Fibrophos

[farm]

If using fibrophos on high mg soils using urea will any calcium lime be needed to keep ph right.

It dose have neutralising property's but not a lot. 18% iirc but you dont put that much on.

So lime will be needed aswell

Depends where your starting from !

If say 6.5 ph when fibrophos applied

Arable or grassland ? Inputs? Etc

Arable 200 kg/ha of n urea

Depends on soil analysis.

It wouldn’t be worth an extra pass with lime at pH 6.5, the ground will be sweet enough at that.

The only issue I have with Fibrophos is the spreadwidth, in that *some* contractors treat it as a waste and apply it too wide with little overlap to get rid of the pile quickly, rather than regard it as the valuable input that it is.

I could recommend you a very good contractor that make s a good job of spreading fibrophos if you need one.

Is the amount of lime reduced by using fibrophos over the long term

Depend on how fast your land eats lime, depends on how much nitrogen you use depends on how much fibrophos you need and apply, its possible but a bit like asking how long is a bit of string.

Personally I have found ph to be more stable where I have used fibrophos.
