“…Inasmuch as soil pH affects plant nutrition, it might be expected to affect the cation-anion balance of crops. The corn leaves analyzed in Experiment 8 were from plots that received different rates of ground limestone (Claassen, 1971). The data in Table 10 show that the highest limestone additions raised the pH of the surface 15 em of Nicollet loam from 5.95 to 7.60 and, of Fayette silt loam, from 5.67 to 7.77.…”

Plant species differ in their cation‐anion balance, but the organic anion content (C‐A), excess‐base (EB), and EB/N ratio of a given plant species may vary considerably when grown under different environmental conditions. Nitrogen fertilizers, for example, increase the organic anion content of certain crop plants and alter their effect on soil acidity by reducing the EB/N ratio. The primary objective of this study was to determine the effect of a wide range in amounts of P and K fertilizers and of soil pH on the cation‐anion balance of several crop species grown under field conditions. Leaf and plant samples of corn (Zea mays L.) and plant samples of alfalfa (Medicago sativa L.) and oats (Avena sativa L.) were taken for analysis from plots of several field experiments that had received a wide range in amounts of P and K or of ground limestone. In general, phosphorus and potassium fertilizers decreased the C‐A and EB contents of corn leaves, oats, and alfalfa. The effect of P and K additions in reducing C‐A and EB seemed less where they had the least effect in increasing crop yields; and in some experiments, K additions had little or no effect on C‐A, EB, or yield. Limestone additions on two soils, resulting in pH changes from below 6.0 to above 7.6, increased C‐A and EB of corn leaves slightly in one experiment, but had no significant influence on C‐A, EB, or yield in the other. Potassium fertilizers lowered the EB/N ratio of corn leaves. However, K and P fertilizers and limestone additions resulted in only very slight changes in the EB/N ratio of corn, oats, and alfalfa plants; and no change in EB/N was observed in several of the comparisons. Thus, on the basis of their effect on the EB/N ratio of the crops harvested, P and K fertilizers and soil pH should not alter the plant effect on the base status of soils.

“…They listed the benefits of liming as follows: it reduces soil acidity, increases availability of P and certain micronutrients, produces a more favorable soil environment for bacteria and other microorganism which speeds the decay of organic matter and release of N and P, increases the inoculation of legumes with N-fixing bacteria, improves calcium supply which is essential for plant growth, and reduces activity of elements such as aluminum and manganese which are toxic to plants. Further discus sions on the effects of liming and/or pH changes on the availability of individual nutrients and corn yield responses have been given by Claassen (1971).…”
