Abstract
The study aimed to investigate the effectiveness of biochar application on fertile soils in a temperate climate during the first year of application. The field trial was conducted on a nutrient-rich silt loam soil at two experimental sites in north-eastern Slovenia (Biš and Skorba). The effect of biochar applied alone or in combination with compost or mineral fertiliser on soil properties and yield of white cabbage was studied. In addition to the control (C), the soil received five treatments including biochar (B; 1.5 t/ha), compost (CO; 1.5 t/ha), biochar-mixed compost (BCO; 3.0 t/ha), standard mineral fertilisers (NPK; NPK 0.35 t/ha, potassium sulphate 0.25 t/ha and calcium ammonium nitrate 0.25 t/ha) and combined application of half the amountof NPK and BCO (NPK+BCO). The results showed that the applied treatments had no significant influence on the measured soil chemical parameters, except for the amount of total organic carbon, electrical conductivity and pH in Biš and total carbon in Skorba. All investigated parameters (cabbage head weight, head circumference, total and market yield) were higher at the experimental site Skorba. Statistically significant differences were found only at the experimental site Biš, where the treatment influenced all parameters (p < 0.01), except for the head circumference of the cabbage. The NPK and NPK+BCO treatments produced significantly higher total yields (66.7 t/ha and 65.8 t/ha, respectively) and marketable yields (53.2 t/ha and 51.8 t/ha, respectively) compared to the other treatments (41.3-52.6 t/ha and 30.5-42.4 t/ha, respectively). Although the differences between the other treatments were insignificant, a trend of decreasing cabbage yields towards CO > BCO > B was observed. Similar results were also obtained when analysing the average data of the two experimental sites.

期刊介绍:
Chinese Agricultural Science is a comprehensive, academic journal co-sponsored by the Chinese Academy of Agricultural Sciences and the Chinese Society of Agriculture. Founded in 1960, the journal is published publicly in the form of a bimonthly magazine. The contents of the journal include crop genetic breeding, cultivation, plant protection, soil fertiliser, horticulture, food science and engineering, animal husbandry and veterinary medicine, etc. It aims to promote the sustainable development of high-yield, high-quality, high-efficiency and environmentally friendly agriculture and animal husbandry.
The aim of the journal is to report on the scientific research results of agriculture and animal husbandry in China, to enhance the innovation capacity of agricultural science and technology, to promote academic exchanges at home and abroad, and to serve the development of modern agricultural science and technology and scientific and technological progress. In addition, Chinese Agricultural Science is included in several international retrieval systems, including American Chemical Abstracts CA, Scopus, GeoBase, Russian Journal of Abstracts, CABI (Centre for Agricultural and Biological Information International) of the United Kingdom, and AGRIS (Food and Agriculture Organization of the United Nations).
