Paperback. Zustand: New. This book features five peer-reviewed reviews on biofertiliser use in agriculture.The first chapter examines the role of biofertilisers and consortia of microorganisms to improve the effectiveness of organic fertilisation, before moving on to consider the use of animal excrement, including manures, slurry and guano.The second chapter presents the key issues in the optimum use of treated wastes in crop nutrition. The chapter also discusses technical processes such as precipitation of salts, incineration and post-treatment of ashes, as well as production of carbonaceous materials.The third chapter discusses some common issues regarding the use of bio-based fertilisers, such as the concentration of nutrients leading to losses of reactive nitrogen and phosphorus into the environment.The fourth chapter addresses the key issues of arbuscular mycorrhizal fungi (AMF) and soil health, specifically focussing on improved soil structure and stability, soil contamination, carbon sequestration and nutrient retention.The final chapter provides an overview on the use of plant growth-promoting bacteria/rhizobacteria (PGPB/PGPR) and its consequent effects on plant and soil health. The chapter also explores interactions between PGPB/PGPR and other components of the rhizosphere, such as AMF.…

Paperback. Zustand: New. This book features four peer-reviewed reviews on regenerative techniques to improve soil health.The first chapter discusses some common issues regarding the use of bio-based fertilisers, such as the concentration of nutrients leading to losses of reactive nitrogen (N) and phosphorus into the environment.The second chapter provides a critical evaluation of the potential of compost to improve soil health, as well as its effect on soil nutrient cycling, soil hydraulic properties, crop productivity, soil biodiversity and environmental quality. Two case studies on the benefits and risks of using compost in perennial and annual crops are also included.The third chapter reviews the benefits of service crops, including cover and catch crops, in both intensive cropping systems and low input systems. The chapter discusses an array of studies from temperate Europe to illustrate these benefits, including the use of service crops for reducing N leaching losses.The final chapter addresses how crop rotations affect nitrogen flows in organic farming systems and how these rotations can be utilised to optimise the nitrogen cycle and improve nitrogen use efficiency. The chapter utilises 30 years' worth of data collected from over 90 different temperate field studies published between 1990 and 2020.…

Paperback. Zustand: New. Print on Demand. This book delves into the multifaceted nature of corn performance tests conducted in Illinois from 1936 to 1939. It provides a comprehensive examination of the standards and methodologies used in these tests, highlighting the key parameters evaluated, such as lodging resistance and sound corn yield. The data gathered from these tests sheds light on the genetic advancements made in hybrid corn during this period and contributes to our understanding of the factors influencing corn performance in various environmental conditions. The findings presented in this book serve as a valuable resource for researchers, farmers, and anyone interested in the history and science of corn improvement. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Paperback. Zustand: New. Print on Demand. This book offers a comprehensive overview of the ways in which hybrids have been and continue to be developed and tested. The author explains the methodologies and research techniques that are employed in hybrid corn production and performance assessment.

Buch. Zustand: Neu. Neuware - This volume presents the latest research on the development and use of communal spaces and places across the Mogollon region in what is now the southwestern United States and northwestern Mexico. New data demonstrate that these spaces and places, though diverse in form and function, were essential to community development and cohesion, particularly during critical formative periods associated with increasing sedentism and farming, and during comparable periods of social change. The authors ask questions crucial to understanding past communities: What is a communal space or place How did villagers across the Mogollon region use such places And how do modern archaeologists investigate the past to learn how ancient people thought about themselves and the world around them Contributors use innovative approaches to explore the development and properties of communal spaces and places, as well as how and why these places were incorporated into the daily lives of village residents. Buildings, alongside other types of communal spaces, are placed into broader cultural and social contexts, acknowledging the enduring importance of the kiva-type structure to many Native American societies of the southwestern United States and northwestern Mexico.…
