Both products are easy to integrate into any
fertility program and can either be applied to
the soil as a drench or to the foliage as a fine
spray. For best results, mix thoroughly with
water until fully dissolved.

COMPATIBILITY RISKS WHEN MIXING
SULPHATES AND CHELATES
Using sulphate micronutrients alongside
chelated micronutrients can introduce
compatibility challenges. Free metal ions
from sulphates — particularly copper, zinc,
and manganese — can displace iron from its
chelate. When this occurs, iron may precipitate
and become unavailable to plants.

Depending on pH and solution conditions, this
exchange can result in iron losses of 20–50%,
increasing the risk of iron deficiency. To reduce
this risk, chelated forms of manganese, zinc,
and copper are recommended whenever
chelated iron is used.

PLANTEX® NUTRITRACE CSM FERTILIZER
®
Plantex NutriTrace CSM Fertilizer is a water-
soluble fertilizer mix of chelated secondary
micronutrients which can be used as a
preventative supplement or as a corrective
application where known deficiencies exist.
By supplying micronutrients in a chelated
form, growers reduce the risk of precipitation
and maintain availability of those nutrients for
plant uptake.

KEY TAKEAWAYS
Chelated micronutrients improve availability
by protecting nutrients from precipitation and
®
®
oxidation. Plantex Iron Chelates and Plantex
NutriTrace CSM Fertilizer are key tools for
greenhouse growers looking to prevent
deficiencies and manage micronutrients in
their crops. By incorporating these highly
effective products into their nutrient programs,
growers can ensure their plants have access
to necessary nutrients for healthy growth and
optimal yields.
