Samenvatting door auteur toon abstract
Part 1 discusses the influence of a number of physical factors, particularly moisture conditions. The most important of the trials were on the effect of soil moisture on fruit-trees, in particular on growth of shoots and fruits, fruit set and initiation of mixed buds. The watertable was of significance for the water supply necessary for rooting; standards were given for optimum humidity. The water and air balance of sample plots in an orchard with different soil profiles were estimated and differences were compared with the reactions of fruit trees. Finally water consumption and the optimum water table were considered.

Part 2 considers how soil chemistry influenced the trees. Critical values for the relation K/Mg were given as a measure of Mg deficiency. The influences of soil humidity, calcium status, nitrogen dressing and soil cover or soil vegetation on Mg deficiency were also studied. A number of soil factors or groups of soil factors were involved in the occurrence of iron deficiency. Standards were derived for zinc content of leaves, and some factors involved in zinc deficiency were detected. N deficiency was also studied.

How the standards derived could be applied to soil management in practice is indicated in the final chapter.
