“…Forage grasses due to accelerated leaf growth rates require a large nutrient amount (Barbero et al, 2013;Costa et al, 2016). Thus, the use of wastewater in meeting the demand of these plants is a viable alternative (Silva et al, 2016(Silva et al, , 2017.…”

The wastewater has been an environmental problem, but your used as fertilizers could reduce or eliminate the application of commercial fertilizers in soil. Arbuscular mycorrhizal fungi (AMF) and nitrogen fixing bacteria (NFB) are a good parameter to analyze the impacts of this fertigationon soil. We aimed to evaluate the distribution and diversity of AMF and NFB before and after applications of wastewater or manure from green line of a cattle slaughterhouse in the irrigation of B. brizantha cv Marandu in Cerrado soil and leaf biomass productivity. The experimental design was performed in completely randomized blocks with ten biofertigation managements. The seeds of the forage were distributed in grooves with spacing of 5 cm. This seeds were covered with a soil layer. NFB and AMF diversity was performed by denaturing gradient gel electrophoresis (DGGE). The leaf biomass productivity in the biofertigation managements was higher than in the managements without the use wastewater/manure. After biofertigation managements, changes in the DGGE profile of the NFB and AMF communities were observed. These changes may be due to the difference in the sample collection period and in the soil humidification. Thus, these DGGE profiles was a good parameter to diagnose the efficacy of wastewater/manure as an alternative biotechnological irrigation.

“…Of the fodder used for this purpose, those of the genus Brachiaria correspond to 70 -80% of the area planted in Brazil. The Brachiaria ruziziensis is one of the most planted because of its high palatability, grazing support, and high dry matter production (6 to 15 t ha -1 ) [3].…”

Aims: The objective of this work was to evaluate the agronomic efficiency of the bone meal under acidification in the production of dry matter of Brachiaria ruziziensis in relation to a soluble source. Study Design: The experiment was conducted in a completely randomized design with seven treatments and three replications. Treatments included a control, single superphosphate (SS), bone meal (BM), BM treated with 10% oxalic acid, BM treated with 10% acetic acid, and BM treated with 1% to 0.5% hydrochloric acid. Place and Duration of Study: The experiment was carried out from October 2014 to February 2015, at the Experimental Farm of the Federal University of Rondônia (UNIR), located 15 km from the city of Rolim de Moura, Rondônia, Brazil. Methodology: The bone meal used in the experiment was produced manually, where bovine bones were collected and burned for carbon removal and particle reduction. The oxalic acid, acetic acid and hydrochloric acid were used to increase the solubility of the bone meal for application to the soil for growth of B. ruziziensis. Parameters evaluated were the agronomic efficiency index (AEI), phosphorus conversion efficiency (PCE), shoot dry matter (SDM), and root dry matter (RDM). Results: AEI obtained for acid treatments was above 60% and PCE satisfactory when compared to the soluble source, except for 0.5% hydrochloric acid and significantly above the BM without acid treatments. There was higher production of SDM and RDM with the soluble source (SS), however the acid treatments promoted dry matter production above the BM without acid treatments. Conclusions: The application of acids in bone meal promoted satisfactory agronomic efficiency gains for Brachiaria ruziziensis.

Cattle slaughterhouses are potential causes the environmental impacts, as it require a large volume of water in meat processing, generate large effluents amount, and promote the Cerrado deforestation for animal husbandry. Therefore, we aim was carried out to assess the effects of the soil application of a green line wastewater from a cattle slaughterhouse in the Brachiaria brizantha growth. The M1 and M2 managements did not contain wastewater of slaughterhouse. The wastewater from the 3 rd stabilization pond (M3 to M5), from reception box (M6 to M8), and manure (M9 and M10) were used in the biofertigation managements. The physical-chemical indicators levels did not show significant differences (p < 0.05) before soil preparation and after managements. However, biofertigation in the Cerrado soil can provide a mitigation of the leaching of fine soil particles and cations. In addition, maximum nitrogen dose of wastewater provided a higher leaf biomass productivity than commercial nitrogen. Thus, the fertigation with wastewater can reduce the use of water bodies to crops irrigation and the incorporation of new areas with native vegetation to the agricultural production systems.
