Quick supplement nitrogen, supplying calcium and boron directly. Boron is the main element of promoting flower and fruit swelling. It is also efficient in disease resistant, crack resistant and crops quality improvement, which is widely used for greenhouse and large areas of agricultural land. It is a free-flowing material. Its hygroscopic nature means that it readily dissolves when in contact with the soil in humid conditions or a night dew. This formulation offers low risk of scorch and is often used as a final topdressing to a wide range of high value crops that have a requirement for extra boron.
