This chapter discusses various sources of nutrients to be applied to prevent soil nutrient depletion, as well as the optimum rates, times and methods of their application. It also describes how computer models can predict site-specific nutrient requirements and balanced fertilizer rates to maximi...
Nitrogen (N) fixation through legume-Rhizobium symbiosis is important for enhancing agricultural productivity and is therefore of great economic interest. Growing evidence indicates that other soil beneficial bacteria can positively affect symbiotic performance of rhizobia. Nodule endophytic plan...
