Farmland wiki

The water that the soil retains and the plant can effectively extract, measured in millimeters up to a certain depth.

A scale from I to VIII that answers a single question: what is this land for, from agriculture without limitations (I) to without agricultural suitability (VIII).

The carbon stock in the first 30 cm, in tons per hectare; it is the best available indicator of organic matter.

The official survey that divides the territory into units and describes the soil of each one; its scale decides how much detail it has.

The proportion of sand, silt and clay in the soil, which decides how much water it retains and how it is worked.

A number from 0 to 100 that summarizes the agricultural suitability of a unit of soil: the higher, the better the soil.

The finest level of classification: a specific soil, with its described profile and its own name.

Excess salts or sodium in the profile, which restricts what can be grown and penalizes the value of the land.

Each polygon the soil survey map divides the territory into; it is the smallest unit there is data for.

The height of a point above sea level, measured against the official Argentine reference.

The height difference between the highest and lowest point of the property; tells at a glance whether it is even or uneven.

How much the terrain slopes, in percentage; it decides the erosion, if the machinery enters and if it can be irrigated by gravity.

Rain minus the water that the environment can evaporate, adding the twelve months: it tells if there is excess or lack of water, something that rain alone does not say.

A number that combines rainfall and temperature to place the climate on a scale from arid to very humid, comparable between regions.

How much rain the location receives in an average year, in millimeters; below ~600 mm, rainfed agriculture is no longer reliable.

Surfaces where a flooding event was recorded; it is proven history, not a forecast.

The permanent and temporary bodies of water surveyed in the Pampas plain.

The hierarchical code that locates a parcel within the territorial division of the province.

The unit of land with its own boundaries and number recorded by the provincial cadastre; it is the legal definition of the property.

The account number with which the province identifies the parcel for real estate tax.

The value the province assigns to the land to calculate the tax; it is not the market price.

The productive destination declared by the person publishing: agricultural, livestock, mixed, forestry or other.

What was actually planted on the farmland last season, detected by satellite at 30 m resolution.

How much green, active vegetation there is on the plot, measured by satellite every fortnight; the curve across the year shows when it was sown, how much it grew and when it was harvested.

The provincial ordinance that classifies the native forest into three categories and defines, by law, whether it can be cleared.

The distance that must be respected to apply phytosanitary products near a town, a school or a watercourse; it is set by each province and each municipality, not a national law.

Ten thousand square metres: a hundred metres on a side, and the unit farmland is measured and priced in.

Everything added to the farmland that adds value; not all of it is buildings.

The value of land per unit of area, which is how farms of different sizes are compared.

How far by road are the terminals where what the field produces is shipped. It is one of the factors that most moves the value of land, along with soil.

What share of the farmland actually has data from a layer; the rest is not made up, it is declared empty.

The size of the smallest detail that a layer can distinguish; below that, the data does not separate a lot from its neighbor.

Marks values computed on a sample of pixels rather than all of them, when the farmland is very large.
