Soil is a limited resource and its health is critical for any sustainable development. In areas where soils are poor due to their geological history, poor in content of organic matter or frequently affected by drought, agricultural productivity may be low.
Moreover, past and present anthropogenic activities have resulted in degradation and contamination of agricultural soils. Given the large areas of land which can be considered degraded, a huge opportunity in developing and implementing practices aimed at restoring the production potential exists.
Such a restoration could be a major contribution to open up for increased production of food, bioenergy and other ecosystem services from agricultural land. Yields from such areas would likely bring around 10 million tons grains onto the market.
Field experiments were the project core and performed by each partner. Fertility and productivity of soils were enhanced by various amendments (manure, biochar and compost pellets). Yield and growth characteristics were recorded by remote and proximal sensing. Data will be used in the final analysis to implement models. Soil organisms were analyzed based on the functionality of microbial groups, to unravel key processes responsible for soil fertility and resilience.
Models are developed to show the economic impact of ecosystem services from farming by soils, with examples from Spain, Germany, Poland and Norway. Guidelines for the treatment of contaminated soils were developed and published. The beneficial influence of soil amendments for reducing contaminant exposure and/or promoting crop yield and plant performance was revealed. Increasing yield of 20 % is possible.
Several papers are published related to INTENSE, but results from field studies and greenhouse experiments will be published during the spring of 2019.
