For modern agriculture the use of advanced nutrient management technologies, as well as the use of appropriate inputs at various productive environments are essentials to maintain yield and sustainability in agricultural systems once it aims to produce food, fiber and energy for a growing world population of around seven billion people. The researches proposed in this project are insert...
Quantifying soil N mineralization is essential since soil organic matter is the main source of N to plants. Identifying highly responsible, moderately responsible and non-responsible sites to N fertilization, by means of soil N tests, allows develop a site-specifically N recommendation system in sugarcane, increasing the agroecosystems sustainability. This study aims to develop indexes ...
Considering that the current knowledge on the response of the sugar cane yield to the N and S fertilization was obtained with experiments in only one cycle: plant cane or ratoon crop; that the sugar cane is a semi-perennial grass and as such it is dependent of the energy and nutrient reserves of the root system (roots and rhizomes) in order to sustain the vigor of ratoon plants; consid...
The efficiency of use of fertilizer nitrogen (EUN) applied to the leaves of sugar caneis high, reaching 85% when compared to the EUN applied to the soil, an average of 25%.Currently, of the total nitrogen applied to the crop's stalk, about 32% is immobilized byorganic matter and only 25-26% is absorbed by the plant, which demonstrates the lowefficiency of the use of N by sugarcane (Otto...
The species of green manure belonging to the Fabaceae family are preferred among the cover crops due to Biological Nitrogen Fixation (BNF). The N fixed by the legumes can be transferred to the main (non-legume) crop used in crop rotation or intercropping systems in order to increase the N-use efficiency of the green manure. Thus, the overall objective of the work is to evaluate the nitr...
Nitrogen (N) is the most required nutrient by maize and common bean, being necessary in low quantities at the beggining and in adequated quantities during the development of both crops. Urea is the main N source but it has a low N Use Efficiency (NUE) that is associated with N losses when this source is applied on the soil surface. A manner to increase NUE would be to use mixtures of po...

Mechanized harvesting of sugarcane (Saccharum spp.) without previous burning of straw ("green cane") is a reality in the sugarcane sector. The main concerns with this harvesting system is related to the use of nitrogen fertilizers, especially urea, which is the most common source of nitrogen (N) in Brazil and can suffer high N losses by volatilization when applied over the straw. In or...
Proper nitrogen fertilization is one of the most important requirements for high maize (Zea mays L.) yields. The nitrogen use efficiency (NUE) in Brasil is, however, very poor because nitrogen is prone to several transformations in soil like denitrification, volatilization of NH3, and in a lesser extend leaching, which may result in low utilization by the culture and increase the risk o...
In order to decrease the dependence of fossil fuels worldwide, sugarcane is a promising crop for biofuels production. However, social, environmental and economical issues should be considered for sustainable production of renewable fuels. Nitrogen fertilizers play a key role in sugarcane growth, increasing the yield of stalks, sugar and ethanol. However the use of N fertilizer improperl...

Rhizodeposition of nitrogen and carbon can increase the proportion of N and C in the soil and influence enzymatic activity, organic matter decomposition and, consequently, the availability of nutrients. The objective of this work will be evaluated (1) rhizodeposition of C and N of the cherry tomato and jack bean in monoculture and intercropping using the13C -15N double labelling method;...
The input of sugarcane straw on the soil surface can increase the N immobilization due to the high C/N ratio of this residue. However, the application of N fertilizer on sugarcane ratoons can stimulate the soil microbial population, promoting the net N mineralization. Besides mineral N from the mineralization process, plants can uptake organic compounds with low molecular weight, such a...
The estimation of mineralization may be used to adjust the recommendations of nitrogen fertilization, once that nitrogen of labile fractions is released in the initial periods of mineralization process. For better utilization of fertilization with nitrogen by crops is necessary wide understanding of nutrient dynamics in the soil. So, are objectives of the research project: to evaluate r...
