2024-08-26 00:00:00 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.
