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

Optimal crop nitrogen (N) management is required to minimize N losses to the environment
in vegetable crop production. There are several approaches based on soil and plant …

Leaf area index (LAI) and chlorophyll content, at leaf and canopy level, are important
variables for agricultural applications because of their crucial role in photosynthesis and in …

In addition to single-angle reflectance data, multi-angular observations can be used as an
additional information source for the retrieval of properties of an observed target surface. In …

Imaging spectroscopy provides the opportunity to monitor nutrient status of vegetation. In
crops, prior studies have generally been limited in scope, either to a small wavelength range …

Predicting the grain yield during early to mid-growth stages is important for initial diagnosis
of rice and quantitative regulation of topdressing. In this study, we conducted four …

For farmers, the application of Precision Agriculture (PA) technology is expected to lead to
an increase in profitability. For society, PA is expected to lead to increased sustainability …

Agricultural intensification and efficient use and targeting of fertilizer inputs on smallholder
farms is key to sustainably improve food security. The objective of this paper is to …

Small unmanned aircraft vehicles (UAV) are potential remote sensing platforms for precision
agriculture. However, to be useful for in-season management, nitrogen status needs to be …

Precision agriculture is a farming management concept based on observing, measuring and
responding to inter-and intra-field variability in crops. In this paper, we focus on responding …
