Various aspects of soil suitability research in horticulture are explained by results from asparagus (a moderately intensive crop) and apple (more intensive) outdoors, and tomatoes in heated greenhouses (very intensive). The less intensive the crop, the clearer the limit the soil set in yields, because, for intensive crops, it was more economic for the grower to adapt to the soil by crop management and soil improvement.

Yield, quality and the economics of asparagus were strongly influenced by the soil. Rooting depth was an important factor and depended on penetration resistance. In layers with a high resistance (30 kgf/cm 2), roots did not occur, as in C horizons of sandy soils. For the apple Jonathan on finetextured river clays, growers could allow for soil limitations by planting trees closer together. Tree growth was influenced more by a soil layer with a bad structure than was yield per m 2covered by the trees.

In trials with tomatoes in heated greenhouses soil had little effect if management was optimum. More rapid plant growth and lower fruitset on the first trusses on sandy soil than on clay soils were explained by differences in available water. Water is stronger bound by clay soils than by sandy soils, but crop management could correct for differences between soils.
