“…The increased Mg uptake is probably partially attributable to increased soil solution Mg concentrations (Edmeades et al 1985a(Edmeades et al , 1985b. The fact that plant Mg concentrations decreased indicates that some dilution effect, as suggested by Edmeades et al (1983b), has occurred. In addition, increasing solution Ca concentrations can interfere with plant Mg transport from the roots to the tops (Morgan & Jackson 1976), thus resulting in reduced plant Mg concentrations.…”

A mowing trial was conducted on the Mangatea clay loam (a yellow-grey earth or Umbric Dystrochrept fine hallositic mesic) to examine the mechanisms causing lime responses in a grass/ clover pasture. The trial site was located on a sheep and beef farm 8 km south of Te Kuiti, New Zealand. The site generally had cool winters and warm moist summers, with an annual rainfall of about 1400 mm. The treatments consisted of 3 lime rates (0, 5000, 10 000 kg ha -1 ) in the absence of P and 6 lime rates (0, 1250, 2500, 5000, 7500, 10 000 kg ha -1 ) in the presence of P (50 kg P ha -1 yr -1 ), all in the presence of sodium molybdate (Mo), and an additional treatment where P was applied in the absence of lime and Mo. Lime increased grass yield but decreased clover yield for the first 2 years after application. In Years 3 and 4, the responsiveness of the grass decreased and that of clover increased. Lime increased net N mineralisation by up to 58 kg ha -1 , resulting in increased grass growth. Plant P uptake in both grass and clover also increased when lime was applied. However, yield responses were only seen in summer in clover when plant P concentrations in clover were less than 3.0 mg g -1 . The lime-induced increase in Mo availability would contribute to lime responses if basal Mo was not applied. Subsoil Al toxicity, particularly in summer, was limiting growth in some parts of the trial. However, there was no evidence that Mn toxicity was limiting yield, nor of any lime-induced trace nutrient deficiencies. Results from the application of P and Mo indicate that there was at least a 6-month delay in the transfer of N from clover to grass, with about 30% of the extra clover N uptake in Year 1 being transferred to extra N uptake in grass in Year 2.

“…Pasture Ca concentrations in both clovers and grasses exhibit strong seasonal trends as demonstrated in seven sites on the East Coast (Metson & Saunders 1978) and one site in Taranaki (Edmeades et al 1983b). Pasture Ca concentrations are lowest in the winter and spring and highest in the summer.…”

“…There is some evidence that liming may increase soil exchangeable-potassium (K) and -sodium (Na), because of an increase in soil cation exchange capacity (Edmeades 1982;Edmeades et al 1983). Theoretically this may result in a reduced input of these nutrients on some soils but further research is necessary to quantify this effect.…”

“…However, there is no experimental evidence to support this. The major and most consistent effects of liming on pasture mineral composition are to decrease Mg and manganese (Mn), and increase calcium (Ca) and Mo (During & Rolt 1967;McNaught et al 1968McNaught et al , 1973aMcNaught et al , 53 1973bLambert & Grant 1980;Edmeades et al 1983;Thomson 1981). Generally, liming has little effect on concentrations of the macronutrients P, nitrogen (N), sulphur (S), K, Na, or of the micronutrients Cu, boron (B), and cobalt (Co), over the pH range of 5.0-6.0 usually encountered in agricultural practice ).…”

A lime recommendation scheme for established pastures on mineral soils is described. The scheme is based on a simple model, using soil pH, to estimate the size of pasture responses to lime at 3 rates of application (1.25, 2.5, and 5.0 t/ha), The estimated pasture production responses to lime are converted to increases in animal production, from which the potential economic benefits of Iiming are calculated. The limitations and accuracy of the model are discussed. The importance ofliming relative to fertiliser nutrient inputs is also discussed and, in particular, it is concluded that lime and fertiliser inputs should be assessed independently. Recommendations for the use of lime on organic soils are also presented.
