“…The bacteriostatic action of the biofertilizer on the population of X. campestres pv. Vesicatoria was registered in bell pepper seedlings -Capsicum annuum (Deleito et al, 2004). The authors attributed to the reduction of the infection the complex interaction involving the antibiotic effect of the metabolites produced by the microorganisms of the biofertilizer, the microbial competition of the phylloplane, and nutritional effects to the plants.…”

Bovine manure biofertilizers can exert physical, chemical, and biological effects on the soil and the phytoprotective, physiological, and productive actions in horticultural crops. The literature review was performed to compile information on the production, uses, and effects of bovine manure biofertilizers on soil properties and plants. Biofertilizers are produced by organic components, minerals, and inoculants. Among the organic sources, the bovine manure is the most used. The fermentation of the bovine manure in water constitutes the Vairo biofertilizer, the most employed in Brazilian horticulture. With the chemical enrichment of this preparation came the Supermagro, Agrobio, and Agrobom biofertilizers. In the soil, it can act in the improvement of soil fertility, physical properties, and in the diversity and abundance of the biota. Also, it can act in control of pests and diseases, leaf composition concerning macro and micronutrients, and in the production and post-harvest quality of horticultural crops. Therefore, this review describes the preparation, chemical composition, and utilization of bovine manure biofertilizers in both soil and plants, offering perspectives of research on the formulations, application, and effects of these inputs on horticultural species.

Biofertilizers are sustainable alternatives to producers in order to reduce or replace the use of chemical fertilizers. Act directly or indirectly on all or parts of plants grown by providing nutrients and increasing its productivity. These formulations are comprised of easily accessible to the producer materials such as crop residues and use micro-organisms that act beneficially increasing the availability of nutrients to plants through biological processes. The Hortbio® is enriched aerobic bio-fertilizer developed by Embrapa Vegetables -DF. The aim of this study was to characterize the Hortbio® with regard to respect for their cultivable microbiota, indole acetic acid (IAA) concentration and biological contaminants, and to evaluate the effect of biofertilizer doses in different varieties of lettuce. Was used, for evaluation of microbiota, different biofertilizer production times, these being 0, 5, 10, 15, 20, 25 and 30 days of either preparation, they being Hortbio® 0 and 40 Hortbio® and inoculum EM (effective microorganisms). Was used culture media for the isolation of micro-organisms, these being R2A, Martin AC, and THSM MYGP for the isolation of total bacteria, total fungi, actinomycetes, Trichoderma spp. and yeast, respectively. The microorganisms were identified by DNA sequencing. For the determination of IAA concentration was used Hortbio® 0 in production times 10, 20 and 30 using the HPLC technique. For the valuation of biological contaminants, we evaluated the presence of Salmonella spp. and fecal coliforms in the product, as well as helminths and nematodes in five different biofertilizer. All those with 10 days of preparation. The effect of different doses of biofertilizer (0, 50, 100, 150, 200, 250 kg ha -1 N) of three types of lettuce (leaf, crisp head and cos lettuce) in a randomized trial conducted in pots. They evaluated different agronomic traits of lettuce, which are: the height (HP) and width of the plant (WP) of plants, fresh mass (FM), the average number of leaves (ANL) and the length (SL) and stem diameter (SD). Soil fertility was assessed by determining the Ca 2+ , Mg 2+ , K + , Na + , P, H+Al, cation exchange capacity (CEC), pH and soil organic matter (SOM). 217 microbial isolates were recovered, with 120 bacteria, 61 yeasts and 36 fungi. Among the found genera,

RESUMOObjetivou-se com este trabalho avaliar os efeitos da adubação complementar com o biofertilizante Supermagro, a urina de vaca e a manipueira na produção e nos teores de nutrientes nas folhas da mexeriqueira (Citrus deliciosa Tenore cv. Rio) em sistema de cultivo orgânico. O delineamento experimental adotado foi o de blocos casualizados, com cinco repetições. Todas as plantas foram adubadas com esterco bovino e os tratamentos aplicados foram complementares a essa adubação. Foram constituídos dez tratamentos obtidos pelos tipos de adubo e por seu modo de aplicação (via solo, via pulverizações foliares ou ambos) e uma testemunha. A produção foi avaliada nas safras de 2006 e 2007 e os teores de nutrientes nas folhas, em 2005, 2006 e 2007. A adubação complementar não influenciou a produção de frutos. As aplicações de urina de vaca via solo, com ou sem aplicação foliar, e da manipueira, independentemente do modo de aplicação, contribuíram para elevar os teores de S nas folhas. O Supermagro aplicado via solo aumentou os teores de B nas folhas e, quando aplicado via foliar, aumentou os teores de Zn. Palavras-chave:Citrus deliciosa Tenore, biofertilizante, Supermagro, urina de vaca, manipueiraComplementary fertilization to willowleaf mandarim in organic cultivation system ABSTRACT The aim of this work was to evaluate the effect of complementary fertilization with the biofertilizer Supermagro, cow urine and cassava wastewater in the production and levels of nutrients in the leaves of willowleaf mandarim 'Rio' (Citrus deliciosa Tenore) in organic cultivation system. The experimental design used was the randomized blocks, with five replications. All plants were fertilized with cow manure and the applied treatments were complementary to this fertilization. Ten treatments were constituted, by fertilizer types and by modes of application (soil, foliar spray or both) plus a control. The complementary fertilization did not affect the fruit production. However, the cow urine applied on soil, with or without foliar spray, and cassava wastewater, independently of mode of application, increased S contents of leaves. The biofertilizer Supermagro when applied in soil increased B content of leaf, and when it was applied by foliar sprays increased Zn content of leaves.
