Purpose Conservation tillage can significantly affect the biological, chemical, and physical properties of soil. This study aimed to determine the effect of conservation tillage on the soil microbial community and respiration and on soil CO 2 emissions. Materials and methods In this study, the effects of 10 years of conservation tillage (no-till: NT and ridge tillage: RT) on soil CO 2 fluxes and soil microbial communities were assessed in a black soil in Northeast China. Results and discussion The annual soil CO 2 emissions were higher under moldboard plow (MP) than under NT by 7.8 % (P<0.05). The average soil microbial respiration rate from RT was higher than that from MP by 11 % (P<0.05). Soil microbial respiration under NT (65 %) and RT (64 %) contributed more to soil CO 2 emissions than MP (54 %). Total soil bacterial and fungal phospholipid fatty acids (PLFAs) were 1.6 times and 2.6 times greater under NT and RT, respectively, than under MP in the 0-5 cm layer, whereas they decreased by 21-47 % under NT and 26-41 % under RT in the 5-10

“…It is desirable that the soil present a high cation exchange capacity, as it represents soil capacity to retain the elements necessary for plants. This parameter also indicates the soil potential to provide calcium, magnesium and potassium to plants [43]. In the present study, the samples showed a Journal of Agricultural Chemistry and Environment high cation exchange capacity, with an average value of 36.34 meq/100 g, and are hence considered as soil with great natural fertility [44].…”

The knowledge of the soil quality plays a vital role in the agricultural sector. Despite its importance, there is scarce scientific information concerning this regard. The objective of this research is to develop a methodology to identify and select the most appropriate indicators of Soil Quality Index (SQI) in a region with high agricultural activity. For its conformation, a descriptive statistical analysis and a Pearson correlation matrix were performed and the indicators that showed greater variation were identified using a Principal Components Analysis (PCA). A sensitivity analysis was carried out and the most sensible soil indicators of SQI were identified. This statistical procedure was also used to specify the weights of the indicators in SQI. The variables resulting from the multiparametric statistical analysis were pH, organic matter, sodium, calcium, iron, zinc, cation exchange capacity and electrical conductivity. The robustness of the SQI obtained in this study was demonstrated through simulations carried out by the numerical optimization through simplex method. The Soil Quality Index range obtained (0.54 -0.75) locates Culiacan Valley soils as moderate/high quality.

“…Conservation tillage can significantly affect the biological, chemical and physical properties of soil by reducing soil disturbance (Mellinger, ). The soil microbial communities are generally related to the soil organic matter (SOM) (Wu, Milner, Díaz‐Pérez, & Ji, ), soil nutrients (Allison & Martiny, ) and other properties such as pH and soil texture (Carson et al., ). Tillage and other management practices greatly affect soil organic carbon (SOC) and microbial biomass carbon (MBC) (Zhang, Liu, & Chen, ).…”

To assess changes in organic carbon pools, an incubation experiment was conducted under different temperatures and field moisture capacity (FMC) on a brown loam soil from three tillage practices used for 12 years: no‐till (NT), subsoiling (ST) and conventional tillage (CT). Total microbial respiration was measured for incubated soil with and without the input of straw. Results indicated that soil organic carbon (SOC) and microbial biomass carbon (MBC) under ST, NT and CT was higher in soil with straw input than that without, while the microbial quotient (MQ or MBC: SOC) and metabolic quotient (qCO2) content under CT followed the opposite trend. Lower temperature, lower moisture and with straw input contributed to the increases in SOC concentration, especially under NT and ST systems. The SOC concentrations under ST, with temperatures of 30 and 35°C after incubation at 55% FMC, were greater than those under CT by 28.4% and 30.6%, respectively. The increase in MBC was highest at 35°C for 55%, 65% and 75% FMC; in soil under ST, MBC was greater than that under CT by 199.3%, 50.7% and 23.8%, respectively. At 30°C, the lower qCO2 was obtained in soil incubated under NT and ST. The highest MQ among three tillage practices was measured under ST at 55% FMC, NT at 65% FMC and CT at 75% FMC with straw input. These data indicate the benefits of enhancing the MQ; the low FMC was beneficial to ST treatment. Under higher temperature and drought stress conditions, the adaptive capacity of ST and NT is better than that of CT.
