Farms: Tight Nitrogen Farm

High productivity with a low impact

The Super P and Tight N farms ceased operating  on 31st May and 28th August 2009 respectively.

A report of the 3 years of farmlet operation is being prepared and will be available on this website shortly.

Preparation is underway to replace the farmlets with new ones from March 2010.

Aim: Produce 1200 kg MS per ha with no brought in feed and reduce Nitrate leaching to less than 25kg N per ha, which is 50% of measured levels in the Control farmlet.
Size: 7 ha
Herd: 21 cows
