Pentrometer

[David Humphries]

Would be appreciative of a nod in the direction of where I can get my hands on one.

 

Basically want to measure soil compaction on Veteran tree root plates, before & after diverting footfall/paths etc....

 

 

Preferably something like this.......

.........but from here in Uk.

 

 

Thanks

sorbus do Matthecks version.

[David Humphries]

Yeah i thought of Sorbus, but can't see it on the site.

 

doesn't appear to be under survey equipment/root detection.

 

Tried searching the site as well.

 

Did you speak with them at the seminar Tony?

cheers Tony.

 

 

 

Will have to get a quote by e-mail.

 

Is 260 euro plus shipping

 

 

 

Was thinking around fabricating one possibly, if import is too much hassle.

You should have a chat with the soil physics group at Rnthamsted Experimental Station before you do or buy anything

Have been thinking about this some more and magnus you have not said exactly what you plan to do but penetrometer results are very variable if you are looking o show improvements in bull density and porosity there are better ways of doing it

The soil penotrometer is adequate for basic evaluation, but if you have something of interest marcus then please elaborate as this is something I wish to learn more about.

[clueless]

not sure how you could fabricate one and reliably calibrate it?

 

i'd be keen to know if anyone knows of an online geotechnical equipment supplier though as i am looking for a shear vane myself

 

cheers
