Aspecte privind irigarea cu apă din surse locale a solului cenușiu molic [Articol]
(USARB, 2017) Filipciuc, Vladimir; Boaghe, Lilia
The use of water from local sources (inland rivers, lakes, ponds) at irrigation raises difficult issues because of its improper chemical composition and quality indicators. The irrigation of molic gray soil with water from pond with high content of magnesium leads to neutralization of actual and hydrolytic reaction, modification of ratio of cations in the soil solution, contribute to the substitution of exchangeable Ca 2+ and accumulation of Mg 2+ in the adsorption complex. These processes favor adsorption of Na+, thereby intensifying secondary sodiumisation of soil. There were registered negative changes in the composition of humus, which refers to the decrease of the ratio between humic and fulvic acids, but also to a significant decrease of content of the fraction of humic acids associated with calcium. Use of ‖magnesium‖ water modifies the content and composition of soluble salts.
Particularităţile ecologice ale microtinelor – dăunători ai culturilor agricole [Articol]
(USARB, 2017) Sâtnic, Veaceslav
Climate conditions that favored vegetation growth made up an important prerequisite for the increase of M. arvalis population density from 2-4 colonies per hectare in April on the lucerne fields in the Center region up to 80 colonies per hectare in September and even 200 – in October. The highest levels in agrocenoses have been registered in July and October – 23% and 29,6% respectively. The index of anthropic adaptation (Ii) of the studied species of small mammals has also been determined. The highest values of this parameter have been recorded in M. arvalis (14.3) and M. rossiaemeridionalis (12,5). This is explained by the adaptive peculiarities, their individuals being primary consumers of vegetable food (lucerne, clover, etc.). The equation of multiple linear regression was developed and it reflects the correlation between the number of M. arvalis individuals expressed in colonies per hectare and the monthly Martonne aridity index D=-15.67 + 2,88*Ia, that allows the forecast of the number of microtine species.

(USARB, 2017) Grigoraş, Nicolae; Florenţă, Gheorghe; Agapi, Ion
Knowing the importance and value of oak species from the national forest fund, were analyzed the requirements of native oak species (Quercus robur, Q. petraea, Q. pubescens) towards various physico-geographic parameters, with the purpose of identifying the limits and the optimal niches for their development. It was identified that the most demanding oak species to substrate conditions and climatic parameter values are Quercus petraea and Quercus robur, toward Quercus pubescens which is more tolerant to high annual average temperatures, and little rainfall. This explains the future trends of Quercus pubescens which in the context of climate aridization, can easily adapt to the drought and occupy new sectors, in the detriment of the Quercus robur and Quercus petraea species.
