Plants need to receive adequate nutrition to grow to the best of their abilities, and we can help by adding fertilisers to the soil. Organic fertilisers such as decayed farmyard manure and compost are effective for soil improvement, while compost is also a valuable source of nutrients. Granulated cow-manure, poultry manure, blood-meal and bone-meal are also excellent sources of gradually released nutrients.
Inorganic fertilisers only contain nutrients and have no influence on soil structure or soil life. The three most important elements for good plant development are nitrogen, phosphorus and potassium. In spring an all-round fertiliser, such as phostrogen powder, can be scattered. In summer, rapidly growing plants can be given extra fertiliser. However, inorganic fertilisers shouldn’t be used exclusively for years on end, as they will eventually damage the soil structure and soil life.
