Editing Safflower (section)

===Soil===
Safflower prefers well-drained, neutral, fertile and deep soils.<ref name=":4" /><ref name=":3" /> It can adapt well to soil pH (pH 5–8) and tolerates salinity.<ref name=":3" /> Safflower can be well grown on different soil types, with water supply as its main driving factor for suitability, depending on climate and irrigation, and the resulting different water regimes of the different soil types.<ref name=":4" /> Therefore, cultivation on shallow soils and especially on soils with danger of waterlogging is not suitable.<ref name=":5" /> The deep rooting promotes water and air movement and improves the [[soil quality]] for subsequent crops in a rotation.<ref name=":6" />

Nutrient requirements can be compared to wheat and barley, except nitrogen amendment should be increased by 20%.<ref name=":4" /> Therefore, soils with an adequate nitrogen supply are favorable.<ref name=":5" />
