Verbatim
e0“Seedlings of alfalfa, rape, spinach, and wheat, potted on sandy soil, were irrigated with an aqueous extract of pea shoot”
e3“In comparison to water‐irrigated controls”
e4“had higher Ca, K, Mg, and organic N, but lower As and Ni contents”

Other claims from this paper (8)
- Intervention effect Pea-shoot extract irrigation increased shoot dry weight of the seedlings by 29–40% relative to water controls.
- Intervention effect Salt-solution irrigation (SS) increased shoot dry weight of the seedlings by 29–40% relative to water controls, nearly equal to pea-shoot extract.
- Intervention effect Pea-shoot extract irrigation gave higher fresh weights of the seedlings, by 38–84%, due to increased succulence.
- Intervention effect Pea-shoot extract irrigation gave higher Ca, K, Mg and organic N contents in the seedlings.
- Intervention effect Salt-solution irrigation did not enhance Ca, K, Mg and several trace element concentrations and sometimes reduced them.
- Association Lower metal contents in plant tissue were associated with lower metal solubility in the soil solution.
- Recommendation Continuous pea-shoot extract application replaces the Ca, K, Mg, P and organic N consumed by plants during growth.
- Association Pea-shoot extract use does not add relevant quantities of toxic metals to the plant-soil system.
