ZINC
Zinc helps with the cell growth needed for root system, forming of new leaves, for shoot growth and improved stress tolerance.
Things man has done to cause deficiency of zinc in the soil:
A deficiency usually will occur if heavy applications of phosphate fertilizer are added many years in a row.
Adding nitrogen to the soil that increases growth but depletes the availabe zinc.
Zinc concentrates in the top surface of the soil and when we scrap off the top soil we leave that soil barren of zinc.
Unless we loosen the soil we are using, zinc will be tied up.
Constantly taking heavy and high yield crops can deplete the soil of zinc.
Remember we need to feed the soil, especially with minerals. Get them here at
MINERALS .
