“…Sandy soils, with little or no nutrient or water holding capacity could benefit from the uses of red mud as soil ameliorant (McPharlin et al, 1994, Barrow, 1982, Ujaczki et al, 2015, Ujaczki et al, 2016 due to the presence of sodalite in red mud, with an estimated cation exchange capacity (CEC) that exceeds the CEC of most natural clays. In addition, the alkaline nature of red mud can be used to raise the pH of organic or acidic soils (Summers et al, 1996, Snars et al, 2004, which tend to suffer from Al phytotoxicity (Alva et al, 2002).…”

Red mud can be applied as soil ameliorant to acidic, sandy and micronutrient deficient soils. There are still knowledge gaps regarding the effects of red mud on the soil microbial community. The Biolog EcoPlate technique is a promising tool for community level physiological profiling. This study presents a detailed evaluation of Biolog EcoPlate data from two case studies. In experiment "A" red mud from Ajka (Hungary) was mixed into acidic sandy soil in soil microcosms at 5-50 w/w%. In experiement "B" red mud soil mixture was mixed into low quality subsoil in a field experiment at 5-50 w/w%. According to average well color development, substrate average well color development and substrate richness 5-20% red mud increased the microbial activity of the acidic sandy soil over the short term, but the effect did not last for 10 months. Shannon diversity index showed that red mud at up to 20% did not change microbial diversity over the short term, but the diversity decreased by the 10 th month. 30-50% red mud had deteriorating effect on the soil microflora. 5-20% red mud soil mixture in the low quality subsoil had a long lasting enhancing effect on the microbial community based on all Biolog EcoPlate parameters. However, 50% red mud soil mixture caused a decrease in diversity and substrate richness. With the Biolog EcoPlate we were able to monitor the changes of the microbial community in red mud affected soils and to assess the amount of red mud and red mud soil mixture applicable for soil treatment in these cases.

“…Todas as doses testadas aumentaram significativamente os teores no solo, comparados com os valores encontrados para a testemunha. Resultados semelhantes foram encontrados por McPHARLIN et al (1994) que, aplicando 0; 60; 120 e 240 t ha -1 de resíduo de bauxita para avaliar a lixiviação do fósforo, observaram que o fósforo retido na camada de 0-15 cm do solo aumentou em 34%.…”

RESUMO:O experimento foi realizado em ambiente protegido, com o objetivo de avaliar o efeito do resíduo da mineração de bauxita nos teores de macronutrientes, no solo e em plantas de cana-de--açúcar. Foram utilizados vasos de 10 L que receberam as seguintes doses de resíduo de bauxita: 0; 28;56; 84; 112 e 140 t ha -1 , utilizando-se do clone de cana-de-açúcar SP92 4221. A incorporação do resíduo de bauxita no solo proporcionou aumento nos teores dos macronutrientes do solo, sendo que apenas para o enxofre doses acima de 83 t ha -1 proporcionaram reduções desse nutriente. Já para os teores de macronutrientes determinados na folha, doses acima de 70,5; 125; 101 e 56 t ha -1 diminuíram os teores de nitrogênio, fósforo, potássio e enxofre, respectivamente. Entretanto, para o cálcio e o magnésio, a utilização do resíduo proporcionou a diminuição dos seus teores foliares. A dose do resíduo de bauxita que teve a maior produção de massa seca foi de 64 t ha -1 . PALAVRAS-CHAVE:Sacharum oficinarum, condicionador de solo, resíduo. NUTRIENT DIAGNOSIS OF SUGARCANE IN FUNCTION OF RESIDUE RATES OF THE BAUXITE MINING ABSTRACT:The experiment was carried out in green house with the objective of evaluating the effect of the bauxite mining residue in the rates of macronutrients in sugarcane and soil. Containers of 10 L were used. They received the following rates of bauxite residue: 0; 28; 56; 84; 112 and 140 t ha -1 . The used culture was the sugarcane (SP92 4221). The incorporation of the bauxite residue in the soil provided an increase in the levels of the soil macronutrients, and only for sulphur levels above 83 t ha -1, it was possible to provide reductions of this nutrient. For rates of determined macronutrients in the leaf, levels above 70, 5; 125; 101; 56 t ha -1 diminished the rates of nitrogen, phosphorum, potassium and sulphur, respectively. However, for calcium and magnesium the use of the residue provided the reduction of leaf rates. The level of the bauxite residue which had the largest production of dry mass was 64 t ha -1 .

“…The S\S process could be applied both in laboratory and in situ showing good results against the risk with the remarkable benefit of immobilizing heavy metal inside natural minerals, such as clays and zeolite or soil-compatible materials. Among these, fly ash and red muds are widely used (Apak et al, 1998;Castaldi et al, 2010;Ciccu et al, 2003;Coruh & Nur Ergun, 2010;Dermatas & Meng, 2003;Garau et al, 2011;Glenister & Thornber, 1985;Gray et al, 2006;Lombi et al, 2002a;McPharlin et al, 1994;Summers et al, 1996). In particular, many authors show that amendment of contaminated soil with red mud results in a durable reduction in metal mobility and also in a smaller risk of metal remobilization if soil pH were to decrease (Gray et al, 2006;Lombi et al, 2002a).…”
