What about keeping plants well watered?

Sulfur Metabolism and Stress Defense Responses in Plants

“…Stress can be defined as any alteration in normal plant growth conditions (Boaretto et al 2014). Some of these alterations are related to temperature, salinity, water supply, ozone, soil acidification and heavy metal toxicity, among others (Azevedo et al 1998;Bulbovas et al 2014;Medici et al 2014;Nogueirol et al 2015). Studies of plants have been conducted to evaluate the effects of these changes on growth and development.…”

Automatically controlled deficit irrigation of lettuce in “organic potponics”

“…The economy in water and nutrients for plant cultivation will depend on the efficiency of the sensorbased controllers for irrigation to avoid either drainage or drought, which causes waste of water or growth limitation, respectively (Cia et al, 2012;Boaretto et al, 2014;Medici et al, 2014). The lack of such controllers at a low cost and ready to be used in commercial conditions may explain why precise irrigation is rarely used for growing plants in pots, as most use timers or manual control (Montesano et al, 2016).…”

Land and Water Management Strategies for the Improvement of Crop Production

“…Traditional surface irrigation methods predominate (.90% of the global irrigated land area), and have relatively low WUE (e.g., index of field application efficiency in gravity surface and drip irrigation system reaches 0.5 and 0.95, respectively). Improved WUE and beneficial environmental impacts (reduced nutrients use/leaching, improved food quality) can also be achieved by optimizing irrigation management strategy to use (1) irrigation on plant demand (maintaining the rhizosphere moisture close to the water potential required to meet the full crop ET demands) or (2) deficit (supplemental) irrigation (substantially below the full crop ET demand) (Bos et al, 2009;Medici et al, 2014). Improved WUE and beneficial environmental impacts (reduced nutrients use/leaching, improved food quality) can also be achieved by optimizing irrigation management strategy to use (1) irrigation on plant demand (maintaining the rhizosphere moisture close to the water potential required to meet the full crop ET demands) or (2) deficit (supplemental) irrigation (substantially below the full crop ET demand) (Bos et al, 2009;Medici et al, 2014).…”
