    Effect of long-term compost application on physical properties of loamy soils (2003) Seminar Proceedings: "Applying Compost – Benefits and Needs", Brussels, 22. - 23. November 2001 , S. 229-232.

    The benefit of a compost application not only derives from its nutrient effect, also very important is the effect of the supplied organic matter on pedobiological, especially pedophysical characteristics. The change in the pedophysical properties generally results from the cumulated effect of substantial amounts of humus, accumulated over a longer time period. Normally, the soil-improvement effects are more pronounced on sandy soils than on loam soils. However, the latter frequently exhibit problems as regards soil structure and erosion liability. In two field trials, the influence of compost application on pore volume, pore-size distribution and aggregate stability of fertile loess-loam soils was specifically studied (Lamp, 1996).

    Nutrition potential of biowaste composts (2003) Seminar Proceedings: "Applying Compost – Benefits and Needs", Brussels, 22. - 23. November 2001 , S. 117-128.

    Composts are important nutrient carriers. In Germany alone, with an estimated annual production of about 8 Mt (equivalent to 5 Mt DM), their nutrient potential represents almost 10 % of the phosphate, potash and lime currently applied as mineral fertilizers, as well as about 2.5 % of the mineral-fertilizer N applied in the whole German agriculture. To make efficient use of these nutrient amounts, composts require the targeted application as secondary raw material fertilizers (Gutser, 1997). Therefore, it is the aim of this paper to show the effects of macronutrients contained in biowaste composts, and to deduce general strategies for their use.

    Strategies for site-specific nitrogen fertilization with respect to long-term environmental demands (2003) Precision Agriculture, Wageningen Academic Publishers, Hrsg.: Stafford, J. and Werner, A , S. 193-198.

    Long-term field trials were implemented in three regions of Germany, differing in climatic conditions and soil properties, to evaluate different site-specific nitrogen fertilization approaches over several years with regard to N efficiency, yield and environment. The strategies tested were mapping approaches on the basis of site-specific yield potential and spectral information and, alternatively, an on-line approach using the Hydro N sensor. Results from the first year are presented. N efficiency could be increased by mapping approaches on sites with low yield potential. Total yield however was not noticeably affected. Sensor based N application reduced variability in the field but only slightly increased total yield. On the other hand, N efficiency was significantly reduced on shallow soils. The first results indicate that including yield potential in site-specific N recommendation could be an essential step to make plant nutrition more environmentally sound.
