The paper presents the effect of zeolitic volcanic tuff on soil fertility as a consequence of treating soil with zeolitic tuff supplies (clinoptilolite rich tuff). This high silicon tuff type and the essential features of the clinoptilolite has generated in time changes in soil properties like soil reaction, an effective pH buffering, increase of water absorption and cation exchange properties. The effect of using three different doses of zeolitic volcanic tuff, with and without ammonium nitrate addition as fertil...

Waste and by-products from the food industry put pressure on the environment. FAO defined food losses as losses along the food chain between producer and market, while safe and nutritious food is thrown away as waste. About a third of the food produced is wasted. A significant amount of food is disposed of as waste, especially in developed countries, and this also means the disposal of resources used to produce food. Food waste is not only an economic problem, but also an environmental and moral problem. Food dive...

A good soil fertility program requires vision and planning. Achieving cost-effective and efficient wheat production involves providing sufficient amounts of plant nutrients when and where the crop needs them. Wheat is a particularly demanding crop for fertilization, which reacts positively to the application of fertilizers. Cereal consumes moderate amounts of nutrients due to the fact that its roots explore a smaller volume of soil. The influence of foliar fertilizers for different crops is diverse and depends on ...

Nowadays, wheat is the most important food source worldwide and rapeseed has become one of the alternative sources of energy, that is, biofuel. In the current global economic context, the practice of intensive farming, by applying large amounts of fertilizers is no longer sustained, mostly because of the negative environmental impact and also because of the high prices of fertilizers. It is imperatively necessary to practice an efficient management of nitrogen fertilizer, in order to avoid both environmental and e...
