 30 angular segments, the system combines friction, cutting and shearing to intensively condition the grains and release the maximum amount of digestible starches (which increase energy levels), as well as shredding the stalk material at chop lengths up to 22mm.
This can increase feed value, and there advantages in the ensiling process, not least by achieving better levels of consolidation at longer chop lengths.
Surplus maize silage could find buyers in the burgeoning AD gas production industry from a common silage clamp.
