Effect of the liming on the soil chemical properties and the development of tomato crop in Sucre- Colombia

Abstract

The acidity of the soil produces complex interactions on plant growth limiting factors that involve physical, chemical and biological properties of the soil, which can manifest in deficiencies of calcium, magnesium and phosphorus and toxicity of aluminum, iron, and manganese, which could limit plant growth. Based on the above and in order to contribute to better development of tomato crop in soils with a low nutritional offer and acid reaction of the Santa Clara region (Sucre), the following research has been proposed with five (5) commercial lime dose (0, 1, 2, 3 and 4 t ha -1 ) and its effect on chemical properties, using tomato as an indicator plant. The effect on pH, P, Ca, Mg and K in the soil was evaluated, and in the plant, the yield components were evaluated (weight and dimensions of the fruit, yield). A completely randomized design with three repetitions was used, the information was processed with the statistical software SAS version 9.1. It was found that liming improves soil pH, availability of P, Ca, Mg and K, in the same way, the development and yield of tomato crop with doses of up to 3 t ha -1 of lime on the soil is improved.
