“…Results obtained in northern and midwestern areas indicate that element concentration is influenced by environmental factors such as fertility, rate of seeding, and rotation (4,8,10,16,17). Tisdale and Nelson (18) have reported that certain factors known to influence the conversion of soil and added K to less-available forms are (i) type of colloid, (ii) temperature, (iii) wetting and drying, and (iv) soil pH.…”

An understanding of soil‐plant relationships, plant nutrition, and fertilization requires a knowledge of the variability of the chemical composition and uptake of elements by plants. The availability of certain elements is related to soil pH and since many of the soils of the southeastern U. S. are acid, particularly in the subsoil, additional information is needed on the effects of soil pH on the growth, chemical composition, and uptake of elements by maize (Zea mays L.). Greenhouse experiments were conducted on Greendale silt loam to investigate the effects of three soil pH levels, 3.9, 5.1, and 6.1, on the yield and certain chemical characteristics of selected maize inbreds and single crosses. Adequate plant nutrients were applied to all pots and two rates of dolomitic limestone were applied to increase the pH. Plants were harvested 36 days after planting, dried, and later analyzed for P, K, Ca, Mg, and Na. Highly significant differences in yields; P, K, Ca, and Mg concentrations; and uptake among maize entries were observed. Response of entries at different pH levels was not consistent for either uptake or concentration of P, K, Ca, or Mg. There were no significant differences in Na concentrations among entries or pH levels.

“…The severity of bacterial spot, caused by Xanthomonas campestris pv. vesicatoria in pepper (Jones et al 1983) and the incidence of leaf spot, caused by Cochliobolus heterostrophus in maize (Taylor 1952) increased as the foliar concentration of Mg increased. Panicle blast resistance in rice was positively correlated with the high foliar Mg concentration (Filippi and Prabhu 1998).…”

This study investigated the effect of magnesium (Mg) on sheath blight, caused by Rhizoctonia solani, development on rice plants from cultivars BR-IRGA 409 and Labelle grown in nutrient solution containing 0.062, 0.125, 0.25 and 0.50 mM of Mg. Sheath blight progress on inoculated sheaths was evaluated by measuring lesions expansion (mm) at 24, 48, 72 and 96 h after inoculation. Data were used to calculate the area under lesion expansion progress curve (AULEPC). The relationship between the foliar Mg concentration and the Mg rates was quadratic. The Mg concentration on leaf sheaths tissue was highest at the Mg rates of 0.389 and 0.400 mM, respectively, for cultivars BR-IRGA 409 and Labelle. A linear model best described the relationship between the AULEPC and the Mg rates. The AULEPC decreased by 48.7 and 26.2% for plants of cultivars BR-IRGA 409 and Labelle, respectively, as the Mg rates in the nutrient solution increased. The results permitted to conclude that high foliar Mg concentration played a pivotal role to decrease sheath blight lesions expansion.

“…Taylor (15) and Gorsline and co-workers (5) reported relationships between specific element concentration and leaf blight severity. Sayre (14) reported differences among inbred lines of corn in concentration of N, P, K, Ca, Mg, Cu, B, Al, Fe, Si, and Co. Gorsline et al (2,3,4) reported evidence for the heritability of element concentration in the ear leaf for Sr, Ca, Mg, K, P, Zn, Cu, B, Al, and Fe.…”

An understanding of liming, fertilization, plant nutrition, and soil‐plant relationships requires a knowledge of the variability of element accumulation within the plant. The availability of micronutrients is related to soil pH. Except for Mo, the availability of micronutrients is believed to increase with increased acidity. Since many of the soils in the southeastern U. S. are acid, particularly the subsoil, additional information is needed on the growth, concentration, and uptake of elements by maize (Zea mays L.) as affected by soil pH. Selected maize inbreds and single crosses were grown in the greenhouse on Greendale silt loam that had been adjusted to pH levels of 3.9, 5.1, and 6.1 with appropriate amounts of pulverized dolomitic limestone. Adequate plant nutrients were applied. Maize was harvested 36 days after planting; dried; and later analyzed for Cu, B, Zn, Mn, Mo, Al, and Fe. Entries differed significantly in concentration of each analyzed element at one or more pH levels, thus showing differential absorption of specific elements at various pH levels. Soil pH had a highly significant effect on the concentration of all elements studied except Fe. The entry × pH interactions were significant only for B and Al concentrations. Entries differed in the uptake of all elements studied. Uptake of all elements except B was affected by pH, and entry × pH interactions were significant for each of the elements considered.
