Project Title

Site-specific application of mycorrhizae in maize and potatoes

Project description

The project Precision-AMF project contributes to sustainable, resource-efficient and efficient nutrient management in conventional and organic agriculture. The planned development can help to reduce the pollution of groundwater and surface water with mineral fertilizers. Motivation is the interest (and necessity) of agricultural practice to target plant-strengthening mycorrhizal fungi where soil structure is particularly requiring such plant biostimulants. Arbuscular mycorrhizal fungi (AMF) are the most widespread symbiosis between fungi and plants - 90% of all plant species use the support of fungi, especially in stress situations. The goal is to use GPS-controlled sensor technology (soil structure analysis) to develop a process that enables the site-specific application. New mycorrhiza formulations adapted to soil type are being developed. In difficult field sections, soil life, plant health and nutrient uptake is systematically and sustainably improved, thus ensuring yield stability.

Results focusing on practiceorientation

The application of mycorrhiza with the corn seed showed a significantly higher frequency of mycorrhization in the root system (F%) compared to the control as well as the variant 'carrier material'. Under the Bioland Association guidelines, higher root colonization levels were observed in the untreated controls. The low crude protein and nXP contents were due to systemic nitrogen deficiency. For the field trial with potatoes in the conventional system, only very low colonization levels could be detected. No significant differences in yield could be measured due to the almost non-existent colonization. Which factor was decisive for this could not be clarified. Possible factors are the nutrient content in the soil or applied plant protection products. The result in the potato trial contrasts with the previous results of the Institute of Crop Science; in previous trials, potatoes achieved good root colonization levels. Furthermore, a method was successfully...(see final report).
