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 fertiliser types and nutrients, support choosing and applying fertilisers safely in gardens and farms, describe environmental effects and regulation with attribution, and describe production and history.

A substance applied to soil or plants to supply nutrients such as nitrogen, phosphorus and potassium, including mineral fertilisers such as potash and ammonium compounds, organic fertilisers such as manure, compost and plant teas, and specialised products for aquatic plants, hydroponics and gardens; fertilisers raise yields but require careful use to avoid pollution of water and air, and are regulated for composition, labelling and use.

What it is for: Supplying plant nutrients.

It can be explain types and nutrients; support choosing and applying; describe environmental effects and regulation; describe production and history.

Distinguishing features

Nutrient supply

Mineral or organic

Yield effect

Environmental risk

What it looks like

Granules, powders, liquids or organic materials such as manure.

How it is recognised

Supplies plant nutrients

Mineral or organic

Soil conditioners improve structure rather than supply nutrients

  • How should application guidance be localised?
  • How should regulations be linked?
