초록

Soils in continuous monoculture cropping system generally have a number of physical and chemical problems. Thus, we studied to investigate selected soil properties in continuous watermelon cropping plots with applications of different soil management practices: 1) conventional farming practice (CFP), 2) chemical fertilizer management practice (FMP), the FMP with different amounts, 0.5, 1.0, and 1.5 t ha-¹, of oyster shell meal application (FMP-OS 0.5, 1.0, and 1.5 t ha-¹), and 3) the FMP with different amounts, 2.0, 3.0, and 4.0 t ha-¹, of peat application (FMP-PT 2.0, 3.0, and 4.0 t ha-¹) and also to evaluate watermelon quality. Soil pH slightly increased only in the FMP-OS 1.5 t ha-¹ plot, while it was not changed or decreased a little in other plots. The contents of soil organic matter (SOM) expectedly increased in the FMP-PT plots, whereas it markedly decreased in the FMP-OS plots. The concentrations of exchangeable cations, Ca²+, Mg²+, and K+, in soils were mostly dropped down in most of the FMP and FMP-PT plots. Otherwise, the exchangeable Ca2+ concentration increased a bit in the FMP-OS plots. Also, the concentrations of water-soluble anions, NO₃-, Cl-,SO₄²-, and PO₄³-, in soils mostly declined in all the plots applied with the different management practices during the study years. Due to the cation and anion decreases, the electrical conductivity (EC) values in the soils were greatly reduced in the plots. Thus, the soil management practices applied, especially oyster shell meal and peat treatments, might be useful to control soil conditions. However, watermelon quality, such as sugar content and fruit weight, would not be associated with the soil management practices applied.
