In order to improve the germination via physical method, the physical properties of triploid watermelon seed were measured. Watermelon seeds of three varieties, Heiniu, Mihong and Huapi, at the moisture content of 7.02, 6.55 & 6.75 % (w.b.), were selected to study the physical properties using standard methods, respectively. Experimental results obtained the physical properties' parameters, length,...
Filter media is the most pivotal element of artificial soil filtration system and directly impact the reduction of contaminants in runoff. Four typical filtration materials including sand soil, boiler slag, furnace cinder and ceramsite are selected and studied in laboratory scale in Beijing. The experiment is carried by two stages. One is selection of filtration media. Firstly, different materials'...
A complex of techniques and methodics to investigate heat, moisture and water soluble peat soils compounds transfer characteristics has been described.Water-physical characteristics and characteristics of peat soils heat and mass transfer of Belarus and Poland have been provided. The characteristics obtained may be used to prognosticate and optimize temperature and moisture and peat soils saline regimes.
Możliwość monitoringu parametrów wody glebowej jest warunkiem koniecznym kontrolowania oraz matematycznego modelowania procesów zachodzących w kontinuum gleba-roślina-atmosfera, a więc i prognozowania ich następstw. Biorąc pod uwagę, żc integrowalne we współczesnych cyfrowych systemach akwizycji danych są wyłącznie czujniki "czytane" elektrycznie, należy dysponować elektrycznymi czujnikami...
