“…In the current study increasing Na application decreased WSC in grass, a finding inconsistent with that of Chiy andPhillips (1993, 1998). Low WSC concentration in timothy grown on organogenic soil without K application may be related to a severe K deficiency and consequently reduced growth rates.…”

“…The effects of Na fertilization on herbage cell wall concentrations have been variable. In the present study and those of Chiy et al (1993Chiy et al ( , 1994 and Chiy and Phillips (1996), concentrations of cell wall constituents were marginally, but significantly increased with Na fertilization, whereas Chiy and Phillips (1998) and Cushnahan et al (1996) reported no effects. Chiy et al (1994) attributed a higher modified acid detergent fibre (MADF) concentration with Na fertilization to increased herbage growth rates enabling maturity to be attained faster.…”

“…Zalacáin et al (2019) also reported an increased Na concentration in leaves of plants irrigated with TME over a 15-year period. Elevated concentrations of Na in pasture increase its palatability to stock Table 6 Mass of N and P (kg/ha equiv., unless otherwise indicated) in the TME, pasture, soil and drainage water over the entire lysimeter experiment (17.5 months) (Chiy et al 1998), and farmers occasionally apply Na to their pastures for this reason. Although most pasture species are not overly sensitive to Na, the maximum concentration found in leaves (0.6%) can be toxic for some sensitive plants (Ayers and Westcot 1985).…”

“…Further uptake of nitrate is therefore reliant on transport of nitrate from the roots to plant shoots, a process which requires K 20. In addition to reducing nitrate leaching through its positive effects on leachate cation concentration, Na fertiliser also increased forage K concentration in Na‐fertilised plants,21 thus facilitating the transport of nitrate from root to shoot preventing the negative feedback mechanism on nitrate absorption.…”
