“…Therefore, one of the various theories which have been formulated deals with the presence of high concentrations of soluble salts and lower oxides of manganese and aluminium in acid soils. Manganese toxicity has been recognized by numerous investigators (1,2,5,6,8,13,14,16,17,18,19) as one of the most important factors limiting the growth of some plant species, such as alfalfa, on acid soils.…”

Two groups of alfalfa varieties and crosses were grown in nutrient solutions containing two levels of manganese: 0.5 and 25 parts per million. Significant differences between varieties in their ability to tolerate manganese toxicity were observed. Promising individuals from the variety trial were selected for strain building. Some resulting crosses were found to be highly tolerant to the toxic level of manganese. This character appears to be inherited.

“…Calcium (14), P (18), and Mo (2) deficiencies have been implicated in poor growth of plants on acid soils. Manganese (4,6,9) and A1 (12,18) toxicity have also been cited as being responsible for poor plant growth on acid soils. Some investigators (10,11) have concluded that the primary benefit of liming acid soils is the reduced concentration of Mn and A1 in the soil solution.…”

Bush beans (Phaseolus vulgaris L.), carrots (Daucus carota L.), and lettuce (Lactuca sativa L.) were grown for 3 years on soils amended with S or lime and N fertilizer. Yields of all crops increased with lime application but response to N varied among crops and years. Lettuce head weight tended to increase with N application at pH greater than 6.0, but it decreased with N application at lower pH levels. A soil pH of 5.6 to 6.4 was optimal for carrots and beans, and of 6.1 to 6.6 for lettuce. Plant tissue K and Mg concentrations were not affected by soil pH or N rate. Phosphorus and Ca concentration of plant tissue generally increased with lime application. Plant tissue Zn and Mn concentration usually decreased with increasing soil pH between pH 5.1 and 6.4. The reduction in bean and lettuce leaf Mn concentration between pH 5.1 and 5.7 ranged from 30 to 71%. Low bean yields at pH 5.1 were possibly caused by a combination of Mn toxicity and P deficiency. Failure of lettuce to head at low pH may have been caused by Mn toxicity.

“…Research conducted in the early-to mid-20th century identified Mn toxicity as a cause of poor crop growth in acid soils (Funchess 1919;Bortner 1935;Hale and Heintze 1946;Löhnis 1951) amongst the other limiting factors of Al toxicity and deficiencies of Ca, Mg, P, and Mo. It is interesting that, in a number of these early studies, the soils had been acidified through the application nitrogenous fertiliser.…”

Frontispiece. Synchrotron-based micro X-ray fluorescence images of manganese (Mn), calcium (Ca), and zinc (Zn) distribution in trifoliate leaves of cowpea and soybean grown in complete nutrient solution with 30 µM Mn and in lower alternate leaves of sunflower and expanded leaves of white lupin at 400 µM Mn. In cowpea and soybean, the small red flecks indicate Mn accumulation in the apoplast, small green spots of Ca accumulation in vacuoles, small green angular spots of Ca oxalate, and the larger red and green areas of Mn and Ca accumulation associated with necrosis. Sunflower trichomes accumulate Mn and Ca. In white lupin, the yellow to orange spots indicate the accumulation of both Mn and Ca in vacuoles. The distance and colour scales apply to all images.
