“…The traditional paddy field system in the Brazilian subtropics is based on intensive soil disturbance (SOSBAI, 2018), which results in high levels of soil degradation (Boeni et al., 2010). Alternatives, like the long‐term adoption of no‐tillage, have arisen as important tools to improve soil quality in the paddy fields (Denardin et al., 2019). However, we observed improvements in soil chemical attributes under ICLS in the short term.…”

“…Thus, current flooded rice cropping systems require higher fertilizer levels to sustain high yields (Boeni et al., 2010). On the other hand, soils managed under no‐tillage favor SOM accumulation and nutrients in the topsoil (Denardin et al., 2019; Feng et al., 2006; Tang et al., 2007) as well as better soil microbiological attributes (Gao et al., 2004; Martins et al., 2017).…”

“…Although the adoption of no‐tillage provides improvements in soil quality through the increase of SOM content, rice yield under no‐tillage requires 14 yr to surpass conventional tillage system yields (Denardin et al., 2019). Thus, the adoption of this practice alone does not increase rice crop yield, especially in the short term, and it is necessary to diversify the production system with other crops and/or activities (Denardin et al., 2019; Huang, Zhou, Cao, Xia, & Zou, 2015).…”

Integrated crop-livestock systems (ICLSs) appear as a good alternative to increase nutrient use efficiency (NUE) in rice (Oryza sativa L.) through the improvement in nutrient cycling and soil chemical attributes in paddy fields. The objective of this study was to evaluate the impact of an ICLS on soil chemical attributes and on the fertilization requirement of N, P, and K by flooded rice in the Brazilian subtropical region. Nutritional status, yield, and NUE of flooded rice were evaluated by fertilization trials through rice response to different fertilization rates of N, P, and K. Soil chemical attributes were evaluated at the beginning of the experiment and 30 mo later.Different fertilization rates were applied in two systems: (a) a conventional system (CS), based on intensive tillage, rice monocropping and winter fallow, and (b) ICLS, characterized by no-tillage and winter cattle grazing in annual ryegrass (Lolium multiflorum Lam.) pasture. Rice shoot accumulation of N, P, and K was greater under CS than ICLS at all fertilization levels. On the other hand, higher rice yields were observed under ICLS at almost every fertilization level, suggesting higher NUE than CS. In addition, rice yield was increased by 40% by fertilization of P and K under CS, whereas no response was observed under ICLS. These benefits were possibly related to greater nutrient cycling and greater synchronism between rice's nutrient uptake and nutrient release of the soil. Our results indicate that the adoption of ICLS ensures greater NUE becoming a system less dependent on external inputs.Abbreviations: CEC, cation exchange capacity; CS, conventional system; ICLS, integrated crop-livestock system; NUE, nutrient use efficiency; SOM, soil organic matter.

“…Also, greater soil aggregate stability and lower penetration resistance have been reported for no‐tillage soils relative to tilled soils . Although the adoption of no‐tillage has often been shown to raise the organic carbon content and lower the pH of a soil, significantly lower pH values have been also reported in conventional compared with no‐tillage systems . The main soil characteristics determining the influence of tillage practice on SOC (and indeed on other soil properties) are the texture and the initial SOC level .…”

BACKGROUND Irrigation and tillage systems alone or in combination with organic amendments can strongly influence soil properties, which in turn may also modify the environmental fate of any pesticides applied. This study was aimed at determining how amendment with composted olive‐mill waste (W) influenced leaching, sorption, and persistence of the herbicide clomazone in rice field soils under different tillage and irrigation management practices. The field trial conducted covered 3 years in succession, with six treatments: irrigation by sprinkler and conventional tillage without (ST) or with W application (80 Mg ha−1) (STW), irrigation by sprinkler but no tillage (SNT), irrigation by sprinkler but no tillage with W application (SNTW), and continuous flooding irrigation and tillage without (FT) and with W application (FTW). RESULTS Application of W significantly increased the adsorption of clomazone to soil in the first and third years. In the first year, the persistence of clomazone under aerobic (t1/2 = 33.1–36.3 days) and anaerobic incubation conditions (t1/2 = 3.43–10.8 days) decreased after W application to t1/2 values in the ranges 18.1–29.7 and 3.06–5.44 days, respectively. However, in the third year, although clomazone persistence increased significantly in SNT and ST when W was applied under both incubation conditions, it decreased significantly in FT management under anaerobic incubation conditions. The addition of W led to less leaching of clomazone, particularly for the FT case where the herbicide leaching losses were 2.8 and 2.6 times lower in the first and third years after W addition, respectively. CONCLUSIONS Using W as an organic amendment could be regarded as an invaluable strategy to reduce water contamination by clomazone in rice production, especially under traditional tillage and flooding management. © 2019 Society of Chemical Industry

Strategic tillage (ST) has been proposed to maintain the benefits and alleviate the negative effects of long‐term no‐till (NT) management. In this study, the effects of ST on soil properties and yield loss were evaluated for a double‐cropped rice (Oryza sativa L.) paddy from 2006 to 2017 in Southern China. Three tillage systems were investigated: long‐term NT, continuous rotary tillage (RT), and ST. The results showed that ST effectively solved the problem of long‐term NT management: low and unstable bulk density in the soil surface layer. Compared with NT, ST significantly increased the available P (AP) concentration, available K (AK) concentration, the AP storage by 16.55% and the AK storage by 21.37% in the upper 20 cm soil. Moreover, the soil pH for NT and ST was lower than RT. ST increased the acidification risk in the 0–5 cm soil layer (pH was 4.84 in 2017) but significantly reduced the risk of yield loss compared to continuous NT. The average yield gap between ST and NT ranged from 408.21 kg ha−1 (during 2006–2009) to 1,144.85 kg ha−1 (during 2014–2017). ST reduced soil organic carbon (SOC) and total nitrogen (TN) concentration compared to NT in the 0–5 cm soil layer. However, it did not affect SOC and TN storage, although light fraction organic carbon (LOC) storage for ST was 36.59% lower than that for NT. ST is a promising option for promoting and maintaining the sustainability of rice production in Southern China.
