nutrient content - Opis:
- The aim of this study was to evaluate the content of soil elements and parameters such as pH and iodine value in a period of one vegetation cycle. Soil samples were collected from the topsoil to a depth of 30cm, in April – before spring fertilization, August - after the summer harvest and October – before winter fertilization 2014. During the whole research period soils showed on average, a slightly acidic pH (5.6-6.2). The increase in calcium concentration leads to decrease in aluminum concentration, which at the highest content is in the range 1,02 mg/100 g and does not exceed the allowable concentration. However, increasing the sodium amount and magnesium concentration causes the decrease of potassium concentration and iodine value. In the central-eastern region dominate brown soils characterized by a lower iodine value (LJ) than in the south-western region where occurrendzina and pararendzina. The low level of nutrient microelements in studied soils obliges farmers to phosphorus fertilization and potassium supplement in order to obtain expected yields.
