Fibrophos Handbook 2015

OBJECTIVE AND METHOD

Levington Agriculture Ltd

Ian Richards

To evaluate the effectiveness of P & K in Fibrophos when applied to spring barley.

A replicated trial was carried out by Levington Agriculture on spring barley on soil with

a pH of 7.5, P index 1 (low) and K index 0 (very low).

Fibrophos was compared with TSP and MOP.

Results

Yield:

There was an upward trend in yield with increasing rate of Fibrophos for

both phosphate and potash. The difference in yield from untreated control

and positive rates of Fibrophos were significant by Duncan’s MRT.

Less response was seen with MOP. Highest yields were obtained with

the Fibrophos application.

Bushel

There was a significant increase in grain bushel weight with Fibrophos.

weight:

There was no significant increase in grain bushel weight from TSP and MOP.

Grain

Fibrophos increased the uptake of potash and sulphur in the grain compared

analysis:

with TSP and MOP. N:S ratios measured in the Fibrophos treatments gave

good ratios which indicated deficiencies were unlikely. Fibrophos significantly

decreased the N content of grain at the lower rates of application.

Fibrophos for cereals

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 a much more

productive acreage of your farm.

Regular applications of Fibrophos

ensure that phosphate and potash,

so vital for crop establishment,

are maintained across your farm

and those important secondary

and trace elements which are

often overlooked, are boosted to

maximise crop yield.

Field Trial on Spring Barley

Conclusion

“Fibrophos increased yields for both phosphate and potash treatments.

Highly significant increases in grain specific weight were found.”
