Different fertilizers may affect soil enzymatic activity and soil fertility dynamics. These effects were investigated in a field experiment with cucumber (Cucumis sativus L.) and the relationship with yield and soil nutrient availability was assessed. Soil enzymatic activity, measured as phosphatase, catalase, invertase and urease activities, decreased in the early growth stages of cucumber, but increased...
This study was carried out to evaluate the correlations between soil physico-chemical properties and onion (Allium cepa L.) plant nutrients in a long-term onion producing area over 30 years, during the growing season of 2010–2011. Soil and plant samples were collected from 16 onion growing fields. Each mineral content of onion plants showed different trends in conversion from the initial bulbing stage...
