“…Martínez et al (2016) reported that the soil pore system exhibited slightly higher specific diffusivity in the topsoil of mouldboard ploughing than in NT. Sağlam et al (2015) also reported that for heavy clayey soils, reduced tillage practices that included ploughing improved physical soil qualities for root development and water movement. It is believed that the inconsistent results arise from differences in climate, soil type and soil moisture level between humid and semi-arid regions.…”

SUMMARYCrops often experience combined soil stresses. Root responses to soil penetration resistance (PR) and drought stress can be an important basis for crop management. In 2013/14, a 2-year experiment was conducted to evaluate the effect of tillage treatment and drought stress (no irrigation for 4, 12 and 20 days during the V10–V16 growth stage) on the root length, diameter, cortex and cortical cell, and grain yield of maize (Zea mays L.) in a clayey red soil in southern China. Total root length and average root diameter were significantly correlated with soil PR and moisture. The cortical cell file number increased with soil PR and drought stress, while cortical cell size increased only with soil PR. Soil PR and moisture played different roles in maize root morphology modifications, but were both affected by tillage practices. Deep ploughing and conventional tillage increased soil moisture under severe drought stress conditions, whereas soil compaction and no-till significantly increased soil PR. The results indicate that high PR in clayey red soil was responsible for a decrease in maize root size and grain yield under drought conditions.

“…However, these current measures mainly focus on the optimization of fertilization methods, the selection of soil mineral modifiers and land consolidation to improve newly reclaimed cultivated land soil quality. Tillage treatment is a traditional soil improvement method, which can significantly regulate the dynamic balance of water, fertilizer, gas and heat in the soil 12 . It also affects the structural stability of the soil and the absorption of nutrients by crops, and finally affects crop yield 13 .…”

Tillage treatments have an important effect on soil microstructure characteristics, water thermal properties and nutrients, but little is known in the newly reclaimed cultivated land. For the reason, a long-term field study was to evaluate the tillage effects on soil physicochemical properties and crop yield in newly reclaimed cultivated land via the macroscopic and microscopic analysis. Three tillage treatments were tested: continuous conventional moldboard plow tillage (CT), sub-soiling/moldboard-tillage/sub-soiling tillage (ST) and no-tillage/sub-soiling/no-tillage (NT). Under CT, the microstructure was dominated by weakly separated plates structure and showed highest bulk density (BD) (1.49 g cm−3) and lowest soil organic matter (SOM) (3.68 g kg−1). In addition, CT reduced the capacity of soil moisture retention and temperature maintenance, resulting in aggregate structure deterioration and fragility. Unlike CT, the soil was characterized by moderately separated granular structure and highly separated aggregate structure under conservation tillage practice of ST and NT. NT was associated with the highest soil moisture content (20.42%), highest quantity of macroaggregates (> 0.25 mm) by wet-sieving (34.07%), and highest SOM (6.48 g kg−1) in the surface layer. Besides, NT was better able to regulate soil temperature and improved the values of geometric mean diameter. Under NT and ST, a stable soil structure with compound aggregates and pores was formed, and the maize yield was increased by 12.9% and 14.9% compared with CT, up to 8512.6 kg ha−1 and 8740.9 kg ha−1, respectively. These results demonstrated the positive effects of NT and ST on soil quality and crop yield in newly reclaimed cultivated land.

“…As an important crop management practice, tillage has manifold influences on both the soil and crops, which are subjected to the local climate, soil type, soil water status, and tillage time (Sağlam et al, 2014). In order to balance the effect of different tillage practices, occasional tillage, also termed as "one-time tillage", has been evaluated as a potential tillage practice (Nunes et al, 2015;Blanco-Canqui and Wortmann, 2020).…”

Effects of tillage alteration on soil water content, maize crop water potential and grain yield under subtropical humid climate conditions

Ab s t r a c t. Seasonal drought stress is common in farmland even under humid climate conditions. Low soil water content and high penetration resistance in clayey soil are both factors that limit crop growth, which is significantly affected by tillage. In a twoyear (2014)(2015) field experiment conducted in Hubei, China, the effects of conventional tillage, along with occasional deep tillage and no-till, on the soil water content and penetration resistance values of red soil and on the crop water potentials of the maize crop (Zea mays L.) were tested. Compared to conventional tillage, deep tillage reduced the difference in the soil water characteristic curve between 0-40 cm soil layers, resulting in a more loose and homogeneous topsoil. The deep tillage significantly (p<0.05) decreased soil penetration resistance, increased soil-available water content and soil water content during the dry period, promoted an increase in maize root density by 11.4~31.6%, and increased the water potential of the maize root and leaf during most growth stages. In contrast, the effect of no-till was opposite to that of deep tillage, reducing maize grain yield by 25.3~26.3%. The results confirmed that no-till is not appropriate for the clayey red soil but rather that tillage is needed. This suggests that occasional deep tillage is helpful in mitigating seasonal crop drought stress under the conditions of a humid climate.
