I want to measure the root volume of wheat for my experiment which requires uniform uprooting of wheat plants with a specified volume of soil. What will be ideal core sampler size so that root can be uprooted without any significant damage?
Hello Sudhradip
The simple answer is as large as possible, as it gives a better average, but what is possible depends on other factors - what soil are the plants growing in - how deep will you want to sample - how will the cores be driven and pulled out - how will you extract the roots or are you only interested in the depth to which roots penetrate? Root sampling and measurement is a very labour-intensive activity!
Best of luck

It is little bit difficult and tricky to measure wheat roots while grown in field in normal soil, idea of uprooting does not seem practical here. For this purpose better to plant wheat in other way for example using hydroponics or may be tubes or germination papers.
Regarding Muhammad's answer - I assumed that the information required was about a `normal' agricultural context as soil was referred to (although I did not respond to the point about damage) and roots and plants grown hydroponically do differ from those grown in soil, Caution is needed about aims and methods of achieving them.
To extracting roots of wheat is quite difficult from soil as compare to other growing methods like hydroponics and pot culture, but i agree to David sir suggetion that as much as possible keep the wider sized one ( 200-250 mm) but it will be difficult to uprooting the whole volume of soil and roots, And also consider the depth too.
