Improvements of nitrogen use efficiency (NUE) may be achieved through the use of sensing
tools for N status determination. Leaf and canopy chlorophyll, as well as leaf polyphenolics …

Agriculture faces the challenge of providing food, fibre and energy from limited land
resources to satisfy the changing needs of a growing world population. Global megatrends …

The Soil Plant Analysis Development (SPAD) chlorophyll meter is one of the most commonly
used diagnostic tools to measure crop nitrogen status. However, the measurement method …

Context Late-season nitrogen (N) application has been proposed to boost grain yield and
grain protein concentration (GPC) in cereals; however, its effects on bread and durum wheat …

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 …

Enhancement of water and nitrogen use efficiency simultaneously may provide advantages
over optimization of water and nitrogen inputs separately. In addition, water is the driver of …

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 …

Intensive vegetable production is commonly associated with excessive nitrogen (N)
fertilization and associated environmental problems. Monitoring of crop N status can …

Fertilizer nitrogen (N) is one of the major inputs in rice–wheat production systems in South
Asia. As fertilizer N has generally been managed following blanket recommendations …

Measuring the nitrogen nutrition status of plants is useful for nitrogen fertiliser management.
As nitrogen is one of the main structural components of chlorophyll, its nutrition status is …
