Request a sales quoteThe Soil-Root Interface contains the proceedings of an international symposium held in Oxford, England, on March 28 to 31, 1978. The first five chapters of this book contain the majority of papers presented at the meeting, as well as the descriptions of displayed posters and films. Abstracts of other contributions offered by participants but not read at the meeting form the final chapter. The first five parts cover topics on nutrient demand and supply at the soil root interface; physics and chemistry of the interfacial region; biological activities at the interface; the interface in relation to environmental stress and disease; and the interface in relation to soil function and growth.
