Boron application increases growth of Brazilian Cerrado grasses

Abstract: Nutrients are known to limit productivity of plant communities around the world. In the Brazilian Cerrado, indirect evidences point to phosphorus as the main limiting nutrient, but some fertilization experiments suggest that one or more micronutrients might play this role. Boron is one of the essential micronutrients for plants. Agronomically, it received some attention, but it has mostly been neglected in ecological studies assessing the effects of nutrients on plant growth. Through field fertilization and me… Show more

“…The potentially important contributing role of micronutrients for grassland productivity has been highlighted in fertilisation experiments (Fay et al, 2015; Lannes et al, 2016), but few studies in non‐agricultural grasslands focused on micronutrients additions specifically (however, see Lannes et al (2020) for the role of B as limiting factor in Cerrado grasslands). Therefore, the role of micronutrient deficiency in the productivity of non‐agricultural grasslands globally has not been explicitly considered.…”

“…Climate, atmospheric N deposition and soil physicochemical properties determining soil fertility (SOM, CEC, pH) were expected to be the main overarching drivers of global grassland biomass production (Bünemann et al, 2018; Huxman et al, 2004; Sala et al, 1988; Stevens et al, 2015) and their influence was therefore tested first (Figure 2c). In addition, we hypothesised that the availability of the most limiting macronutrients (NP) and/or other nutrients explain additional variation due to their important role in (co)‐limiting grassland productivity (Elser et al, 2007; Fay et al, 2015; Harpole et al, 2011; Lannes et al, 2020; Olde Venterink et al, 2001). Besides direct effects, we tested all possible indirect effects of climate on aboveground biomass through soil physicochemical properties (Zhao et al, 2019) and soil nutrients (Bünemann et al, 2018; Havlin, 2004) (Figure 2b).…”

“…For example, elements in plants such as K, Mg, sulfur (S), iron (Fe), calcium (Ca) and zinc (Zn) are involved in photosynthesis, transport of metabolites, enzyme control (co-enzymes), respiration, water flow, internal cell homeostasis and reproduction (Tripler et al, 2006;Naples and Fisk, 2010;Baribault et al, 2012;Rivas-Ubach et al, 2012;Peñuelas et al, 2013cPeñuelas et al, ,2019aKaspari and Powers, 2016;Jeyasingh et al, 2014Jeyasingh et al, , 2017Minden et al, 2020). Similarly, elements other than N, P and K may be limiting in some terrestrial ecosystems and may elicit community-level effects (Naples and Fisk, 2010;Baribault et al, 2012;Lapenis et al, 2013;Lannes et al, 2020b). For example, herbivore fitness may be compromised by the limitation of elements other than N, P and K in food (Filipiak, 2016;Filipiak and Weiner, 2017a,b).…”

“…In contrast to experiments that show that diverse ecosystems tend to be more productive and stable (Spehn et al 2005; Tilman et al, 2001), there is often a decline in diversity when productivity is manipulated by adding resources (Bobbink et al, 2010; DiTommaso & Aarssen, 1989). In savannas of central Brazil, under nitrogen and phosphorus addition, density, richness and diversity of the shrub‐tree layer and biomass of native C 3 grasses were reduced (Bustamante et al, 2012; Jacobson, Bustamante & Kozovits, 2011), while nitrogen and phosphorus, combined with other nutrients, increased the biomass of alien and growth of native C 4 grasses (Lannes et al, 2016) and boron addition increased biomass production of savanna herbaceous vegetation (Lannes et al, 2020).…”
