Changes in Selected Forage Parameters of Meadow Timothy (Phleum pratense L.) Biomass and in the Soil as a Response to Slurry Interaction with Soil Conditioners

The aim of the research was to assess effect slurry and soil conditioners on Phleum pratense yield its selected parameters nutrients. second aspect experiment obtain information whether applied together will increase accumulation nitrogen, phosphorus potassium in compared own or with NPK fertilizers. carried out basis a three-year (2015–2017) field experiment. interaction mineral fertilizers tested forage grass Meadow timothy species Secesja variety, sown autumn 2014. Grass total protein, crude fiber ash content net energy concentration (NE) were determined; additionally, at end experiment, measured. results plant material analyses statistically developed using three-factor analysis variance, while determination one-factor analysis. Humus Active Rosahumus significantly increased amount meadow biomass relation plants fertilized (by 22% 26%, respectively) supplemented 9% 7%). conditioner resulted significant 5% 6.5%). did not result protein Soil nutrient determined after proved impact potassium.
