Secondary Elements in Fibrophos
5
Magnesium deficiency in the first
cut where TSP/MOP was applied
was significant. The overall uptake
of magnesium by the grass in this
deficient soil was greatest where
Fibrophos was applied, with TSP/
MOP resulting in a significantly
lower uptake.
Key points
•
Helps correct soil magnesium deficiencies
•
Higher yields
•
Improves feed value of grass
•
Reduced risk of staggers
•
Less disease (reduces plant stress)
•
Better quality (helps keep plants green)
General background notes on magnesium:
•
Magnesium recommendations are generally based on available Mg levels
(soil analysis) and are expressed as Kg/MgO/Ha
•
Magnesium levels in grass are influenced by application of nitrogen and potash
•
Inadequate supplies of magnesium in grass can lead to grass tetany
•
Feeding standards recommend not less than 0.18% Mg in dietary dry
matter for milking cows
Conversion:
[Convert Mg to MgO x 1.66]
“The effects demonstrated are important for grazing animals where
magnesium is an important constituent of their diets. Fibrophos did not
show the antagonism found with MOP against magnesium”
