Precision Agriculture (PA) is an approach to managing the variability in production agriculture in a more economic and environmentally efficient manner. It has been pioneered as a management tool in the grains industry, and while its development and uptake continues to grow among grain farmers worldwide, a broad range of other cropping industries have embraced the concept.<br><br>Readers will gain an understanding of the magnitude, spatial scale and seasonality of measurable variability in soil attributes, plant growth and environmental conditions. They will be introduced to the role of sensing systems in measuring crop, soil and environment variability, and discover how this variability may have a significant impact on crop production systems.<i>Precision Agriculture for Grain Production Systems</i> will empower crop and soil science students, agronomy and agricultural engineering students, as well as agronomic advisors and farmers to critically analyze the impact of observed variation in resources on crop production and management decisions.
