SS-AGR-463/AG462: Plant Essential Nutrients and Their Role …
Plants need 17 essential nutrient elements to complete their life cycle (i.e., growth and reproduction) (Table 1). Carbon (C), hydrogen (H), and oxygen (O) are provided by air and water, and there is little control over the availability of these nutrients. For most plants, these three elements make up 94% or more of the dry tissue.

This strong location effect will need to be considered in estimating potential benefits of Zn biofortification. Our data furthermore showed that it was not possible to simply compensate for low soil Zn availability by fertilizer applications. In all soils fertilizer Zn was taken up as seen by a 50–200% increase in total plant Zn content.

A cost-effective approach to estimate plant available water …
The PAWC is the maximum amount of water the soil profile can retain for plants to use (Burk & Dalgliesh, 2008). The PAWC interacts with pre-season rainfall, in-season rainfall, water infiltration, runoff and evapotranspiration to impact the amount of plant available water (PAW) at any given time (Verburg et al., 2021).
