“…Studies on catch crops following mixed cropping of pea/cereals (Urbatzka et al 2009) and rotations of legume/rye intercropping followed by maize (KarpensteinMachan and Stuelpnagel 2000) also showed reductions in soil mineral N because of the N use by the catch or subsequent crops. Similarly, soil mineral N under pea declined with mixed cropping with cereals after harvest (Geijersstam and Mårtensson 2006).…”

Increasing crop nitrogen use efficiency while also simultaneously decreasing nitrogen accumulation in the soil would be key steps in controlling nitrogen pollution from agricultural systems. Long-term field experiments were started in 2003 to study the effects of intercropping on crop N use and soil mineral N accumulation in wheat (Triticum aestivum L. cv 2014)/maize (Zea mays L. cv Shendan16), wheat/faba bean (Vicia faba L. cv Lincan No. 5) and maize/faba bean intercropping and monocropping systems.

“…Rhizodeposition can be broadly defi ned as the release of organic and inorganic compounds from living plant roots (Gregory, 2006). Rhizodeposition of N is predicted to be higher in legumes than non-legumes because biofi xation increases their overall N assimilation rate (Urbatzka et al, 2009). Estimates of rhizodeposition rates associated with RC leys range from 5% of total plant N (Hammelehle et al, 2014) to over 100% of total plant N (Hogh-Jensen and Schjoerring, 2001).…”

Red clover cultivation made signifi cant contributions to soil fertility prior to the introduction of mineral nitrogen fertilizers. Its modern usage lies primarily in forage production, but reintegration into arable systems can enhance sustainability and preserve environmental integrity. Here we review red clovers nitrogen (N) contribution to subsequent crops, its capacity to fi x N, and how this N is transferred to subsequent crops. The senescence of the root system following cultivation also contributes to soil organic matter, providing a suite of ecosystem services which are also reviewed. Potential contributions to allelopathic weed control and how this may be utilized to improve weed control is also discussed. Red clover varieties are diverse and can be split into categories of early/late fl owering, erect/prostrate and diploid/tetraploid. This use of this diversity to diff erent ends and purposes in fertility-building and the role of plant breeding in optimizing use of genetic resources is reviewed. Management strategies are also diverse; red clover can be grown in monoculture or with companion grasses, it can be harvested for forage or green manured (which can include or omit herbicides) and the consequence of this for soil fertility is discussed. High protein forage production is also a key benefi t of red clover cultivation and the economic incentive this may provide to farmers is also reviewed.

“…A contribution of catch crops to SOM build-up can be assumed as a result of symbiotic N fixation (legumes) and/or transformation of soil mineral N that might otherwise have been leached (Urbatzka et al 2009). Both mechanisms are considered as sources for SOM build-up in the HU-MOD algorithm by lowering HD (Eq.…”

With this paper we present a simple model for the assessment of management impact in arable farming systems on soil organic matter (SOM) levels. The humus balance model (HU-MOD) is designed for application by farmers and extension workers in practice as a tool for management support. To enable practice applicability, HU-MOD bypasses the need for data on soil parameters and can be run with simple management data. HU-MOD is based on a simplified model on carbon and nitrogen pools and fluxes in the soil-plant system. The model proved to be an applicable simple tool for the comparison of management systems in arable farming with regard to the impact on SOM levels. Even though an absolute quantification of SOM level changes is not possible due to the methodical approach bypassing the need for any data on soil parameters, the model may be used to assess a positive or negative impact of a management system or management period compared to a reference and thus may be used to assess the impact of management changes, or to analyse a specific impact for different management periods on a defined spatial unit.
