“…A 25 g soybean seed sub-sample was ground using the laboratory Mill 3600 (Perten, Springfield, IL, USA) and the protein, oil, fatty acids, sugars, acid detergent fiber (ADF) and neutral detergent fiber (NDF) were determined by near-infrared reflectance using the AD 7200 array feed analyzer (Perten, Springfield, IL, USA) [31,32]. Perten's Thermo Galactic PLS IQ software was used by the University of Minnesota for developing calibrations and a calibration curve was updated regularly according to Association of Official Analytical Chemists (AOAC) methods [30].…”

Soybean (Glycine max L.) seed is a major source of protein, oil, carbohydrates and other nutrients that are important for human and animal nutrition. Producers have considered applying nitrogen (N) fertilizer to soybean crop to maximize seed yield; however, its effect on seed composition is not well understood. The objective of this two-year (2015 and 2016) study was to evaluate the effects of N fertilizer sources and application rates (45, 90, 135 and 179 kg N ha −1 ) on soybean seed composition on two soil textures (clay and silt-loam) in Mississippi. The three fertilizer sources included in this study were urea with N-(n butyl) thiophosphoric triamide (Urea+NBPT), polymer-coated urea (PCU), and ammonium sulfate (AMS). Nitrogen application at 179 kg ha −1 on clay soil reduced seed protein by 1.05% compared to unfertilized soybeans in 2016. However, N application at 179 kg ha −1 increased oil content by 0.7% on clay soil compared to the unfertilized soybeans only in 2016. Nitrogen applications reduced stachyose content on both soil textures in 2015. The fatty acids showed variable response to N applications. Since, seed quality is not a trait from which growers receive an economic incentive, they are unlikely to adopt this practice for standard soybean production.

“…When soybeans reached the flowering stage, they were waterlogged for 21 days. According to Bellaloui et al (2014), soybean plants require the most N during the flowering phase to form vegetative and generative organs, resulting in a significant decrease in NRA in soybean plants after a 21-day inundation period.…”

“…There was an increase in BNF and N uptake as a result of the growth of nodules in number and mass with boron foliar application, and these results were attributed to the role of boron in the induction of nitrate assimilation by increasing protein synthesis by plant [58].…”

“…Nitrogen fixation by bacteria already is well described [56]; however, currently studies are focused in nutrients involved in this metabolism, especially micronutrients [57,58]. Among the micronutrients able to influence the BNF are boron, copper, zinc, cobalt, iron, nickel, manganese, and molybdenum, essential as structural components and enzyme activators in plants [56][57][58][59].…”

The nitrogen (N) fertilization synthetic or biological is primordial for food production worldwide. The consumption of N fertilizers in agricultural systems increased in exponential scale, mainly in developing countries. However, some negative points are associated to industrial N consumption; consequently the industry promoted ways to minimize N losses in production systems of tropical agriculture. Biological nitrogen fixation is a very important natural and sustainable process for the growth of leguminous plants, in which many micronutrients are involved, mainly as enzyme activators or prosthetic group. However, other mechanisms in the rhizosphere and molecular region still need to be clarified. Therefore, the aim of this chapter is to compile information about the historical and current affairs about the advances in N fertilization in tropical environments through a history from N fertilization worldwide, N balance in the main agricultural systems, introduction of alternative ways to avoid N losses, advances between BNF and micronutrients, as well as the effects of N absence in plant metabolisms. Biological nitrogen fixation is a very important natural process for the growth of leguminous plants, in addition many metallic nutrients, micronutrients, are involved in BNF metabolism, mainly as enzyme activators or prosthetic group. But other mechanisms in the rhizosphere and molecular region still need to be clarified.
