Accurately measuring yield in grain crops
Accurate measurements of yield are important for: reviewing the success of nutrient management strategies, understanding a sites expected yield and
Accounting for crop N uptake in Soil Nitrogen Supply estimations for winter cereals
Soil Nitrogen Supply (SNS) is a measure of the nitrogen (N) available to the crop from the soil. The N
3 Step Checking – Planning
Planning is fundamental to successful crop nutrition management. It defines the quantities and timings of organic material and inorganic fertiliser
3 Step Checking – Check and Adjust
Whilst many farms create a nutrient management plan, checking its appropriateness and adjusting the plan is also necessary to avoid
3 Step Checking – Review
A review is essential to final assessment of a nutrition manager’s success and forms the basis for future improvement. Crop
Managing Phosphorus nutrition using grain P measurements
Most of a crop’s phosphorus (P) uptake (>80%) is redistributed to its grain (or tubers) by harvest. So analysis of
Managing N using grain protein as an indicator
Nitrogen (N) plays a crucial role in crop production but causes substantial economomic and environemtnal costs. Farmers must understand whether
Harvest analysis with benchmarking
Plants need nutrients primarily to support photosynthesis, and secondarily to support regeneragtion. Crop-captured nutrients are seldom lost during growth (except
Harvest analysis shows the prevelance of nutrient deficiencies
Through the Yield Enhancement Network (YEN), grain nutrient concentrations, yields and associated nutriional data have been collated for wheat and
Leaf Analysis to diagnose crop nutrient status
Essential crop nutrients (Table 1) are needed primarily to enable leaf photosynthesis, respiration and transpiration, so are initially concentrated in
