Liquid Zinc Sulphate
Directions for Use
Zinc is not mobile in the soil and needs to be placed near the emerging plants root system or if a blanket spray is used it needs to be evenly distributed over the soil surface and thoroughly cultivated into the topsoil.
Zinc deficiencies occur mainly in high pH soils and can be effectively locked up especially in calcareous soils, however consistent applications of robust rates does build up Zinc levels in the soil.
