Agricultural practices can directly affect soil environmental conditions and consequently soil ecosystems and fertility. Soils under different agricultural practices like tillage and grazing were studied and compared to other soils affected by wildfire and different ages of abandonment. Atmospheric CO2, soil C-CO2 loss, soil temperature, soil moisture, bulk density, soil organic carbon (SOC), total nitrogen (TN), total phosphorus (TP), Redfield ratios of C:N:P, easily exactable and total glomalin-related soil protein (GRSPEE and GRSPT), and morphology, quantity, and stability of soil aggregates (WSA) were seasonally analyzed. Statistical significance checked using the two-factor ANOVA. Intense tillage and wildfire occurrence revealed a deficiency in soil nutrients and fertility more than grazing practices. Steady soil fertility conditions occurred in soils preserved by fire and ancient abandonment. The GRSP seasonal means varied significantly among all soils because of land-use effects. GRSPT, SOC, TN, and TP increased from winter to spring and reached the highest values in summer then decreased again in autumn. GRSP was positively correlated (P |
