“…Treatments containing green manure plus mineral N changed the soil attributes by increasing Ca and Mg contents, sum of bases, pH and base saturation and decreased potential acidity (Ambrosano et al 2005). Park et al (2010) opined that inorganic N fertilizer to the plant crop of sugarcane crop can be substantially reduced, or even eliminated by 'good' legume fallow crop that is not harvested. Potential reductions in fertilizer application rate could be up to approximately 100% in the first ratoon and 60, 25 and 10 in the subsequent ratoons.…”

Integrated nutrient management holds great promise in meeting the growing nutrient demands of intensive sugarcane agriculture and maintaining productivity at higher levels with overall improvement in the quality of resource base. It helps to improve and sustain soil fertility and provides a sound basis for crop production systems to meet the changing needs. Balanced use of organic, inorganic and biofertilizers is essential to maintain a good soil physical and chemical environment and also serve as energy source for the soil microbial biomass. Sugar productivity can be sustained by replenishing the nutrients removed by crops through proper recycling of crop residues and factory wastes along with biofertilizers. As organic manures often leave profound residual effect, recommendations need to be made on cropping system basis.

“…Nevertheless, sugarcane growers normally maintain the usual N rates that are applied on ratoon crops, neglecting possible residual effects of N fixed by legumes on subsequent ratoon. Park et al [110] simulated the residual effect of N fixed by soybean (in the absence of grain harvesting) during a sugarcane-growing season in Australia. They observed a potential for reduction of 100 % of N in the plant cane, and 60, 25, and 10 % in subsequent ratoon crops, respectively.…”

Land area devoted to sugarcane (Saccharum spp.) production in Brazil has increased from 2 million to 10 million ha over the past four decades. Studies have shown that, from an environmental perspective, the transformation of nitrogen (N) fertilizers into N 2 O gases can offset the advantages gained by replacing fossil fuels with biofuels. Our objectives here were to review recent developments in N management for sugarcane-biofuel production and assess estimates of N use efficiency (NUE) and N losses based on future scenarios, as well as for life-cycle assessments of bioenergy production. Approximately 60 % of N-based fertilizer applied to sugarcane fields in Brazil is recovered by plants and soils, whereas N losses to leaching and N 2 O emissions can average 5.6 and 1.84 % of the total applied N, respectively. Maintenance of trash, rotation with N-fixing legume species, and optimization of byproducts usage have potential for reducing the N requirements of sugarcane cultivation in Brazil. Moreover, the development of sugarcane genotypes with higher NUEs, along with management systems that consider soil capacity of mineralization, is required for improving the NUE of sugarcane. Strategies to maintain N as NH 4 + in sugarcane-cropped soils also have the potential to reduce N losses and enhance NUE. The development of secondgeneration biofuels is important for increasing biofuel production while simultaneously maintaining N rates and improving NUE, and sugarcane systems in Brazil show potential for sustainable biofuel production with low N rates and limited N 2 O losses. Reducing N rates in sugarcane fields is thus necessary for improving sugarcane-based biofuel production and reducing its environmental impacts.

“…Research regarding sugarcane production is extensive, and includes studies of sugarcane production under no-tillage management (Marasca et al, 2015), the use of organic residuals as fertilizers (Pina et al, 2015), and possible plant rotation with legume (Park et al, 2010). There are a few studies regarding the interactions between sugarcane and microbial communities, but these have primarily focused on specific microbial groups such as endophytes (Mendes et al, 2007;Magnani et al, 2010;Stuart et al, 2010), and bacterial communities in the rhizosphere (Luvizotto et al, 2010).…”

Aim Despite the important roles that microbial communities play world‐wide, relatively little attention has been given to the processes that shape their distributions. Of those studies that have addressed this question, the vast majority has focused on temperate regions and relatively undisturbed environments. In particular, tropical agricultural environments have been rarely studied, and it is commonly assumed that agriculture reduces spatial variation in microbial communities, especially in soil. Here, we evaluated the diversity and abundance of fungal communities in soils used for the cultivation of the world's largest crop, sugarcane, in the world's largest producer, Brazil. Location State of São Paulo, Brazil. Methods Our study sampled across 23,022 km2 of the State of São Paulo, Brazil, in an area that is a major producer of sugarcane. The composition of the fungal communities was estimated via terminal restriction fragment length polymorphism (T‐RFLP) analysis, and the fungal abundance was estimated by quantitative PCR (qPCR). Results We observed that the variance in community composition explained by soil characteristics was 2.88%, and that explained by climate variables was 2.93%. In contrast, geographical distance explained 50.75% of the variance. Moreover, the distribution of fungal species abundance fits a neutral model that assumes only dispersal and drift better, rather than models that assume environmental filtering. Main conclusions Our work demonstrates that fungal communities in soil can exhibit biogeographical patterns, even in agricultural soils, and that these patterns are likely to be due at least in part to dispersal limitation.
