As an essential nutrient for food production, phosphate is largely used in fertilizers to enhance crop growth (Baishya et al., 2016; Hasanuzzaman et al., 2018). Regardless of its enormous demand, the only concentrated P source is phosphate rock and the resource is finite (Cordell & White, 2011; Smit …

Organic farming is increasingly promoted as a means to reduce the environmental impact of artificial fertilizers, pesticides, herbicides, and antibiotics in conventional dairy systems. These factors potentially affect the microbial communities of the production stages (soil, silage, dung, and milk) of …

n the work package described in this report, members are investigating whether a cooperative of farmers can become self-sufficient in energy and fertilization by using manure and organic waste flows in combination with anaerobic fermentation. The aim is to link the nutrient cycle (from manure to digestate …

Wastewater consists of valuable nutrients that can be reused in agricultural fertilizers. In order to capitalize on this reuse potential, a transition is needed to circular sanitation-food systems. This poster summarizes Martijn Stehouwer's MSc thesis in enironmental policy. This thesis seeks to understand …

The 'AgroCycle' project investigates whether a cooperation of farms can become self-sufficient in energy and fertilization by using manure and organic waste streams for the production of energy, green fuel and green fertilizers by means of anaerobic digestion (AD). In the project, the project partners …

The dairy sector in the Netherlands aims for a 30% increase in efficiency and 30% carbon dioxide emission reduction compared to the reference year of 1990, and a 20% share of renewable energy, all by the year 2020. Anaerobic Digestion (AD) can play a substantial role in achieving these aims. However, …

Europe in general and Romania specifically has been increasingly a target of foreign and domestic investors. Due to its cheap land prices and agricultural policies supporting largescale agricultural investments Romania has become a country with high risks concerning land grabbing. However, the academic …

ICL Fertilizers Europe C.V. has been trying to substitute ammonium sulfate with urea as nitrogen source in the fertilizer granules because urea has a higher mass percentage of nitrogen and is relatively cheaper. Several methods have been tested, including methods from previous experiments. The most …
