    Micromorphology of the Rhizosphere with Focus on Plant Nutrition
    Author(s): Dr. A. N. Sarkar*

    The paper highlights the historic background of Rhizosphere investigations focusing on Root- Soil Interface activities in terms of micro-morphology, using advanced micro-morphological investigation techniques and tools such as high-resolution microscope, scanning electron microscope, electron-probe micro-analyser analysis, X-Ray Diffraction Technique, Thin Micro- Autoradiography using Kodak thin myler films onto thin sections with optical polish < 1.0 micron. The details of the research findings are summarized in the relevant sections of the paper. The second part of the paper refers to a number of factorial pot experiments with French beans (Phaseolus vulgaris L) as test crop, involving three nitrogen sources (viz. ammonium phosphate, choline phosphate and calcium chloride) at 2 N levels (500 ppm n and 1000 ppm N), 2 initial soil pH levels adjus..
