Levington Agriculture Ltd
Ian Richards
The trial set out to evaluate Fibrophos as a phosphate source when applied to
grassland. The trial ran for three years. The soil chosen was a sandy clay with a pH
of 5.9. P & K indices were both 1. A randomised block, replicated 4 times was chosen.
A uniform dressing of N & K was applied in the spring and a single cut taken.
Fibrophos was compared with TSP and Rock Phosphate.
Results
Fibrophos for grassland
7
Fibrophos helps to raise the soil
phosphate and potash indices on
the poorest soils and together
with all the other key nutrients
naturally contained within it,
will help to increase yields across
the farm.
Regular applications of Fibrophos
ensure that phosphate and potash,
so vital for grass establishment, are
maintained and those important
secondary and trace elements
which are often overlooked, are
boosted to maximise grass yield and
improve the health of your livestock.
Fibrophos as a source for Grass
Conclusion
“Fibrophos is an effective phosphate source similar to TSP and superior
to phosphate rock in both grass dry matter and phosphate yield’’
