Yield mapping. Greater transparency.
Any production process ends with an assessment of its success. This is particularly true in crop production. It is essential to document the quantities harvested so that you can find out whether the treatments applied over the course of the year have been successful and achieved their objectives. Yield measurement and mapping is another way of recording the various characteristics of a field, making it easier to plan future seed and fertiliser strategies.
Sensors on the combine harvester record the yield and grain moisture by measuring the amount of grain, the distance travelled and specified working width. A yield value is recorded every one to two seconds. Geographic coordinates can be added to the yield measurement points by linking the yield measurement to accurately corrected GPS signals (georeferencing). Yield mapping provides a complete picture of the real spatial yield potential for the whole field.
Using TELEMATICS or a memory card, the data can be imported from the machine into any ISO-compatible farm management software such as AGROCOM NET or 365FarmNet, where it serves as a basis for precision farming. Yield maps created in the software quickly reveal yield variations within a field and make it possible to locate potential problem areas. These maps can then be used to plan site-specific management measures and to monitor changes by making comparisons in subsequent years. The yield potential of different crops can be compared by defining yield zones. Comprehensive potential maps and forecasting trends can be developed on the basis of several years of data.
Benefits:
- Geolocation of "weak points" so that the cause can be investigated
- Identification of differentiated sampling areas
- Direct information about nutrient removal by considering the yield in relation to the basic fertiliser application
Yield potential maps. Influence of terrain on yield.
Low-lying areas and hilltops have a significant impact on yield. These zones can be reliably identified by means of an elevation model. The potential soil moisture map can be used as a basis for seeding and fertiliser maps and for the yield potential map (CROP SENSOR).
- Reliable data quality thanks to extremely accurate elevation data
- High- and low-yield zones are displayed with water-limiting growth conditions
- Low-cost additional information for successful, precise crop production
