Under‐as well as overfertilization with nitrogen (N) will result in economic loss for the farmer
due to reduced yields and quality of the products. Also from an ecological perspective, it is …

We have characterized a new commercial chlorophyll (Chl) and flavonoid (Flav) meter
called Dualex 4 Scientific (Dx4). We compared this device to two other Chl meters, the SPAD …

Relationships between chlorophyll concentration ([chl]) and SPAD values were determined
for birch, wheat, and potato. For all three species, the relationships were non-linear with an …

Leaf chlorophyll content (μg cm− 2) is an important variable for agricultural remote sensing
because of its close relationship to leaf N content. The objectives of this study were to …

The SPAD-502 meter is a hand-held device that is widely used for the rapid, accurate and
non-destructive measurement of leaf chlorophyll concentrations. It has been employed …

Leaf chlorophyll content (LCC) is an indicator of leaf photosynthetic capacity. It is crucial for
improving the understanding of plant physiological status. SPAD meters are routinely used …

The aim of this work was to assess the effect of leaf thickness, leaf succulence (LS), specific
leaf area (SLA), specific leaf mass (W s) and leaf water content (LWC) on chlorophyll (Chl) …

Accurate measurement of leaf chlorophyll concentration (LChl) in the field using a portable
chlorophyll meter (PCM) is crucial to support methodology development for map** the …

The estimation of chlorophyll content in leaves by the chlorophyll meter (SPAD 502) is more
convenient than by the extraction method for studies on photosynthesis or senescence …

The aim of the present study was to examine the interactions between an endogeic
earthworm species, Metaphire posthuma, and purely mineral (control) or mineral plus …
