 Abstract_text_2 : 
  The long - term experiment ( LTE ) " International Organic Nitrogen Fertilisation Trial " ( IOSDV ) Rauischholzhausen ( University Gießen ) was set up in 1984 as part of an internationalseries of trials which were started simultaneously at about 15 locations in several European countries . The initiator of this series of trials was Eduard von Boguslawski , who also foundedthe international working group " IOSDV " . The LTE " IOSDV " in Rauischholzhausen was later continued and managed by Bernd Honermeier ( 1996 - 2021 ) . The original idea of this LTE was to compare three farming systems ( farm types ) , ( 1 ) system without organic fertilisation ( simulating a cash crop farm ) , ( 2 ) system with organic fertilisation from livestock ( farmyard manure , simulating a farm with livestock ) and ( 3 ) system with organic fertilisation from plant residues ( straw , catch crops and digestate from a biogas plant ) . In these arable farming systems , the classic cash crops sugar beet ( since 2010 silage maize ) , winter wheat and winter barley are grown in a crop rotation ( one after the other in time ) and at the same time also next to each other every year . Due to the central importance of nitrogen as a plant nutrient , mineral N fertilisation was included as a test factor and combined with all other test factors in four different dosages so that possible interactions could be investigated . Since the LTE was set up at several locations , the influence of site and climatic conditions on soil properties and plant yields as a function of organic and mineral N fertilisation can also be investigated . The trial was extended in 1997 by a variant with " compost fertilisation " ( without and with certified compost ) , with the same crop rotation and mineral N fertilisation . Land Use Type : Field crops Research Theme : Fertilization LTE Category : Fertilization Farming Category : Conventional Research Parameter : -Plant : total biomass yield , grain yield , harvest index -Soil : Ct , Corg , Nt , nitrate N Factors : - Factor A : Crops ( sugar beet / maize , winter wheat , winter barley ) - Factor B : N - fertilization ( 5 levels ) - Factor C : Organic fertilization ( 3 levels ) Research question : The trial aims to clarify the long - term effects of different organic fertilisation ( manure from livestock compared to organic matter from plants ) on soil properties ( Ct / Corg , Nt , Nmin ) and on biomass yields of maize , winter wheat and winter barley . It should also be clarified whether there is an interaction between organic fertilisation and mineral N fertilisation as well as between fertilisation and site conditions regarding soil parameters and plant yields and whether these factors thus influence each other .
