Influence of straw mulch and no-tillage on soil respiration, its components and economic benefit in a Chinese wheat–maize cropping system

Effect of Precipitation Variation on Soil Respiration in Rain-Fed Winter Wheat Systems on the Loess Plateau, China

“…Similar to the pattern of seasonal average R s , the cumulative CO 2 emissions during the winter wheat whole growth period were 406.37, 372.58, and 383.59 g C m −2 under the three precipitation treatments, respectively ( Table 1 ), which is consistent with the study of irrigation gradient in Northwest China (cumulative CO 2 emissions ranged from 335 to 448 g C m −2 season −1 ) [ 36 ], but lower than the study in the North China Plain (cumulative CO 2 emissions ranged from 548.0 to 979.2 g C m −2 season −1 ) [ 37 ]. These differences may be due to the higher average annual temperature and rainfall in the North China Plain than in the Loess Plateau.…”

Soil type and integrated nitrogen nutrient-rice straw residue management techniques affect soil microbes, enzyme activities and yield of wheat crop

“…The soil microbial populations were recorded to be maximum in the zero tillage (T2) main treatment and nitrophosphate (NT7) sub-treatment except significantly lower count of fungi in NT7 as compared to other N-fertilizer combinations. It can be argued that similar to previously published reports, the zero tillage treatment provided the conducive optimum temperatures and retained more moisture helping in the proper growth and proliferation of the soil microbes as a result of the mulching effect of straw retained on the soil surface [ 38 , 39 ]. The application of nitrophosphate was beneficial as it released both the N and P nutrients in a slow-release manner that helped in sustained growth of the heterotrophic bacterial communities.…”

Analysis of small-scale soil CO2 fluxes in an orange orchard under irrigation and soil conservative practices

“…Several authors have explored the role of soil CO 2 flux under different agriculture practices. As example [ 78 ], suggested that the influence of SM (no-till versus tillage) on soil CO 2 fluxes is significantly different as function of the soil and agrometeorological conditions [ 79 ] reported that the use of organic mulching improves crop yields, with economic benefit in average up to 13.5 %, and increases the soil CO 2 activity in average of 24 %. Herein, ad-hoc low-cost accumulation chambers were used to identify the environmental impact of different conservative agricultural practices in terms of CO 2 emissions within a two-year study period (Dec. 2021–Dec.…”
