Abstract:
Agriculture has been the backbone of the Indian economy. In India around 70 per cent of the population earns its livelihood from agriculture. It fulfils the basic need of human beings and animals. It is an important source of raw materials for many agro-based industries. All chemical properties of the soil are the key factor of soil fertility. Different chemical properties in soil viz., N, P, K, EC pH affect due to the application of chemical fertilizers and organic manures. However the magnitudes of the impact at 0-15 and 15-30 cm soil depth are varies and alterations in the chemical properties of soil are not well defined. Therefore, the present trial was conducted on long term impacts of organic manures and chemical fertilizers on different chemical properties of a Tarai soil at the N.E. Borelog crop research centre, GB Pant University of Agriculture and Technology Pantnagar, Uttarakhand (India). The experiments plot comprising of six treatments were laid out in simple randomized block design with four replications. Treatments were i. Control, ii. 100% NPK (LTFE), iii. 100% NPK + FYM (LTFE), fallow field, poplar based agro-forestry system and eucalyptus based agro-forestry system. The pH of the soil was not significantly influenced by different treatments in both the surface and sub surface soil. The highest EC at surface and sub surface soil was found in poplar based agroforestry systems (T5), followed by eucalyptus based agroforestry systems (T6), 100% RD of NPK+FYM @ 15 t ha-1(T3) and lowest EC was recorded in the control plot (T1). The highest soil available nitrogen in surface soil was observed in 100% NPK + FYM @ 15 t ha-1 treated plot (T3), followed by T5 and T4 whereas, the lowest value was observed in control plot. The data obtained from this experiment enhanced the understanding of long term impacts of organic manures and chemical fertilizers on different chemical properties of soil in the Tarai region soil of UK in India.
