“…Further research is required to assess the feasibility of introducing P-efficiency genes into high-yielding cultivars of sugarcane to lower their P fertilizer requirements. Similarly, P-solubilizing bacteria (e.g., Agrobacterium radiobacter, Bacillus megaterium; Shankaraiah, Hunsigi, & Nagaraju, 2000), Acidithiobacillus oxidizing bacteria (Stamford, Lima, Lira, & Santos, 2008), and phosphobacteria (Ramesh, Chinnusamy, & Jayanthi, 2002), and mycorrhizal associations (e.g., Aspergillus awamori; Shankaraiah et al, 2000) have been shown to enhance P availability to sugarcane in P-deficient soils, but their ability to offset crop P fertilizer inputs still needs to be proven (Gopalasundaram, Bhaskaran, & Rakkiyappan, 2012). For example, Schütz et al (2018) showed that microbial P solubilizers and arbuscular mycorrhizal fungi can enhance yield by 15% in tropical soils with low levels of plant available P. Research is needed to identify microbial strains that can tolerate P fertilizer inputs while facilitating soil P mobilization and plant uptake, and to develop more integrated practices that combine crop and microbial engineering with lower and more targeted P fertilizer inputs (Rowe et al, 2016;Withers et al, 2018).…”

Phosphorus (P) use in global food and bioenergy production needs to become more efficient and sustainable to reduce environmental impacts and conserve a finite and critical resource (Carpenter & Bennett, Environmental Research Letters, 2011, 6, 014009; Springmann et al., Nature, 2018, 562, 519). Sugarcane is one crop with a large P footprint because production is centered on P‐fixing soils with low P availability (Roy et al., Nature Plants, 2016, 2, 16043; Withers et al., Scientific Reports, 2018, 8, 2537). As global demand for processed sugar and bioethanol continues to increase, we advocate that improving P efficiency could become a key sustainability goal for the sugarcane industry. Here, we applied the 5R global P stewardship framework (Withers et al., Ambio, 2015, 44, 193) to identify more sustainable options to manage P in Brazilian sugarcane production. We show that current inputs of P fertilizer to the current crop area could be reduced by over 305 Gg, or 63%, over the next three decades by reducing unnecessary P fertilizer use, better utilization of recyclable bioresources and redesigning recommendation systems. Adoption of these 5R options would save the sugarcane industry in Brazil 528 US$ million and help safeguard global food and energy security.

“…There was also a proportional relationship between soil quality and sugarcane yield (Diaz et al, 2010;Kumar and Chand 2013;Jeevika et al, 2015). A balanced use of organic, inorganic and biofertilizers is essential to maintain a good soil physical and chemical environment and also serves as an energy source for the soil microbial biomass (Rajesh et al, 2003;Gopalasundaram et al, 2012).…”

Maintaining or improving the soil quality is crucial for agricultural productivity. This study was undertaken to evaluate the effect of zeolite and its combination with chemical fertilizer and organic fertilizers on soil quality and sugarcane yield in the north coast of Cuba, Villa Clara province. The organic fertilizer (sugarcane filter cake-SFC), and natural mineral (zeolite-Z) and chemical fertilization (nitrogen-phosphorus-potassium-NPK) were applied as treatments. The experiment was laid out in a randomised complete block design with nine treatments and four replicates. The soil samples were taken at a depth of 0-20 cm to determine soil properties such as degree of soil aggregation, water-stable aggregates, permeability, lower plastic limit, pH in water, pH in KCl, organic matter, assimilable P 2 O 5 and K 2 O. The sugarcane yield components such as cane yield (t ha -1 ) and sucrose yield (t ha -1 ) were evaluated. Principal components analysis (PCA) and simple regression analysis were also performed. The best results on cane yield were obtained with the treatment Z 7.5 t ha -1 + SFC 22.5 t ha -1 , which represent a relative increase of 200% vs control (without fertilization). Relations between soil properties and principal component analysis confirmed the good response of zeolite application on soil quality and sugarcane yield.

“…There could be considerable benefit if the use of inorganic fertilizers could be reduced without affecting the harvest rate per hectare of sugar cane crop. One way this has been done is through the use of filter cake as a fertilizer (Gopalasundaram et al, 2012). Filter cake, or press mud is a bi-product of sugar milling.…”
