This is the application of quick-acting fertilisers to the soil surface around plants to stimulate growth and is usually carried out in spring at the start of the growing season. Nitrogen applied to the soil surface is a t risk of losses volatilization so these applications are best timed with a rain to move the nitrogen into the soil.
