I remember being shown around an agricultural research center and seeing how one team there was still using manual methods for determining the leaf area of their samples - cutting out leaf shapes from paper sheets and trying to count them. It was effective enough - but time-consuming and adding human error into all datasets. The moment this team acquired a leaf area meter, their processing times went down to hours instead of days, and their results started passing any peer review without any problems.
Why Is Leaf Area Determination Important Anyway?
Leaf area is not something that researchers usually do for the sake of doing it - it is used in order to determine plant's ability to photosynthesize and use the moisture effectively, its growth dynamics and many other things. People who conduct studies of plant yield, drought resistance or fertilizer response require accurate data in order to prove their hypotheses, and methods of leaf area determination by tracing leaf outlines or taking pictures of them with subsequent calculation of pixel amounts are both time-consuming and inaccurate, particularly if samples amount is large.
A leaf area meter can help solve this problem by providing instantaneous calculations of the leaf area along with its length, width and perimeter, after the leaf is scanned or photographed. If you conduct research that requires you to process hundred samples in a growing season, this instrument will help you stay on schedule.
Important Things To Consider When Buying
There are several aspects of a leaf area meter that people tend to ignore when choosing one:
- Speed of scanning - crucial for processing large sample amounts
- Accuracy at leaf outlines- particularly when dealing with non-uniform leaf shape
- Portability - necessary when conducting measurements in field
Compatibility of software with your existing research software - necessary for easy data exchange
If these things were ignored while selecting a particular device, researchers end up adapting their work according to the limitations of that particular meter.
Understanding Leaf Area Meter Price
The first question that people interested in leaf area meter price are asking is what makes the price vary. Portable field meters cost considerably less than precise laboratory meters.
Purchasing Leaf Area Meter in India
For academic institutions carrying out studies into leaf area meter cost in India, there has been quite some progress since now even the domestic manufacture of these meters is available. The local supplier may be quicker in terms of servicing and calibration – something that plays a much bigger role than anyone anticipates once the meter starts being used on a daily basis.
In case you are searching for a leaf area meter for sale, it is highly recommended that you ask for a demonstration of scanning – no matter how good a meter is said to be on paper, chances are that it will not be so accurate with your particular leaf types.
Final Thoughts
A leaf area meter can be considered as something relatively unimportant when it comes to the list of equipment in the research lab. However, its importance in terms of quality of the results received and overall efficiency is hard to underestimate.
