www.fao.orgTo assess the impact of drought, the FAO Agriculture Stress Index (ASI) is used as an indicator. ASI is based on remote sensing data that highlights anomalous vegetation growth and potential drought conditions in arable land during a given cropping season (Rojas et al., 2011). The main threat to crops is drought.

Therefore, if your tree blooms abnormally in September or October, it is safe to assume that the tree has been water stressed during the summer months. At a Glance • The first noticeable sign of water stress in a citrus tree is leaf curling. • Soil should be wetted from the trunk

Multi-year droughts, with their corresponding reduction in xylem size, have long-term impacts on plant growth potential. [Figure 3] Figure 3.
