“…This may be because biochar has much porous structure and higher adsorption capacity for inorganic nutrients than straw, which provides a suitable habitat for soil microorganisms 46,49 . In contrast, some reports found a decrease in microbial activity after biochar application 47,50 . These contrasting results could be related to changes in soil moisture, pH, and nutrient dynamics caused by the chemical components of the straw used.…”

“…Soil microbial biomass, as a living part of soil organic matter (SOM), drives SOM mineralization and nutrient recycling 45 . Both the biochar and straw application affect soil microbial activities through changing the habitats of soil microbes, availability of nutrients, and soil physical properties 46,47 .

Applying biochar to soil has been proposed as a strategy to enhance soil quality and crop productivity. To further evaluate the influence of biochar and straw application on soil fertility and crop yield, a five-year fixed site field experiment was conducted in a paddy field in Northeast China. The experimental design included six treatments: control (CK), biochar (C), straw (S), chemical fertilizers (NPK), biochar with chemical fertilizer (CNPK) and straw with chemical fertilizer (SNPK). The results showed that compared with the NPK treatment, CNPK and SNPK significantly increased soil total porosity, soil air permeability coefficient, soil organic carbon (SOC), C/N ratio, soil microbial biomass carbon (SMBC)‚ soil microbial biomass nitrogen (SMBN), invertase activity and rice yield. Furthermore, amendment of biochar had a better effect on SOC, C/N ratio, SMBC, and SMBN than that of straw. In addition, SMBC, SOC, and total nitrogen (TN) had significant correlations with soil enzyme activities. Therefore, amendment of biochar with chemical fertilizer is an effective measure to improve rice production and soil quality in the northeast of China.

“…Being a kind of green feedstuff, L. multiflorum is used in fresh, hay and silage forms. Planting L. multiflorum in fallow fields has proved a success, by simultaneously increasing grass yields and improving soil structure (Li et al 2008, Li et al 2011). Therefore, it is possible to plant L. multiflorum to feed ducks in a rice-duck farming system.…”

Rice-duck farming is a sustainable food system that provides rice and duck meat and eggs. Excessive application of commercial feedstuff for ducks weakens the sustainability of rice-duck farming. This study aims to investigate green forage ( Lolium multiflorum Lam.) as a substitute for commercial grain mix, to attain a maximum economic benefit and pollution-free production in rice-duck farming. The effects of a mixed feedstuff of green forage and commercial grain mix with a stable ratio of 1:4 (MFSR), mixture feedstuff of green forage and commercial grain mix with dynamic ratios (MFDR), and full commercial grain mix (FCGM) were studied. Results showed that Cherry Volley and hybrid ducks were more adaptable to mixed feedstuff than Mud ducks. Growth of ducks was classified into rapid, slow and steady-growth stages. The weight, body length, neck length, and chest circumference of ducks that were fed MFDR were only slightly decreased. The carcass weight, eviscerated weight, and semi-eviscerated weight of ducks fed MFDR were similar to those fed FCGM. MFDR significantly decreased duck fat accumulation. MFDR did not have negative impacts on the 728 B. Zhao et al. agronomic traits of rice yields. Duck profits per 667 m 2 were calculated as CNY (Chinese Yuan) 254.91 (MFSR), CNY309.27 (MFDR), and CNY39.36 (FCGM). MFDR effectively improved the rice-duck farming.

“…Soil science is considering a comprehensive assessment of soil quality for better decision making. The type of cropping system (monoculture, co-culture, or rotation) and the management regime (e.g., chemical vs. organic fertilization, irrigation, and tillage) can affect soil properties and microbial processes (Juhos, Czigány, Madarász, & Ladányi, 2019;Li et al, 2011;Nunes, van Es, Schindelbeck, Ristow, & Ryan, 2018;Olsson & Falkengren-Grerup, 2000). Differences in the distribution and quantity of litter inputs to the soil may affect the rate of organic matter (OM) degradation (Yavitt, Wright, & Wieder, 2004), soil enzyme activity (Baležentienė & Klimas, 2009;Yu, Ding, Luo, Donnison, & Zhang, 2012), and drive nutrient cycles, generally affecting soil fertility properties (Kaur, Sharma, & Puri, 2013;Peng et al, 2020).…”

A good bioindicator of soil health is one that perceives minor changes due to changes in soil management and leads to changes in the processes of the soil ecosystem. The aim was to evaluate the use of soil bioindicators in the determination of the utility of two different Cedrela odorata forestry management systems. The litter and soil samples were collected from the rhizosphere of a monoculture (with no fertilization nor irrigation), and a co-culture (with fertilization and irrigation) stand with Citrus latifolia. The soil and litter bioindicators measured were the activity of acetylesterase (FDA), acid phosphatase (AcPh), alkaline phosphatase (AlkPh), laccase, and the estimation of the potential net rate of carbon mineralization (PNRCM). The results indicated that soil enzyme activities (FDA and phosphatases) in the litter were sensitive to the different management system treatments. Enzymatic activity, per unit dry weight, was higher in litter of co-culture (FDA = 1.05 nkat g-1 AcPh = 1.33 nkat g-1; AlkPh = 03.0 nkat g-1) than in litter of monoculture (FDA = 0.617nkat g-1; AcPh = 0.40 nkat g-1; AlkPh = 0. 983 nkat g-1). Differences in soil total nitrogen content, organic matter (OM) content, and micronutrients were found. In general, the co-culture stand (with fertilization and irrigation) with C. latifolia showed the best results.
