Nitrogen
Nitrogen is the main building block of all crop tissues and is required in large quantities to make growth and development happen. We always recommend that normal NPK soil programmes are maintained but with complimentary foliar applications of products containing N, P or K in some crops under certain conditions - see the NPK nutrient page or NPK option in each crop page for details. We offer 'Foliar Feed' which has 200 g/kg N which can give all crops a boost particularly during times of stress.
