Ph Level 5.3 what ferliliser should we use?
We have just recently had some results back from a soil analysis. The Ph Level of the cricket square is 5.3 which is too low.
Other info from the cricket square is as follows
The organic matter is 9.28%
The bulk density of the sample was 1.37Mg m-3
Coarse sand 0.38
Medium sand 0.8
Fine sand 2.97
Total sand 4.15
Silt 52.45
Clay 43.4
What advice have our colleagues out there for what fertilisers we should use.
Any other pointers would be useful.

Ph
Matthew,
I think more info is required here, firstly, how the hell did you get the Ph that low! I would love to get my bowling greens down there! Unfortunately the Perrenial Rye that is on your square must be suffering greatly as this type of grass definately hates a Ph that low.
How is the grass looking (pale / dark), is it growing (at all?)
cheers, Dave

Ph Levels
No idea how the Ph level got that low. Something done over time, i suppose. Grass is struggling and pale. The grass is growing.
Any help still required!

pH
Use a sulphur free organic containing potassium carbide and seaweed as a fertiliser.This is non acidifying and potas carbide is alkaline so it will induce a rise in pH, as required, and continue to monitor.Hope this is some help Pete.

PH level
Matthew, as David suggested- you really also need a soil chemical analysis to give readings of nutrient requirements. Without this test, as has been said on many occasions before, you will fall into the trap of total guesswork. If you dont know what is in the soil in terms of chemicals and nutrients then find out before wasting money. Chemical analysis then feed.cheers JB.

PH, 5.3 what fertiliser should we use?
you have the results of a soil test which provides PERCENTAGE FRACTIONS OF SAND, SILT AND CLAY. These results are used when choosing compatible top dressings and NOT changing ph through fertiliser application. What you require, to change ph is a soil chemical analysis test, without this, there should be no advice given WHATSOEVER on fertiliser requirements, if someone gives fertiliser advice without chemical data, be very wary.
cheers jb.
