“…Biofertilizers are biological products containing living microorganisms that, when applied to seed, plant surfaces, or soil, promote growth by several mechanisms such as increasing the supply of nutrients, increasing root biomass or root area, and increasing nutrient uptake capacity of the plant (Vessey 2003). Biofertilizers can be used as complements to mineral fertilizers (Canbolat et al 2006). Microbial inoculants mainly include free-living bacteria, fungi, and arbuscular mycorrhizal fungi (AMF) (Berg 2009;Dodd and Ruiz-Lozano 2012;Vessey 2003) that were isolated from a variety of environments including soil, plants, plant residues, water, and composted manures.…”

Background Plant biostimulants are diverse substances and microorganisms used to enhance plant growth. The global market for biostimulants is projected to increase 12 % per year and reach over $2,200 million by 2018. Despite the growing use of biostimulants in agriculture, many in the scientific community consider biostimulants to be lacking peer-reviewed scientific evaluation. Scope This article describes the emerging definitions of biostimulants and reviews the literature on five categories of biostimulants: i. microbial inoculants, ii. humic acids, iii. fulvic acids, iv. protein hydrolysates and amino acids, and v. seaweed extracts.Conclusions The large number of publications cited for each category of biostimulants demonstrates that there is growing scientific evidence supporting the use of biostimulants as agricultural inputs on diverse plant species. The cited literature also reveals some commonalities in plant responses to different biostimulants, such as increased root growth, enhanced nutrient uptake, and stress tolerance.

“…In tropical soils, this P is rapidly fixed. Hence, one way of minimizing these losses is the application of inoculants containing bacteria that can solubilize this P and transform it into forms assimilable by plants, resulting in better use and crop yield (Wakelin et al, 2004;Canbolat et al, 2006;Dias et al, 2009), and contributing to sustainability.…”

Sugarcane has a high demand in nitrogen, increasing costs and causing damages to the environment. It is necessary to find alternatives to reduce nitrogen fertilizers use. Diazotrophic bacteria have capacity to promote growth in grass with potential to fix N 2 and solubilize inorganic phosphate. This study aimed to evaluate bacterial community associated with different sugarcane varieties in Northeastern Brazil, select bacteria with plant growth-promoting characteristics, and identify endophytic and epiphytic bacterial lineages in sugarcane. Endophytic bacteria of leaves and roots and epiphytic bacteria of rhizoplane were isolated from three sugarcane commercial varieties and selected for their capacity to fix N 2 and solubilize inorganic phosphate. Bacterial strains from different morphological groups were isolated and a sample of 27 strains with potential for the simultaneous development of these characteristics were selected and identified. The bacterial community that interacted with sugarcane was more associated with rhizoplane and roots regions than with leaves, and had a high potential to fix N 2 and solubilize inorganic phosphate. Bacterial lineages were mainly from genera Pantoea sp. and Burkholderia sp., but there were also genera Enterobacter sp., Klebsiella sp. and Pseudomonas sp. and two lineages at the species level: Pantoea stewartii and Burkholderia cenocepacia.

“…O relato de solubilização de fósforo no solo por rizobactérias e aumento do fósforo disponível no solo pode ser encontrado na literatura por diversos autores (Richardson, 2000;Canbolat et al, 2006). Esse efeito fica mais evidente quando se compara o tratamento T4M (I-1, NPK100) com o T1M (SI, NPK100) que receberam adubação NPK adequada ao desenvolvimento da cultura, sendo que o T4M apresentou concentração foliar de fósforo 22 vezes maior que o tratamento sem inóculo.…”

Eutroférrico. The NPK fertilization was carried out on the ground where the base saturation was previously corrected by the addition of calcium carbonate. Maize cultivation inoculation was made in the seeds and the experimental design was completely randomized type (3×3) by varying the type of inoculum, and amount of nitrogen-phosphorus-potassium nutrients. The experiment with soybeans followed the design (3×3×2) by varying the type of inoculum, amount of NPK and type of inoculation (seed or soil). The experiments were performed in triplicate. Ten seeds were planted and were determined after 15 days the germination percentage and thinning carried out, leaving three plants per pot, which were cultured for 71 days, keeping the amount of water in 60 % of the soil retention capacity. The results showed that the maize plants had higher dry matter root when he received the inoculum 1 and NPK fertilization in ideal concentration for culture and had a higher content of phosphorus and potassium in the shoots than the other treatments. In soybean cultivation, the inoculum 2 was more favorable to the dry matter yield of shoot, number of pods and seeds, regardless of NPK fertilization level received when the bacteria were inoculated in the soil. The results indicated that the formulations used have biotechnological potential to increase the development and plant nutrition corn and soybeans.

IntroduçãoA demanda crescente pela produção de alimentos, como consequência do crescimento populacional, exige o desenvolvimento de novas tecnologias aplicadas à agricultura para tornar esta atividade cada vez mais produtiva. O modelo de produção agrícola atual privilegia o uso intensivo de insumos, como fertilizantes e agrotóxicos. O uso indiscriminado desses insumos pode causar danos à saúde e ao meio ambiente, aumentando a importância de se adotar técnicas e/ou práticas mais sustentáveis e que minimizem os impactos desta atividade (Mao et al., 2012;Canellas et al., 2015).O uso de rizobactérias promotoras de crescimento de plantas (RPCPs) pode constituir uma alternativa biológica promissora para aumentar a produtividade das culturas (Coelho et al., 2007; Marques et al., 2010) (Gomes et al., 2003;Chamangasht et al., 2012). Nos casos citados, a promoção do crescimento está ligada a fatores como a maior produção de grãos, maior germinação em casa de cultivo e no campo, melhor absorção dos nutrientes, aumento tanto no peso seco quanto na altura dos cultivares dentre outros.As RPCPs quando aplicadas ao solo, em formulações simples ou misturas de inoculantes, podem causar diferentes efeitos no desenvolvimento das plantas, tais como, aumentar a germinação das sementes, a emergência das plântulas e beneficiarem o crescimento das mesmas (Lazzaretti e Bettiol, 1997). O crescimento vegetal pode ser promovido através de várias formas, dentre elas, fixação biológica de nitrogênio, síntese de hormônios e outras moléculas, controle biológ...
