Next Instruments claims protein maps are the missing piece of the precision agriculture puzzle, because they provide farmers with the ability to determine the amount of nitrogen (N) that is removed from the field.
To help growers and retailers address protein mapping, the company has prepared a technical document for use called, “The Missing piece of the Precision Agriculture Puzzle.”
The company reports that N makes up 17.5% of the protein in the grains. For every ton of grain stripped, the amount of N removed is simply calculated as 0.175 multiplied by protein percent. For example, wheat with 15% protein removes 1000kg x 0.15 x 0.175 = 26.25kg of N. By combining protein maps with yield maps, Next Instruments says the following benefits can be provided:
- High density spatial data showing the variation in quality based on protein of the crop in the field
- Differential harvesting and storage based on quality
- Protein, moisture and yield maps enable creation of true site-specific gross margin maps
- N removal maps can be used to calculate fertilizer application rates
- Overlaying protein and yield maps with other data for better diagnostic insights into availability and uptake of N
- N trials and VRF applications can be measured and evaluated using real data
Along with the document, the company says the new CropScan 3000H On Combine Analyser provides protein mapping at high spatial density.
