Nitrogen Balance And Soil Nitrates In Suckler Cow Pastures Fertilised With Mineral Fertiliser, Pig Slurry Or Cattle Compost, Isabelle Dufrasne, J. F. Cabaraux, L. Istasse, J. L. Hornick
Nitrogen Balance And Soil Nitrates In Suckler Cow Pastures Fertilised With Mineral Fertiliser, Pig Slurry Or Cattle Compost, Isabelle Dufrasne, J. F. Cabaraux, L. Istasse, J. L. Hornick
IGC Proceedings (1997-2023)
A code of good practice was established by each European member state according to the EU Nitrate Directive. In Belgium, the nitrogen (N) inputs on pastures from slurry or compost are limited to 210 kg N/ha. Bigger quantities can be applied if the farmer follows a programme of additional measurements, including soil nitrate (NO3) analysis. This investigation aimed to measure animal performance, N balance and soil NO3 in pastures fertilised with mineral N, pig slurry or cattle compost, the pastures being grazed by Belgian Blue cows and their calves.
Agronomic Characterisation Of Sewage Sludge: Residual Effects, M. R. Mosquera-Losada, A. Rigueiro-Rodríguez
Agronomic Characterisation Of Sewage Sludge: Residual Effects, M. R. Mosquera-Losada, A. Rigueiro-Rodríguez
IGC Proceedings (1997-2023)
The progressive implementation of the EU Urban Waste Water Treatment Directive 91/271/EEC is increasing the quantities of sewage sludge requiring disposal. Agronomic use of sewage sludge should be based on crop fertiliser requirements and heavy metals content. Sewage sludge fertiliser potential depends on the stabilisation treatments of sewage sludge: composting, anaerobic digestion, aerobic digestion or pelleting (EPA, 1994). The objective of this experiment was to evaluate the fertiliser effectiveness and residual effects of three types of sewage sludge treated in three different ways.
Biological Indicators Of Compost-Mediated Disease Suppression Against The Soilborne Plant Pathogen Rhizoctonia Solani, Lynn Fang
Graduate College Dissertations and Theses
Compost can suppress soilborne plant pathogens that cause significant damage on globally important food crops. However, reports of plant pathogen suppression are inconsistent likely because there are no established standards for feedstock material, application rate, and maturity age upon application. Excellent results can be achieved in greenhouse trials, but field applications are much less reliable. Disease suppression occurs through the activity of biocontrol organisms (direct antagonism), and general microbial competition. Biocontrol species are hypothesized to colonize the pile during the curing phase, but single species may not be as important as microbial consortia. Substrate composition during maturation may give rise …
