Managing the continuous corn yield penalty with crop and residue management
… to the CCYP are soil nitrogen availability, residue accumulation, and the weather. Therefore, the objective of this research was to evaluate and determine management practices that could help relieve the yield penalty associated with production of continuous corn compared to when rotated with …

Goss’s wilt and leaf blight of corn: chemical control, residue management and resistance
… of Goss’s wilt, including chemical control, residue management and the use of resistant hybrids. These three areas of control were the subject of this research. While there are resistant hybrids for some regions, the availability of resistant hybrids may be limited for other regions. In areas …

Broad-scale Assessment of Crop Residue Management Using Multi-temporal Remote Sensing Imagery
… tillage. Alternatively, conservation tillage management can mitigate adverse environmental impacts of tillage, such as soil and water degradation. Adoption of conservation tillage has continued to increase since its first introduction, which raises questions of when and where it is practiced. …

Feeding the soil to feed the planet: soil health outcomes from novel amendments to residue management
… mitigated through the sustainable and innovative management of soils. Specifically, the application of organic inputs including composts and animal manures can help enhance water holding capacity, organic matter accumulation and crop production. However, the heterogeneous nature of soils and …

Crop residue management effects on crop production, greenhouse gases emissions, and soil quality in the Mid-Atlantic USA
… stover and wheat straw (Triticum aestivum L.) residues have particular promise given these crops are widely grown and their cellulosic fractions present a captured resource as a co-product of grain production. Annual systems also offer the ability to change crops rapidly in response to changing …

Effect of Alternative Management Practices and the Fungal Endophyte (Epichloë festucae var. lolii) on Improving the Longevity of Perennial Ryegrass (Lolium perenne L.) in Minnesota
… The first research project explored alternative management options, including fall residue management strategies and plant growth regulator applications, for multi-year seed production of perennial ryegrass. Our findings suggest that fall residue management, including both field burning and …

Cover Cropping on the Canadian Prairies: A Mixed Methods Study to Gain Understanding of Cover Crop Agronomic Practices Among Farmers
… Common challenges are found with fertility and residue management, CC stand establishment, and crop rotations. Farmers have built confidence in the benefits of CC through improved water retention, reduced soil erosion, reductions in cash crop inputs, and additional grazing opportunities. A new …

Evaluating the interactions of crop management, carbon cycling, and climate using Earth system modeling and remote sensing
Crop management practices, such as soil tillage and crop residue management, are land management activities with potentially large impacts on carbon (C) cycling and climate at the global scale. Improvements in crop management practices, such as conservation tillage or 'no-till' (NT), have been …

Strip-Tillage Production Systems for Tobacco
… labeled for tobacco. This research investigated management practices to address slow early season growth characteristic of strip-tillage tobacco production. Objectives of the first study were to evaluate the methods of starter fertilizer application and determine the optimal rate. A transplant …

A Case-Based Reasoner for Evaluating Crop Rotations in Whole-Farm Planning
… system include: a crop rotation, its tillage and residue management practices, and field conditions. Soil erosion risk is quantified using the C-value. Pest risks are likelihood of pest outbreaks that require control in a crop rotation. CBR was the chosen methodology for system implementation. In …

Variabilité de la respiration hétérotrophe du sol dans des écosystèmes agricoles: Analyse à différentes échelles spatiales et temporelles.
… taken from a limed agricultural field. Crop residue management (in both quantity and quality), as characterized by relatively low input levels in our experiment, influenced soil carbon stocks in the long term. However, HR, microbial biomass, labile carbon and metabolic diversity were not …

Evaluation of management practices and remediation techniques for improving water quality in agricultural systems
… In this study, the effects of three sugarcane residue management techniques, namely burning (BR), shredding (SR), and retention (RR) of residues on: surface water quality, carbon export, and chemical composition of organic matter in the runoff sediments were characterized. Separate studies were …

Long-term Residue and Water Management Effects on Soil Respiration and Soil Aggregate Stability in a Wheat-soybean, Double-crop System in Eastern Arkansas
… organic matter through sustainable agricultural management practices can both remove atmospheric C and improve soil quality. The objective of this study was to evaluate the long-term effects of water management (irrigation and dryland), residue management [burn and no-burn, conventional (CT) and …

Legume integration and nutrient management impacts on soil health and cropping system productivity
… farming systems globally. Thus, proper management of soil is critical for supporting long-term crop production and addressing multiple sustainability challenges in these agricultural systems. Integration of legumes into cropping systems, especially when combined with organic nutrient …

Ecological assessments of Pseudomonas communities in pastoral soils: implications for disease suppression and sustainable production in agricultural grasslands
… are antagonistic against selected pathogens. Management of the diverse soil microbial communities towards a disease suppressive microbiome is an emerging approach to plant disease control in agricultural systems. In comparison to arable systems however, disease suppression under pastoral …

Epidemiological studies and sustainable approaches for the control of strawberry powdery mildew
… and offers limited support for effective disease management. The first objectives of the thesis were (i) to revise existing literature and (ii) assess growers’ challenges to identify current research gaps and practical constraints in the field. After analyzing the extensive literature, major gaps …

Psychological insights for sustainable agricultural transformation
… Specifically, the widespread practice of Crop Residue Burning (CRB), involving the open burning of crop residues to clear fields after harvest, contributes 3.5% to global emissions. In Thailand, with the majority being smallholders, farmers are under pressure to reduce emissions from their …
