Biochar is a carbon-rich material produced by pyrolysis, which is the thermal decomposition in the absence of oxygen. This usually occurs in organic biomass, such as wood, agricultural residues, or other plant materials. It is primarily used as a soil amendment to...
The biofertilizer contains primarily of beneficial microorganisms, including arbuscular mycorrhizal fungi (AMF), bacteria, and other fungi. These microorganisms are produced in vitro, in axenic cultures, and in vivo, resulting in effective inoculants. The AMF included...
Growing media include any materials other than soil used as a horticultural substrate for plant rooting and cultivation in a confined volume, as part of controlled environment agriculture. These growing media are used for growing vegetables, fruits and ornamentals in...
Biostimulants aim to improve the effectiveness of fertilization, the efficiency of plant nutrition. Their use is rather preventive. A plant biostimulant is a product that stimulates plant nutrition processes independently of the nutrients it contains, with the sole...
Small-scale anaerobic digestion of residual flows (mainly at dairy farms) can help the farmer to fulfil the electricity needs of the farm and partly the heat demand through combustion of biogas in a combined heat and power unit. It has a local character and limited...
Digestates are the majority by-product of methanization. They are rich in organic and mineral elements, giving them a high organic fertilizer potential. The spreading of digestates, particularly of agricultural origin, is the most commonly carried out practice in...
This good practice is inspired by a collaboration between farmers with a partnership with governments, and nature organizations called Agricycling. However, the initiative can be applied in many other places. It focuses on reusing available residual streams...
To ensure optimal nutrient use, it is important to guarantee the nutrient levels in animal manure before application. This approach is especially relevant for slurry and other processed forms of biobased fertilizers. By precisely determining the nutrient composition,...
Stripping-scrubbing of the liquid fraction of pig manure allows for on farm production of biobased fertilizer. It starts with the liquid fraction of pig manure followed by scrubbing for ammonium salt recuperation. The operating principle of stripping-scrubbing is that...
Emissions of NH3 from livestock housing and slurry storage represent a large part of the total NH3 emissions from agricultural activities. Therefore chemical air scrubbing is used to reduce the ammonia and odor components in stable air. Water with added sulfuric acid...
Municipal sludge is a large source of nutrients. Unlike other organic fertilizers, municipal sludge has a stable composition, enabling precise adjustments to mineral fertilization. Nitrogen in organic fertilizer is available in different ways, and depending on which...
Since 2022, it is mandatory in Spain to have a recent product analysis when applying organic fertilizers. However, this is not yet a common practice among farmers. Pig slurry, as a widely used organic fertilizer, play an important role in the fertilization strategy of...
Cut and carry fertilizers are organic fertilizers produced from plants. Those plants are often leguminous species. The plants are grown in one place and, after being harvested, transported to another location and applied as fertilizers. In between they might be dried...
Depending on the crop, crop residues can contain considerable amounts of nutrients. The nutrients are for instance stored in leaves, which are after being harvested left on the field. When degrading, those nutrients become available for soil organisms and the...
