“…With several factors interacting and crop yields varying from year to year under the influence of meteorological factors, it is difficult to objectively evaluate the effectiveness of soil tillage methods [74] or other factors involved when using technology. Wang et al [75] found that, although unconventional soil tillage systems do not play a significant role in improving yield, the benefits of the systems on soil health are still evident [76][77][78]. Optimal temperature ratios and water availability allow for the maximum yield to be obtained.…”

Maize (Zea mays L.) is one of the main agricultural crops grown worldwide under very diverse climate and soil conditions. For maize cultivation in a conventional tillage system, autumn plowing is a mandatory condition. Minimum soil tillage or no tillage has been applied in recent years, both in research and in production, for reasons relating to soil conservation and fuel economy. This paper presents the results of the research executed under pedoclimatic conditions at the Agricultural Research and Development Station Turda (ARDS Turda, Romania; chernozem soil) regarding the behavior of the maize hybrid Turda 332 cultivated in four tillage systems and two levels of fertilization during the period of 2016–2022. The following soil tillage systems were applied: a conventional tillage system (CT) and unconventional tillage systems in three variants—a minimum tillage system with a chisel (MTC), a minimum tillage system with a disk (MTD), and a no-tillage system (NT). They were applied with two levels of fertilization: basic fertilization (350 kg ha−1 NPK 16:16:16, applied at sowing) and optimized fertilization (350 kg ha−1 NPK 16:16:16 applied at sowing + 150 kg ha−1 calcium ammonium nitrate with additional fertilization in the phenophase of the maize with 6–7 leaves). The results highlight the fact that under the conditions of chernozem soils with a high clay content (41% clay content), maize does not lend itself to cultivation in MTD and NT, requiring deeper mobilization, with the yield data confirming this fact. This is because under the agrotechnical conditions for sowing carried out in MTD and NT, the seeder used (Maschio Gaspardo MT 6R) does not allow for the high-quality sowing of maize, especially under dry soil conditions. Instead, the MTC system could be an alternative to the conventional tillage system, with the yield difference being below 100 kg ha−1.

“…Furthermore, it was determined in previous studies that incorporating straw mulching with these tillage practices had multiple benefits. It improved soil quality and nutrients while also significantly reducing surface runoff volume [10][11][12]. This effect was particularly noticeable when tillage practices were combined with straw mulching, resulting in decreased outflow concentrations and reduced volumes of large-size colloids in surface and subsurface runoff.…”

Under three rainfall intensities (60–90–120 mm/h) and four tillage practices (longitudinal ridge tillage, cross ridge tillage, flat tillage and hole sowing), field experiments was conducted during the podding stage of peanuts to investigate the changes in hydrodynamic parameters and the erosion response on purple soil slope cropland in order to reveal the soil and water conservation benefits of different tillage practices. The results showed that: (1) The sediment yield of the four tillage practices was ranked in descending order: longitudinal ridge tillage, flat tillage, hole sowing, and cross ridge tillage. Under the same rainfall intensity, there were no significant differences in runoff among these four tillage practices (p > 0.05), whereas sediment yield varied significantly. (2) The average flow velocity, Reynolds number, and Froude number of each treatment were positively correlated with rainfall intensity, while the resistance coefficient was negatively correlated. Flat tillage and cross ridge tillage were intermediate. The Reynolds number and Froude number of each treatment did not exceed the critical value and were generally within the laminar flow range, except for the longitudinal ridge tillage treatment at 120 mm/h rainfall intensity. (3) The sediment yield intensity on the slope was negatively correlated with the resistance coefficient, following a power function. The runoff shear stress and runoff power on each treatment were both positively correlated with sediment yield intensity in a linear manner. Compared to longitudinal ridge tillage, the other three tillage practices showed much better soil and water conservation benefits. Among them, cross ridge tillage exhibited the best water storage and soil conservation effects. In terms of hydraulics, longitudinal ridge tillage and flat tillage increased the erosive force required for sediment initiation and suppressed erosion occurrence. The research results were of great significance in revealing the characteristics of runoff erosion in purple soil areas and controlling tillage practices for soil erosion in purple soil areas.

Arthropods play a crucial role in ecological processes and agricultural productivity. Soil physicochemical properties, indicators of soil health, are closely linked to arthropod communities. Gravel-sand mulching, commonly employed in arid farming, initially enhances water retention and temperature regulation but may contribute to land degradation with prolonged use. This study investigated how varying tillage durations affected soil properties and arthropod diversity under gravel-sand mulching. The analysis employed multiple comparison methods, covariance analysis (ANCOVA), non-metric multidimensional scaling (NMDS), and redundancy analysis (RDA). The results indicated that while soil fertility was better preserved in cultivated fields compared to in the desert grassland, arthropod diversity significantly decreased with longer cultivation periods. A total of 1099 arthropods from 79 species were sampled, by Barber trap. The highest diversity was observed in native grassland (NG), with 305 arthropods from 39 species, while tillage 21 years (GPS-21Y) exhibited the lowest diversity, with only 103 arthropods from 6 species. Dominant species included the carnivores Labidura japonica and Cataglyphis aenes. The analysis revealed low similarity in arthropod communities between GPS-21Y and other fields and high similarity in soil physicochemical properties between NG and the transition zone (STZ). RDA showed available potassium (APP) was negatively correlated with arthropod species diversity and concentration, total Nitrogen (TN) was positively correlated with arthropod species diversity but negatively correlated with species concentration, total phosphorus (TP) was negatively correlated with arthropod species diversity and concentration. This study provides insights into the relationship between maintaining soil fertility and supporting arthropod diversity in grassland agriculture. While soil fertility and arthropod diversity were correlated, continuous cropping practices negatively impacted arthropod diversity, offering valuable information for pest management and sustainable agricultural practices.
