Two genotypes of white clover (Trifolium repens L.) selected for either tolerance or sensitivity to soil aluminium (AI), were grown in an acid soil with factorial combinations of four Al and four phosphorus (P) levels. Plants of the AItolerant genotype were larger and leafier than the susceptible plants despite containing more AI. Shoot Al concentrations were lower in the tolerant plants. Al x P interactive effects on growth were normal, with P ameliorating the effects of increased AI. Shoot and root magnesium (Mg) levels were much higher in the tolerant plants suggesting that in white clover, as for some other species, Mg plays a key role in Al tolerance. Increasing Al application rates from 20 to 50 Ilg Al/g soil stimulated several of the plant growth parameters that were recorded but the mechanism was not apparent. The AI-tolerant genotype had a lower shoot P concentration and shoot P content and was more responsive to applied P than the susceptible genotype. These characteristics which are associated with improved P efficiency in white clover, suggest that screening white clover for Al tolerance may produce plants well adapted to acid soils and intermittent P fertiliser use.

“…Acidic soils usually have toxic levels of Al, which are associated with P deficiencies, and these greatly limit plant growth (Clark 1977;Olsen and Sommers 1982). The relatively increased P uptake by maize for the biochar-amended soils could be due to reduced Al toxicity.…”

Effects of biochar and/or dolomitic limestone application on the properties of Ultisol cropped to maize under glasshouse conditions

. 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.

“…Although the approach of using tolerant plant germplasm is not able to reverse soil acidity conditions, it minimizes the problems experienced by farmers, especially those who do not use lime (Clark, 1997). In recent studies, Kenyan maize and sorghum germplasms tolerant to Al toxicity and /or P use efficient have been identified (Ouma et al, 2013;Ligeyo, 2007;Matonyei, 2010;Too, 2011).…”

This review focused on the efforts made to understand and manage Kenyan acid soils by use of inorganic, organic materials (OMs) and crop germplasms tolerant to soil aluminium (Al) toxicity and/or low soil available phosphorus (P). Kenyan acid soils which occupy 13% of the total land area were developed through parent materials of acid origin, leaching of base cations and use of acid forming fertilizers. They are high in Al (>2 cmol Al/kg and > 20% Al saturation) and low in soil available P (< 5 mg P/kg soil) due to moderate-high (107-402 mg P/kg) P sorption, hence crops recover only 9.6 to 13.5% of the P fertilizer. Application of lime, P fertilizer and OMs increases soil pH, available P and reduces Al toxicity on Kenyan acid soils. Lime, P fertilizers and OMs have increased maize grain yield by 5-75, 18-93 and 70-100%, respectively on Kenyan acid soils. Similarly, deployment of crop cultivars tolerant to Al toxicity and/or low soil available P increases crop yields. However, lack of knowledge on the importance of lime, credit to purchase farm inputs, crop varieties tolerant to soil acidity constraints and inadequate amounts of OMs limits crop yield on Kenyan acid soils.
