Book excerpt: This book focuses on the recent advances in precision agriculture and satellite farming, detailing applications for sensing, data handling, modeling, and control. In addition, the book reviews its history - establishing the background on the various processes and applications – describes the current status, and offers insight into the future technology of satellite farming in India. Introducing processes and applications based on a global scale, the book reveals how precision agriculture can be used in large-scale agriculture, community agriculture, and diversified farming. It includes site-specific information from a variety of information sources for planning, planting, growing, and harvesting agricultural crops. It also presents a new concept based on the control system theory that can be used to formulate systematic methods for more effective precision crop production. Precision agriculture when properly integrated into the crop production process, can greatly improve overall production and sustainability.
Download or read book Effects of Optical Sensing and Variable Rate Technology on Nitrogen Fertilizer Use Lint Yields and Profitability in Cotton Production written by Melissa Reynolds Stefanini and published by . This book was released on 2015 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen (N) fertilizer is expensive and can be harmful to the environment. Precision agriculture (PA) has the capability to reduce the amount of excess N from crop production released into the environment, increase net returns to the grower, and reduce the risk of profit loss due to spatial and temporal variability. The objectives of this study were to evaluate the profitability, risk management potential, and N use efficiency of using real-time optical sensing with variable-rate technologies (VRT) to manage spatial variability in cotton production. Data collected from 29 field trials in Tennessee, Louisiana, Mississippi, and Missouri from 2011 to 2014 included lint yields harvested and N rates calculated from three N rate management strategies. The first N treatment was the existing farmer practice (FP), the second was a VRT treatment using optical sensing technology GreenseekerTM, and the third was a VRT treatment using GreenseekerTM and yield monitor information. The two PA strategies were compared to the existing farmer practice. In addition, soil properties and weather were examined to determine their effects on lint yields, net returns, N rates, and N use efficiency. Three methods used in this study each include an analysis of lint yields, N rates, net returns, and N use efficiency. The first model was an analysis of variance (ANOVA) to identify treatment mean differences. The second model was an ANOVA that measured soil and weather effects on mean differences between technology and FP. The third model was a logistic analysis to test for risk of a loss using VRT. Results indicated differences in technology net returns versus the FP and no differences between VRT and FP in yields, N rates, or N use efficiency. Warmer temperatures were negatively associated and a greater percentage of organic matter had positive associations with VRT net returns and N use efficiency relative to FP. Profit risk management benefits were identified using GreenseekerTM versus the FP. Results can be used by Extension offices and cotton farmers in Tennessee, Mississippi, Louisiana, and Missouri to determine if adopting optical sensing and VRT would be beneficial to their operations.

Download or read book Farm Profits and Adoption of Precision Agriculture written by U.s. Department of Agriculture and published by Createspace Independent Publishing Platform. This book was released on 2017-02-15 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precision agriculture (PA) and its suite of information technologies-such as soil and yield mapping using a global positioning system (GPS), GPS tractor guidance systems, and variable-rate input application-allow farm operators to fine-tune their production practices. Access to detailed, within-field information can decrease input costs and increase yields. USDA's Agricultural Resource Management Survey shows that these PA technologies were used on roughly 30 to 50 percent of U.S. corn and soybean acres in 2010-12. Previous studies suggest that use of PA is associated with higher profits under certain conditions, but aggregate estimates of these gains have not been available. In this report, a treatment-effects model is developed to estimate factors associated with PA technology adoption rates and the impacts of adoption on profits. Labor and machinery used in production and certain farm characteristics, like farm size, are associated with adoption as well as with two profit measures, net returns and operating profits. The impact of these PA technologies on profits for U.S. corn producers is positive, but small. Keywords: Crop production information technologies, precision agriculture, variablerate technology, soil tests, global positioning system maps, guidance systems.

Download or read book Precision in Crop Farming written by Hermann J. Heege and published by Springer Science & Business Media. This book was released on 2013-07-03 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
