Long-term effects of different planting patterns on greenhouse soil micromorphological features in the North China Plain.

ABSTRACT: Soil structure represents a basis for soil water retention and fertiliser availability. Here, we performed a micromorphological analysis of thin soil sections to evaluate the effects of 10 years of organic planting (OPP), pollution-free planting (PFP), and conventional planting (CPP) on greenhouse soil structure in the North China Plain. We also analysed soil bulk density, soil organic matter (SOM), and wet aggregate stability. The CPP soil microstructure included weakly separated angular block or plate forms and weak development of soil pores (fissured or simply accumulated pores) with the highest bulk density (1.33 g cm^-3) and lowest SOM (26.76 g kg^-1). Unlike CPP, the OPP soil microstructure was characterised by highly separated granular and aggregated structures a
