Liquid manures

Teas are made by either filling a container with the leaves or suspending a sack of manure in it. Then filling the container with water. Leave for about a week. Use it as a liquid fertiliser or foliar feed. Good on tomatoes, courgettes or house plants.

Comfrey	Rich in NPK

Manure

Whilst not strictly fertilisers these supply essential calcium.

Lime – Do not apply with manure. Leaches out of soil.

Calcified seaweed – Can be applied with manures. Granular form means it is not leached out & maintains ph level over long period. Rich in minerals that promote micro-organisms.

All the above are good used in the compost
