| Fazit: Es gibt einen Austausch bzw. Kreislauf von Aminosäuren und Proteinen zwischen dem Boden, Pflanzen und der Atmosphäre. Blütenpollen dominieren im Frühling die Proteingehalte in den erdnahnen Luftschichten, während in der übrigen Jahreszeit Böden und Pflanzen die Hauptquellen zu sein scheinen. Aminosäuren und Proteine der erdnahen Luftschichten werden durch Tau und Regen auf die Pflanzen und die Böden wieder niedergeschlagen. In der Luft werden sie von Mensch und Tiereingeatmet oder über die Schleimhäute aufgenommen. In einem Ökosystem besteht ein Stoffaustausch über die erdnahen Luftschichten zwischen den einzelnen Kompartimenten, über deren Bedeutung für Mensch, Tier und Pflanzenwachstum wir noch sehr wenig wissen. |

| At two sites in the Armenhof district, 10 km east of Fulda, Germany, dew samples were collected from June 1996 to June 1997 and investigated for free and protein bound amino acids. On account of the high pollen content, at the beginning of June 1996 and in May 1997 total amino acid concentrations were 53 – 390 µmol/l, in one sample 922 µmol/l. At other times the concentration in dew was 8 to 164 µmol/l. On 4 and 5 June 96 the diluted free amino acid fraction (DFAA) of the total hydrolyzed amino acids (THAA) at both sites amounted to 35 – 44% and was predominantly arginine, proline and glutamine/glutamate. Likewise on 11th of March 97 the fraction of DFAA was found to be 39.5% with extremely high arginine and proline fractions. At other times the... |

| We hydrolysed (6 M HC1) soll organic matter (SOM) from mineral top-soil horizons, litter, and the fraction rendered extractable by 0.5 M K2SO4 after Chloroform fumigation from eight soils under arable, grassland and forest use. covering a wide ränge of site conditions. Our aims were to quantify amino acid contents in the hydrolysate derived from whole soil. litter and soil microbial biomass, respectively. We also wanted to test if the pattern of hydrolysable amino acids of the whole soil is uniform irrespective of site conditions and land use. and if there i s a relation with the amino acid pattern of the respective soil microbial Community. The content of hydrolysable amino acids in the whole soil was higher in the soil samples from grassland and forest... |

| Commencing in 1980, a long-term experiment is carried out to compare mineral fertilizers (MIN), composted manure (CM) and composted manure with application of biodynamic preparations (CMBD) at three different fertilizer application rates. With mineral fertilizer the lowest contents of 0.80% C and 0.069% N, with manure 0.90% C and 0.080% N, and with manure and biodynamic preparations 1.08% C and 0.094% N were achieved in the topsoil. 42.9 to 53.7% of Nt was bound in 18 protein amino acids including asparagine and glutamine. Amino acid contents in the hydrolysates of the topsoil were significantly different according to fertilizer type: MIN < CM < CMBD. The higher contents in manure fertilized plots were observed even at the lowest rate of fertilizer... |
