Download or read book Best Practices for Crop Area Estimation with Remote Sensing written by and published by . This book was released on 2010 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: GEOSS (Global Earth Observation System of Systems) is an initiative to network earth observation professionals and researchers. GEOSS promotes technical standards for different aspects of remote sensing. This document is one of them; it is dedicated to the use of remote sensing for crop area estimation. The purpose is giving a simplified summary of the methods and of kinds of satellite data that can be used in operational projects and those that still require research. Satellite data: Synthetic Aperture Radar (SAR) images cannot be considered operational for crop area estimation, except for paddy rice. Coarse or moderate resolution optical images are operational only for landscapes with very large fields. In general terms, pure remote sensing approaches are acceptable in two cases: when a ground survey is not possible (because local authorities are not involved or due to security problems) or when the accuracy requirements are looser than the commission/omission errors. Crop area forecasting several months before harvest is not operational in general, but interesting indications can be given if the uncertainty on cultivated area is high.

Available in PDF, EPUB and Kindle. Book excerpt: Dynamic monitoring of crop phenotypic traits (e.g., LAI, plant height, biomass, nitrogen, yield et al.) is essential for exploring crop growth patterns, breeding new varieties, and determining optimized strategies for crop management. Traditional methods for determining crop phenotypic traits are mainly based on field sampling, handheld instrument measurement, and mechanized high-throughput platforms, which are time-consuming, and have low efficiency and incomplete spatial coverage. The development of crop science requires more rapid and accurate access to field-based crop phenotypes. Remote sensing provides a novel solution to quantify crop structural and functional traits in a timely, rapid, non-invasive and efficient manner. With the development of burgeoning remote sensing sensors and diversified algorithms, a range of crop phenotypic traits have been determined, including morphological parameters, spectral and textural characteristics, physiological traits, and responses to abiotic/biotic stresses in different environments. In addition, research advances in varying disciplines beyond agricultural sciences, such as engineering, computer science, molecular biology, and bioinformatics, have brought new opportunities for further development of remote sensing-based methods and technologies to gain more quantitative information on crop structure and function in complex environments

This book was released on 2021-04-22 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advances in unmanned aerial vehicle (UAV) platforms and onboard sensors in the past few years have greatly increased our ability to monitor and map crops. The ability to register images at ultrahigh spatial resolution at any moment has made remote sensing techniques increasingly useful in crop management. These technologies have revolutionized the way in which remote sensing is applied in precision agriculture, allowing for decision-making in a matter of days instead of weeks. However, it is still necessary to continue research to improve and maximize the potential of UAV remote sensing in agriculture. This Special Issue of Remote Sensing includes different applications of UAV remote sensing for crop management, covering RGB, multispectral, hyperspectral and light detection and ranging (LiDAR) sensor applications aboard UAVs. The papers reveal innovative techniques involving image analysis and cloud points. However, it should be emphasized that this Special Issue is a small sample of UAV applications in agriculture and that there is much more to investigate.

Download or read book Forecasting and Classifying Potato Yields for Precision Agriculture Based on Time Series Analysis of Multispectral Satellite Imagery written by N. Tziolas and published by . This book was released on 2015 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on the development and evaluation of a method to estimate potato yields from remote sensing time-series at the field level, for 2013 and 2014 growing seasons. The aim is twofold, as research is done on both the entire growing season and in several time steps. On the basis of DMC's multispectral remote sensing data, the quantitative relationship between the NDVI (Normalized Difference Vegetation Index) and potato yield was analyzed and additionally the optimal period for predicting potato yield within the growing season was determined. Due to the changes of crop phenology among the years, an approach using information related to this phenomenon was investigated, aiming to enhance the performance of yield forecasting models. Having explored how far NDVI can be used as a stand-alone yield predictor, regression models were developed by incorporating meteorological factors. Additionally, besides the regression models, decision trees were used to analyze a qualitative relationship between yield and NDVI metrics, providing means to assess the relative performance of each technique in the context of explaining the yield variability of fields across the landscape.

This book was released on 2023-08-11 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precision agriculture is used to improve site-specific agricultural decision-making based on data collection and analysis, formulation of site-specific management recommendations, and implementation of management practices to correct for factors that can limit crop growth, yield, and quality. Various approaches for the remote sensing of soil fertility, water stress, diseases and infestations, and crop growth and condition have been developed and applied for precision agricultural purposes. With developments in remote sensing technologies, the spatial and spectral resolution and return frequencies available from both satellite and other remote collection platforms have improved to the point that the promise of precision agriculture can increasingly be realized. Unmanned aerial vehicles (UAV) in particular are providing newer and deeper insights, leveraging their high resolution, sensor-carrying flexibility and dynamic acquisition schedule. This range of remote sensing platforms has been used to estimate comprehensive information related to crop health and dynamics, providing rapid retrievals of leaf area index, canopy cover, chlorophyll, nitrogen, canopy/leaf water content, canopy/leaf temperature, biomass, and yield, amongst many other variables of interest. In combination, they allow for the expansion from local to regional scales and beyond. There has never been a greater opportunity for remote sensing data to enable precision agricultural insights that can be used to better monitor, manage and respond to in-field changes that might impact crop growth, health and yield.

Available in PDF, EPUB and Kindle. Book excerpt: Breeding Disease-Resistant Horticultural Crops is a complete and comprehensive resource for understanding the concept of breeding disease resistant crops, especially horticultural crops. Breeders of horticultural crops face distinct challenges that are different from agronomy/row crops, and these crops do not benefit from the vast body of literature available for agronomic crops. This book covers the basic theories that underpin breeding for disease resistance and features extensive real-world examples. Both classical and biotechnical breeding methods are covered, with an emphasis on how these methods are adapted for horticultural species. Presented in a logical flow for the reader, this book addresses historical perspectives and context as it relates to breeding for disease resistance. It highlights treatments of resistance in the context of the phenotype, the genotype, the pathogen, the environment interaction, sources of resistance, and the deployment of resistance to obtain a durable resistance. - Explores the definition of horticultural "resistance", how it is inherited, and how resistance can be manipulated through breeding - Highlights the importance of the interaction among crops, pathogens, and environmental elements - Provides the latest references and insights as a foundation for further research
