What's It For? - Sulphate of Ammonia
Sulphate of Ammonia is a well-established, quick-acting, growth-promoting fertiliser with a response normally seen in about 10 days. Its main use is to give a rapid boost to established, quick-growing vegetables and salad crops. It is also a very effective spring tonic for shrubs, fruit and spring greens.
Apply it from April to September. Sprinkle it evenly between the rows of vegetables and under the full branch spread of trees, shrubs and fruit bushes (1oz per square yard). Hoe or rake it in and, if dry, water well for maximum benefit. Do not apply as a heap at the base of the stem and shake off any that lodges on the foliage. It may also be dissolved in water (1oz in 2 gallons) and used as a liquid feed. A light sprinkling over the surface of a compost heap each time the height rises by about 6 inches will speed the rate of compost production by 'feeding' the organisms responsible for the degradation process.
