Pelletized compost can be a superior alternative to phosphate fertilizer compared to bulk compost
© European Compost Network ECN e.V. (6/2014)
Manure is used as fertilizer and for soil amendment if handled appropriately, although it is the leading source of agricultural pollution if mismanaged. Because of the high water content, long-range haulage is uneconomical. Therefore, manure is mostly applied at high dose, close to the source, thereby diminishing its potential in soil amendment. Composting and pelletization facilitate manure exports, including storage, handling, and transport, for off-farm use and field application.

Estimation of biologically available heavy metal content of composts by various
extraction methods and ICP-OES multielemental detection
© European Compost Network ECN e.V. (6/2014)
The different fractionation protocols may offer different chemical information on biologically available element content of compost, however, only to the BCR sequential extraction scheme is available a sediment type certificated reference material for validation the fractionation procedure. For soils, composts CRM samples are available only for single step extraction or digestion procedures.

Effects of different biochars and combined biochar and anaerobic digestate utilization on rye-grass and soil properties in laboratory model experiment
© European Compost Network ECN e.V. (6/2014)
Recycling of organic wastes and preparation of added value products such as biochar or anaerobic digestate are challenges for a sustainable agriculture. Utilization of biochars to improve soil fertility and to mitigate global climate change is a popular research area. Residual of anaerobic digestion can be used as soil amendment as well, since it contains high amount of different macro-, and micronutrients mainly in water soluble form. Combination of digestate and biochars can cause various interactions, between digestate-biochar and soil system.

Effect of Intensity and Time of Aeration on Agrochemical Properties of Extracts from Vermicompost
© European Compost Network ECN e.V. (6/2014)
Vermicomposting is a completely environmentally friendly technology which converts biowaste to a value-added product. Extracts from vermicompost can be applied to plant surfaces and soils in ways not possible or economically feasible with solid vermicompost. The aim of this work was to determine the influence of aeration intensity and time of extraction on the agrochemical properties of aqueous extracts from two types of vermicomposts. Vermicomposts were made from horse manure (M) and apple pomace (P) waste.

Ecological and economic benefits of compost and digestate products
© European Compost Network ECN e.V. (6/2014)
European soils are systematically degrading. The European Soil Strategy urges more attention to the need for organic matter in soil: 45% of the soils in Europe show a lack of organic matter. This is also a problem in Flanders: almost 50% of the soils are below the target of organic matter. A range of measures is necessary for restoring the organic matter content: green manures, crop residues, organic fertilizer and soil improvers will all be needed. It is therefore of great importance that in the future sufficiently high amounts of quality composts and digestate products are produced, because these have shown to be excellent sources of stable organic matter and/or contribute to the soil fertility and food supply.

Agronomical valorisation of bovine slaughterhouse waste by aerobic composting: effects of the compost obtained on tomato (Solanum Lycoperscicum) germination and growth, variety of mongol-hybrid F1, in vegetation pots
© European Compost Network ECN e.V. (6/2014)
Compost originating in the mixture of household waste, chicken droppings and fish flour organic residues was used as an organic improvement in a tomato culture. The experimental device included 10 plots of 15 m2 each with 5 test plots and 5 check plots. All plots had received 30 kg of horse manure and the same amount of fish flour; only the test plots had received 7 tons of compost per hectare and had not been the object of phytosanitary treatment unlike the check plots that had been treated against nematodes and fungi.

The Technosols (TCNS) are “anthropogeomorphic material”, which includes those residues from anthropogenic activities, with similar characteristics to the geological and biogenic components of soils that can act as source material of them through the edaphogenesis processes.
