Advances in AGRONOMY Vol. 1

---

Many sciences and skills contribute to the subject of agronomy; many
persons with widely different duties can properly call themselves agron-
omists. Not all of these agronomists would agree as to the precise defini-
tion of the word agronomy, yet all, in some way or another, have interests
that relate directly or indirectly to the growth of plants in soil. The
kind of professional training required of those studying the genesis and
classification of soils has few points in common with that required of men
engaged in genetical studies of a particular crop. Yet their fields of
activity are linked by their colleagues who must develop the proper
fertilizer recommendation for profitable production of adapted varieties
of that crop on various soil types.
The great body of knowledge about plants their nutritive require-
ments and growth, their management and improvement, their adaptation
and utilization-is continually expanding. It is becoming increasingly
difficult for many of those involved in one way or another in the theory
or practice of soil management and crop production to keep themselves
even reasonably well informed of the newer developments in all but their
immediate fields of activity. Progress is to a degree centrifugal in its
effects and through specialization tends to throw us apart.
This volume, Advances in Agronomy, has as its objective the survey
and review of progress in agronomic research and practice. The articles
are written by specialists. They are critical and reasonably compre-
hensive in treatment. They are written primarily for fellow agronomists
across the hall and across the continents who also find it difficult to keep
well informed in all phases of agronomy. The authors of this volume all
live on the North American continent, and it is primarily North Ameri-
can agronomy that is reviewed. It is not intended that this shall always
be the case, and contributions to later volumes will be sought from
workers in other countries overseas.
In the selection of topics for these volumes an attempt will be made
to include material that will be helpful to workers with diverse subject
matter and regional interests. The editors' definition of what constitutes
agronomy is catholie; they will be guided in their choice more by what
information may be of use to agronomists than by what constitutes agronomy. The central theme must be soil-crop relationships, for soils
without crops are barren and field crops cannot be considered without
reference to the soil on which they are produced. From time to time
articles may be ineluded that deal with related fields of horticulture and
forestry. The editors will take cognizance of other publishing plans, in
so far as they are known to them, in order to avoid duplication of
treatment. For example such considerations led them to omit from this
volume the subject of pastures. which was comprehensively surveyed in
the 1948 Yearbook of Agriculture, and the subject of soil classification
which was reviewed in a recent issue of Soil Science.
The editors wish to acknowledge the co-operation of the several con-
to the profession of agronomy
tributors to this volume, whose articles have been prepared as a service
