Flora on arable lands

Weed flora on arable land plays an important role in maintaining of overall biodiversity of agroecosystems. Weed control influence the food chains associated with invertebrates and birds. Intensive farming is considered to be the main cause of the reduction of weed species diversity and abundance in agroecenosis.

The aims of the study:

1. The assessment of weed flora diversity on arable land in organic and conventional farms;

2. The analysis of the impact of agricultural practices used in both types of farms on the weed flora diversity;

3. Preparation of the recommendations for changes in the agri-environmental programs to increase the diversity of weed species and encourage the protection of rare, threatened species;

4. The establishment of the basis for monitoring of the flora diversity on arable land.

Methodology of research

The research of weed flora on arable land are carried out within the 28 squares of 10 hectares (14 squares with a dominant share of organic farming and 14 squares with a dominant share of conventional agriculture), located in Lublin province, established for the Project KIK/25. The study will be carried out in 2012- 2015, in the fixed monitoring points. Moreover the assessment of the diversity of weed flora in spring cereals are conducted. In 2013 the floristic inventory of all research squares will be done. In addition, the questionnaire surveys in organic and conventional farms, which are engaged in flora monitoring, are carried out.


Inventory and monitoring of flora on arable land are conducted by the Institute of Soil Science and Plant Cultivation - National Research Institute in Puławy.
