“…Wang et al (2019) reported a significant impact of nitrogen (N) application depth on root surface area and root volume in the 0-100 cm soil layers, with a noticeable decrease as the N depth increased. In addition, Niedziński et al (2023) indicated that deep N fertilization conditions led to an increase in crop root biomass and nutrient accumulation.…”

Background No-tillage of summer maize after the harvest of winter wheat is the primary agricultural practice on the North China Plain. However, prolonged no-tillage without deep tillage practices negatively impacts soil properties, which is detrimental to the growth and yield of summer maize. Methods Xianyu 688 and Jifeng 2 were used as test materials, no-tillage and surface fertilizing with normal N (BC240), no-tillage and surface fertilizing with N reduction (BC180), subsoiling layered fertilization with normal N (FC240) were designed, and subsoiling layered fertilization with N reduction (FC180), assess root distribution, dry matter accumulation, N absorption and utilization, and grain yield of summer maize. Results The FC240 and FC180 treatments significantly reduced soil bulk density in the 10-50 cm depth soil layer compared to the BC240 and BC180 treatments, and also increased total N content in the 20-50 cm depth soil layer. Root length in the 20-40 cm soil layer significantly increased with the FC240 treatment, along with a notable increase in root exudates, which improved root vitality during later growth stages. Additionally, the FC240 and FC180 treatments enhanced plant dry matter accumulation, N accumulation, and grain yield. Xianyu 688 exhibited increased N uptake efficiency, N fertilizer partial factor productivity, and N harvest index, while Jifeng 2 showed increased N uptake efficiency and N fertilizer partial factor productivity. Conclusion It provided useful enlightenment for selecting suitable maize varieties, formulating effective management strategies and cultivating high N-efficient varieties under the condition of subsoiling combine with layered N application.

“…This is because the slow distribution of nutrients from slow-release fertilizers, combined with their deep placement, creates nitrogen and phosphorus deficiency conditions in the topsoil at the beginning of the plant growing season. Niedzinski et al [35] observed that slow-release fertilizer deep placement led to an increase in root length, accompanied by a decrease in root weight in favor of tuber yield increase. However, the results of the conducted field experiment, as shown in Table 2, indicate that the effect of fertilizer deep placement on potato tuber yields was relatively limited.…”

Despite the notable decline in potato cultivation areas across Poland and Europe, potatoes remain a crucial crop with diverse applications. Achieving the ambitious emission targets set by the EU for agricultural production may be easier with the practice of deep placement of slow-release fertilizers, which may increase yields and reduce greenhouse gas emissions. To examine the effect of deep placement of slow-release fertilizers on potato tuber yields, plant nutrient uptake, nutrient use efficiency, and soil N2O-N emissions, a two-year field experiment was conducted on loamy sand soil classified as Alblic Podzol (Ochric) soil, under temperate climate conditions prevailing in central Poland. The experiment involved a three-field rotation (potatoes, wheat, and peas), with potatoes being cultivated after peas in both years of the study. The experiment compared the effects of applying slow-release fertilizer at soil depths of 10 and 20 cm (DP10 and DP20) to fertilization with single-nutrient fertilizers applied to the soil surface (TD). The experiment utilized increasing doses of nitrogen and phosphorus, denoted as D0 (control), D1, D2, and D3, along with a standard dose of potassium across all tested fertilizer application methods. The results of this study confirmed that deep placement of slow-release fertilizers had limited effects on potato tuber yields. Deep placement of slow-release fertilizer increased plant nitrogen uptake by 2.8–13.5% compared to topdressing. Consequently, there was an improvement in nitrogen use efficiency from 29.8–75.0% on sites with fertilizer topdressing to 38.7–89.8% on sites with slow-release fertilizer deep placement. Phosphorus uptake by plants on sites with slow-release fertilizer deep placement was approximately 9.3–13.0% higher than on sites with fertilizer topdressing. This led to an enhancement in phosphorus use efficiency from about 15.1–19.5% on fertilizer topdressing sites to 19.4–25.4% on slow-release fertilizer deep placement sites. The impact of fertilizer deep placement was found to be less pronounced compared to the effects observed with increased nitrogen and phosphorus doses. The most important factors affecting tuber yield and nutrient use in potatoes were rainfall levels during the growing season. Deep fertilization did contribute to reduce soil N2O emissions by about 14%. However, further research involving different fertilization methods is needed to comprehensively assess the effectiveness of this practice in reducing greenhouse gas emissions.

“…Therefore, it promoted the growth, dry matter accumulation and distribution of summer maize, increased seed nitrogen and improved seed yield [5][6] . NIEDZIŃSKI T et al 7 the results showed that when the fertilization depth was 20 cm, the absorption of nitrogen and phosphorus by potato increased by 20%, and the proportion of nitrogen accumulated in tubers increased by 21%. Additionally, the length of the plant and total root area were positively affected, and these were optimal for the distribution of dry matter, nutrients, and root development parameters.…”

It was to investigate the effects of different fertilizer formulation and fertilizer depth treatments on sugarcane (Saccharum spp. Hybrids.) yield, quality traits, soil enzyme activities, and overall soil fertility. The field micro-area experiment was conducted in Baise City, Guangxi Province. The sugarcane treatments were applied with different formulations of nitrogen, phosphorus and potassium and different fertilization depths. The soil fertility level of different fertilization treatments was comprehensively scored by principal component analysis and fuzzy mathematics. In comparison to conventional fertilization, the D15 treatment for optimized fertilization rate at 15 cm depth demonstrated enhanced sugarcane height and sugar content. Additionally, the total seedling weight increased by 35.26%. Furthermore, the inter-root soil contents of urease, sucrase, catalase, and acid phosphatase exhibited a significant increase by 75.37%, 50.94%, 4.87%, and 24.56%. The nitrogen content of sugarcane stems was increased by 52.24%. The nitrogen and potassium contents of sugarcane stems exhibited a notable increase in the T2 treatment, when compared to the other treatments, reaching 1.835 g/kg and 8.111 g/kg, respectively. The combined soil fertility of the T4 and D15 treatments was moderate, and exhibited an upward trend when compared to the low soil fertility observed in the T0 conventional fertilization treatment. 1In conclusion, the fertilizer optimization ratio of nitrogen, phosphorus and potassium and the fertilizer one-time application at 15 cm depth was more consistent with the nutrient needs of sugarcane compared to the conventional application. The soil integrated fertility increased by optimizing the application of fertilizer and fertilizer depth compared to conventional fertilization, could reduce the input of fertilizer.
