The long-term productivity of forest ecosystems depends on the cycling of nutrients. The effect of carbon dioxide fertilization on forest productivity may ultimately be limited by the rate of nutrient cycling. Contemporary and future disturbances such as climatic warming, N-deposition, deforestation, short rotation sylviculture, fire (both wild and controlled), and the invasion of exotic species all place strains on the integrity of ecosystem nutrient cycling. Global differences in climate, soils, and species make it difficult to extrapolate even a single important study worldwide. Despite advances in the understanding of nutrient cycling and carbon production in forests, many questions remain. The chapters in this volume reflect many contemporary research priorities. The thirteen studies in this volume are arranged in the following subject groups: • N and P resorption from foliage worldwide, along chronosequences and along elevation gradients; • Litter production and decomposition; • N and P stoichiometry as affected by N deposition, geographic gradients, species changes, and ecosystem restoration; • Effects of N and P addition on understory biomass, litter, and soil; • Effects of burning on soil nutrients; • Effects of N addition on soil fauna.

Consumers in the EU and beyond are increasingly concerned about the impact of pesticides on the environment and human health. In the context of EU phytosanitary and environmental policies, the common EU challenge is to reduce dependence on chemicals, improve food quality and increase the potential for developing more bio-based production systems. Therefore, novel control methods and new strategies that reduce the current dependence on insecticides need to be developed, applied and disseminated among stakeholders. As a cornerstone of sustainable agriculture, integrated pest management (IPM) aims to improve farmers' practices to achieve higher profits while improving environmental quality. Implementing the principles of IPM in agricultural production requires new and up-to-date knowledge generated by science and accepted by farmers. In this Special Issue, we focus on recent advances and methods for IPM in field crops. It contains eight original research articles and two review articles dealing with different aspects of IPM in some of the major field crops: Potato, Maize, Soybean, Sugar Beet, Barley, Rice, Eggplant and Quinoa as well as farmer education issues on IPM. The studies published refer to all the basic principles of IPM and give examples of their implementation in different crops and cropping systems. Research on various aspects of the implementation of IPM in crop production is a continuous need. The research presented helps to provide a mosaic picture with examples of how crop-specific, site-specific and knowledge-intensive IPM practices should be considered and translated into workable practices.
