Effect of short-term supply of farmyard manure on maize growth and soil parameters in pot culture

“…In recent maize cultivation, organic manure has been widely used for its agronomical and environmental benefits [19], and it brings the maize yield close to its biological potential while reducing the input of chemical fertilizer [20]. Therefore, soil nutrients storage and crops uptake are enhanced by the additional organic manure input, subsequently ensuring a higher grain yield with less chemical fertilizer and environmental costs [18,21]. However, when additional organic manure is applied, how soil water and nutrients are transferred remains unclear in the semiarid region of northwestern China.…”

Long-term chemical fertilizer input causes soil organic matter losses, structural compaction, and changes in soil water and nutrient availability, which have been subdued in the most of dry farmland in China. The concept of "more efficiency with less fertilizer input" has been proposed and is urgently needed in current agriculture. Application of chemical fertilizer combined with organic manure (OM) could be a solution for soil protection and sustainable production of dry-land maize (Zea mays. L). Field research over three consecutive years on the Loess Plateau of China was conducted to evaluate the integrated effects of chemical fertilizer strategies and additional OM input on soil nutrients availability and water use in maize. The results showed that, after harvest, soil bulk density decreased significantly with OM application, concomitant with 11.9, 18.7 and 97.8% increases in topsoil total nitrogen, organic matter, and available phosphorus contents, respectively, compared with those under equal chemical NPK input. Water use in the 1.0-1.5 m soil profile was improved, therefore, the soil conditions were better for maize root growth, leaf area and shoot biomass of individual maize plants increased significantly with OM application. Optimized NPK strategies increased grain yield and water use efficiency by 18.5 and 20.6%, respectively, compared to only chemical NP input. Furthermore, additional OM input promoted yield and water use efficiency by 8.9 and 5.8%, respectively. Addition of OM promotes sustainable soil and maize grain productivity as well as friendly soil environmental management of dry land farming.

“…Organic fertilizers are recommended for their role in improving crop yields and sustaining soil health by recycling macro‐ and micronutrients (Akhtar et al., 2019; Aslam et al., 2010; Fernandez et al., 2016). For example, application of manures and straw mulch can significantly improve soil physico‐chemical and biological properties including soil structure and microbial abundance, activity and biomass, and increase soil fertility and productivity (Akhtar et al., 2018; Gangwar et al., 2006; Masood et al., 2014). Manures also improve soil physical properties by enhancing soil aggregate stability, volume of macro pores and saturated hydraulic conductivity (Agbede et al., 2008; Dhaliwal et al., 2019; Hati et al., 2006).…”

Biochar amendments offer promising potential to improve soil fertility, soil organic carbon (SOC) and crop yields; however, a limited research has explored these benefits of biochar in the arid and semi‐arid regions. This two‐year field study investigated the effects of Acacia tree biomass‐derived biochar, applied at 0 and 10 t ha‒1 rates with farmyard manure (FYM) or poultry manure (PM) and mineral phosphorus (P) fertilizer combinations (100 kg P ha‐1), on maize (Zea mays L.) productivity, P use efficiency (PUE) and farm profitability. The application of biochar with organic–inorganic P fertilizers significantly increased soil P and SOC contents than the sole organic or inorganic P fertilizers. Addition of biochar and PM as 100% P source resulted in the highest soil P (104% increase over control) and SOC contents (203% higher than control). However, maize productivity and PUE were significantly higher under balanced P fertilizer (50% organic + 50% mineral fertilizer) with biochar and the increase was 110%, 94% and 170% than 100%‐FYM, 100%‐PM and 100% mineral fertilizer, respectively. Maize productivity and yield correlated significantly positively with soil P and SOC contents These positive effects were possibly due to the ability of biochar to improve soil properties, P availability from organic–inorganic fertilizers and SOC which resulted in higher PUE and maize productivity. Despite the significant positive relationship of PUE with net economic returns, biochar incorporation with PM and mineral fertilizer combination was economically profitable, whereas FYM along biochar was not profitable due to short duration of the field experiments.
