“…Although the cropping system did not display a significant effect on soil acidity, a slightly higher pH in KCl value was determined in the ICS (7.24) compared to CCS (7.13). Our findings are consistent with those of other long-term tillage experiments on silty loam Chernozem [37] and with global meta analyses [38]. The higher organic matter content in CCS is related to the accumulation of plant residues and higher organic acid content [15].…”

Tillage methods and intensity can be used as means of improving macronutrient and trace element concentration in soil and crops. A two-year field experiment was conducted to examine the impact of two cropping systems—intensive (ICS) and conservation (CCS), on the macro- and microelements in the soil and their accumulation in the grain of two cultivars of winter wheat. The experiment was conducted in a randomized complete block design with three replications of each tillage treatment. The results showed that the content of available N (0.7 kg ha−1) and organic matter (0.04%) slightly increased in CCS compared to ICS. The concentrations of Ca, K, and S macroelements and microelements such asBa, Cr, Hg, and Sr in the soil were significantly higher in CCS than in ICS. Higher concentrations of macroelements K and P, microelements such asFe, Zn, and As, and the greater value of the bioaccumulation factor for elements essential to humans such as P, Cu, Fe, and Zn, were also found in CCS compared to ICS. On the other hand, wheat cultivars grown in ICS were more efficient at accumulating macroelements and some trace elements than ones grown in CCS. While it is not without challenges, the conservation cropping system could represent an important part of the long-term strategy to sustainably improve soil fertility and the nutritional quality of the wheat grain.

“…The results of soil pH and TN were consistent with that reported by Neugschwandtner et al . (2020) that observed no significant difference in soil pH and TN after 15 years of different crop rotation managements. However, salt levels in the soil were decreased over time.…”

Increasing crop diversity has been highly recommended because of its environmental and economic benefits. However, the impacts of crop diversity on soil properties are not well documented. Thus, the present study was conducted to assess the impacts of crop diversity on selected soil quality indicators. The cropping systems investigated here included wheat (Triticum aestivum L.) grown continuously for 5 years as mono-cropping (MC), and a 5-year cropping sequence [(wheat–cover crop (CC)–corn (Zea mays L.)–pea (Pisum sativum L.) and barley (Hordeum vulgare L.)–sunflower (Helianthus annuus L.)]. Each crop was present every year. This study was conducted in the northern Great Plains of North America, and soil quality data were collected for 2016 and 2017. Selected soil quality indicators that include: soil pH, organic carbon (SOC), cold water-extractable C (CWC) and N (CWN), hot water-extractable C (HWC) and N (HWN), microbial biomass carbon (MBC), bulk density (BD), water retention (SWR), wet soil aggregate stability (WAS), and urease and β-glucoside enzyme activity were measured after the completion of 5-year rotation cycle and the following year. Crop diversity did not affect soil pH, CWC, CWN, HWC, HWN and SWR. Cropping systems that contained CC increased SOC at shallow depths compared to the systems that did not have CC. Crop diversity increased WAS, MBC, and urease and β-glucoside enzyme activity compared with the MC. Comparison of electrical conductivity (EC) measured in this study to the baseline values at the research site prior to the establishment of treatments revealed that crop rotation decreased EC over time. Results indicate that crop diversity can improve soil quality, thus promoting sustainable agriculture.

“…Some authors (Ferreira et al, 2020) note that prolonged use of No-till increased the content of organic carbon particles, mineral-bound organic substances and humic as a result of the constant flow of plant residues into the surface layers, which contributed to the increase in physical and chemical aggregation of the soil and the increase in its water content. Compared to other systems, No-till increased the electrical conductivity, cation exchange capacity, total nitrogen and total organic carbon in the uppermost soil layer (Neugschwandtner et al, 2020).…”

Agriculture is one of the leading branches of the economy in the Republic of Bashkortostan (Russia). Long-term agricultural use of land with the use of plowing has led to a decrease in the thickness of humus-accumulation horizon of soils, reduction of organic matter and nutrients. There is also a deterioration in water-physical properties, the development of water and wind erosion, and a decrease in productivity. Recently, the use of soil conservation farming systems has started, including the use of No-till system. This study presents the results of assessment of physical properties of agrochernozems under conditions of No-ill use. The physical properties of the soil, such as bulk density, humidity, temperature, structural and aggregate composition, were studied using methods and tools accepted in soil science. It is shown that in the upper soil layer (0-20 cm) there is an accumulation of soil moisture, the values of capillary and total moisture capacity, as well as bulk density are approach to the values of nature soil and are optimal for the growth and development of agricultural crops. Structural and aggregate composition is characterized by excellent aggregate state with their excessively high resistance to damaging effects of water. However, in a single case, the soil density increases to a depth of 45 cm. This fact was caused by the impact of heavy agricultural machinery. The declining of soil density can be achieved by treating it with a special bioorganic agent and growing perennial grasses.
