“…In their work, plants presented reduced growth and large amounts of accumulated urea due to the reduction of urease activity. Similar results were obtained previously by Walker et al (1985), Krogmeier et al (1991) and more recently by Moraes et al (2009), Barcelos et al (2018), and Freitas et al (2018). Therefore, the addition of Ni in solutions of urea for spraying or fertigation could also increase the N fertilizer use efficiency and maximize the profits of farmers.…”

Nickel is an essential element in plants, mainly acting as a component of the urease enzyme. Therefore, its use in foliar solutions could increase nitrogen use efficiency. This work aimed to evaluate leaf nitrogen absorption in coffee seedlings (1-year-old), using two nitrogen application rates with nickel presence or absence, during 24 hours. The results showed, however, that nickel addition to the leaf solution impairs the absorption of nitrogen, at least on the first day after application.

“…Therefore, Ni application might not have been a major factor that could have significantly affected P n. However, other studies, in different species, demonstrated a positive effect on P n levels, chlorophyll content, and yield when Ni was applied. Moraes et al (2009) stated that the growth of rice plants depended on the N source provided, and they found that P n levels decrease when Ni or molybdenum (Mo) was absent. Gheibi et al (2009) found that wheat showed higher chlorophyll content when Ni was applied.…”

“…Research on rice (Oryza sativa L.) demonstrated an increase in dry weight and amino acids on plants grown with urea-N, plus a supply of Ni, at a rate of 0.5 mmol • m -3 (Gerend as et al, 1998). Therefore, an indirect relationship could exist between Ni supply to plants and P n levels (Moraes et al, 2009).…”

In recent years, nickel (Ni) deficiency symptoms has been observed in commercial pecan [Carya illinoinensis (Wangenh.) K. Koch.] orchards in New Mexico. Nickel deficiency can cause a reduction in lignin formation, which could affect the risk for breakage on pecan tree shoots. Ni deficiency might furthermore disrupt ureide catabolism in pecan and, therefore, could negatively affect nitrogen (N) nutrition in the plant. The objective of this study was to identify the effects of Ni and N fertilizer applications, at two rates, on net photosynthesis (Pn), leaf greenness (SPAD), and branch lignin concentration in New Mexico’s nonbearing pecan trees. Sixty trees for year 2012 (Pawnee and Western cultivars) and 40 trees for year 2013 (Pawnee cultivar) were used at two New Mexico locations (Artesia and Las Cruces) to evaluate the effects of Ni and N on tree measures. Treatments were as follows: (1) High N plus Ni (+Ni); (2) Low N no Ni (−Ni); (3) High N −Ni; and (4) Low N +Ni. In 2012 and 2013, there was an increase in leaf greenness for each location and cultivar (tree group) through time (June to September). Photosynthesis measures in 2012 differed between tree group, time in the season, and N and Ni treatments. In 2013, Pn was influenced by tree group and time (P < 0.0001), but N and Ni interaction did not present a significant effect related to Ni benefits. Photosynthesis varied over time in 2012 and 2013, with an inconsistent pattern. In this study, Ni application at the high N rate had a negative effect on ‘Pawnee’ Pn early in the season at the Artesia site, but this application had a positive effect for ‘Western’ from Artesia at the low N level, also early in the season. Lignin content varied between tree groups only. The application of N and Ni did not affect lignin in pecan shoots. The results show an inconsistent pattern regarding the benefits of Ni on nonbearing pecan orchards for leaf greenness, Pn, and lignin content during the 2-year study. Future studies on Ni should focus on pecan trees exhibiting leaf Ni deficiency symptoms or on soils with less than 0.14 mg·kg−1 of DTPA extractable Ni, as well as the long-term effect of Ni on pecan growth and development to optimize the addition of Ni into an efficient fertilization program.

“…Interestingly however, PDM and NREs achieved with the double inhibitor (nBTPT plus DCD) were not significantly better than those with urea alone. Moraes et al (2009) applied urea + Mo to glasshousegrown rice plants. Dry matter yield, chlorophyll concentration, net photosynthetic rate, and urease activity were all increased, although nitrate reductase activity was reduced.…”

A one year field experiment was conducted to assess the efficiency of urea fertilizer applied to pasture near Lincoln University, New Zealand. Urea with or without (±) molybdenum (Mo) were applied to field plot, with a urease inhibitor [N-(n-butyl) thiophosphoric triamide (nBTPT), nBTPT + elemental sulphur (S), and nitrification inhibitor dicyandiamide (DCD) + nBTPT defined as a double inhibitor (DI) in spring 2005. Mo was sprayed at the rate of 50 g Mo/ha/yr once. Urea ± various inhibitor and S treatments were broadcast at a rate of 30 kg N/ha 5 times over one year. The Mo alone treatment increased pasture dry matter (PDM) yield by 8.9%. Molybdenum, when applied together with urea+nBTPT+S, urea+nBTPT and urea alone, caused an initial depression in PDM yield by 14.2, 13 and 5.6% respectively. However, these depressions in yield disappeared from the second pasture cut. Over a one year period, Mo applied with urea+nBTPT, urea+DI and urea+nBTPT+S produced 18179, 16716 and 18253 kg DM ha -1 respectively, compared to 16171 kg ha -1 for urea+Mo. Pastures which received no Mo, but were treated with urea+nBTPT+S, or urea+nBTPT produced 18982 and 18276 kg DM ha -1 respectively, compared to 16363 kg ha -1 for urea alone, giving an increase of 16% and 12% over urea alone. Pastures receiving Mo, together with urea+nBTPT or urea+nBTPT+S, also showed improvement in N uptake and N recovery, compared to urea alone. Applying urea with nBTPT and S have the most potential to improve urea efficiency.
