“…Optimal management depends on understanding the beneficial effects of certain practices and how they interact with other factors. Corak et al ( 1991 ) present results demonstrating improved corn yields where hairy vetch is used as a winter legume cover crop with no additional nitrogen added. Transpiration by vetch at the time of corn planting reduces the water content of the soil profile.…”

Soil erosion is increasingly a multidisciplinary affair. Understanding the processes of erosion and assessing the status of land degradation remain priority areas for physical geographers, but national and global attention towards the broader issues of resource conservation and sustainability has widened the perspective of research on soil erosion and soil problems and the range of disciplines interested in these problems. The integrity of soil resources for future production can only be assured by sustainable land use, an intuitively simple concept but elusive to define and deliver. Enquiry concerned with the nature of erosion processes, strategies for soil protection and the prevention or rehabilitation of soil pollution are important components in the quest for sustainability. Research on erosion process investigation, experimentation and modelling has continued apace (e.g., Bryan, 1990) but this review concentrates on the ethos of sustainability and progress towards protecting soils from degradation and pollution.

“…Possible explanations for the non-nitrogen associated yield increase under enhanced rotation include fewer pest problems [117], improved plant nutrition [118], increased root activity [119], altered mycorrhizal populations [120] improved precipitation use efficiency [15] and benefits from other soil property enhancements such as improved infiltration, increased mulch cover, and soil moisture conservation [26,86,99,104,121,122]. Some of those changes may be connected to the benefits of higher soil organic matter levels from red clover, direct biomass contribution and more indirect synergistic "rotational effects" on soil structural properties.…”

Improving Resilience of Northern Field Crop Systems Using Inter-Seeded Red Clover: A Review

et al. 2013

Abstract:In light of the environmental challenges ahead, resilience of the most abundant field crop production systems must be improved to guarantee yield stability with more efficient use of nitrogen inputs, soil and water resources. Along with genetic and agronomic innovations, diversification of northern agro-ecosystems using inter-seeded legumes provides further opportunities to improve land management practices that sustain crop yields and their resilience to biotic and abiotic stresses. Benefits of legume cover crops have been known for decades and red clover (Trifolium pratense) is one of the most common and beneficial when frost-seeded under winter wheat in advance of maize in a rotation. However, its use has been declining mostly due to the use of synthetic fertilizers and herbicides, concerns over competition with the main crop and the inability to fully capture red clover benefits due to difficulties in the persistence of uniform stands. In this manuscript, we first review the environmental, agronomic, rotational and economical benefits associated with inter-seeded red clover. Red clover adaptation to a wide array of common wheat-based rotations, its potential to mitigate the effects of land degradation in a changing climate and its integration into sustainable food production systems are discussed. We then identify areas of research with significant potential to impact cropping system profitability and sustainability.

“…Cover crops are short-lived species that are seeded with the main crop to assist in its establishment (Hartwig and Ammon 2002). Cover crops decrease water runoff and soil erosion (Hartwig 1988), add organic material to the soil (Hartwig and Ammon 2002), and sequester N (Corak et al 1991). Cover crops have been used primarily in cropping systems (Hartwig and Ammon 2002), but their benefits may be similar during restoration of invasive plant-infested rangelands.…”

Land managers typically use herbicides, biological controls, fire, grazing, and revegetation to manage and restore rangeland dominated by invasive plants. Without careful planning and implementation, these tools may temporarily control the weeds but may ultimately have minimal influence on ecological processes, fail over the long term, and lead to weed reinvasion. This can result from the lack of a broad ecological perspective. Successional management provides a process-based framework for weed ecologists to develop and test integrated weed management strategies and for land managers to organize implementation of these strategies in a way that adequately addresses ecological processes. This framework offers land managers practical methods for modifying ecological processes to direct plant community composition away from invasive species and toward desired plant assemblages. To date, successional management has not gained widespread application because, in part, it has not been conceptually linked to other successional models. Therefore, we illustrate how other successional models can be incorporated within the framework. Incorporating other prevailing successional models will further elucidate ecological processes, offer additional management strategies, and widen the possibilities for ecologically based management of rangeland weeds. Approaching management of weed-infested rangeland through this process-based framework will enable managers to implement strategies that maximize the likelihood of success because these methods will be integrated based on ecological principles. Successional management should be adjusted as we gain a better understanding of the factors that drive succession.
