SOILAssist: Sustainable protection and improvement of soil functions with intelligent land management strategies – a practical on the fly assistance system for farmers

SoilAssist is an interdisciplinary research project with the aim of holistic observation of agricultural soil protection during the survey of arable land and to recognize and avoid negative changes in soil structure and functionality at an early stage, as well as to maintain and improve it by means of adapted management. The Thünen Institute for Agricultural Technology is responsible for the coordination of the joint project, the development of the soil model and, in cooperation with the project partners, the development of the real-time assistance system. The Climate and Soil Departments are responsible for the subprojects "Socio-economic analyzes" and "Acceptance and knowledge transfer". The joint project SOILAssist is part of the funding measure BONARES of the Federal Ministry of Education and Research.

In September 2019, after the successful completion of the first phase, the second funding phase of three years began. In the coming years, the work from the first phase will be continued or new work packages will be built on the results of the first phase. Detailed results from the first phase can be found on the SOILAssist homepage.

Background and Objective

In the last years and decades the sizes and total weights of agricultural machinery increased more and more. This was primarily for economic and process-efficiency reasons. High specialized machinery requires high operating grades. In adverse conditions, considerable negative changes in soil structure and in multiple soil functions occur. Basically soil functions are affected negatively by intensive agricultural field traffic. Management based negative changes in soil functions still have negative effects on economic and ecological efforts and benefits. For using soils as a sustainable resource for bio-economic purposes (BonaRes), agricultural land use should put a focus on sustainable protection and improvement of soil functions, while keeping the economic conditions in mind. The SOILAssist consortium will put a holistic focus on this area of conflict.

Target Group

Research community, Soil research community, farmers,agricultural contractors, agricultural extensionists, education, Policy makers

Approach

Surveys of multiple passes of agricultural machineries at various points with different soil load in the field

Route tracking of machineries on the field etc.

Multi – Sensor - System measurements (deflection, track depth, total weight, inflation pressure, contact area etc.)

Field measurements (penetration resistance, soil moisture, variation in the fields etc.)

Soil surveys (undisturbed soil cores)

Laboratory measurements (changes in soil functions)

Soil modeling (3D – soil pressure , deformation and functionality model)

Field demonstrations, thematic workshops

Questionaires for farmers

Socio-economic evaluation.

Our Research Questions

To what extend does the application of multi-sensor data from minimal and non-invasive measuring platforms enable the prediction of soil compaction effects inside of a field?

What indicators are suited to assess the changes in soil structure and soil functions caused by field traffic? Can we define threshold values for sustainable soil management?

How must optimal agricultural processing chains be designed to maintain / improve soil quality and soil functions?

Can approaches to simulating traffic-induced soil stresses and related effects on soil functions contribute to an “on-board”-assistance system to optimize field management?

What are the economic effects of sustainable field traffic and what are the costs and benefits of soil-adjusted field traffic?

Preliminary Results

To hit this targets, an ‘on the fly’- assistance system for farmers and agricultural contractors will be developed, applied and implemented to optimize the soil conserving traffic on agricultural land and to prevent negative changes in soil functions by optimizing machinery configuration, machinery routes on the field etc. and the overall management.

Additionally, recommendations and recommended actions for farmers, agricultural contractors, agricultural extensionists and political consultancy and an advisory system will be established, to support decision making of farmers for a foresighted planning of soil conserving agricultural management strategies. Moreover, the socio-economic consequences of different management options will be identified and assessed.
