To determine inactivation of Cryptosporidium parvum oocysts and reduction of Escherichia coli and enterococci in cattle slurry added aqueous ammonia. Escherichia coli, enterococci and nonviable C. parvum oocysts (DAPI+PI+) were enumerated every second day for 2 weeks in cattle slurry amended with 60 mmol l-1 aq. ammonia and compared with untreated ...

Het ministerie van LNV wil duidelijk hebben of mestvergisting bij kan dragen aan de klimaatdoelstellingen waar de landbouw aan moet voldoen. De vraag is of mestvergisting kan bijdragen aan de reductie van broeikasgas- en ammoniakemissie, wat het (lange termijn) effect is op de organische stofopbouw en of het toevoegen van extra organisch materiaal ...

Dit rapport gaat in op de vraag: heeft het zin dat melkveehouders niet op het eigen bedrijf plaatsbare rundveedrijfmest bewerken, of is het beter om deze onbewerkt af te zetten naar akkerbouwers? De economische waarde van tien verschillende mestproducten zijn geëvalueerd vanuit het perspectief van de melkveehouder en akkerbouwer. De opbrengsten be...

In this study, we tested the high-solids thermophilic anaerobic digestion of separated cattle slurry solids inoculated by liquid digestate collected from the 1st stage of the wet process operated in an agricultural mesophilic biogas plant. The process without batch agitation (stirring) was carried out in a barrel bioreactor located in the incubator...

A simple empirical model was developed for estimation of net mineralisation of pig and cattle slurry nitrogen (N) in arable soils under cool and moist climate conditions during the initial 5 years after spring application. The model is based on a Danish 3-year field experiment with measurements of N uptake in spring barley and ryegrass catch crops,...

The paper presents the results of the model of anaerobic co-fermentation of cattle slurry with biscuit waste. It was confirmed that the waste from the food industry is a valuable biogas substrate. The highest specific production of methane (0.49 mN3·kgVS-1) was achieved in the co-fermentation of 20 wt% biscuit waste with cattle slurry. The feed mix...

The use of positioned mineral fertilizer phosphorus (P) starters reduces the risk of yield penalties in maize production. However, it also increases the soil P surplus and attendant risk of P losses to the environment, in particular on farms with ample supplies of livestock manures. We examined whether routine applications of starter P can be refra...

Beoordeling van de mogelijke werking van het AGRITON systeem om ammoniakemissie uit rundveestallen tegen te gaan. De maatregel behelst het op regelmatige basis toevoegen van een middel aan verse rundveedrijfmest in de mestkelder.
