“…Similar to total aboveground corn N uptake, grain N uptake increased linearly as fertilizer N increased (Table 2, Fig. 1), agreeing with the results of Halvorson et al (2006), Barbieri et al (2008), and Holou et al (2011). With each kg N ha −1 increase in fertilizer N applied, grain N uptake increased by 0.38 kg N ha −1 .…”

Improving nitrogen use e ciency (NUE) in corn (Zea mays L.) is critical for optimizing yield and reducing environmental impact. Stover removal in continuous corn (CC) for biofuel production, coupled with reduced-tillage systems, could alter NUE and residual soil nitrate-N. Experiments were conducted in Minnesota over 3 yr to determine how N uptake, NUE, and residual soil nitrate-N are a ected by stover (remove and retain), tillage (chisel-[CT], strip- [ST], and no-till [NT]), and fertilizer N (0, 45, 89, 134, 179, and 224 kg N ha -1 ) management. ere was a linear response of grain and total aboveground N uptake to fertilizer N across stover management and tillage treatments. Stover removal increased recovery e ciency for ST and NT at fertilizer N rates ≤134 kg N ha -1 , but did not enhance N recovery in plots fertilized at rates >134 kg N ha -1 . Internal e ciency was 5% greater with stover removal with no fertilizer N, but did not change with fertilizer N application. Stover removal did not a ect agronomic e ciency in CT but did enhance it in ST and NT at fertilizer N rates ≤134 kg N ha -1 . Residual soil nitrate-N to a depth of 1.2 m was 10 to 16 kg NO 3 -N ha -1 greater with stover removal at fertilizer N rates of 134 to 224 kg N ha -1 . Greater residual soil nitrate-N with stover removal indicates a need for judicious management of N when stover is removed in intensively-managed Upper Midwestern CC systems.

“…Plant uptake of Cu increased as N rate increased in both Harare and Kiboko. This N rate effect on Cu uptake was also found by Holou et al ( 2011 ) in Benin. There may have been a link between the increase in S and Cu uptake as soil inorganic S has also been found to complex with Cu (Marschner 2011 ; Bindraban et al 2015 ).…”

“…The application of N increased P uptake, with the exception of a few hybrids in Embu. Feil et al ( 1992 ) and Holou et al ( 2011 ) also found that N fertilizer applications increased P uptake consistently in continuous maize cropping systems. The application of N fertilizer has been found to increase root branching, particularly closer to the surface where P levels are highest (Postma et al 2014 ).…”

“…Therefore, it is important to look at the status of multiple nutrients at once. Globally, studies have looked at the impact of N fertilizer on the uptake of non-N nutrients such as phosphorus (P), potassium (K), and sulfur (S) (Feil et al 1992 ; Holou et al 2011 ; Ciampitti et al 2013 ) and micronutrients (Ciampitti and Vyn 2013 ), but no such studies exist in SSA. These global studies have primarily focused on higher N fertilizer rates than what is typically applied in SSA, limiting the direct applicability of their findings to smallholder farmers in SSA.…”

Low fertilizer application rates for several decades have depleted soil nutrients in Sub-Saharan Africa (SSA) and contributed to relatively stagnant maize (Zea mays L.) yields. As maize is a staple crop, nutrient depletion has resulted in major food insecurity. While one potential solution is to apply more nitrogen (N) fertilizer, previous studies in SSA have found maize yield responses to be variable, likely because N is often not the only limiting nutrient. This study aimed to determine the impact of consecutive N fertilizer applications on plant uptake and available soil reserves of non-N nutrients. Maize was grown continuously in 3 sites that were representative of the ecosystem variability found in East/Southern Africa (Embu, Kenya; Kiboko, Kenya; Harare, Zimbabwe) at 4 different N fertilizer rates (0-160 kg N ha -1 ) from 2010 to 2015. Following the final season, grain, stover, and soil (sampled at different depths to 0.9 m) samples were analyzed for essential plant nutrients. Nitrogen fertilizer increased plant uptake of P, S, Cu, and Zn by up to 280%, 320%, 420%, and 210%, respectively, showing potential for mitigating non-N nutrient deficiencies in 2 of the 3 sites. Cumulatively, however, there was a net negative effect of higher N rates on the P, K, and S soil-plant balances in all sites and on the Mn and Cu soil-plant balance in Kiboko, indicating that applying N fertilizer depletes non-N soil nutrients. While N fertilizer enhances the uptake of non-N nutrients, a balanced application of multiple essential nutrients is needed to sustainably increase yields in SSA.

“…Further, Malik et al (2012) elucidated that approximately 80-90% of applied mineral P becomes plant unavailable due to opposing soil conditions. Feil et al (1992) and Holou et al (2011) expounded that additional N application could consistently increase P uptake under a continuous corn cultivation system. The applied N fertilizer could proliferate root branching in surface portion where closer to higher P concentration (Postma et al 2014).…”

Background Hardsetting soils are considered problem soils due to its behavior of becoming hard and unbearable to cultivate not until rewetted. Few investigations were conducted in this kind of problem soil; hence, information about biomass yield and nutrient uptake is still elusive. This study investigated the impact of potentially hardsetting soil on the biomass yield and nutrient uptake of sweet corn under no-tillage cultivation system with varying fertilization treatments. Results The application of full NPK + 1 Mg ha−1 VC increased stover and grain yield by 26–106% and 11–135%, respectively. Approximately 64% and 112% of sweet corn stover and grain yield increased when treated with full NPK. Highly significant quadratic relationship (P < 0.001) was revealed between total biomass yield and nutrient uptake of sweet corn, implying that 98–99% of the variation in total biomass could be elucidated by its nutrient uptake. Further, this indicated the suitability of nutrient uptake function that could be used as an estimate in the progression of total biomass accumulation. The application of full NPK showed statistically significant (P < 0.001) nitrogen and phosphorus use efficiency across treatments. The soil in the experimental area was a potentially hardsetting soil due to its rapid soil strength development at least 4 days from wetting. This implies that with continued use, proper soil management must be implemented like reduced tillage and organic matter application to facilitate structure formation and binding of soil particles by labile fraction in organic matter. Conclusion Application of organic amendment in combination with inorganic fertilizer could be a sustainable production strategy on sweet corn production system in potentially hardsetting soil under no tillage through enhanced nutrient uptake and biomass accumulation.
