“…Maltas, Kebli, Oberholzer, Weisskopf, and Sinaj () examined soil pore characteristics in a 37‐year field experiment in Switzerland using organic and mineral fertilizers and found that organic management produced slightly better soil pore properties than mineral fertilization, and the pore size distribution was also altered. Similar results were obtained by Papadopoulos, Bird, Whitmore, and Mooney () with X‐ray computed tomography (CT) scanning in the UK. In addition, several researchers have examined the effect of organic fertilization on soil pores under other beneficial modes of tillage (Cogger, Bary, Myhre, Fortuna, & Collins, ; Loaiza Puerta, Pujol Pereira, Wittwer, van der Heijden, & Six, ).…”

Organic farming can potentially mitigate soil compaction, which commonly occurs in vegetable plantations, particularly in greenhouses when compared with open-air systems. Although several studies have addressed the effect of planting patterns on soil pore characteristics, few studies have focused on changes in pore attributes under organic fertilization. We used adjacent fields during green manure planting as a control to compare the differences in soil physicochemical and macropore parameters between 14-year-old greenhouse plots and open-air plots under organic fertilization. Pearson's correlation analysis was performed to analyse the drivers of soil macropore characteristics in vegetable plantations in Jiangsu Province, China. A significant increase in connectivity, fractal dimensions and total macroporosity and a decrease in bulk density after 14 years of organic farming, particularly in the surface layer in the greenhouse, were observed. However, the difference in pores in the plough pan layer was not significant between the treatments. The volume of small pores (50-500 μm) and medium pores (500-1,000 μm) increased significantly (p < 0.05) in both the greenhouse and open-air systems, showing significantly positive relationships with soil organic matter (SOM) and total nitrogen (TN) content. Large pores (>1,000 μm) showed a clear decrease, especially in open-air fields, possibly due to the disappearance of the original straw residues in the surface layer. Small and medium pores in the plough layer increased in greenhouse fields, whereas the opposite occurred in open-air fields. Overall, compared with open-air systems, long-term organic greenhouse patterns had a significantly positive effect on soil pore attributes.

“…Pore measurements performed by Papadopoulos et al. () in the UK under organic management also suggested that long‐term organic fertilization could increase the SOM content and pore size, and the effect might be both time and scale dependent.…”

“…Microbial biomass was also found to be significantly higher under organic than conventional management [118]. Other authors observed better structure and porosity in soils under OF than in conventionally cultivated soils in the UK, but this effect was found to be scale and time-dependent [153]. In a study evaluating the long-term effects of organic viticulture in France, the authors found that OF led to an increase in SOC, potassium content, soil microbial biomass, and nematode densities [154].…”

“…Despite the number of studies focused on the effect of organic and conventional farming practices on the chemical and biological properties, there is still no comparative research on soil physical properties under organic and conventional farming management (Papadopoulos et al, 2013). Similarly, research on cover crops has been confined to their use as nitrogen-binding agents and their effect on succeeding crops (Sainju et al, 2003), while relatively few studies on the effect of winter cover crops on soil physical properties under northern climate conditions have been conducted (Talgre et al, 2011).…”

A b s t r a c t. For testing how cover crops and different fertilization managements affect the soil physical properties in a plough based tillage system, a five-year crop rotation experiment (field pea, white potato, common barley undersown with red clover, red clover, and winter wheat) was set. The rotation was managed under four different farming systems: two conventional: with and without mineral fertilizers and two organic, both with winter cover crops (later ploughed and used as green manure) and one where cattle manure was added yearly. The measurements conducted were penetration resistance, soil water content, porosity, water permeability, and organic carbon. Yearly variations were linked to the number of tillage operations, and a cumulative effect of soil organic carbon in the soil as a result of the different fertilization amendments, organic or mineral. All the systems showed similar tendencies along the three years of study and differences were only found between the control and the other systems. Mineral fertilizers enhanced the overall physical soil conditions due to the higher yield in the system. In the organic systems, cover crops and cattle manure did not have a significant effect on soil physical properties in comparison with the conventional ones, which were kept bare during the winter period. The extra organic matter boosted the positive effect of crop rotation, but the higher number of tillage operations in both organic systems counteracted this effect to a greater or lesser extent.
