Observation and Site Analysis

Most bad farm designs are not designed badly. They are designed early. Someone walks a piece of ground once, likes the view, draws a plan at the kitchen table, and orders the trees. The land then spends ten years telling them what the first walk would have shown.

Observation is not a mood. It is a set of measurements you take before you commit money or labour. The list below is the one to carry outdoors, and every item on it produces a number, a sketch, or a dated note rather than an impression.

Read the slope first

Slope is the spine of everything else. It sets where water goes, where soil collects, where the machine can work, and where it cannot. Measure the grade, do not eyeball it. A smartphone level app or a homemade clinometer gives percent slope from two stakes and a string; ten percent is gentle enough to walk and mow, twenty-five percent is steep, thirty-five percent is ground you manage with hand tools and perennials or not at all.

Then walk the slope's shape. A convex slope sheds water fast and its shoulder dries first. A concave slope gathers water toward its base and holds frost. A uniform plane is rare. Note the breaks in slope, because each break is a natural place for a swale, a terrace, or a track.

On the Loop Farmstead parcel this matters in a documented way. The SSURGO survey puts the steep Gilpin and Peabody ground at a median topsoil pH of 4.7 to 5.0 with an A horizon only 8 to 11 centimetres deep, and the flat ground as dozer-made material at 0.5 percent organic matter. Same property, two completely different soils and two different jobs. Neither one is revealed by looking at the view.

Read the sun and the wind

Aspect decides heat. In the northern hemisphere the south-facing ground is warmest, catches the low winter sun, and thaws first in spring. North-facing ground stays cool and holds frost longest. East is mild, good for tender seedlings; west takes the hard afternoon sun and dries fastest. Watch the shadow of a post through a day, and again at the two solstices, to see how the sun's arc changes with season. That arc decides where a bed, a greenhouse, or a tree that will cast shade should go.

Wind is a thief you can see. It has a prevailing direction and a storm direction, and they are often different. Stand in it, note which trees lean and which sides are bare of branches, and mark where you would want a windbreak that does not shade the warm crop ground.

Read the water

You cannot read water on a dry day. Walk the ground in the worst rain of the year, and again the morning after, and watch where the water sheets, where it cuts a rill, where it pools and stands, and where it runs off the property entirely. Mark the exit points. Water that leaves is water you will haul back at the worst moment.

Read the soil and the plants

Soil is read with the hands and the nose before any lab. Take a fistful from a spade's depth: squeeze it, roll it, smell it. Grit means sand, a ribbon that holds means clay, dark and crumbly with a forest smell means organic matter is doing its work. Note the depth to a hard layer, and whether the colour changes under the topsoil, because subsoil is where roots have to live.

The plants already there are a reading too. Rushes and reeds signal wet, sweet ground. Sorrel and sheep sorrel signal acid ground. Short grass and thorns on thin soil signal a weak site. The Geoponica judged a whole field by its volunteer trees: large and numerous meant the most perfect kind, middling meant mediocrity, small shoots and short grass meant no strength.

Read the human patterns

Finally, read what people left. Old tracks, a filled ditch, a fence line running straight through a curve, a cut bank where a machine once worked, the direction water enters from a neighbour's ground. Access, existing buildings, and the nearest market or road are design constraints as real as slope. Cato told a buyer to visit more than once and to count the wine presses and storage vats, because the infrastructure tells you what the land has actually been doing.

The survey checklist

Carry this outdoors, and fill it in by hand.

• Slope: percent grade at three points, plus a sketch of convex, concave, or straight.
• Aspect: compass bearing of the main faces, and the shadow line of a post at noon on both solstices.
• Sun: hours of direct sun on the main growing ground, summer and winter.
• Wind: prevailing direction, storm direction, and where existing trees show damage or bare sides.
• Water: entry points, rills, pooling, and exit points, marked in the rain.
• Soil: texture by ribbon and squeeze, depth to hard layer, colour change depth, smell, and a jar test sample per zone.
• Plants: the three most common volunteer species per zone, and any wet or acid indicators.
• Human: tracks, old cuts, fences, buildings, access, boundary lines, and sightlines.
• Notes: date and time on every entry, because a hill changes with the season.
