Gardening device for soil cultivation and method for sowing or planting with the gardening device

A gardening device for soil cultivation, comprising a handle section, a ground contact section attached thereto, for example a blade, a power supply, a number of detection devices for detecting a number of variables corresponding to soil properties, a computing unit for calculating the soil properties from the number of variables corresponding to the soil properties, and an output device for outputting the soil properties and/or soil properties based information, wherein the ground contact section carries electrodes, via which the number of the variables corresponding to the soil properties are detected, and wherein one of the number of detection devices is a nutrient detection device for detecting a number of variables corresponding to the nutrient content in the soil, and the computing unit is designed for calculating the nutrient content in the soil from the number of variables corresponding to the nutrient content in the soil and the output device for outputting the nutrient content in the soil, wherein the ground contact section is made of fiber-reinforced plastic such as glass-fiber-reinforced plastic, and the nutrient detection device detects an electrical conductivity of the soil as a measure of the nutrient content and comprises at least two of the electrodes for conductivity detection, which are mounted spaced apart on the ground contact section, wherein these conductivity measuring electrodes comprise or consist of a layer deposited as electroless nickel on the ground contact section.
