No-till fields can require less phosphorus fertilizer because not tilling a field vastly improves the health of the soil, said Steve Culman, a soil fertility specialist with Ohio State

How and why to keep phosphorus on no-till fields
By Alayna DeMartini
Ohio State University
Left untilled, fields gain organic
matter and maintain high yields, but
there's a tradeoff to consider when
deciding not to till.
Fields that aren't tilled are less
likely to erode, sending soil and the
components of fertilizer, including
phosphorus, downstream, a threat to
water quality.
However, when rain runs off a field
that's not been tilled, that rain is more
likely to carry with it phosphorus in
a form that can be readily available
to produce algal blooms downstream,
said Warren Dick, a retired soil
scientist from Ohio State University
College of Food, Agricultural, and
Environmental Sciences (CFAES).
That's because fertilizer in a no-till
system is not mixed into the soil and
often stays at the surface, making it
more vulnerable to running off with
rainwater.
A major cause of the harmful
algal blooms plaguing Lake Erie
every summer is phosphorus that
runs off farm fields with rainwater.
Phosphorus is most harmful to water
quality when it's in its dissolved
Same field.
More yield.
For healthier soil and better
quality crops
Use Polysulphate®
fertilizer to
supply plant-available sulfur,
potassium, magnesium and
calcium in a single application.
Polysulphate's prolonged
availability of nutrients reduces
the risk of leaching and gradually
releases the key nutrients to the
growing crop, improving yield,
quality and profits.
