I’ll by no means use the phrase “frequent as filth” once more. My cliché vocabulary has expanded.
Widespread as silt loam? Positive. Widespread as sandy clay? Completely. Identical frequent as sandy clay loam, although that is a mouthful.
These are phrases I realized after coming throughout an intriguing competitors held this month at UNH’s Kingman Analysis Farm in Madbury: the Interscholastic Soil Judgment.
“It is about describing the soil, its bodily traits. Is it sandy, loamy, clayey? Is there a excessive water desk? Are you able to see bedrock? Is it glacial until or marine sediment? Are you able to assess what the soil can be utilized for? mentioned Alena Warren, director of the Stafford County Conservation District, which organized the competitors.
The competition has been held for many years, however is just selecting up once more after the pandemic snuffed it out, which is why solely Moultonboro Academy’s AP Environmental Science class attended the Oct. 6 occasion. Subsequent 12 months ought to appeal to extra faculties and see the return of some severe underground pupil scrums.

By the best way, it isn’t a bizarre factor in New Hampshire. Do an Web seek for “soil analysis competitions” and you can see them held on each continent. America even has a Nationwide Collegiate Soil Judging Championship. It was gained this 12 months by Virginia Tech, whose public relations division boasted that the college gained particular person, group and group awards, the primary such sweep since 2015! Sports activities workplace, take observe.
The competition at Kingman Farm was fairly simple. Pits about 4 toes deep had been dug at numerous areas on the farm, giant sufficient for 2 individuals to stroll into on the identical time and study the cross-section of various soils.
“It is type of a singular place, which is why we do it right here. There’s glacial until, glacial outwash and marine sediment solids inside strolling distance, and inside these three classes there are locations with excessive water desk, totally different drainages,” Warren mentioned.
Soil samples had been dug out for the scholars to the touch and scent – possibly additionally style? – to move judgements. Conservation specialists and soil scientists had been available to document the outcomes and, extra importantly, reply questions.
The purpose of all of that is to assist teenagers perceive what is going on on underground from apparent indicators like sand and fewer apparent indicators like redoximorph options (“like rust spots within the floor”) . This, in flip, helps them make selections about how and whether or not to make use of the land.
“Folks suppose it is fairly telling that you may get all this data simply by digging a gap,” Warren mentioned. “It exposes youngsters to totally different careers that they could not have recognized about: soil scientist or researcher, home builder, highway builder, septic tank fitter, forester – all of those individuals must know this stuff on the bottom.”
And farmers, in fact.
There’s a saying that each one of human civilization depends upon six inches of topsoil and the correct amount of rain. This column has talked concerning the rain extra occasions than I can rely however by no means actually bought into the filth. Disgrace on me.
As quickly as that is dropped off, I will seize a shovel and head to my discipline, see if I can inform the distinction between sandy loam and sandy loam as a result of apparently they’re totally different.
Want me good luck.
