Nutrient management requirements
Basically farmers cannot do without general documentation on crop production measures. Detailed documentation is required simply for business planning alone. As a result data, which can also be used for the fertiliser planning, are produced. When it comes to cultivation planning and field management in arable farming, farmers use detailed field catalogues. In these catalogues all crops and measures are recorded and documented for each field individually. The quantity of fertilisers applied and the effects, arising from the organisation of crop rotation, can be displayed clearly. An analysis of soil samples is a sensible , in order to be able to make precise statements about the nutrient levels in the soils. This information can be used as an additional decision-making tool when preparing arable farming measures and creating fertiliser plans. In addition, a range of plant protection products, seeds and fertilisers with different properties is available. In addition to purchased goods, biogas and livestock farms also produce their own nutrients that are also used in crop cultivation. The properties of the fertilisers are included in the fertilisation planning, which is produced individually for each field. For organic fertilisers, there are specific provisions set out in the applicable directives. For this, the organic substances are inspected and the properties documented for internal use. In order to ensure that all crops have a sufficient supply of nutrients, farmers must take not only the nutrient needs of their crops into account but also the German Fertiliser Ordinance. It can be costly and time-consuming to coordinate these two factors. Farm Management Information Systems can help to lighten the workload: they display all the workflows on the farm and simplify fertilisation planning.
