- Abstract:
- ... Silage is one of the typical systems to preserve biomass usually oriented from corn, sorghum, wheat, grass, and other forage and perennial crops. A critical task within the logistics operations in silage production, i.e. harvesting, transporting, and compacting, is the management of the biomass flow, in connection with the biomass storage system and the required conditions of the stored product de ...

- Abstract:
- ... Soil steaming is a preventive non-chemical weed control method. We designed and studied a new prototype band-steaming machine. Tests were conducted during the growing cycle of organically cultivated carrot in real-field conditions, in order to study the effect of different steam doses on crops and a natural weed seedbank, throughout the whole growth cycle. The prototype has a 3265 MJ h−1 steam gen ...

- Abstract:
- ... The leaf area index (LAI) is a key parameter describing the state and progress of crop canopies. Determination of LAI via proximal sensing supports decision-making processes in precision agriculture and improves biophysical modelling. Here we introduce the Canopy-Meter – a mobile sensor designed for determining LAI while driving over the field. The operating principle is based on the transmittance ...

- Abstract:
- ... The effects of cover optical properties on screenhouse radiative environment and sweet pepper productivity were investigated in a Mediterranean climate (Eastern Greece) under three covering materials (i) a pearl insect-proof screen (IP-78), (ii) a white insect proof screen (IP-59) and (iii) a green shade-screen (GS-62) with values of the transmittance to photosynthetically active radiation (τPAR) ...

- Abstract:
- ... The sunflower harvest season presents challenges for many farmers when an abundance of airborne dust is carried by surrounding winds and allowed to relocate on equipment surfaces. Combine fires are a serious problem resulting from the ignition of biomass dust that settle and accumulate on the combine harvester. Farmers' anecdotal evidence indicates that harvesting sunflowers can produce more airbo ...

- Abstract:
- ... The proposed work aims to assess the energy crop suitability of Puglia Region (Southern Italy), the techno-economic feasibility of small scale CHP plants fired by energy crops, and the environmental performances of the proposed CHP plants. In the first part of the work, a GIS model is defined and applied to evaluate the land suitability for energy crops in the Puglia region. In the second part, a ...

- Abstract:
- ... The calculated values of solar energy potential permit the evaluation of the maximum possible performance of energy capture systems. This is very important in engineering projects designed to make use of solar energy in its various forms, including capture by the biomass, photoelectricity for small potentials, direct capture by collectors, irrigation of crops, agricultural potential production, ag ...
