| The potential of different plant based organic fertilisers (PBOF) to substitute animal based organic fertilisers (ABOF) in organic vegetable production were investigated in incubation, pot and field experiments. PBOFs have the potential to replace ABOFs. Particularly legume seed meals show fast net N-release even at low soil temperatures. Considerable differences in nitrate contents of vegetables can be found between the different fertilisers although fresh matter and N yields are nearly identical. |

| For a given organic farm with livestock and vegetable production in Southern Germany the economic viability of on farm produced legume seed meal as Plant Based Organic Fertiliser (PBOF) is analysed by means of a Linear Programming (LP) model in order to asses under which conditions such a fertiliser use may be profitable. Yields, labour demand and gross margins of the different farming activities are taken from data collections and adapted based on information provided by the farmer, whose specific crop rotation, labour and stable restrictions are also implemented in the LP model. Nitrogen supplies and demands of the different farming activities are drawn from data collections and information by plant scientists. Our calculations show that legume seed... |
