Scientific agricultural illustration, soil cross-section, highly realistic and professional style (not cartoon), clean infographic design for agronomy brochure. Show two comparative zones in the same soil profile (no split cartoon style, smooth transition): LEFT SIDE (phosphorus fixation): – Negatively charged phosphorus ions (P⁻) being strongly adsorbed by positively charged المعادن (Fe³⁺, Al³⁺, Ca²⁺) attached to clay particles – Represent electrostatic attraction with subtle arrows – Phosphorus becoming unavailable (fixed in soil matrix) – Dense clay minerals and oxide surfaces (iron/aluminum oxides) RIGHT SIDE (Fosbio technology – protected phosphorus): – Phosphorus surrounded by organic molecular structures (humic and fulvic acids) forming a protective layer – Representation of anionic polymers creating electrostatic repulsion barrier – Reduced interaction with Fe, Al, Ca – Phosphorus remaining mobile in soil solution – Gradual movement toward plant roots ROOT ZONE (important focus): – Detailed realistic plant roots (no cartoon) – Active rhizosphere with soil microbiology (bacteria, fungi, actinomycetes) interacting with roots – Microorganisms aiding phosphorus availability (subtle, scientific depiction) – Arrows showing phosphorus uptake by roots STYLE: – Realistic textures (soil, minerals, roots) – Neutral earthy color palette (brown, ochre, dark green) – Minimalistic, technical infographic style – No exaggerated characters or cartoon microbes – No glossy or artifi
