dc.description.abstract | The influence of 30 years of cropping with different fertilizer and farmyard manure (FYM) inputs on the contents and depth distribution of organic C, total N (Nt), soil mineralizable N, and organic and inorganic N fractions was investigated in an Eutrochrept. Continuous application of 100 %NPK( + S), 150 %NPK( + S), and 100 %NPK( + S) + FYM led to a marked increase in organic C, total N, hydrolyzable N (viz., amino acid N, hydrolyzable NH4-N, hexose amine N, and unidentified hydrolyzable N), and nonhydrolyzable N as compared to an adjacent fallow. The contents of the various organic N fractions were largest in surface soil and thereafter decreased with the depth. However, at 30 – 45 cm depth the content of organic C was not affected by the different treatments except 100 %NPK( + S) + FYM. On the other hand, continuous cropping without fertilization resulted in a depletion of total hydrolyzable N in control over fallow by 27.2 % (0–15 cm), 19.6 % (15–30 cm), and 4.7 % (30–45 cm). The incorporation of FYM with 100 %NPK( + S) resulted in greater contents of soil mineralizable N as compared to 100 %NPK( + S) (0–15, 15–30 cm). The proportion of hydrolyzable N (57–76 % of Nt) decreased and that of nonhydrolyzable N (22–40 % of Nt) increased with depth. The proportion of amino acid N (19–26 % of Nt), hexose amine N (2.1–3.5 % of Nt) and unidentified hydrolyzable N (17–27 % of Nt) decreased with depth. All organic soil N fractions including even nonhydrolyzable N in surface and subsurface soils were highly significantly correlated with soil mineralizable N derived from incubations under waterlogged and aerobic conditions. The best correlation to mineralizable N was found for amino acid N and the least significant correlation for nonhydrolyzable N. | en_US |
