Advances In AGRONOMY Vol. 40

---

The contributions to this volume of Advances in Agronomy cover a range of
topics of current interest to crop and soil scientists. T wo are crop specific and
deal with important legumes. The first focuses on white clover (Frame and
Newbould: Agronomy of White Clover), the important pasture legume in
temperate regions. What is known about this crop, as well as its limitations, is
given coverage. Another chapter is a review of the current and potential role
of lupins as sources of plant protein for human and animal consumption
(Lopez-Bellido and Fuentes: Lupin Crop as an Alternative Source of Pro-
tein).
Two other contributions address issues involving soils. Hammond et al.
(Agronomic Value of Unacidulated and Partially Acidulated Phosphate
Rocks Indigenous to the Tropics) focus on the role of phosphorus in tropical
agriculture and on practical means of using indigenous phosphate deposits
to increase agricultural production. Gould et al. (Urea Transformations and
Fertilizer Efficiency in Soil) review the transformations of urea and their
implications for nitrogen supply and utilization. The world wide significance
of these transformations is shown by the serious losses of nitrogen resulting
from the transformation of urea nitrogen to other forms.
The article by Whisler et al. (Crop Simulation Models in Agronomic
Systems) deals with the building and testing of crop simulation models for
cotton, soybeans, and wheat. This pioneering work may well represent the
beginning of a new area of computerized models to govern on-farm manage-
ment decisions in not only the industrialized nations but also the Third
World.
I thank the contributors who prepared the five chapters that constitute this
volume. Researchers worldwide will appreciate their efforts
