“…A work conducted by Boschiero (2017), at the São José da Estiva Power Plant, in the municipality of Novo Horizonte-SP, between 2010 and 2015 and in two places, made room for some considerations. A Place 1, using ammonium nitrate (AN) and urea (U) at the dose of 100 kg N ha -1 , the productivity did not respond to the N fertilizer application since N did not promote productivity increase in all 5 ratoons.…”

“…The rainfall during the period in which the work was conducted may have interfered with the results, as stressed by Trivelin (2000), in 17 years of works presented as theses for the licensure title, and by Boschiero (2017), at the São José da Estiva Power Plant between 2010 and 2015. It happened due to the great amount of rain right after the soil fertilization, in October and November 2018, which may have caused N leaching, and due to a period of drought in the following months-December 2018 and January 2019-which delayed the foliar N application.…”

In Brazil, sugarcane (Saccharum spp.) is considered one of the most economically important crops. Nitrogen (N) is one of the most required elements in sugarcane cultivation. Nevertheless, the information about the soil and foliar applications of this nutrient in crops are discrepant. Therefore, the importance of this study is evident. Given the above, this study aimed to evaluate the soil-applied and foliar N fertilization of sugarcane. The experiment was conducted at the Araporã Bioenergia S.A. power plant, located at Fazenda Santa Rita, in the municipality of Itumbiara-GO. The 5 × 5 factorial design was adopted, with four repetitions, including five doses of soil-applied ammonium nitrate and five doses of foliar Amidic N polymer. The nutrient extraction, the experiment’s initial and final total chlorophyll content, the biometric indexes and the industrial quality indexes were analyzed for sugarcane. The ammonium nitrate doses caused differences in fiber, sacarose content, total recoverable sugar, sugar cane Brix, magnesium, and zinc, which was statistically different for the foliar polymer doses. There was no increment of the production variables with the increase of the nitrogen supply in the soil. On the other hand, the levels of zinc and magnesium in the leaves increased 12% and 27%, respectively, reflecting the importance of this fertilization in sugarcane cultivation.

“…The most common nitrogen fertilizers used in Brazilian sugarcane fields are ammonium nitrate (33% N), urea (45% N), and ammonium sulfate (21% N). It is interesting to note that each option has positive and negative aspects, such as (i) ammonium nitrate has N in two forms: nitrate (NO 3 − ) and ammonium (NH 4 + ), in which ammonium has been reported to be a mineral preferential form uptake by sugarcane [10]. In addition, there is not losses due the volatilization of ammonia by this N source (ammonium nitrate) in tropical soils.…”

Currently sugarcane is cultivated in Brazil in intensive mechanization during all cultural practices, since planting, harvesting until fertilizer applications. In this sense, to increase the sugarcane yield which it was stagnant along the last 5 years, it is necessary looking for alternatives to management the crop and maximize the yield gain. One alternative is trough the adjustment the N-fertilization in green cane crop according to the IPNI guidelines-"4R Nutrient Stewardship System" (International Plant Nutrition Institute-IPNI) program which seeks to apply fertilizer in the right location, at the right time, in the right amount and the right source. Therefore, the main goal of this chapter is shows these alternatives and the yield gains that it was obtained in researches during 2013-2017.
