Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain hay, relay production, quality, storage and safety from agricultural sources, describe windrows and aftermath, and distinguish hay from straw, silage, haylage and fresh pasture.

Grass, legumes or other herbaceous plants cut, dried and stored for use as animal fodder, especially for cattle, horses, sheep and goats, made by mowing, turning and raking into windrows, then baling; aftergrass or aftermath is the regrowth after a first cut, which may be taken as a second crop. Hay quality depends on plant species, maturity at cutting and drying conditions, and damp hay can overheat and ignite.

What it is for: Feeding livestock.

It can be explain production; relay quality and storage; describe related terms; distinguish related feeds.

Distinguishing features

Dried forage

Mowing and baling

Quality varies

Fire risk if damp

What it looks like

Dried green to golden grass in bales or stacks.

Physical character

safe baling moisture: about 15-20 percent - small bales

spontaneous combustion risk: above about 20 percent moisture note

common species: timothy, ryegrass, alfalfa, clover list

How it is recognised

Dried cut forage for livestock

Windrow, aftergrass, aftermath, bales

Straw is cereal stalks; silage is fermented wet forage; haylage is partly dried and wrapped; pasture is grazed fresh

What the second pass must settle

  • Should aftermath be a separate entry?
  • How should agricultural sources be linked?
  • The registry parent herbaceous plant confuses the product with the plant; should it be reviewed?
