This paper will focus on highlights and recent advances in understanding the importance of micronutrients for crop production. We will not discuss Fe, as this is the subject of regular international meetings (the 11th Symposium was held in Udine, Italy, in June, 2002 and papers published in Journal of Plant Nutrition, Vol 26). Besides, Fe is different from the other micronutrients in that there is relatively little use of fertiliser to correct the disorder despite the extent of the problem. The consequences of grain nutrient composition for humans and animals are dealt with in other papers, as are the effects of micronutrients on efficient use of macronutrients.

The most complete recent review of micronutrients was published in 1991 (Mortvedt et al. 1991). Subsequently, International Symposia on zinc (Robson 1993), boron (Dell et al. 1997; Goldbach et al. 2002) and silicon (Datnoff et al. 2001) have updated knowledge on each of those elements.

Whilst we have tried to highlight principles and emerging trends, where possible we have used examples with which we are familiar from collaborative research in Asia (especially Thailand and China) and Australia.
