This comprehensive work explores various aspects of plant-soil interactions, focusing on carbon and nitrogen dynamics, nutrient uptake, and rhizosphere biology. It begins with an examination of carbon and nitrogen compounds from bio-waste composts and their significance for nitrogen supply. The distribution and transformation of labeled carbon in model plant systems are analyzed, highlighting the impact of dissolved humic substances. The text delves into plant uptake and utilization, featuring studies on the absorption of methyl-tert-butyl ether by spinach and radish, as well as the comparative uptake of copper, zinc, and cadmium by spinach roots under different nutrient applications. The relationship between shoot and root systems is addressed, discussing changes in root space due to logging and the effects of soil management on assimilate distribution. The biology of the rhizosphere is explored, including microbial biomass diversity in tropical crops and the use of denaturing gradient gel electrophoresis to assess microbial diversity. The text also discusses the breakdown of aromatic xenobiotics in the root zone and the selection of effective mycorrhizal fungi to enhance pine growth. Additionally, the work investigates rhizodeposition effects, including carbon deposition calculations in vegetable soils, bacterial colonization of rapeseed roots, and nitrogen transfer from alfalfa to associated grasses.
