Addressing the practical problems encountered by farmers applying 
new technologies (e.g. fertigation).

Recent focus on fertigated vegetable crops include studies of:
The crop response to NO3 concentration in the irrigation water 
Effects of N on the quality of the product
Vegetable growth rates and  leaf analysis
Increasing the efficiency of fertigation by studying parameters like time, concentration and placement of N application through the drip system, in order to reduce NO3 leaching and increase crop N uptake.

These studies are presently being extended to include denitrification, N mineralisation and the effects of residual N in fertigated vegetable crops.

Interests:
Aspects of soil management and the evaluation of nutrient requirement 
and balance. 
Long term research on: 
The effects of tillage on yields and soil quality, 
Irrigation scheduling and interactions with nutrient use, 
Fertilizer strategy and the development of new recommendation systems
The assessment of crop residue effects on subsequent crops. 

Projects: 
Nutrient management in organic vegetable growing. 
Current trials are aimed mainly at assessing means of supplying nitrogen to crops in the absence of farmyard manure, which is often not available in sufficient quantities in the arable regions of Norway. The use of legume crops, either incorporated as green manure, interspersed with the growing crop (living mulch) or applied as a surface mulch in the growing season, is being investigated in cabbage and root crops.
