The meteogram Soil Trafficability shows the capacity of the soil to support moving vehicles based on the soil type and the development of water content in the topsoil (0-10cm). The development of Soil Trafficability is represented in a line graph (black) that moves though 3 trafficability conditions, good trafficability (green), restricted trafficability (yellow) and no trafficability (red). The meteogram shows the development of soil trafficability for four types of soil: Sand, Silty Loam, Silt and Clay, each of which has a different water holding capacity and reacts differently to weather conditions.
The calculation uses information of precipitation amount, sunshine hours, soil-specific water holding capacity and more from the past season, as well as the 7-day forecast.
The current conditions in fields may change significantly depending on spatial differences, type of soil cultivation, land cover, plant growth, irrigation and other factors. The presentation of the soil trafficability shows foremost the differences in the timely changes on different soils and thus helps in the planning of field work, especially during critical work phases such as soil preparation, crop protection treatments and harvesting, as well as for purposes of construction.
