dcterms:description "Pore size distribution and soil fertility A contribution concerning the physical classifikation of soils at soil maps Testing the physical classification of soils at soil maps pore size distribution of 17 well drained soils was measured. The results obtained for the 0–100 cm soil depth were correlated to land values as given in the „Reichsbodenschätzung”︁. Statistical evaluation of the data gave the following results: 1) Negative correlation (r = −0,11) between pore space pF 1,8–2, 9 and soil fertility. 2) Moderate correlation (r = 0,54) between pore space pF 1,8–4, 2. 3) Very close correlation (r = 0,95) between pore space pF 2,5–4, 2 and pF 2,9–4,2, respectively, and soil fertility. 4) Fair correlation (r = 0,76) between pore space pF > 4,2 and soil fertility. Therefore soil fertility is strongly dependent on physical factors related to pore size distribution and concerning water and N‐economy of soils. In our humid climate the factor N‐economy obviously has a stronger bearing on soil fertility than the factor soil water. The results make it possible to classify the soils in relation to N‐economy and water supply using the same index of pore size distribution. With the pore space pF 2,5–4,2, fertility and filter properties of soils are comprehended in the best manner. The terminus „Kapillare Sorptionskapazität”︁ is proposed to define both the factors. Finally some consequences are mentioned concerning plant nutrition and N‐fertilizing in regard to the physical factors of soil fertility."@de;
