In the conditions of the Banat's Plain (Romania), chicory can be an important fodder crop well adapted to the climate conditions in the area. Research results show that this species is positively influenced by the use of chemical or organic fertilisers. Applying nitrogen fertilisers on a yearly basis at rates of N50-100 lead, in the second vegetation year, to productions higher with 22-34% than in the control variant (no fertilisation). The remnant effect of animal manure was obvious in the second year of application too, when we obtained, at a rate of 40 t/ha, an increase of 26% compared to the control variant.

The power plant ash is an inorganic residue with a variable chemical buildup according to the type of charcoal used and quality. Depositing, stabilizing and eventually reintegrating the ash in the natural circuit raises a series of problems due to its disastrous effect on biodiversity. Even with these problems, at a moderate micro and macro mineral content, power plant ash could present interesting agro technical and ecological alternatives. For this reason, the controlled integration of ash could put a stop to pollution with ash by reintegrating the material in the agricultural ecosystems. For this purpose, in the field of research of Ecological and Forage Crops from Faculty of Animal Science and Biotechnologies Timisoara, research was conducted over the influence of the reintegration of 40 t of ash per ha, produced by C.E.T. Timisoara, on the biomass production of oatmeal (Avena sativa L), fertilized by levels of 25 and 50 t per ha of manure. After harvesting, the analysis of the total biomass quantity, both above and underground, revealed similar results in all trials. In conditions that include heavy metal concentrations beneath normal geological values, conclude that the application of 40t per ha may be an agro technical solution for the integration of power plant ash in the agricultural ecosystem.

The compost tested in this study resulted from the anaerobic fermentation process of sewage sludge with cereal straw. Processing and post-treatment were made by Biotechnological Research Centre within INCD ECOIND from Bucharest. Experimental program included testing the effect of fertilizer in quantities of 25 t, 50 t and 100 t compost / ha on the production of soya beans. It was also investigated the influence of the combination of fertilization with compost and inorganic fertilization with levels of 200 kg, respectively, 400 kg NPK / ha. Was analyzed the following productivity indicators: plant density, number of floors of pods, number and weight of pods and total beans production, in full ripening stage. In the case of fertilization only with composted sludge, production of peas and beans was higher in variants with 50 t / ha and 100 t / ha (2095 kg and 1990 kg grain / ha). Therefore, doubling the amount of compost does not provide corresponding increase yields of soybeans. Combining organic and inorganic fertilization determine a proportional production increase only for the total biomass production. The tested compost is a good organic fertilizer and the amount that provides the greatest soybeans production is 50 t / ha. [ABSTRACT FROM AUTHOR]

Permanent grasslands represent, all over the world, an asset that contributes to maintaining ecological balance in all other natural ecosystem, a never-ending reservoir of vegetal biomass that supplies most of the necessary food for animals and that can also be an important source of "green energy". In Romania, only 56% of the grassland area (i.e. 2,200,000 ha) would be enough to cover the necessary fibrous fodder for the cattle, while the rest of 44% (i.e. 1,700,000 ha) could be used to produce energy.
