“…It suggests that Ks and Da were more suitable in TA than CA soil [27,39], and this study obtained similar data (Figures 5 and 6). However, corn grain yield did not significantly differ between CA and TA [63]. On the other hand, corn grain yield [81] and other crops [82] did not increase significantly when lime and dolomite were applied, probably because the reaction time of the liming agents in soil was much longer than in this study.…”

“…The low value of the TA soil Bd in the first layer could be explained by soil mechanical fracture due to tillage and reduction in soil total porosity [59,61,62] and by low clay content [27]. However, similar studies showed that at the transition beginning from TA to CA, soil Bd was not significantly different [15,29,61,[63][64][65]. In other studies, TA soil Bd was significantly higher than in CA soil, but only in soils with a high clay percentage [27].…”

Tillage conservation practices (CA), traditional agriculture (TA), and liming influence soil properties and crop yield. However, it is essential to demonstrate which tillage and liming practices improve soil properties and forage corn yield. This study compared soil properties and forage corn production in two tillage systems with the addition of dolomite and lime, which formed four treatments. The tillage in the first three days surpassed the TA soil CO2 emission, with 64.8% more CO2 than in the CA soil, and the TA hydraulic conductivity and bulk density were more suitable than those in the CA soil. The CA soil had 233 earthworms m−2 more than in TA. The TA green forage corn yielded 6.45 t ha−1 more than in CA, with a higher P, Ca, and Mg foliar content than in CA, but in the CA, the foliar N and K were higher than in TA. The liming increased soil cations (except K), highlighting the lime on dolomite with—52% Al and + 4.85 t ha−1 of forage corn compared to the control. Soil CO2 emission was far lower in CA than in TA, with a slightly lower forage yield, and other soil properties were improved, meaning lower land preparation costs and time savings than in TA. Lime improved acidic soil faster than dolomite, generating higher forage yields.

“…Al-Wazzan and Muhammad [1] found that no-tillage systems considerably lower soil bulk density while raising soil porosity and organic matter in contrast to conventional tillage systems. Similarly, According to Bai et al [2], for conventional tillage and no tillage treatments, the mean soil bulk density in the experimental site in November 2013 was 1.27 g cm −3 , with soil depths ranging from 0 to 30 cm. After a two-year trial with different tillage intensities, there was a little decrease in soil bulk density in the no-till plots with straw cover compared to conventional tillage.…”

Influence of Conservation Agriculture on Certain Soil Qualities Both Physical and Chemical in Relation to Sustainable Agriculture Practices a Review

Conventional tillage raises the possibility of soil erosion and degrades crucial physical characteristics of the soil, such as soil organic carbon (SOC) reduction. Additionally, ineffective management techniques result in a decrease in soil organic matter, a breakdown of the soil's structure, and more erosion. As a result, crop yields have decreased. Conservation agriculture (CA) is being considered as a potential system having the capability of improving soil quality and providing stable yields. This review's primary goal is to demonstrate how conservation agricultural practices affect certain physical and chemical characteristics of soil in order to support sustainable agriculture. So as to produce production system that are sustainable, conservation agriculture refers to cropping system management approaches that support permanent soil cover, low soil disturbance, and appropriate crop rotation. With the use of conservation agriculture techniques, it is possible to enhance the physical and structural health of the soil (by reducing bulk density and improving soil aggregation), in addition to increase soil water infiltration, decrease water runoff and soil loss, decrease evaporation loss, decrease soil organic carbon, and lower greenhouse gas emissions from agriculture. These factors are crucial for maintaining soil health and sustainable crop production. In general, applying the conservation agriculture concepts of limited tillage, soil cover, and legume integration would promote the development of soil microorganisms and organic matter by decreasing erosion. Conservation agriculture is therefore regarded as one of the agricultural systems that have the ability to favorably contribute to soil physical and chemical improvement as well as techniques for mitigating and adapting to climate change.

“…The plight of agricultural production in karst areas has been an important constraint on regional economic development, especially in southwest China (Bai et al, 2022). The fragile ecological environment has led to a severe shortage of arable land, forcing farmers to plant maize on marginal and sloping land (Gao et al, 2022), where severe soil erosion and nutrient leaching usually occur (Herout et al, 2018).…”

“…For example, many studies have shown that conservation tillage has no or even negative effects on maize yield (Peng et al, 2020;Zhang, K. P., et al, 2022a). In addition, many studies conducted in the karst areas focused only on the impact of tillage practices (Jia et al, 2019;Bai et al, 2022), ignoring the possible interactive effects with other factors, such as precipitation quantity and distribution (Zhang, Q., et al, 2022b), fertilization, crop type, and other agronomic practices (Wang et al, 2018).…”

To cope with the change of precipitation pattern, we explored the effects of conservation tillage and precipitation variability on soil moisture status and silage maize productivity, seeking solutions to improve the yield and quality of maize in the karst areas of China. In this study, precipitation variability and conservation tillage were jointly analyzed by precipitation levels (normal precipitation, 30% lower and 30% greater than normal precipitation), tillage methods (conventional tillage and no-tillage) and cover crop mulching (mulching and no mulching). It was found that no tillage (NT) increased the maize yield by 12.85% compared with the conventional tillage (CT) treatments. Above-normal precipitation treatments did not significantly increase biomass and soil water content across different fertility stages, but below-normal precipitation treatments reduced maize yield, crude protein (CP) content and soil water content at all soil levels. CT treatment significantly increased soil water content in the tillage layer (0–40 cm), but NT treatment significantly increased dry matter yield, plant height and CP content at harvest by 10.99, 3.41, 5.62%. Cover crop mulching significantly increased maize yield by 8.26% and soil moisture content at the seedling stage in 0–40 cm soil by 2.76 and 2.52%. The three-way interaction effects involving precipitation levels, tillage methods and cover crop mulching were significant for maize yield, CP content and soil water content (p < 0.05). In addition, this study found that soil water content was positively correlated with crude protein content of maize (p < 0.05). In conclusion, this study concluded that a combination of NT and cover crop mulching should be used to mitigate maize production risks caused by precipitation variability in the karst areas.
