Fibrophos for root crops

The five nutrients most likely to affect

sugar beet are potassium (K), sodium

(Na), phosphorous (P), magnesium

(Mg) and sulphur (S). In addition,

boron (B) deficiencies are known to

damage beet yields. It is essential to

have adequate quantities of these

nutrients to prevent loss of quality or

yield. All are supplied by Fibrophos.

Trials were carried out to evaluate

the benefits of Fibrophos on

sugar beet which were inconclusive.

However, Fibrophos was seen to

yield as well when compared to TSP

and MOP with higher sugar yields in

the Fibrophos plots suggesting that

Fibrophos is as good a fertiliser for

beet as other fertilisers.

Conclusion

“Fibrophos was as effective as TSP/MOP in promoting growth of sugar beet

as demonstrated by colour and vigour assessments during the season”.

Fibrophos application increased root sugar content.

Conclusion

There were significant yield differences where fertiliser was applied but not

between Fibrophos and the comparable TSP and MOP suggesting that Fibrophos

is a suitable nutrient for potatoes. The results of the soil analysis showed

that Fibrophos can improve the soil K index by at least as much as MOP.

The results suggest that Fibrophos is as effective as conventional nutrient sources.

OBJECTIVE AND METHOD

The trial was designed to gain information on Fibrophos Extra-K as P & K source for

sugar beet at two sites in Cornwall and Suffolk. The treatments were factorially combined

so that each P & K source was tested at every rate of application.

Results

The plant vigour was significantly better on the treated plots and by June the rate

responses were visible. Colour of the beet leaves was likewise better. By the end of August,

the average score for vigour from the Fibrophos treatment was significantly greater than

that from TSP/MOP. Both Fibrophos and TSP/MOP tended to increase sugar content.

Maincrop potatoes grown on randomised replicated plots were compared with

conventional fertiliser as TSP and MOP.
