Variation Characteristics of Particle Surface Electrochemical Properties during the Improvement of Reclaimed Soil from Hollow Village in Loess Area

Soil surface electrochemical properties, such as specific area and charge number, are important indexes to evaluate the agricultural soil quality change. However, there is not enough focus on effect of different improved materials reclaimed characteristics. Therefore, we selected maturing agent (TM), fly ash (TF), organic fertilizer (TO), + (TMO), (TFO), no modified material (CK) treatment for 5 years field location experiments study effects properties from abandoned homestead. The results showed that, compared with CK treatment, area, density increased 11.36–14.05 m2 g−1, 13.49–18.58 cmol kg−1, 1.14–1.76 C m−2 after five application materials, respectively, number under TFO, TMO, TO by 28.9%, 25.2%, 37.7% CK, respectively. Meanwhile, significantly (p < 0.05), showing an order TFO > TMO TF TM CK. electric strength can reach 108 V m−1. statistical analysis suggest that contents matter (SOM), silt, clay were positively correlated which main factors changes properties. Our research conclusion shows in process reclamation homestead Loess Plateau, helpful improve among organic–inorganic was a suitable improving fertility soil.
