Biomass | I Am Doing A Science Fair Project On Plants And I Need Help With An Easy Way To Measure Biomass?

I need to know how to measure the biomass of above-ground plants. I am growing these plants with different African-animal dung. If you have any simple ways so measure biomass or any good websites please let me know! Thank you.

Just to add to the other answer, it’s standard to dry plant and soil materials at a temperature of about 105 C (221 F). If you go much higher, you run the risk of burning the materials.See if you can use a food dehydrator for this — the kind used to make beef jerky, etc.One problem you might face is that you have a LOT of biomass, and you don’t have the capacity to dry it all. If that happens, cut the biomass down and let it air dry for a few days. Weigh the total weight of the biomass, then take a small sample, weigh it, and put it in your dehydrator.When the sample you put in the dehydrator is dry, weigh it again and calculate the percentage of water that was in the sample:(orig. weight of sample – dry weight of sample) / (orig. weight of sample) = decimal percent waterMultiply the decimal percent of water by the total weight of the biomass to get the dry weight of biomass of your ‘harvest’ from that animal dung treatment.


The scientific way to do it is dry biomass, cut off the bit you want to measure, bake it for a long time at medium/low heat to dry it out completely without burning it then weigh it.
