Orange is a perennial crop, grown in a wide range of soil types, from sand, through loam to clay, acidic to alkaline. Climate: arid to humid. Minimum temperature is the limiting factor, though the killing effect varies with variety, rootstock, trees dormancy, the absolute minimum temperature and its duration. Best orange mineral nutrition regime includes the use of fertigation with fully-soluble fertilizers, and foliar feeding. CRF in the plantinghole is used during planting of young trees.
