tailieunhanh - Comparative study of soil nutrient status in three forest types of Dharmapuri forest circle, Tamil Nadu, south India

A study was carried out to investigate the comparative study of soil nutrient status such as soil chemical properties in different forest types of Dharmapuri forest circle of Tamil Nadu. Totally forty soil samples were collected from three forest types viz., Tropical dry deciduous forest, Tropical dry evergreen forest and Tropical dry thorn forest. The results revealed that nitrogen content was exhibited high (334 kgha-1 ) in Tropical dry deciduous forest due to a large extent on the amount and properties of organic matter in the forest floor for Nitrogen rich upper layers as compared to the lower layers. Available phosphorous content was recorded higher ( kgha-1 ) in soil of Tropical dry deciduous forest because phosphorus is the ore based mineral which has no influence by plant communities in that area and this might be the reason for higher phosphorus content forest soils. Similarly, tropical dry deciduous forest exhibited higher potassium content ( kgha-1 ) which may be attributed to the fact that most of the dry deciduous forest soils are rich in potassium due to presence of potassium containing minerals. | Comparative study of soil nutrient status in three forest types of Dharmapuri forest circle, Tamil Nadu, south India
