fibrophos is used widely across a whole range of crops. Replacing the nutrients removed and maintaining soil fertility are the key issues for farming today. As the nutrients in fibrophos occur in a very similar balance to those removed by cereals, regular applications of fibrophos ensure that the vital nutrients are replaced and kept in balance.

Effectiveness of fibrophos p and k on spring barley
| Objective And Method | ||
| Levington Agriculture Ltd | 1994 | LA Project 484 |
| 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 grown at Kirton in Suffolk 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 the untreated control and positive rates of fibrophos were significant. Less response was seen with MOP.
Highest yields were obtained with the fibrophos application.
Bushel weight: There was a significant increase in grain bushel weight with fibrophos. There was no significant increase in grain bushel weight from TSP and MOP.
Grain analysis: fibrophos increased the uptake of Potash and Sulphur in the grain compared 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.
Conclusion
fibrophos increased yields for both Phosphate and Potash treatments. Highly significant increases in specific weight were found.
Field trial on spring barley on high ph soils
fibrophos has been used effectively across a wide range of UK soils for a number of years. We wished to test the effectiveness of fibrophos in extreme conditions of chalky high pH soils.
| Objective And Method | ||
| Westcrop Ltd | 2002 | WCP-02-D44/6 |
| To evaluate the effectiveness of fibrophos on spring barley on high pH chalky soils. A free draining typical chalky downland calcareous flinty loam soil was chosen: ph 7.8Phosphate index 1 + Potash index 1Magnesium 0+ fibrophos 0-16-24 was compared with Kemira 0-24-24 Trials were conducted using recognised trial methods - full details are available |
||
Results
fibrophos and the standard fertiliser gave exactly the same response pattern over the range of rates applied
Conclusion
On this typical chalk downland soil, fibrophos has given both a statistically significant and economically useful boost to crop yield – this response is as good as conventional PK Fertiliser.
Field trial on winter wheat
| Objective And Method | ||
| Scottish Agricultural College | 1994 | David Cranstoun |
| To compare fibrophos alongside TSP/MOP on 4 replicated field plots. | ||
Results
The fibrophos treated plots out-yielded those treated with TSP and MOP. The soil P & K residual levels of fertiliser were also higher after fibrophos than TSP and MOP.
Conclusion
David Cranstoun (formerly SAC) comments: “For farmers trying to build up soils with low PK levels it is likely that fibrophos would be the more effective choice in nutrient terms than conventional PK fertilisers.”
