The number of root whorls of the plants is related with the ability to form shallower basal roots with different angles. This characteristic allows the plant to explore more volume of top soil where the less mobile nutrients, like phosphorus, are concentrated. The number of root whorls is considered as one of the root traits involved in the enhanced efficiency of nutrient acquisition on infertile soils.
