Advances in AGRONOMY Vol.31

---

Agronomy as a profession has a variety of meanings. But in all cases, it has a connotation that relates in some way to the production of crops. It is only natural that those scientists interested in crops and their culture find through agronomy a common interest with those interested in soils, the medium on which most crop plants grow.

Favorable weather in most parts of the world in 1977 and 1978 has permitted improved food production technologies to function. As a result, the yields of the primary food staples have increased and food stocks have risen to more accepta- ble levels. The technologies which have made possible this state of affairs are due in part to the work of soil and crop scientists and to their ability to communi- cate with each other internationally.

Contributions presented in this volume continue to give evidence of the inter- national exchange of scientific information. The authors of the seven articles are from five countries, and these articles relate to problems of international signifi- cance. The first, summarizing research on the effects of pesticides on soil mi- croorganisms, is in response to continued international concern with environmen- tal quality. Likewise, a review of factors affecting the loss of ammonia from soils has implications for environmental quality but more importantly for the rising costs of energy required to produce nitrogen fertilizers.

Three articles are concerned with basic soil properties, their measurement, and factors affecting them. Root exudates is the subject of one, a follow-up of an earlier Advances in Agronomy article on this general subject. The other two articles are concerned with soil chemistry, one with the movement of ions in soils. and the other with a unique way of measuring the availability of essential ele- ments in the soil. A review article on boron nutrition brings scientists up to date on our knowledge of this important element. In addition, the genetics of one of the world's most important forage crops, red clover, should be of keen interest to crop and animal scientists alike.
Thanks must be extended to the ten authors who prepared articles for this. volume. They have done a real service to their fellow soil and crop scientists.
