“…This can be explained by the dissolution of Mn oxides with decreasing pH, which results in a greater bioavailability of Mn (Schachtschabel 1957). Our results suggest that the higher Mn content in beech leaf litter than ash leaf litter was influenced by the stronger soil acidification under beech.…”

“…Soil was extracted with 1 N NH4OAC and the exchangeable cations were determined by flame photometry (Ca, Na and K) and by atomic absorption spectrophotometry (Mg), respectively. Manganese was determined as 'active Mn' using the method of Schachtschabel (1957). Available Mo was extracted with 0.275 M ammonium oxalate (Haley and Melsted, 1957) and determined as described above.…”

Field experiments were conducted during the rainy seasons of 1989, 1990 and 1991 on an acid sandy soil in Niger, West Africa, to assess the effect of millet straw application (+CR) on growth and N 2 fixation of groundnut (Arachis hypogaea L.).Three years of +CR ( 4 t h a -1 yr -1) increased symbiotic N 2 fixation, total dry matter production (haulm plus pods) by 83% and total nitrogen (N) accumulation by 100%. Concentration of N in the shoot dry matter and total N in the soil were only slightly affected by the +CR treatment.Crop residue application increased the concentration of potassium (K) and molybdenum (Mo) and decreased the concentrations of aluminium (A1) and manganese (Mn) distinctly, both in the plant (shoot and nodule dry matter) and in the soil.The increase in dry matter production and N uptake was mainly due to improved N 2 fixation reflected by enhanced formation and growth of nodules as well as nitrogenase activity. This was attributed to improved chemical soil conditions, particularly to the higher availability of Mo and the lowered content of available AI and Mn.Although with the application of 4 t CR ha -I, 60 kg K were supplied, increased growth could not be attributed to the additional supply of K.

Abstract. White lupin (Lupinus albus L.) was grown for 13 weeks in a phosphorus (P) deficient calcareous soil (20% CaCO3, pH(H2O)7.5) which had been sterilized prior to planting and fertilized with nitrate as source of nitrogen. In response to P deficiency, proteoid roots developed which accounted for about 50% of the root dry weight. In the rhizosphere soil of the proteoid root zones, the pH dropped to 4.8 and abundant white precipitates became visible. X‐ray spectroscopy and chemical analysis showed that these precipitates consisted of calcium citrate. The amount of citrate released as root exudate by 13‐week‐old plants was about 1 g plant−1, representing about 23% of the total plant dry weight at harvest. In the rhizosphere soil of the proteoid root zones the concentrations of available P decreased and of available Fe, Mn and Zn increased. The strong acidification of the rhizosphere and the cation/anion uptake ratio of the plants strongly suggests that proteoid roots of white lupin excrete citric acid, rather than citrate, into the rhizosphere leading to intensive chemical extraction of a limited soil volume. In a calcareous soil, citric acid excretion leads to dissolution of CaCO3 and precipitation of calcium citrate in the zone of proteoid roots.
