“…The statistical tests for confirming MDS include, amongst others, PCA and varimax rotation followed by simple linear regression (Juhos et al 2016), cluster analysis (Dilly et al 2018) and correlation, PCA and discriminant function analysis (DFA) (Juhos et al 2019). For SQI evaluation, some previous work has used either ANOVA or MANOVA to test associations between SQIs and soil management groups (de Andrade Barbosa et al 2019; de Paul Obade and Lal 2016; Kiani et al 2017;Molaeinasab et al 2018;Nakajima et al 2015).…”

“…The stability of soil aggregate is an important indicator of the soil degradation vulnerability and soil structure in semiarid grasslands, and reflects the fertility of the soil, which plays a primary role in sustaining its porosity, transport of nutrients, and water and gas contents (Adesodun et al, 2007; Fan et al, 2021; D. Liu et al, 2021). The water stability of soil aggregate has also been quantified using the wet sieving method according to the geometric mean diameter (GMD), mean weight diameter (MWD), and water‐stable aggregates (WSA) (Cheng et al, 2015; Molaeinasab et al, 2018). Some studies have reported that nutrients addition can influence the soil aggregate formation and stability by altering the soil organic matter (SOM) components and contents (Chang et al, 2019; Guo et al, 2022).…”

Nitrogen and phosphorus can influence the stability of soil organic matter (SOM) and aggregate, which are important for ecosystem functions. However, understanding remains limited regarding the impact of nutrient addition on soil aggregate stability, aggregate‐relevant organic matter and nutrients in desert steppe. Here, we studied the variation of soil aggregate stability, nutrients, and the exchangeable cations distribution characteristics, and the chemical composition and thermal stability of SOM were analyzed using thermogravimetric (TG) and Fourier transformed infrared spectroscopy. Samples of soil were collected under four conditions, phosphorus addition (P), nitrogen addition (N), combined phosphorus and nitrogen addition (NP), and no addition (CK), from 0 to 10 cm depth over 4‐year experiments in desert steppe in northern China. The percentage of micro‐aggregates (0.25–0.053 mm) and large macroaggregates (>2 mm) dramatically increased by 34.2% and 18.1%, respectively, under the N treatment condition compared to the CK treatment, and micro‐aggregate content significantly increased under the P treatment, respectively. Nitrogen addition significantly increased the soil aggregate stability index, but the P addition reduced their value. The both macro‐aggregates (>0.25 mm) and silt‐clay (<0.053 mm) were preferentially enriched with soil nutrients and the exchangeable cations. The N and P addition was beneficial to nutrients accumulating in macro‐aggregates, and enhanced the aliphatic‐C and aromatic‐C abundances respectively. The TG‐T50 value (i.e., temperature when 50% of SOM is lost) increased after nutrient addition, indicating that the SOM has higher thermal stability, especially in the micro‐aggregates. The addition of N may have potentially a greater influence on aggregate stability through their influence exchangeable polyvalent cations (Ca2+ and Mg2+), and stability of SOM was influenced by chemical composition and exchangeable K+, Na+, Ca2+ contents in desert steppe. Overall, nutrient addition effects stability of SOM and aggregate by altering chemical composition and exchangeable cations in desert steppe in northern China.

“…Numerous studies have shown that soil quality has suffered significant degradation worldwide as a result of anthropogenic disturbances due to land‐use change (Afanador‐Barajas et al, 2020; Andrews et al, 2003; Baranian Kabir, Bashari, Bassiri, & Mosaddeghi, 2020; de Lima, Hoogmoed, & Brussaard, 2008; Molaeinasab, Bashari, Tarkesh Esfahani, & Mosaddeghi, 2018; Safaei, Bashari, Mosaddeghi, & Jafari, 2019; Viana et al, 2014; Zhang et al, 2019) and natural processes (Peng et al, 2013; Pla, 2010; Zhang et al, 2019). However, under the conditions of the Ecuadorian Amazon, very few studies have been carried out to assess the impact of the change from forest to agricultural and livestock systems upon soil quality.…”

Few studies have comprehensively evaluated the effect of changing land use on the soil quality in the Ecuadorian Amazon region that is subject to continued deforestation processes. This study evaluated the influence of different types of land use on soil quality using an integrated soil quality index (SQI) with a minimum set of indicators, based on 140 soil samples from 7 land use types, in seven productive distinct landscapes in Pastaza Province, Ecuador. The land use type evaluated was Chakra_A, Chakra_B, Chakra_C, Cattle_A, Cattle_B, Cattle_C, and Forest. Land use type had significant effects on soil properties and thus on soil quality. SQI was developed by using, AP, Zn, TOC, BD, and LL; AP and Zn had highest weighting values (0.38), which indicated that these indicators contributed the most to final SQI. In general, the SQI varied significantly depending on the type of land use and two groups were established: the first categorized as of moderate quality with mean SQI values of 0.45, 0.44, and 0.41 for Chakra_A, Forest and Chakra_B, respectively; while the second group registered average SQI values of 0.33, 0.33, 0.32, and 0.30 for Chakra_C, Cattle_C, Cattle_A and Cattle_B, respectively, considered of low quality. The methods used are applicable to the study of changes in soil properties as functions of agroforestry systems, which are generated by changes in land use in similar landscape of the Ecuadorian Amazon.
