Climate has a great influence on soil moisture conditions. The engineering behaviour of soils is governed in large measure by their moisture contents. Most clay subsoils exist in an approximate state of moisture equilibrium that may be seriously disrupted by construction drainage or irrigation. Lawn watering in urban area can have results equivalent to a substantial increase in rainfall ... This practice often results in a marked increase in subsoil moisture and volume and brings about new problems for shallow foundations. 2, record 1, English, - equilibrium%20moisture%20content

Le potentiel matriciel de l'eau du sol. [...] Trois types de mesure sont couramment utilisés :-par extraction de l'eau sous pression [...]-par équilibre hygroscopique : au contact de l'air, un échantillon du sol humide se dessèche jusqu'à ce que soit atteint un certain équilibre. Le potentiel matriciel en mégapascal est alors égal à 1, 064 Tlog U(U représentant l'humidité relative de l'air et T la température absolue). Il suffit donc, après équilibre, de déterminer l'humidité de l'échantillon pour obtenir un point de la courbe reliant le potentiel à l'humidité. Cette méthode est applicable à la gamme allant d’environ-5 à-1 000 mégapascals.-par tensiométrie. 1, record 1, French, - %C3%A9quilibre%20hygroscopique

L’évapotranspiration et les flux turbulents de chaleur sensible et latente sont d’abord évalués au niveau de la station micro-météorologique de référence. Un indice de l’humidité disponible dans le sol est ensuite calculé à partir du rapport du flux de chaleur latente et du bilan énergétique de surface. Cet indice est sensé être représentatif de toute la Belgique, le principal facteur gouvernant l’évapotranspiration étant, dans les climats tempérés, le rayonnement net modulé par la présence ou l’absence de nuages. 1, record 2, French, - indice%20de%20l%27humidit%C3%A9%20disponible

The relative moisture of the soil is expressed, for each depth, by the ratio 100 Ha/He, where Ha is the absolute moisture of the soil and He, the absolute moisture for a pF value of 2.7 (moisture equivalent). pF is the logarithm, to base 10, of the capillary potential. 3, record 3, English, - relative%20moisture%20of%20the%20soil

In general, since there exists a water shortage to crop requirement and possible water resources for watering crop, it is suggested to economically control soil relative moisture within 0.55-0.82 by irrigation, that is, supplies crop water by 50-90% of its water requirement. 2, record 3, English, - relative%20moisture%20of%20the%20soil
