| Pratiche di agricoltura intensiva hanno condotto alla degradazione della risorsa suolo, vale a dire ne hanno diminuito la qualità. Più precisamente, la degradazione riguarda la riduzione della sostanza organica, della stabilità strutturale e della disponibilità di nutrienti nel suolo, con conseguente decremento della produttività. All’interno di un progetto di ricerca in corso, relativo a produzione e impiego di compost in agricoltura biologica, sono previste analisi di fitotossicità su sansa umida denocciolata (SD) poi impiegata in una rotazione farro-cece. L’obiettivo della ricerca è quello di verificare come l’incorporazione al suolo di matrici organiche (M), anche tal quali, può concorrere a mantenere o incrementare la fertilità del suolo ed a... |

| Utilizing animal slurry to produce biogas may reduce fossil fuel usage and emissions of greenhouse gases. However, there is limited information on how the recycling of digested slurry as a fertilizer impacts soil fertility in the long run. This is of concern because organic matter in the slurry is converted to methane, which escapes the on-farm carbon cycle. In 2010, a study of this question was initiated on the organic research farm in Tingvoll, Norway. So far, a biogas plant has been built, producing anaerobically digested slurry to be compared with undigested slurry in perennial ley and arable crops. Effects on crop yields, soil fauna, microbial communities, soil structure, organic matter and nutrient concentrations are measured. |

| Eine wirtschaftlich tragbare Lagerung und zeitgerechte Nutzung von flüssigem Gärgut aus der fest/flüssig Trennung, dem sogenannten Presswasser ist schwierig. Das Projekt „Qualitätssteigerung Gärgut flüssig (Presswasser)“, das durch das BFE finanziert ist, will Alternativen für die landwirtschaftlichen Nutzung aufzeigen. Gemüsebaukulturen haben einen relativ hohen Nährstoffbedarf. Speziell im bio Gemüsebau stellt dies bedeutende Kosten dar. Die Möglichkeit, handelsüblichen bio Dünger mit aufbereitetem flüssigem Gärgut zu ersetzen soll hier in einem Feldversuch unter Praxisbedingungen untersucht werden. In diesem Teilprojekt wurde somit die Wirksamkeit des flüssigen Gärguts auf das Wachstum von Knollensellerie, im Vergleich zu herkömmlichem, kommerziellem... |

| A microarray spotted with 369 different 16S rRNA gene probes specific to microorganisms involved in the degradation process of organic waste during composting was developed. The microarray was tested with pure cultures, and of the 30,258 individual probe-target hybridization reactions performed, there were only 188 false positive (0.62%) and 22 false negative signals (0.07%). Labeled target DNA was prepared by polymerase chain reaction amplification of 16S rRNA genes using a Cy5-labeled universal bacterial forward primer and a universal reverse primer. The COMPOCHIP microarray was applied to three different compost types (green compost, manure mix compost, and anaerobic digestate compost) of different maturity (2, 8, and 16 weeks), and differences in the... |

| Good quality transplants are vital to growers for a number of reasons. Their ability to better tolerate pest, disease and weed problems and their capacity to make better use of newly incorporated green manures (compared to direct drilling) make them all the more so in organic systems. The availability of high quality growing media is essential to producing healthy vigorous plants, but the organic standards restrict the choice of products available and many growers do not feel they have sufficient information to base their choices. OCW, with support from Farming Connect, coordinated a project to assess the certified products and looked at a green waste based product under development to help address this problem. Growers were supplied with samples of... |

| The application of sewage sludge to agricultural land, a common practice to recycle nutrients in the past, is currently prohibited in organic farming due to the risk of soil contamination from pollutants (e.g. toxic and potentially toxic elements, persistent organic pollutants, etc.). Incineration or disposal to landfill of dewatered sludge is costly, leads to greenhouse gas emissions, and eliminates the possibility of nutrient recovery, especially phosphorus. Options to treat dry organic matter are combustion and gasification, among other technologies to produce ashes or chars and to recover the residues for nutrient recycling. Dependent on the technology applied as well as the input material, nutrient concentrations and concentration of contaminants vary... |

| Organic wastes from urban areas include organic household wastes, food processing residues and catering wastes. These so called "Urban Organic Wastes" are important potential sources for nutrient recycling back to agriculture. Main waste treatment options for these sources are composting and anaerobic digestion. Both differ in the process performance – regarding for example emissions or energy balances – and in the characteristics of the final fertilizer product. This fact sheet describes the most important aspects of compost and digestates from urban organic wastes for use in organic farming. |

| In the past meat and bone meal was a major source of nutrients for recycling back to agricultural land, either as animal feed or organic nitrogen and phosphorus fertilizer. Nowadays - since the Bovine Spongiform Encephalopathy (BSE) crisis in 1999 - it is mainly used as fertilizer. Although meat and bone meals are allowed by EU regulation in organic farming, several growers’ organisations prohibited them since the BSE crisis. Incineration or melting in a cupola furnace are alternative treatment options to their direct use eliminating any risk on BSE transmission. However, these processes lead to losses of organic matter as well as nitrogen and sulfur and affect the phosphorus availability. The fact sheet shows which actions are needed to ease the statutory... |

| Two parallel experiments were conducted at the Teaching and Research Farm, Ladoke Akintola University of Technology and Papa Aireke Farm, both at Ogbomoso, Nigeria, to assess the effect of four different compost types on the nematode population dynamics; the growth and yield of okra, sown into nematode infested soil. Each of the compost was prepared through Rapid Composting Technology with Trichoderma harzianum as decomposer, using Windrow method. The four compost types were neem based, cassava peel based, sawdust based and Tithonia based. Nematode susceptible okra variety (NHAe-84-1) was used as test plant. The compost was applied at the rate of 1ton/ha to the treated okra while the okra plants on the untreated soil served as the control. The experimental... |

| In this project, located at Winklhof, a comparison between organic and conventional farming is done. The field trial combines a crop rotation with two levels of fertilisation intensities (one is 1.0 LU ha- and the other is 1.8 LU ha-1). The fertilisation-systems are stable-manure and liquid manure, the treatments were done organically. The aim of this project is to find out which production system is better for the environment in spite of crop yield, product quality and leaching losses. The last parameter was measured in lysimeters. A high amount of yearly precipitation could account the high amount of seepage water. Consequently the leaching losses of both production systems could be compared. |

| Ökologisch erzeugte Kartoffeln, die zur Verarbeitung zu Pommes frites oder Chips genutzt werden sollen, müssen besondere Qualitätseigenschaften aufweisen. So wird beispielsweise ein mittlerer bis hoher Stärkegehalt bei gleichzeitig niedrigen Gehalten an reduzierenden Zuckern gefordert. Um den von der verarbeitenden Industrie geforderten Qualitätsansprüchen gerecht zu werden, ist neben einer ausgewogenen Düngung gerade auf leichten Böden auch eine ausreichende Wasserversorgung entscheidend, die oft nur über Beregnung sichergestellt werden kann. Unter den Fragestellungen, ob organischer Dünger (Stallmist) durch die Beregnung besser von den Verarbeitungskartoffeln ausgenutzt werden kann und inwiefern Ertragsstruktur und die Qualitätsparameter von... |
