“…Soil under these conditions is considered to be suitable for maize production (Shamshuddin et al 1991). The result of the current study is consistent with that conducted earlier by Ismail and Shamshuddin (1993). Dolomitic limestone applied at 2 t ha (1 can reduce H ' stress and Al 3' toxicity in the long run and is less costly than biochar.…”

. 2015. Effects of biochar and/or dolomitic limestone application on the properties of Ultisol cropped to maize under glasshouse conditions. Can. J. Soil Sci. 95: 37Á47. Ultisols in the tropics are characterized by low pH and high exchangeable Al. Maize grown on them produces low yield. A study was conducted to determine changes in soil properties and their subsequent effects on maize growth, resulting from oil palm empty fruit bunch (EFB) biochar and/or dolomitic limestone application. The results show that the application of the EFB biochar improved soil fertility by increasing soil pH. The Al 3' activities in the soil solution decreased exponentially with increasing rate of the biochar application. The decrease in Al in the biochar-treated soil occurred because:(1) at the rate of 5 t ha(1 , soil solution pH increased significantly, precipitating Al as gibbsite; and (2) the biochar was able to fix some of the Al by chelation. Application of the biochar alone or in combination with lime significantly improved maize growth. The critical Al 3' activity for maize grown on Ultisol was 10 mM, while critical pH was 4.7Á4.8. Maize grown on the EFB biochar-amended soils produced greater root length compared with that of the control. The optimal rate of EFB biochar application to improve the productivity of the Ultisol for maize production under glasshouse condition was 5Á10 t ha Les auteurs ont entrepris une e´tude pour de´terminer comment l'application de biocharbon venant de la masse des fruits vides (MFV) du palmier a`huile ou de chaux dolomitique, ou des deux, modifie les proprie´te´s du sol et la croissance du maı¨s. Les re´sultats indiquent que l'application de biocharbon MFV rend le sol plus fertile en augmentant son pH. L'activite´des ions Al 3' dans la solution de sol diminue de fac¸on exponentielle avec la quantited e biocharbon applique´e. La baisse de la concentration d'ions Al dans le sol amende´avec du biocharbon est attribuable ad eux phe´nome`nes: 1) quand le taux d'application de´passe 5 t par hectare, le pH de la solution de sol augmente de manie`re significative, ce qui entraıˆne la pre´cipitation des ions Al sous forme de gibbsite; 2) le biocharbon fixe une partie de l'aluminium par che´lation. Appliquer du biocharbon seul ou avec de la chaux ame´liore significativement la croissance du maı¨s. Le seuil critique en ce qui concerne l'activite´des ions Al 3' pour la culture du maı¨s sur les ultisols est de 10 mM, le pH critique se situant, lui, a`4,7-4,8. Le maı¨s cultive´sur les sols amende´s avec du biocharbon MFV forme des racines plus longues que celui cultive´sur la parcelle te´moin. Le taux d'application optimal du biocharbon MFV pour la culture du maı¨s en serre se situe entre 5 et 10 t par hectare.

“…Due to the low pH of Ultisols, good crops of maize could only be produced after adequate application of dolomitic limestone (Shamshuddin et al 1991;Shamshuddin and Fauziah 2010). Al 3' and AlSO 4 ' are the dominant Al species in the untreated Ultisols of Malaysia (Ismail et al 1993). The former is toxic to maize, but the latter is not.…”

SUMMARYThe industrial refining of kaolin involves the removal of iron oxides and hydroxides along with other impurities that cause discoloration of the final product and depreciate its commercial value, particularly undesirable if destined to the paper industry. The chemical leaching in the industrial processing requires treatments with sodium hyposulfite, metallic zinc, or sulfuric and phosphoric acids, in order to reduce, dissolve and remove ferruginous compounds. To mitigate the environmental impact, the acidic effluent from the leaching process must be neutralized, usually with calcium oxide. The resulting solid residue contains phosphorous, zinc, and calcium, among other essential nutrients for plant growth, suggesting its use as a macro and micronutrient source. Samples of such a solid industrial residue were used here to evaluate their potential as soil fertilizer in an incubation greenhouse experiment with two soil samples (clayey and mediumtextured). The small pH shift generated by applying the residue to the soil was not a limiting factor for its use in agriculture. The evolution of the concentrations of exchangeable calcium, and phosphorous and zinc extractability by Mehlich-1 extractant during the incubation period confirms the potential use of this industrial residue as agricultural fertilizer.Index terms: industrial residue, fertilizer, kaolin refining.( O beneficiamento industrial do caulim envolve a remoção de óxidos e hidróxidos de ferro e outras impurezas, que conferem coloração indesejável ao produto final e depreciam seu valor comercial, particularmente se destinado à indústria de papel. A lixiviação química, na linha de processamento industrial, pode ser feita com tratamentos com hipossulfito de sódio, zinco metálico e ácidos sulfúrico e fosfórico, para redução, solubilização e remoção de compostos ferruginosos. A fim de minimizar o impacto ambiental, o efluente ácido, procedente da etapa de lixiviação, deve ser inicialmente neutralizado, usualmente por óxido de cálcio. O resíduo sólido resultante contém fósforo, zinco e cálcio, entre outros nutrientes, o que sugere seu uso como fonte de macro e micronutrientes. O principal objetivo do presente estudo foi avaliar o uso do resíduo sólido como fertilizante agrícola, em experimentos de incubação em casa de vegetação, em amostras de dois solos: um de textura média e outro argiloso. A pequena alteração do pH do solo, em função da aplicação do resíduo, não constitui fator limitante à sua aplicação na agricultura. A evolução das concentrações de cálcio trocável, e fósforo e zinco extraíveis por Mehlich-1, em função do tempo de incubação, confirmam a potencialidade de uso do resíduo industrial como fertilizante agrícola.Termos de indexação: resíduo industrial, fertilizante agrícola, beneficiamento do caulim.

Acid sulfate soil in Malaysia is known to be very acidic with pH < 3.5 and have high amount of aluminum. A study was conducted to investigate the efficacy of various lime sources for alleviating the infertility of the soil and to determine its lime requirement. The treatments were ground magnesium limestone, hydrated lime, liquid lime and fused magnesium phosphate under submerged and moist condition for 3 months. Soil and water were sampled throughout the incubation period for the determination of pH, Al and Fe. The initial soil pH and exchangeable Al were 3.43 and 7.71 cmolc kg -1 , respectively. After 3 months of incubation under submerged condition, the soil pH and water pH increased from 3.43 to 5.01 and from 2.38 to 5.17, respectively. Under moist condition, the pH increased from 3.43 to 4.02 due to application of 6 t ground magnesium limestone (GML) ha -1 . The efficacy of hydrated lime as soil ameliorant was comparable to that of GML. It was recommended that 6 t ha -1 of GML be applied prior to the growing season for maximum benefit. This study showed that GML can be effectively applied to ameliorate the infertility of acid sulfate soils for rice cultivation.
