fertilizer based on ammoniacal nitrogen and sulphur: the nitrogen has a progressive and durable release, without losses due to leaching, whereas the sulphur carries out an acidifying action in the soil, and is therefore recommended for applications on calcareous and alkaline soil and for the feeding of acidophil plants and lawns.
scatter 30-40 g/m2 (about one handful) at the time of the soil preparation and at the beginning of the growing season. For fruit-bearing plants it is advisable to scatter 60-80 g (about 2 handfuls) per plant according to the foliage size.
