Academic literature on the topic 'Purulia soil'

In an agrarian economy-dominated livelihood system, soil factor considered to be an essential determinant to prioritize the choice for crop selection and productivity. The laterite soil is formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods, which leads to leaching of soil, leaving only oxides of iron and aluminum. It lacks fertility due to a lower base-exchanging capacity and a lower content of nitrogen, phosphorus, and potassium. Laterite soil is found in the western plateau region (mainly found in the parts of Birbhum, Bardhaman, Bankura, Purulia, West Midnapore districts) of West Bengal. This soil is red in colour, acidic in nature (from 5.5 to 6.5 approx.) and poor in organic matter, calcium, phosphates and nitrogen. Overall, leaching under slight to very high soil erosion makes this soil infertile; though with proper irrigation facilities, scope of growing vegetation and cultivation can be possible in this soil. It has been observed that, Increase in yield of paddy with nitrogen is not significant in cultivation; but, when phosphate is added along with it high responses are obtained, indicating a typical phosphate deficient tract. The present paper tries to highlight on the factors responsible for the limited scope of agricultural productivity on lateritic tracts of West Bengal, which need to be addressed for effective land use planning and management in future.

Abstract Basic types of creation myth are treated here. The ex nihilo (from nothing) myth, for instance, emphasizes creation from the mind of the Creator (e.g., Yahweh/God/Allah) or creation from the words of the Creator (e.g., the Polynesian Io). The creation from chaos myth tells of creation from undifferentiated material such as cosmic eggs (e.g., the Dogon world egg). The world parents myth—creation from the sacrifice of the world parent(s) (e.g., the Chinese Pangu, the Indian Purusha, the Norse Ymir) often involves the separation of the two world parents, representing Earth and Heaven (e.g., the Polynesian Papa and Rangu, the Mesopotamian Apsu and Tiamat, the Egyptian Geb and Nut). In the earth diver myth an animal dives into the primordial waters to find soil that becomes Earth. This type is particularly prevalent among Native American tribes of the east (e.g., the Iroquoians). In the emergence-type myth, the people emerge from the World Mother (Earth). The birth metaphor is evident here. This myth type is almost exclusively southwestern Native American (e.g., Dine, Hopi) and in it goddesses play significant roles. The chapter undertakes to ask why we have creation myths. Why are they important for our sense of ourselves as cultures and as a species?
