Context & Scope

Context

Users see PermaplanT as mere tool to replace books and their notes. PermplanT envisions designing maps:

  • collaboratively
  • for agricultural purposes
  • enabling fully documenting all plants:
    • for garden tours
    • for tracking harvesting
  • reminding about what you don't see:
    • watering
    • fertilization
  • with mulching
  • but no dig

Out of Scope

Later features that are out of scope for first version:

  • weather data (automatically add rain to watering layer, warnings on frost etc.)
  • hints&tips about pest control, fertilizer, care, etc.
  • automatic shadow and moisture calculation
  • 3D modes (forest garden), contour lines etc.
  • time-lapse of historic garden development, simulate growth
  • positions and distances relate to the real world, for example, you can use GPS coordinates
  • GIS import/export

Input Parameters

Soil

Global value and local values in the Soil layer:

  • soil texture (German: orientiert an Bodenschwereklasse nach ÖNORM L 1050 auf Basis des österreichischen Texturdreiecks bzw. Bodenartendiagramms (ÖNORM L 1061) (Klassen))
  • pH base value for topsoil from 0-14 (German: Bodenreaktion, e.g. Kohl basisch, ph3 Heidelbeeren), dynamic value using one decimal digit after the comma:
    • 1 very acid (pH 5.0 and below)
    • 2 acid (pH 5.1 - 6.5)
    • 3 neutral (pH 6.6 - 7.3)
    • 4 alkaline (pH 7.4 - 7.8)
    • 5 very alkaline (pH 7.9 and above)
  • pH base value for subsoil from 0-14
  • yield grade (German: Ages Gehaltsklasse (Nährstoffversorgung und Humusgehalt) ÖNORM L 1210, determined from NPK, eigentlich für Intensivkultur, Stark/Schwachzehrer) from:
    • A sehr niedrig
    • B niedrig
    • C ausreichend
    • D hoch
    • E sehr hoch

Out of Scope

  • (Temperatursumme/Jahresmitteltemperatur) first version: use data from Ostösterreich
  • (Vegetationsperiode) first version: use data from Ostösterreich
  • (sun background: Sonnentage, Sonnenscheindauer h, from https://www.data.gv.at/katalog/dataset/1d9754ae-9e7b-4772-97c9-a030285d75bb) first version: use data from Ostösterreich
  • (soil depth, BM: Bodenmächtigkeit: Mächtigkeit des durchwurzelbaren Mineralbodens (cm)) first version: assume "sehr tiefgründig" > 100cm
  • (SkelG: Skelettgehalt: Anteil der Korngrößenfraktion > 2 mm (Grobanteil) am Mineralboden (%)) first version we assume geringer Grobanteil <= 10%
  • Available water capacity
  • Field capacity

  • (Gesamtniederschlag - Verdunstung) first version: use data from Ostösterreich

Local (for each place in the Garden)

  • distances to plants/trees (German: Abstände zu Bäumen/Sträuchern)
  • wind
  • shadows
  • surface water, i.e., wet/dry places (German: Oberflächenwasser)
  • habitats
  • permaculture zones, see glossary
  • events: e.g. elements in the garden get added/removed accurate to the day

Out of Scope

  • soil amendments
  • mulching (Mulchen)
  • influences of street (German: Einflüsse durch Straßennähe, wie Salz und Staub)
  • automatic overshadowing (German: Baumkronenüberschattung)

Output Parameters

  • which seeds are needed (seedling plants excluded)
  • coordinates of plants to plant
  • warnings (violation of natural constraints etc.)

Out of Scope

  • weather alerts
