Cemetery soil health is a mystery

Soil in church yards

CAUTION! This is seriously outside the box and possibly sensitive, but graveyards are great places to go – if you’re into soil.

As long as you’re not planning on staying indefinitely! 🙂

Think about it. The soil there should be really healthy.

Here’s why.

It is left undisturbed for relatively long periods. Traffic is restricted, mainly on a Sunday and for special events, and generally low volume – primarily limited to foot. And, everyone feels a bit funny walking over a grave don’t they?

Then you have the flora. The grass, hardy shrubs and trees.

Typically there is the odd Yew tree or two, abutting an ancient boundary or hedge or standing soldier-like on sentry on amongst the stone pieces. They are usually quite old and have co-evolved with soil itself, forming symbiotic relationships with the fauna that are too complex to comprehend, though will likely be significantly beneficial for fungi levels. The cover and the protection of the established green landscape and the shade afforded by the steeple tower, provide the first line of defence against climatic extremes.

Soil level is frequently elevated in the oldest of these traditional village settings. Contained within a wall, often many feet above other features in and around the site, like paths, gates and roadways. This is great for water drainage and maintaining optimal moisture content. I was led to believe (rightly or wrongly) that ‘coffins drifted underground’. Is this just an old wife’s tale or is the soil really so light, friable and free-flowing at this type of depth? I suppose it may be if it is occasionally being dug up and added to…

Then you’ve got the organic matter! Should be a pretty high %, shouldn’t it? We are made of soil, as we consume it, digest and absorb it in all its different forms. Eventually we are returned to it.

And head stones. Great supply of trace elements! As the granite or marble stone is gently eroded over time, years, centuries, the elements perculate through the soil, feeding it. Fuelling microbial interactions, nourishing plants and grasses.

So how healthy is the soil in a graveyard really?

I feel a soil test coming on though.

If you’ve ever tested soil in a graveyard, I would love to hear your experience. Or, if you have ever pondered this question, and are strange like me, also reach out.

Different I know. But if you enjoyed it, we’d love you support if you can click LIKE below.

Why test soil for life? Part 1: Moisture Content

In the first part of this mini-series we dangle our proverbial toes (or green fingers) in to the ground for a quick dip on understanding the importance of soil moisture and the relationship with microorganisms.

Moisture Content

Moisture content

Soil Moisture is calculated for soils and solid amendments, such as compost.  There are many different ways to determine this value, the most usual method for a soil analysis lab being the loss on drying method.  In this form, the value represents the level of moisture in given a sample as a percentage, that is to say the amount of, or mass, of a sample that is liquid (water) on an as-received basis.

The measurement will lie between 0 and 100%.  A zero value would indicate the complete absence of moisture, whereas 100% would probably have trickled to floor before it made it to the laboratory oven for drying!  It is sensible to track this metric throughout the season as climatic conditions change. If you need help with setting up a mechanism to capture and analyse you soil data, get in touch with MBS and ask for information on their Soil Surveillance System.

 

The importance of soil moisture being correct cannot be understated enough for a correctly functioning soil. It is a key parameter on any test report as the subsequent analysis for bacteria, fungi and protozoa depend directly on this value.

In the real-world, the liquid component is vital to the health of the soil ecosystem – assisting microorganisms with the fundamental requirements for their own survival as well as helping to mobilise nutrients to plants and allowing for movement between soil particles.  With a complete absence of moisture is unlikely that your microscopic workers will last for any great length of time, dying off or turning inactive until conditions change.  On the other hand, saturation will reduce the oxygen content, starving the microbes of the basic requirement of life forms and turn the soil anaerobic, promoting condition for harmful organisms.  In these extremes it is highly likely that you will have already observed the demise of your crop and taken to rowing across you field instead.

If you would like to get ahead and test your own soil for moisture content, health and more get in touch with Soibiolab and ask for more information on their services.

In the next installment of our series we will cover off Bacteria.
