The application of lime is a long-term agricultural
benefit.
However, despite acting over a long
period of time, lime makes a tremendous difference to the productivity of all farmland,
both in real and economic terms.
Lime
and Fertiliser Utilisation
The availability of plant nutrients is affected by the pH of the soil. The chart
below shows the scale of availability. Significantly, this illustrates the increasing
unavailability of the major plant nutrients, nitrogen, phosphate and potash (N, P and K)
with a low pH, acid soil.
Acid
conditions also show a marked reduction in availability of calcium, magnesium and sulphur.

Plant Food Availability and Plant requirement charts
Soil is a medium, which enables worms and microorganisms to break down animal and
plant residues. This assists plant development but also produces soil acids, which have to
be kept in balance if the process is to continue.
The
build up of acidity places plants under stress and reduces their ability to utilise plant
nutrients and organic matter.
Acid
soils display significantly reduced bacteriological activity
Lime
and Stock Well Being
Well-limed
pastures encourage the growth of palatable and nutritious clovers and grasses
(e.g.
perennial ryegrass) to replace the more acid loving meadow foxtail, agrostis and other
weed grasses. The control in limed and unlimed grass plots is shown below with the less
palatable weed grasses clearly visible on the unlimed area.
Trials
conducted by ADAS show liming will increase the percentage of calcium within a plant and
will encourage grass growth with a higher nutritional value for livestock.
Lime
and Agro-Chemicals
The efficiency of some pesticides, insecticides and residual herbicides applied to
the soil can be affected by acidity of the soil. Soils deficient in lime absorb chemicals
more strongly than well-limed soils and thereby reduce the effect of the chemicals.
