Résumé partiel
An investigation was carried out to study the distribution of available primary and secondary nutrients in soil profiles of mango orchards of Latur district. Total 10 soil profiles at five different spacings were selected for this experiment. From each soil profile 6 soil samples (0-15, 15-30, 30-45, 45- 60, 60-75, 75-90 em depth) were collected and analyzed for available primary and secondary nutrients. The results obtained from this investigation evaluated that the soil pH, EC, organic carbon and CaC03 of these soils ranged between 8 to 8.5, 0.09 to 0.16 dSm-I, 0.38 to 0.77 per cent and 41 to 177 g kg-1 with mean value of 8.25, 0.13 dSm-1 , 0.58 per cent, 86.50 g kg-1 , respectively. Further it was found that organic carbon content of these soils were decreased with increasing in depth while pH and CaC03 content increased with decreasing in depth. In case of soil EC no proper trend was observed. The data evaluated that mango orchard soils were medium in organic carbon and calcareous in nature.
