Abstract
Studies on the Effects of Liming Acidic Soils on Improving Soil Chemical Properties and Yield of Crops: A Review
Highlights
Soil acidity is one of the main factors that limit and prevent sustained agricultural productivity and production in many parts of the world (Sumner and Noble, 2003)
Soil acidity affects the growth of crops because acidic soil contain toxic levels of aluminum and manganese and characterized by deficiency of essential plant nutrients such as P,N, K, Ca, Mg, and Mo when the soil pH falls below 5.5; and the plant root system is affected by high Al concentrations because of Al interferes with the uptake, transport, and utilization of essential plant nutrients such as P, K, Ca, Mg, and water, as well as enzyme activity in the roots (Wang et al, 2006; Lofton et al, 2010; M Abdulaha-Al Baquy et al, 2016)
The results showed that the highest significant grain yield and biomass yield were recorded by application of 1.65 and 2.2 t ha-1 lime
Summary
Soil acidity is one of the main factors that limit and prevent sustained agricultural productivity and production in many parts of the world (Sumner and Noble, 2003). It is estimated that approximately 50% of the worlds’ arable soils are acidic and may be subjected to the effect of aluminum (Al) toxicity of which the tropics and subtropics account for 60% of the acid soils in the world (Sumner and Noble, 2003). It is mostly distributed in developing countries, where population growth is fast and demands for food and fiber is increasing. This review article is presenting the causes and forms of soil acidity and lime treatment of acidic soil with the objective to review the effect of lime treatment of acid soil on soil chemical property and crop performance
