The major disadvantage of setting up a willow coppice is the low survival rate, which reduces economic efficiency and crop sustainability. The aim of this research was to test, under controlled conditions, the impact of water, gibberellic acid A3 (0.05%), and humic acid (0.2%) on the growth and development of two willow clones. Under humic acid tre...

Conservation tillage is often discussed as an effective tool to improve the soil quality in agriculture. Four sites across Europe (in Germany, Romania, Spain, and Sweden) were investigated as case studies for country-specific reductions in tillage intensity. Conventional tillage (CT) by mouldboard ploughing was compared with shallow and deep non-in...

Phytobiont enhanced nutrient uptake through arbuscular mycorrhiza comes at a cost in form of carbon fixed through photosynthesis. Geophytes operate under resource efficiency constraint due to their particular life-cycle and have to balance it very well. This translates in highly controlled investment towards mycobiont, that could explain the wide r...

Evaluation of biological assembly of a terrestrial ecosystem is generally observed from an aboveground quantitative perspective, without taking into account the diversity and extent of microbial functional processes. The use of resources is directly proportional to the microbial community structure and function, which are not reflected in current t...

Soil fauna activity in agricultural soil is a key factor to maintain soil fertility and to assure soil ecosystem services. It is now accepted that agricultural practices like tillage and pesticide use can harm soil organisms including earthworms and springtails. Other practices like the use of green manure or animal manure have been considered as b...

In the last two decades, both on International and European level a series of treaties and laws have been devised in order to save local varieties of crop plants. The most important methods of traditional seed conservation are on farm and ex situ (Maxim et al., 2010; Kontoleonet al., 2009). The identification of local Romanian varieties of bean, th...
