Sustainable use of soils is among the global challenges of the twenty-first century. The global population is projected to increase to 8.6 billion by 2030 and 9.6 billion by 2050, exacerbating the biotic and abiotic impacts of climate change on global food production. This rapid population growth, coupled with food and nutritional insecurity, land degradation, declining soil fertility, and stagnant crop productivity, poses significant threats to sustainable agriculture. Current research highlights the potential of legume intercropping to address these challenges due to its multifaceted benefits, including biological nitrogen fixation, enhanced soil microbial activity, and improved soil health. However, there is a need for more comprehensive studies to fully understand and optimize the integration of legumes into diverse cropping systems to maximize these benefits.
The richness and diversity of plant species within ecosystems play pivotal roles in shaping resilience in a world marked by climate fluctuations, natural disasters, and evolving human impacts. This Research Topic delves into the intricate relationship between plant diversity and ecosystem resilience, uncovering how diverse plant communities contribute to productivity, nutrient cycling, and soil stability. These aspects collectively bolster an ecosystem's capacity to endure and recover from various disturbances. Amidst global transformations, these insights guide conservation strategies and land management paradigms aimed at preserving and rejuvenating ecosystem stability.
This book provides an authoritative summary of the role that precision agriculture plays in the production of field horticultural crops. It also shows how science and engineering redefine the place of precision agriculture in our fields, orchards and vineyards. The book provides an overview of the current state of the art, case studies of real-life applications of agri-technology in horticulture, and evidence-based perspectives on likely future developments. It addresses the challenges, limitations and potential of precision farming technologies in the production, harvesting and post-harvest sorting of a range of annual and perennial horticultural crops. The provision of fresh produce presents unique challenges and opportunities amenable to the application of agri-technology to address issues ranging from high labour costs through to food safety and traceability. Indeed, the possibilities presented by automation are catalyzing the complete redesign of some field horticultural production systems.
Weeds pose a major challenge to the sustainability of agricultural production systems, causing significant crop yield, economic and environmental losses. Chemical weed control tactics play a major role in modern weed management, maintaining the productivity of diverse cropping systems, reducing yield losses and facilitating conservation agriculture. However, the over-reliance on chemical weed control has led to shifts in weed communities in agroecosystems which are now becoming dominated by high competitors and herbicide resistance. Thus, weed scientists and practitioners are urged to develop and incorporate innovative and feasible integrated weed management (IWM) systems that can reduce weed infestations and environmental impacts.
The Neotropical area is a main setting of the earliest experiences of domestication ofplants, and evolutionary processes guided by humans, which continue being active inthe area. Studies comprised in this Research Topic show a general panorama aboutsimilarities and particularities of processes of domestication for different plant groupsand regions, some of them illustrate how the domestication processes originated anddiffused, how landscape domestication has operated and continues being practicedand others discuss some of the main challenges for designing policies for biosafetyand conservation of plant genetic resources. It is an attempt to identify main topicsfor research on evolution under domestication, and opportunities that researcherscan find in the Neotropics to understand how and why these processes occurredin the past and present.
Ecologically Based Weed Management Protect crop yields and strengthen ecosystems with this essential guide Research into weed management is an increasingly critical component of both environmental stewardship and food production. The potential cost of weed propagation can be measured in crop yield reductions, under-nourished populations, stymied economies, and more. The propagation of herbicide-resistant weed populations means that purely chemical weed management is no longer viable; food production can now be secured only with an ecological approach to weed control. Ecologically Based Weed Management details such approaches and their potential to manage weeds across a range of agricultural ...
