Water is the medium through which every nutrient travels from soil to root. Without adequate moisture, even nutrient-rich soil becomes inaccessible to plants — roots simply cannot absorb dissolved minerals from dry particles.
Measured continuously by NutRE™'s electrochemical sensors as part of every full soil reading.
Leaves lose turgor pressure and curl inward to reduce surface area and water loss — often the first visible sign.
Roots stop elongating in dry soil, reducing the plant's ability to forage for both water and nutrients.
Even if fertiliser is present, dry soil prevents dissolution — nutrients sit inert and unusable.
Under water stress, plants abort flowers and immature fruit to conserve resources for survival.
Illustrative comparison — actual symptom severity varies by crop species, growth stage, and the presence of compounding deficiencies.
