Dissemination pattern of available nutrients and biological properties of soil under sugarcane–wheat cropping system

A field experiment was conducted during the Kharif and Rabi seasons of 2001-2005 in regular crop sequence at Crop Research Station, Nawabganj, CSA University of Agriculture & Technology, Kanpur in order to find out the effect of farm yard manure (FYM) and NPK levels in rice-wheat cropping system. One level of FYM (10 t ha-1) and one level of N (120 kg ha-1),three levels of P (0, 30, 60 kg ha-1), four levels of K (0, 30, 60, 90 kg ha-1) were tested. The grain yield of rice and wheat crops were increased at levels of FYM (10 t ha-1) and NPK (120, 60, 60 kg h a-1). The application of FYM with 120 kg N, 60 kg P O and 60 kg K O ha-1 gave significantly highest yield of rice and wheat crops. The 2 5 2 application of NPK fertilizers with FYM were found increased in their uptake. The application of NPK fertilizers with FYM was found improvements in physio-chemical properties of soil like soil ph, organic carbon and available NPK.

Properties Of Soil

In this review article the usage of waste sewage sludge and the biomass ash for improving the engineering and non-engineering properties’ of both concrete and soil are discussed in detail. Numerous past research works were studied in detail so as to predict the behavior of biomass ash and waste sewage sludge when used for the stabilization process of soil and concrete. Past studies related to the usage of stabilized sewage sludge and biomass ash were studied in a detailed manner and depending upon the past studies several conclusions has been drawn which are discussed further. Several studies related to the usage of the waste sewage sludge for improving soil physical, chemical and biological properties showed that the usage of waste sewage sludge improve the physical properties, chemical properties, macro-nutriential properties and micro-nutriential properties up to a great extent. Depending upon the results of the past studies it can be concluded that the usage of sewage sludge has positive impact over all the properties of soil and this waste should be utilized in improving the properties of soil rather than dumping. Numerous studies related to the usage of the biomass ash showed that biomass ash has positive impact over both soil as well as concrete. Studies related to the usage of the biomass ash in soil showed that there was a positive response of the stabilized soil after its stabilization with the biomass ash. Studies related to the usage of the biomass ash in concrete showed that the biomass ash can be used up to 10 percent replacement of the ordinary Portland cement so as to attain maximum strength results from it.
