Temperature, relative humidity and air speed were measured during 4 weeks in two compartments of a fattening pig house. Temperature was controlled by automatic regulation of the extractor fan. Average NH3 and CO2 concentrations over a 8-h period were measured 4 times in each compartment at 1-week intervals. In a compartment without pigs, ventilation rate was measured at 8 fan speeds and air speed was measured in 6 pens. Mean temperature was 24C and relative humidity 71%. despite large variations of outside temperature, 95% of the daily variations of inside temperature were <6C and 68% of the hourly variations were <0.5C. More than 90% of the daily variations of relative humidity were <20%. Thermal regulation with the fan was therefore effective. Mean NH3 concentration was higher than the usual recommendations, 26(vs 20) ppm and the CO2 concentration lower, 1688 (vs 3000) ppm. Measurements of ventilation rate showed that the air inlet area was too small for the maximum power of the fan. The ventilation rate was at most 3200 m/h for 78 pigs. Air speeds higher than 0.2 m/s were also measured 0.5 m above the floor in some of the 6 pens. These excessive values could be related to air inlet area. [less ▲]

Computer science and the systems that it helped set up are gaining ground in the realm of forest management through still fledgling or already proven achievements such as on site electronic data in put, data base management, geographic information systems, decision making aids, establishing of growth, management, simulation and optimization models, experts systems. Albait this trend, one should not forget that it is essential to collect good quality data, to set clear objectives instead of just yielding to a fad: the computer cannot substitute the forest manager.

L'azote minéral présent dans le sol et son utilisation par le froment d'hiver ont été régulièrement suivis dans trente-cinq essais installés au cours de six années. Il en ressort que la fumure azotée optimale (dose totale et fractionnement) est propre à être calculé en fonction des facteurs pédoclimatiques, du passé cultural de la parcelle et de l'état de la culture. La fumure ainsi déterminée permet d'atteindre un rendement proche de l'optimum économique tout en limitant au maximum les reliquats en azote minéral après culture. [less ▲]
