A little time consuming to navigate. First define you AOI... Area of Interest.

I have two types of fine sand; Myakka and Malabar. And the water table is 4 to 18 inches below the surface!

Appling hard labor complex:

Appling:

0-8 inches Sand Loam
9-35 - Sandy Clay
35-46 - Sandy Clay
46-65- Sandy Clay Loam

Hard Labor (which is what it is digging in it I presume....)

0-3 - inches Sandy loam
3-7 - Coarse Sandy Loam
7-32 -Clay
32-65-Sandy Clay Loam

For us it came back as sandy loam eroded. If I look further it says that the land is terraced and clay at 14" (if I remember right)

So...My thought and what matches the property, is that most of the the lot is a thin layer of decomposed organic material covering clay. But in places the sandy loam has washed down the slope and in some places stayed. Guessing most of our good sandy loam got scrapped off decades ago when the areas main road went through

It would be neat to actually figure out how to use this - I back up to a small river, although I'm considerably higher than the river regardless of season. I'd guess I'm silty, but there's a lot of rock too. Eh, I'll just continue on in my ignorance!

Soquel loam, 2 to 9 percent slopes

Loam My Sainted Aunt Fanny! If I have loam, it's in my gutters.... Out in the yard, it's measurable in millimeters. The slope is correct, as long as you're inside my fence. Outside my fence, my slope on the river side is pretty much vertical.

Still and all - thanks for posting that link. It was interesting.

They did not import the adobe clay that they used to make houses with back in the day.

And I don't even bother with a rototiller on the lot, first because it would tear me up if I hit something with it and second, if I rented one I would need the unlimited damage waiver cause it is going to be bent and broken when I return it. I still have one large vintage rototiller I am using as "yard art" (aka too heavy to lift in the truck to haul out)

But I hauled off 2 or 3 older ones my dad broke over the years.

Some twit dumped a few tons of 1" granite gravel over most of my lot. Only at the very back edge have I found dirt without the gravel. In the front flower bed, under my house, under both decks, ALL the driveway, around back to the back fence... In the driveway the gravel isn't very deep, mostly 1" layer of rock, sometimes 2" if it's not where the tires generally go. In the flower bed, under the house, it's at least 3-4 inches... Out back it varies. There are also several boulders, either sitting up tall and proud (in the front flower bed) or barely surfacing (out back) and you never really know if the rock you see isn't moving because it's stuck, or it's huge and NO digging will removed it short of a backhoe. It's exhausting, and would not be safe to rototill at all. Somebody would lose an eye either from the gravel, or a piece of tine that snapped off and went flying.

That loam they think I have is probably outside my fence, on that vertical hillside, underneath the blackberry vines, ivy, and whatever else is back there. I don't know, I can't get there.. Maybe that's why my blackberry vines are So Healthy they come up in the front yard? The ivy comes in on all 3 sides. I've weed whacked it, hand snipped it, and RU'd it. My bad... I didn't see any mention of a water table, maybe because I'm right next to the river?

The decomposed granite washes down constantly from the hills above. It is absolutely sterile -- no organic content at all, and if it settles around the base of a plant, it will block all water, and the plant will eventually die. (We learned that the hard way.)

In really big El Nino floods, big chunks of sandstone like stuff has washed down the hill, from the ravines above, and landed here and there, filled with small fossils.

Where the hillside has been cut away for building, you can sometimes be right at the clay level, and there, the drainage is so bad that, early on, we had to dig down and backfill with rock, to make drainage, where we wanted to plant.

If there ever was any sort of loam here, it was washed down over the decades to add to the 10-ft-deep topsoil, out on the Oxnard Plain.

Meaning, at one time some of this was fine sand stone up on the mountains/foothills and was washed toward the sea.

As a kid long before they spent weeks grading the lot next door, when it would rain, the back of the neighboring property would flood and fill with water taking days and days to drain.

When we worked that land for our farmstand, we would find indian fish hooks. Much of the water was at one time pumped from an aquifer just around the corner. And a nearby house was referred to as "the boat house" It was down where it was once swampy land. Our house in on the top of the hill. If you try and dig on the fence line with one neighbor, you get the worst slimey clay-it will stick to your shoes and stick out flat and wide so big you have to take off your shoes and let it dry to break it off. And if you dig more than a little bit, you are right back in to that clay. Some is a dark dark color (guessing that is from the bottom of the swampy zone. The clay by the house is more an adobe brown)

One thing, when you add fine sand to clay, mix and bake in the sun, you can make some hard art projects.

I would think that the geologists don't take samples every 20 feet or so. There is no mention of my "toxic rubble landfill" that may have been added when my street was first paved decades ago. We are in a swampy flood plain.

However, just up the strret less than 500 feet, the survey says it has Seffner sand there. In another direction there is a pond which I thought was a retention pond. The site says that is yet another soil type.

This deck is under a large old oak tree, and next to a medium maple - and the leaves are falling faster than I can sweep them up. Rain is arriving tomorrow, and I though it would be a good notion to clean out the spaces.... The ground under the deck is now 'improved'!

Evidently, I can get a yield of 25 tons of Corn and Tomatoes, and 90 crates of Celery. Lemme check the current prices on the commodities market; it might be time to get rid of these darn roses and start farming.
