Abstract

The present study was conducted to evaluate the Rating Scale of Pedological Development in Humid Moisture Regime of Guava Growing Soils in North-East Region of Haryana during 2021-23. For this fifteen representative pedons were excavated from five districts (Ambala, Yamunanagar, Karnal, Kurukshetra, and Kaithal). The morphological characteristics of all the pedons under study were examined in situ in the field and horizon-wise soil samples were collected to analyze for chemical characteristics in the laboratory at Department of Soil Science CCS HAU, Hisar. To evaluate pedological development of soil pedons two modified rating scales i.e. , Relative Horizon Distinctness (RHD) and Relative Profile Development (RPD) were used. The results obtained from all soil pedons were found to have RHD and RPD ratings varying from 0-10 & 3-11, 0-15 & 0-19 for two geomorphic units i.e., recent and old alluvial plains, respectively. The data of field morphology rating scale indicated development of Guava Growing Soils in humid moisture regime pedologically to the order of old alluvial plains >recent alluvial plains. Application of these rating scale and suggested modification on some soils of North-East Haryana, achieved the chronosequence, as well as, the diagnostic horizons of soils which belong to Inceptisols and Alfisols order have higher values of RPD than the soils belong to Entisols orders. So, the rating scale can be used for comparing the development of soils pedologically in humid climatic regimes.
