Latvia is characterized by variation among farms. Analysis of the dynamics of weed diversity is based on monitoring sowings during 1997–2004 in westerly and central regions of Latvia. The aim of this research was to compare the dynamics of weed on unchanging types of grain sown, fields with elevated grain density and un-utilised agricultural land. Two hypotheses were put forward: the dynamic of several species of weeds to impact the total number of weeds in land laying waste (un-utilised agricultural land), and the increase in the numbers of several specific weeds in fields with elevated grain density using annual herbicides.
