Remote sensing from unmanned aircraft systems (UAS) was expected to be an important
new technology to assist farmers with precision agriculture, especially crop nutrient …

Remote sensing could improve fertilisation by monitoring crop nitrogen (N) status using non-
invasive methods. The main goal of this experiment was to test the ability of proximal and …

Estimating crop nitrogen (N) status with sensors can be useful to adjust fertilizer levels to
crop requirements, reducing farmers' costs and N losses to the environment. In this study, we …

Agricultural drones are expected to revolutionize the way we conduct agronomic procedures
and maintain natural vegetation on earth. This book explores the increasing importance of …

A major component of an efficient farming strategy is the precise detection and
characterization of plant deficiencies followed by the proper deployment of fertilizers …

Recent development of non-destructive optical techniques, such as spectroscopy and
machine vision technologies, have laid a good foundation for real-time monitoring and …

Constant‐rate blanket applications of fertilizer N can result in both an over and under supply
relative to crop utilization on a field‐by‐field basis. Variable‐rate (VR) applications tailored …

The continuously growing need for increasing the production of food and reducing the
degradation of water supplies, has led to the development of several precision agriculture …

Abstract From 2005 through 2009, 282 on-farm evaluation trials were conducted in soybean
fields across Iowa to identify when a foliar application of pyraclostrobin produced profitable …

Methods of determining in-season corn (Zea mays L.) nitrogen (N) requirements and yield
estimates are needed for designing a resource-efficient corn production system that is both …
