Abstract

A study was conducted in Upper Yamuna Forests of Garhwal Himalayas to determine the humic and fulvic acid carbon status at different altitudes and seasons. The Humic and Fulvic acid carbon contents increased with increasing altitude.  Humic and Fulvic acid carbon showed highly significant positive correlation at all altitudes and seasons and significant negative correlation for soil depth.  In general, the soils at different altitudes are well supplied with humic and fulvic acid carbon, the most important component of healthy fertile soil. Humic and fulvic acid also play a vital role in the improved nutrient uptake of plants by acting like a carrier of nutrients and also by unlocking previously unattainable nutrients for the plants. Another important role of humic and fulvic acid is its ability to stimulate microbial activity in the soil. Humic and fulvic acid provides a necessary carbon based food source for which the microbes to thrive on. Soil microbes are also important in improving the structure of the soil. Soil microorganisms will break down organic matter in the soil, thus building more humus and adding to the porosity of the soil, which can aid in aeration and water retention. Humic and fulvic acid carbon associated with the soil of high altitudes is higher than at lower altitudes.  This may be low temperature conditions coupled with good hydrated environment which support to healthy growth of Abies pindrow- Picea smithiana and Quercus leucotrichophora- Q. floribunda oak forests at higher altitude.
