Temporal and spatial variations in crop performance are common in agricultural production fields in northeastern Arkansas. With the alluvial soils of the Mississippi Delta region, within-field soil texture can range from coarse sand to heavy clay. Such variability influences chemical and physical soil properties that affect yield potential of the region's commercial cropping systems. With advances in precision management, delineating large commercial fields into zones of homogenous production potential could increase profitability and improve efficiency. Standardized criteria for defining homogeneity within potential delineation zones have not been developed or field-tested in the region, which includes Mississippi County, Arkansas, the largest cotton (Gossypium hirsutum L.) production area in the US Midsouth. In this study, methods for creating management zones in spatially variable commercial fields were examined using multi-year yield monitor data from five commercial fields. Results showed that global and local Moran's I spatial analysis could identify areas of similarity of georeferenced yield monitor and apparent soil electrical conductivity (ECa) measurements. Zone delineation using cluster analysis of multi-year yield monitor data provided a more consistent delineation method than using soil ECa alone. The spatial analysis procedures outlined in this study provide guidelines for developing best management practices for delineating northeast Arkansas fields into zones representing homogeneous production potential. The study also included small plot and strip trials evaluating cotton response to crop inputs across spatially variable production fields. Results showed that cotton seeding density and irrigation timing could be adjusted to offset production inputs in low-yield potential delineation zones, thereby increasing net revenue. These data also were analyzed for sustainability scores using the Fieldprint® Calculator. With uniform application of inputs, cotton yield potential inherent to soil texture zones within the field was the most important factor contributing to improved natural resource sustainability. Weather patterns were such that irrigation did not improve cotton yield during the three years, and as a result, irrigation decreased the water use efficiency benchmark, thereby reducing the overall sustainability score. Future studies should be directed at measuring the sustainability impact of site-specific input applications based on sub-field production potential.

Encyclopedia of Agriculture and Food Systems, Second Edition, Five Volume Set addresses important issues by examining topics of global agriculture and food systems that are key to understanding the challenges we face. Questions it addresses include: Will we be able to produce enough food to meet the increasing dietary needs and wants of the additional two billion people expected to inhabit our planet by 2050? Will we be able to meet the need for so much more food while simultaneously reducing adverse environmental effects of today’s agriculture practices? Will we be able to produce the additional food using less land and water than we use now? These are among the most important challenges that face our planet in the coming decades. The broad themes of food systems and people, agriculture and the environment, the science of agriculture, agricultural products, and agricultural production systems are covered in more than 200 separate chapters of this work. The book provides information that serves as the foundation for discussion of the food and environment challenges of the world. An international group of highly respected authors addresses these issues from a global perspective and provides the background, references, and linkages for further exploration of each of topics of this comprehensive work. Addresses important challenges of sustainability and efficiency from a global perspective. Takes a detailed look at the important issues affecting the agricultural and food industries today. Full colour throughout.

This book presents the basic concepts of quantitative soil science and, within this framework, it seeks to construct a new body of knowledge. There is a growing need for quantitative approach in soil science, which arises from a general demand for improved economic production and environmental management. Pedometrics can be defined as the development and application of statistical and mathematical methods applicable to data analysis problems in soil science. This book shows how pedometrics can address key soil-related questions from a quantitative point of view. It addresses four main areas which are akin to the problems of conventional pedology: (i) Understanding the pattern of soil distribution in character space – soil classification, (ii) Understanding soil spatial and temporal variation, (iii) Evaluating the utility and quality of soil and ultimately, (iv) Understanding the genesis of soil. This is the first book that address these problems in a coherent quantitate approach.

Unmanned Aerial Systems in Agriculture: Eyes Above Fields bridges the gap between knowledge of concept and real-world use and operations of UASs in agri-production. Based on a valuable combination of themes presented at the 13th European Federation for Information Technology in Agriculture, Food and the Environment (EFITA) and supplemented by targeted invited articles of key-scientists, this book presents a full-spectrum view of the use of unmanned aerial systems (UAS) for agricultural applications. It integrates dispersed knowledge in the field, providing a holistic approach regarding UAVs and other UAS and their use in sustainable decisions. The integrated approach of the book provides a fresh look on contemporary agriculture-related issues, following precision farming approaches, by educating on a range of different issues of remote sensing and its use in agriculture. Furthermore, the operational planning aspects for UAS in agriculture focus part of the book provides information that is missing from other resources. Addresses practical issues and the latest technology application insights Provides specialized and comprehensive information for daily use-cases Ties remote sensing using aerial systems and precision farming issues

High yields and environmental control in crop farming call for precise adaptations to local growing conditions. Treating large fields in a uniform way by high capacity machinery cannot be regarded as a sustainable method for many situations. Because differences existing within single fields must be considered. The transition from former field work carried out manually or by small implements to present-day high-capacity machinery caused that the farmers lost the immediate and close contact with soils and crops. However, modern sensing and controlling technology can make up for this deficit. High tech methods that include proximal sensing and signals from satellites can provide for controls that allow adjusting farming operations to small fractions of one ha and sometimes even down to some m2, hence in a site-specific mode. This applies to operations for soil cultivation, sowing, fertilizing and plant protection. This book deals with site-specific concepts, applications and results.
