Soil Structure Test - need some help with analysis please
after the very good advice i have recieved from a few of you, on my recent blog about 'freaky soil' - thank you all for the advice. yesterday i did as both Grenville and Lori have advised and done a soil structure test, we already know that my soil is very acidic after i did a ph test a couple of weeks ago. i am now looking at the structure...i would say on first glance this looks quite good - hope the picture is clear enought to see well.. i can see 4 layers here, possibly 5 as the sand seems to be very gritty on the bottom and finer towards the top of this layer, but overall it looks to me like i have at least 45% maybe as much as 50 sand, - it is difficult to be accuate on this as the jar tappers down at the bottom - next time i will use a straight one- but we live and learn lol.
next their seems to be a thinish layer would say approx 20-25% of a grey/brown stuff. Next a slightly thicker layer approx 25-30% of what i would say looks like clay. then a thin layer approx 10% of a very light colour stuff that swirls about a bit if i move the jar - could this be play sand? it is much finer than normal sand. and yes i have approx 5% of OM floating on the top. so does this look like a good structure?
