| In a field trial established in 1994 by the foundation „Stiftung Ökologie und Landbau“, different primary tillage systems are being tested on their influence on root and shootgrowth of cereals. The tillage implements are : mouldboard plough, two layer plough and layer cultivator. Investigations oriented on soil physical parameters ( e.g. aggregate stability ), root parameters ( e.g. root-length-density ), shoot growth ( e.g. dry matter, yields) and laboratory analysis ( e.g., P, K Ct/Nt contents ). These parameters were also tested for the weeds, that can strongly compete with the crops, especially in reduced tillage systems. The results of the investigations combined with knowledge obtained from previous work and literature are being interpreted in order... |

| SOILHEALTH.CAPSELLA.EU platform supports farmers across Europe in maintaining healthy agricultural soils. The spade-test application on the platform allows self-assessment of soil health using a widely used, qualitative method for performing the observation of soil conditions (spade test). It gives the farmer information on soil fertility and on mechanical operations effects on its structure. Farmers, by using the application for recording their observations, are able to share their findings, learn from each other and seek further advice to the community by working with open software, open data and open hardware. The spade test application, available for PC, tablet and smartphone, guides the user through an easy touch-enabled interface to define the soil... |

| In two organically cultivated field trials, located in Germany and Greece, effects of reduced primary tillage systems on root and shoot growth of cereals were investigated. The field trial in Rommersheim near Mainz, Germany, was established in 1994 by the foundation „Stiftung Ökologie und Landbau“. The Agricultural University of Athens established in 1995 a similar experiment in a field trial carried out by The Laboratory of Crop Science, located in Athens, Greece. |

| In two organically cultivated field trials, located in Germany and Greece, effects of reduced primary tillage systems on root and shoot growth of cereals were investigated. The field trial in Rommersheim near Mainz, Germany, was established in 1994. A similar experiment was established in 1995 located in Athens, Greece. Mouldboard plough, two-layer plough and layer cultivator were used in Germany. Mouldboard plough, rotary hoe and zero tillage were applied in Greece. The field experiment in Germany was performed on a clay loam soil with a 5-year crop rotation (green fallow, winter wheat/catch crop, peas, winter rye/catch crop, spring barley) in a split-plot design. The investigated crop was spring barley and winter rye. Tillage systems were implemented... |

| AEGILOPS Network Ecology and Biodiversity in Agriculture was established in 2004. Our purpose is to conserve heritage varieties and traditional agricultural knowledge and to restore landrace varieties into contemporary agricultural practice in ways that benefit the traditional farmers. The goals of AEGILOPS are: a. to develop plant varieties adapted to local organic production which utilize the benefits of locally adapted genetic resources for ecological agriculture, and b. to strengthen the role of the farmers in the conservation of genetic resources as well as to protect their rights in taking part in the management and benefits of agrobiodiversity. |

| Optimierte bodenphysikalische Eigenschaften sind Grundlage der Entwicklung vitaler Getreidebestände und hoher Kornerträge. Wurzelwachstum und Wurzelaktivität stehen in engem Zusammenhang mit Bodendichte, Porenverteilung, Eindringwiderstand und dem gewogenen mittleren Aggregatdurchmesser. Konventionelle Grundbodenbearbeitung mit dem Wendepflug führt häufig zu ungünstigerem Bodengefüge, im Zusammenhang mit hohen Auflasten, zu Pflugsohlen. Ziel des Projektes war es, den Einfluß verschiedener Bodenbearbeitungssysteme auf bodenphysikalische Eigenschaften und das Wurzelwachstum von Wintergerste unter den klimatischen Bedingungen des Mittelmeerraums zu untersuchen. |
