Net Assimilation Rate
Compute the simplified net assimilation rate in grams per square metre of leaf per day as dry mass gain divided by average leaf area times elapsed days.
Description
Compute the simplified net assimilation rate in grams per square metre of leaf per day as dry mass gain divided by average leaf area times elapsed days.
Net Assimilation Rate is a focused biology tool that compute the simplified net assimilation rate in grams per square metre of leaf per day as dry mass gain divided by average leaf area times elapsed days. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use Net Assimilation Rate
Use Net Assimilation Rate when you need to compute the simplified net assimilation rate in grams per square metre of leaf per day as dry mass gain divided by average leaf area times elapsed days. Enter Elapsed time, Initial dry mass, Final dry mass, and Average leaf area using the definitions and units below so the result can be reproduced.
- Elapsed time
- A finite measured or assumed value, expressed in days.
- Initial dry mass
- A finite measured or assumed value greater than or equal to 0, expressed in g.
- Final dry mass
- A finite measured or assumed value greater than or equal to 0, expressed in g.
- Average leaf area
- A finite measured or assumed value, expressed in m².
How Net Assimilation Rate calculates the result
The published tool contract uses this rule: Compute the simplified net assimilation rate in grams per square metre of leaf per day as dry mass gain divided by average leaf area times elapsed days.
- Net assimilation rate
- The calculated net assimilation rate in g/m²/day.
Limitations of Net Assimilation Rate
A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small.
Alternative or Complementary measurements
Retain the original Elapsed time, Initial dry mass, Final dry mass, and Average leaf area values and their units alongside the result. Net Photosynthesis Rate is useful when you instead need to compute the net photosynthesis rate in micromoles of carbon dioxide per square metre per second from uptake and leaf area. Crop Growth Rate provides another view by helping you compute crop growth rate in grams per square metre of ground per day as standing dry mass gain divided by ground area times elapsed days.
