A comparative study on cultivation and nutritional status of Oyster
Mushroom Pleurotus ostreatus on different substrates
Abstract :
Soil plays an important role in the global carbon cycle. It acts as both sink and source of carbon in the atmosphere depending on the land use system. The objective of the present study is to estimate the amount of carbon that can be sequestered in the forest soils of Ukhrul district in Manipur, North-east India. The samples were collected from the forest area ofMatiyang village situated in the eastern side of Ukhrul District, which is located near the Indo-Myanmar frontier. The soil samples (100 each) were collected at 0-15cm and 15-30cm depths. The samples were randomly collected from 100 pits of 30m x 30m x 30m and marked using Global Positioning System (GPS). The soil samples were then analysed for soil organic carbon content (SOC). The mean organic carbon content in the forest soil of the area was worked out taking into account all the 100 samples each from the two depths. For the purpose of statistical analysis, the area was categorised into three elevation - lower, middle and upper, and only 28 samples from each elevation was considered. The mean organic carbon content in the forest soil of the area is 2.93 and 2.04 at 0-15 cm and 15-30 cm respectively, while the organic carbon content in the soil at 0-30 cm is 2.48%. An independent samples t-test was conducted to compare the means of SOC between the two depths and between the three elevations. The results of this t-test revealed a significant difference (p0.05) in the mean of SOC% between the elevations suggesting that the amount of organic carbon is randomly distributed irrespective of the elevation.The data presented in the study indicates a fairly large amount of soil organic carbon present in this forest area.
