A liming invest! gat ion v*as conducted on nine representative
soils of Maryland. The importance of liming practices to agriculture
were discussed along with a brief h isto rical review of liming invest
igations. The need for a comparative lime study as a reference for
making lime recommendations for Maryland soils was pointed out.
Field experiments were set up on ’fattapex s ilt loam, Matawan
sandy loam, Sassafras s ilt loam, 'ionrnouth loamy sand, /lenelg loam,
Chester s ilt loam, DuffieId s ilt loan, and Emory s ilt loam so ils.
These soils were investigated over a three year period to determine
the influence of chemically equivalent amounts of coarse, medium and
fine grades of limestone, as well as burnt lime and hydrated liioe.
Each of these five lining m aterials was applied at two widely different
rates. The effects of these various liming treatm ents on crop response,
so il pH values, and exchangeable cations ¥/ere examined ov means of
field plot technique and laboratory analyses.
It was reported from the so il pH investigations that a ll
liming treatm ents employed increased the so il pH above the pH value of
the untreated so ils. However, the differences within the various
liming treatments were not shovm to be very great. The hydrated form,
of lime v?as shown to give the greatest effect on the so il pH value*
The different grades of fineness of limestone in the heavier application
rates used in this investigation did not give significant differences to
so il pH, It was concluded that an increase in the quantity of liming
m aterial added to the so il produced a larger increase in so il pH, The
greatest change in so il reaction was shewn to occur w ithin the firs t two
to four months after the liming treatm ent.
The data, concerning the influence of liming upon the exchangeable
cations, indicated that liming resulted in a decrease of exchangeable
hydrogen in the soils treated with both light and heavy applications of
lime when compared with the untreated so ils. It was estim ated that
approximately two m illiequivalonts of the liming m aterials used were re
quired to replace one m illiequivalcnt of exchan '©able hydro ■•en for the
acid soils studied. Soils treated with heavy anpli cat ions of lira© showed
a significant increase in exchangeable calcium above the values of the
untreated so ils. The data, as analyzed for a ll the so il types, showed
no significant change in exchangeable potassium, magnesium, or manganese
with the liming treatm ents employed.
The results indicated that there was no general decrease in the
ab ility of any of the lime forms to persist in the so il over the three
year period.
The hay yields of this experiment were generally increased by
liming. The heavier rate of application did not give as great a hay
response as the lighter application. This experiment showed no trend
toward increased yields of corn or wheat.
A direct relationship between the pH and percentage hydrogen-
saturation was shown to ex ist for a large group of Maryland so ils. By
use of th is pH and percentage hydrogen-s&turation relationship, a rapid
and an Improved method of estim ating the lime needs of Maryland so ils
was proposed.
