“…On Oxisols, therefore, crops such as corn which are not sensitive to manganese toxicity can produce high yields with less lime than required on Ultisols which have high exchangeable aluminum content at low pH's. Such is not the case with tobacco and coffee which are sensitive to high manganese levels in the soil as shown by Abruña et al (3,5).…”

“…Abrufia et al (3) reported that intensively managed coffee responded strongly to liming on acid soils high in manganese but did well at very high acidity and exchangeable aluminum levels in soils low in manganese. Abrufia et al (5) found that tobacco responded strongly to liming on 3 Ultisols and an Oxisol and that response was closely related to the exchangeable aluminum and manganese content of the soils. limestone were added as required to provide a wide range in soil acidity and percent base saturation.…”

The effect of soil acidity factors was determined on yields and foliar composition of corn grown on Ultisols and Oxisols typical of the Humid Tropics. Soil pH values increased from about 3.8 with a base saturation of around 20 percent to about pH 5 with a base saturation of around 70 percent based on cation exchange capacities determined with neutral ammonium acetate. The low pH values in relation to exchangeable base contents are explained by the presence of free salts. The level of aluminum saturation of the soil based on exchange capacities as determined with ammonium acetate decreased from 40-percent at about pH 3.9 to 0 at about pH 5.2. The Ultisols had a high content of exchangeable aluminum when acid but the more weathered Oxisols contained little aluminum. A very close relationship exists between exchangeable base (Ca + Mg) and aluminum values based on total exchange capacities determined either with ammonium acetate at pH 7.0 or by the sum of cations at a given pH permitting conversion of one value to another. Corn responded strongly to liming particularly on the Ultisols which had high exchangeable aluminum content when acid. Calcium content of the corn leaves increased with soil base content and with yields but foliar composition was not otherwise affected by liming. Corn yields increased with pH to about 5.2 at which pH level these soils contained essentially no exchangeable aluminum, with exchangeable base content as determined with ammonium acetate to about the 70-percent saturation level, and with decreasing exchangeable aluminum in the soil to essentially 0. Soil pH, exchangeable base, and exchangeable aluminum content were effective criteria for liming these soils.

The effect of soil acidity factors on yields and foliar composition of intensively managed green beans was determined in Ultisols and an Oxisol typical of the Humid Tropics. Beans responded very strongly to liming on all six soils. Calcium content of the bean leaves increased and manganese content decreased with increasing lime rates and with yields. Bean yields increased with increasing soil pH to about 5.2 at which level these soils contained essentially no exchangeable aluminum. Bean yields increased with increasing exchangeable soil base content to about 70-percent saturation based on cation exchange capacities as determined with ammonium acetate at pH 7. Bean yields increased with decreasing exchangeable soil aluminum to essentially 0. Soil pH and exchangeable base and aluminum contents were effective criteria for liming these soils.
