Micronutrients in the Soil and Wheat: Impact of 84 Years of Organic or Synthetic Fertilization and Crop Residue Management

Abstract: Crop residues are an important source of plant nutrients. However, information on the various methods of residue management on micronutrients in soil and wheat (Triticum aestivum L.) over time is limited. A long-term (84-year) agroecosystem experiment was assessed to determine the impact of fertilizer type and methods of crop residue management on micronutrients over time under dryland winter wheat-fallow rotation. The treatments were: no N application with residue burning in fall (FB), spring (SB), and no res… Show more

“…Soil sampling and laboratory analysis. Soil sampling and laboratory analysis process were similar to that of previous research of similar kind conducted in CBARC [36][37][38][39][40][41] . Soil cores collected at the 0-10 cm, 10-20 cm, 20-30 cm, and 30-60 cm depths from 1995, 2005, and 2015 were used in this study.…”

“…Under different fertilizer and tillage treatments, Shiwakoti et al (2019a) found no differences in wheat grain mineral concentration except for manganese (Mn), which increased linearly with nitrogen (N) fertilizer rates. A different yet similar study demonstrated positive correlations between wheat grain Mn concentration and N fertilization, and greater N and Zn concentrations in wheat grain when fertilized with either farmyard manure or inorganic N (Shiwakoti et al, 2019b;Shiwakoti et al, 2020). Shiwakoti et al (2020) also reported an increase in N and S concentrations in wheat grain over time, speculating this could be due to greater N concentration in wheat grain occurring in cases where less rainfall occurred during the growing season.…”

“…Further, Parfenova et al (2019) found crop growing conditions would be established in some of the permafrost zones of Siberia under RCPs 2.6 and 8.5 by 2080, favorable for wheat and maize (silage) production. These crops are commonly managed via open burning practices in the U.S., eastern Europe, Russia, and Canada (Kutcher and Malhi, 2010;McCarty et al, 2017;Theesfeld and Jelinek, 2017;Shiwakoti et al, 2019;Thompson and Morrison, 2020). Thus, seasonality of burns and management of croplands, grasslands, and deciduous forests may occur at times when transport of emissions to the Arctic is likely, i.e., late winter/early spring for Russia (Hall and Loboda, 2018;Qi and Wang, 2019) and Canada and north central U.S. (Viatte et al, 2015), respectively.…”
