Default Yellowing Lawn

Thanks for the reply . The yellowing is pretty uniform over the lawn. I
have now done soil tests , really surprised that nitrate phosphorus and
potassium show 'ow levels' with neutral pH. Why would it be so low when
a considerable amount of fine recycled compost was added to the soil
prior to laying turf and it has been fed this spring. A lot of recent
rain but surely that wouldn't wash out the nutrients. Considering the
test results a would a feed regime be the answer N:P:K 11 - 4 -8 ??
Noticed today there are now areas of small toadstools ........ Does
that indicate anything other than how wet it has been for a while. Any
further comments really appreciated . Thanks Steve G


the problem you are likely experiencing is that
you've added the compost to the soil and did
not wait, which ties up nitrogen until the organic
material gets broken down by fungi/bacteria. this
is why you would get both yellowing and toadstools
and why a nutrient test would come back poor in
nitrogen.

applying a fungicide will knock the fungi back short
term, but they are a natural part of any soil and
the goal is to get things back in balance, so waiting
is a good thing, adding a little nitrogen (very
weak solution so that what gets applied gets used
instead of ending up as runoff) will help green things
up.
