What is the Difference Between Granular and Liquid Fertilisers

Granular Fertilisers:

• Form: Granules or pellets.

• Application: Spread evenly across the lawn using a broadcast or drop spreader.

• Release Rate: Typically, slow-release, providing nutrients over an extended period.

• Advantages:

• Long-lasting effects, reducing the frequency of applications.

• Easier to store and handle.

• Less likely to cause nutrient runoff if applied correctly.

• Disadvantages:

• Slower absorption into the soil.

• Requires watering in to activate the nutrients.

• Uneven distribution can occur if not applied carefully.

Liquid Fertilisers:

• Form: Liquid concentrate or ready-to-use solution.

• Application: Applied using a hose-end sprayer, backpack sprayer, or watering can.

• Release Rate: Typically, quick-release, providing immediate nutrient availability.

• Advantages:

• Fast-acting, with nutrients quickly absorbed by the grass.

• Easier to apply evenly across the lawn.

• Can be mixed with other liquid treatments (e.g., weed control, wetting agents).

• Disadvantages:

• Needs more frequent applications compared to granular fertilisers.

• Higher risk of nutrient runoff if over-applied.

• Requires careful mixing and measuring to avoid over-fertilisation.
