abstract: Although organic fertilisers always contain micronutrients, we have to pay attention to the question of whether continuous fertilisation will lead to lower contents in plants or lower availability in the long run. We investigated topsoil samples from long-term trials with farmyard manure and mineral fertili-sation and with different organic and conventional farming systems. Input of micronutrients via or-ganic fertilisers was obviously more significant in the case of poor sandy soil than in that of loamy soil with high total contents and higher mineralising potential.
