Characterization of the iron status in plant parts and its relation to soil pH on acid soils

Effects of sodium fertiliser on the distribution of trace elements, toxic metals and water-soluble carbohydrates in grass and clover fractions

“…Other natrophilic species tend to have higher iron concentrations in the leaves. 22 Fleming 23 reported copper, manganese, iron and molybdenum to be greater in the leaves than in the stems or in¯orescences of different grass species and red clover. The distribution of iron and molybdenum between the different fractions in the present investigation con®rms this pattern, but casts doubt on whether copper and manganese are greater in herbage leaves or stems.…”

Soil‐Fertility Principles for Warm‐Season Perennial Forages and Sustainable Pasture Production

“…Nitrogen, P, and K fertilization efficiency is also increased when the soil pH is adequate (F. Adams and Martin, 1984). However, at high soil pH (>6.5), micronutrients become less available: with the exception of Mo, micronutrient availability decreases as soil pH increases (Corey and Schulte, 1973; Gupta, 1992). Therefore, it is important that adequate amounts of lime are applied to the soil to increase the pH to a desirable range but not such excessive amounts as to cause nutrient unbalances and micronutrient deficiency.…”
