“…Liming enhances plant- ions from the soil adsorption sites resulting in increase in soil pH. Therefore, the increase in soil available P could be due to the reduction in phosphorus fixation by Al and Fe oxides effected of lime (Kisinyo et al, 2012;Ziadi et al, 2013). Data presented in Table 4 indicate that the amounts of plant-available P taken up by the plants in acid soil were quite small -186 mg kg -1 P 2 O 5 , or 20.8% of total P (Table 4).…”

Investigations on phosphorus (P) distribution in a naturally acid and limed moraine loam, Bathypogleyic Dystric Glossic Retisol were conducted in a site of a long-term experiment at the Vėžaičiai Branch of Lithuanian Research Centre for Agriculture and Forestry in 2008 and 2011. The aim of the present study was to determine the distribution of different phosphorus forms and fractions in naturally acid soil limed for a long time (62 years). During this study different amounts (18.4 and 104.9 t ha -1 ) of lime materials were incorporated into the soil and affected the formation of two soil pH KCl levels -acidic (5.6) and near to neutral (6.7). Seven different organic and mineral phosphate fractions and plant-available phosphorus were determined in the soil. The long-term soil liming was found to have no significant effect on the total P content and its distribution, but caused the changes in the proportions between the different phosphorus forms. Major part of mineral (74.02-83.68%) and organic (88.9-93.8%) P was composed of Al and Fe phosphates. Soil liming using ×2.0 liming rates every 3-4 years influenced a significant increase of the phosphates (AlPO 4 and Al(Fe)PO 4 ) little-available to plants obtained by the second cycle of extraction. It was determined that when soil pH becomes near to neutral, water soluble and plant-available P increases compared to its value measured at native pH. Increase of soil pH KCl till 6.7 had a significant effect on the amount of little plant-available Ca phosphates and less soluble organic phosphorus fraction amount in soil. The relatively optimal amounts of phosphorus fractions available for plants were determined in the soil with a pH KCl of 5.6, achieved by liming with a 0.5 rate every 7 years.

“…In low P acids soils with high P sorption, use of both P fertilizer and lime have been suggested for maximum soil available P and efficient utilization of the P fertilizers by plants The et al, 2006). Many studies have reported improved soil available P and its utilization due to combined applications of both lime and P fertilizer on Kenyan acid soils (Kanyanjua et al, 2002;Kisinyo, 2011;Kisinyo et al, 2012;Opala et al, 2014). Therefore, it is imperative that combined application of both P fertilizer and lime are important for both short and long term management of P deficient acid soils such as found in Kenya.…”

“…Elsewhere in tropical acid soils, residual effect of P fertilizer has been reported to persist for as long as 5 to 10 years or more, depending on the initial P rate applied crop removal and the soil buffering capacity (Tisdale et al, 1990). Combined application of both lime and P fertilizer has increased soil available P, seedlings growth and crop yields more than either of them alone in Kenyan acid soils (Kisinyo, 2011, Kisinyo et al, 2012Kanyanjua et al, 2002). In low P acids soils with high P sorption, use of both P fertilizer and lime have been suggested for maximum soil available P and efficient utilization of the P fertilizers by plants The et al, 2006).…”

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.

“…Under these situations, an appropriate combination of lime and P is an important strategy for improving field crops yield in highly weathered soils. Several workers have tested and documented the effect of liming on nutrient availability in acid soils of the western highlands of Kenya [22,24,25]. However, information on the interaction of lime, Al and P to ensure optimal availability of P as assessed by plant uptake in Kenya highlands soils is limiting.…”

“…Kenyan soils, similar to other agricultural soils of the tropics, have low available P, high Al concentrations and high P-fixation capacities [21,22,23] attributable to extensive weathering and dominance of Al, Fe, and Mn oxyhydroxides and 1:1 layer silicates and extensive leaching of the basic cations and high concentration of Al 3+ and Fe 3+ in the soil solution and on the cation retention sites and the soil colloids. Under these situations, an appropriate combination of lime and P is an important strategy for improving field crops yield in highly weathered soils.…”

Soil acidity and phosphorus (P) deficiency are some of the major causes of low maize yields in Kenya. Although considerable work has been done to establish liming rates for acid soils in many parts of the world, information on the effects of the lime-Al-P interactions on maize growth and yield is limiting. A green house pot experiment was conducted at Waruhiu Farmers Training Centre, Githunguri to evaluate the effects of lime-Al-P interactions on maize growth and yield in acid soils of the Kenya highlands. Extremely acidic (pH 4.48) and strongly acidic (pH 4.59) soils were used for the study. Four lime (CaO) rates and phosphorus (Ca (H 2 PO 4 ) 2 rates were used. The liming rates were: 0, 2.2, 5.2 and 7.4 tonnes ha -1 for extremely acidic soil and 0, 1.4, 3.2, and 4.5 tonnes ha -1 for the strongly acidic soil. Phosphorus applications rates were: 0, 0.15, 0.30 and 0.59 mg P kg -1 soil for the extremely acidic soil and 0, 0.13, 0.26, and 0.51 mg P kg -1 for strongly acidic soil. The experiments were a 4 2 factorial laid down in a Randomized Complete Block Design (RCBD) and replicated three times. Data collected included: plant height, number of leaves, P-uptake and maize dry matter yield. Lime-Al-P interaction significantly (P≤ 0.05) increased P concentrations in maize tissues, maize height, dry matter yields. Use of 7.4 tonnes ha -1 in extremely acidic soils and 4.5 tonnes ha -1 in strongly acidic soils significantly (P≤ 0.05) increased maize height compared to lower lime rates. Phosphorus uptake and dry matter yields did not however, vary when 7.4 tonnes ha -1 lime was combined with either 0.59 mg P kg -1 or 0.3 mg P kg -1 in extremely acidic soils, and 4.5 tonnes ha -1 was combined with either 0.51 mg P kg -1 or 0.26 mg P kg -1 in strongly acidic soils. It was, therefore, concluded that lime and P positively interact to reduce Aluminium toxicity in the soils and improve maize growth, P uptake and yields in acid soils in the Kenya highlands. However, further research is required to evaluate long term effects of the interactions on crop yields, uptake of plant nutrients under field conditions.
