HESKETT SLAG Many soils of high-rainfall parts of New Zealand lack Lime, and contain large quantities of Iron and Allumina, which rob the farmer of about four-fifths of every ton of WaterSoluble Phosphates spread on these soils; a Basic Slag contains, among other minerals, large quantities of a nonacid chemical compound known as Calcium-Silico-Phosphate which, it is claimed, has the power of unlocking these dormant minerals from the soil. The phosphates of a Basic Slag cannot be locked up by these soils because they are already combined in a form easily digested by the root acids as they need them. Made in New Zealand for New Zealand Soils. Finely ground and packed 18 bags to the ton, it is delivered f.o.r. Huntly, Waikato. Obtainable from Merchants and Dairy Companies or from the Chief Distributors— Arthur Yates & Co., Ltd. Whangarei : AUCKLAND : New Plymouth
