Abstract: It is well known that soil preparation plays a key role for optimization of the crop. It is less known that some fertilizer reach a plant root system below 20 cm after two or more years if applied at the soil surface. Also a large portion of the fertilizer never reaches the plant roots. As a consequence the large amount of the fertilizer is lost due to over dosage is used. In addition the excess fertilizer merges into undesired environment like ground water, plant leaves etc. and is spread by flies, bees and other bugs and finally end up in animal nutrients or human food. The solution to the problem is to provide the fertilizer under the ground level close to the plant root system, with the right composition of the nutrients and with the right quantity. In the paper we are presenting an agricultural machine capable to penetrate underground about 30 cm with vibrating tools and with the automatic dosage of different required fertilizers. The remaining problem is how to analyze the soil on the fly to determine which nutrients are missing and how much is needed to fulfill the optimal calculated fertilization plan. In the paper the soil characterization methods are briefly discussed and the results of the proposed soil electrical impedance frequency specter are presented and discussed 1.

 

Keywords: Soil classification, Soil impedance spectroscopy, Real-time soil sensor.
