During one intensive week in October 2005, the authors were gathered to discuss the impact that globalisation has on the Organic Food Systems and the opportunities that globalisation opens up for developing these systems. The meeting took place as a Ph.D. course under the auspices of the Research School of Organic Farming and Food Systems (SOAR; www.soar.dk). All participants research within Organic Agriculture and Food Production in one way or another
Analysis of spatial soil moisture variation on a cracking clay soil for optimizing sprinkler irrigation management
The objective of this research was to assess the impact of soil cracks on soil moisture distribution under various sprinkler irrigation applications and to identify the optimal irrigation strategy. The assessment was made for six irrigation events using: hand shift-set sprinkler system, lateral move system with fixed sprayer heads and lateral move system with rotating sprinklers. The experiments were conducted on two adjacent fields. Each field was divided into 2x2 m grids that covered 62 sampling locations. The soil physical and hydrological properties, field slope, soil texture and infiltration rate were defined. Since the soil was cracking clay, further analysis was conducted on the crack dynamics, size and distribution using image analysis techniques. Improving the irrigation system application uniformity did not always result in higher uniformity of the surface soil moisture content (0-25 cm). The event that best enhanced soil moisture distribution was observed when the field received 32 mm water application. The soil was at a relatively high initial soil moisture content of 25%. At this soil moisture content, the extent of soil cracking on the drainage water was limited
Operational precise irrigation for cotton cultivation through the coupling of meteorological and crop growth models.
In this paper, we tested the operational capacity of an interoperable model coupling system for the irrigation scheduling (IMCIS) at an experimental cotton (Gossypium hirsutum L.) field in Northern Greece. IMCIS comprises a meteorological model (TAPM), downscaled at field level, and a water-driven cultivation tool (AquaCrop), to optimize irrigation and enhance crop growth and yield. Both models were evaluated through on-site observations of meteorological variables, soil moisture levels and canopy cover progress. Based on irrigation management (deficit, precise and farmer’s practice) and method (drip and sprinkler), the field was divided into six sub-plots. Prognostic meteorological model results exhibited satisfactory agreement in most parameters affecting ETo, simulating adequately the soil water balance. Precipitation events were fairly predicted, although rainfall depths needed further adjustment. Soil water content levels computed by the crop growth model followed the trend of soil humidity measurements, while the canopy cover patterns and the seed cotton yield were well predicted, especially at the drip irrigated plots. Overall, the system exhibited robustness and good predicting ability for crop water needs, based on local evapotranspiration forecasts and crop phenological stages. The comparison of yield and irrigation levels at all sub-plots revealed that drip irrigation under IMCIS guidance could achieve the same yield levels as traditional farmer’s practice, utilizing approximately 32% less water, thus raising water productivity up to 0.96 kg/m3.N/
