. 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.

Abstract:A study was conducted to determine the efficacy of applying ground magnesium limestone (GML) or ground basalt in combination with bio-fertilizer to sustain rice production on an acid sulfate soil in Malaysia. Soils from Kelantan Plains, Malaysia, were treated with GML, ground basalt, bio-fertilizer, GML + bio-fertilizer, and ground basalt + bio-fertilizer (4 t¤ ha ¡1 each). Results showed that soil fertility was improved by applying the soil amendments. GML and basalt contain some Zn and Cu; thus, application of these amendments would increase their contents in the soil needed for the healthy growth of rice. Basalt applied in combination with bio-fertilizer appeared to be the best agronomic option to improve the fertility of acid sulfate soils for sustainable rice production in the long run. In addition to increasing Ca, Mg, Zn, and Cu reserves in the soil, water pH increased and precipitated Al 3+ and/or Fe 2+ . Ground basalt is cheaper than GML, but basalt dissolution in the acidic soil was slow. As such, its ameliorative effects could only be seen significantly from the second season onwards. The specially-formulated bio-fertilizer for alleviating the infertility of acid sulfate soil could also enhance rice growth. The use of the bio-fertilizer fortified with N 2 -fixing bacteria is a green technology that would help reduce NO 3 ¡ and/or NO 2 ¡ pollution and reduce the cost of rice production. The phosphate-solubilizing bacteria (PSB) present in the bio-fertilizer not only increased the available P, but also helped release organic acids that would inactivate Al 3+ and/or Fe 2+ via the process of chelation.

“…Submerging the soil is another way of decreasing the acidity. GML application is known to increase soil pH that precipitate Al as Al-hydroxides (Shamshuddin et al, , 1998Ismail et al, 1993;Shamshuddin and Ismail, 1995).…”

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.
