Collaborative project: Raising up the phoshor efficiency of slurry in the conventional und organic landusing systems. Subproject 1 (WiP)
Project
Project code: 2818100315
Contract period: 01.02.2017
- 31.01.2020
Budget: 188,866 Euro
Purpose of research: Applied research
While NIR-spectrometers for the measurement of liquid slurry are able to get a high precision gathering the nutrient content of “standard-slurry” from fattened pigs, dairy cows or slurry from biogases fed with renewable raw material, we need more samples for “special manure” with high or low nutrient content to get a better prediction by using the calibration model. To expand the measuring range during the project we were looking for liquid manure with a special content of dry matter, nitrogen, phosphor and potash all over Germany. Furthermore the nutrient sulfur as an additional parameter was integrated into the calibration model. In the end of the project work the measurement stability could be increased once more. From the practical view we can say that now we have a system for a specific and nutrient dependent application of liquid slurry and in addition we are able to quantify the nutrient flow in real time to get more acceptance from farms that take in manure.
