Product Description


Ammonium Sulphate Fertiliser | N.P.K: 21-0-0

Our Ammonium Sulphate Fertiliser is an ideal solution to Nitrogen and Sulphur deficiencies within the soil, or to fertilise high alkalinity soils. This allows a more diverse selection of plants to be grown in an area. This is highly beneficial to leafy green plants as well boosting early growth, and providing them with a supply of Sulphur for later growth.

Suggested Usage Rates:

For Lawns:
The suggested application rate is 24g/sqm for usage on lawns, as grasses are quite sensitive to pH levels in the soil. However they do still benefit from the nutrients in this fertiliser.
Water your lawn or field thoroughly after application in order to maximise effectiveness.

For Vegetables:
Apply 35g/sqm as a top dressing to the soil surface and fork it in well.

Trees, Shrubs and Flowers:
Use 35g/sqm around established plants, whilst gently forking the fertiliser into the soil. Take care not to disturb the roots of the plant. Ensure that the fertiliser does not directly touch the stem or leaves to avoid “scorching”. After application water well.

We recommend checking the pH levels and Nitrogen/Sulphur levels within the soil before use. Avoid increasing acidity of the soil too much or over exposing plants to these minerals.
This fertiliser can “scorch” plants if applied directly onto them. It is common to be fork it into the soil around the plants, or mixed with water and sprayed over them as a diluted solution to minimise this.

Ammonium Sulphate Fertiliser nutritional benefits:

Nitrogen 21%: Nitrogen is key to the growth of leafy, green plants. It is a part of the chlorophyll, which make the leaves and stem green and allows photosynthesis to occur. Identify deficiencies of Nitrogen via pale green or yellow leaves due to a lack of chlorophyll. As these symptoms are similar to Sulphur deficiencies you can differentiate them by looking for a red colour along the veins on the leaves which shows that they are nitrogen deficient.

Sulphur 24%: Sulphur is considered an essential mineral as it is used to create important enzymes. It assists the plant in the formation of proteins encouraging healthy growth. A deficiency of Sulphur can be spotted by looking for plants that are overall a paler green or yellow colour. This will also stunt the plants growth significantly.
