With this smart calculation tool, determining the optimal setting values for the current 12 volt spreaders from LEHNER is child's play. No matter if you want to spread slug pellets, catch crops, grasses, seed mixtures, road salt or other granulated materials with your LEHNER spreader. You simply select the respective spreader in the app and can then decide between the value determination via spreading material calculator or spreading material selection. Then enter the desired parameters, such as application rate, working width and speed, and you will immediately be shown the necessary setting values for your LEHNER spreader. Of course, you can also add this overview directly to your favorites and call it up again in the future without having to enter/calculate it again. The LEHNER spreading app is available in two languages - German and English.

Soil structure is an essential component of soil fertility. The spade diagnosis is a suitable method for assessing the soil structure and other attributes of soil quality from observations such as odour, colour, roots, soil particles or soil layers. The SoilDoc app guides you through the spade diagnosis and the observations for a complete assessment of a selected soil. The app can replace former printed instructions. The SoilDoc app asks questions about the soil, which can be answered with a simple click. Additional information and example pictures help to find the answers. During the evaluation, the app collects all observations made and generates a report. The report is stored on the mobile phone and can then be exported in csv, txt or html format and saved as a PDF file on a computer. The simple archiving of the observations facilitates the comparison of different surveys at the same location.
