The paper aimed to present the quality of some soils from the West Region from Romania. The soil types who were studied occupied a surface of 4.013 ha in Arad Department. The main soil types who was founded in this area is Chernozems on 75.54% from the surface, Haplic Phaeozems on 2.43% from the studied surface, Pelosols on 7.66% from the surface, Vertisols on 13.15% from the surface, Gleysols on 0.36% from the surface and Solonetz on 0.86% from the studied surface. This paper presents a synthesis of the limiting ...

According to the European Environment Agency, soil is involved in providing more than 90% of the total production related to human nutrition, animal feed, textile fibers and fuels, while also providing the raw material for all kinds of other related activities, such as horticulture and construction. In order to monitor soil quality, it is necessary: common analyzes for all types of soils (with soil samples in disturbed and undisturbed structure) and typical soil analyzes (for soils: unsaturated with basic cations,...

This research was conducted for six years, in experimental fields located in B-rzava Plain, West part of Romania. The purpose of this research was to observe if a mixture of manure and calcium carbonate can improve some fertility indicators of soil. The monitored soil fertility indicators were: pH, humus content and nitrogen index. The mixture applied on the experimental field contain 20 t/ha cow manure and 4 t/ha calcium carbonate, being distributed in the first experimental year and in the fourth experimental ye...

Potassium (K) is a crucial mineral nutrient that plays a significant role in various physiological and metabolic processes in plants. Disruptions in potassium supply can severely impair vegetative development, making efficient potassium fertilization strategies essential for maintaining plant health and productivity. As the most abundant inorganic cation in plant cells, potassium is vital for proper physiological functioning, primarily existing as a free ion (K?). It is indispensable for several physiological func...

The impact of abandoned mines on the water environment is a significant concern due to the long-lasting ecological and health effects associated with mining activities. Numerous scientific studies highlight that abandoned mines pose substantial threats to local water quality through the release of toxic substances and heavy metals into adjacent ecosystems. The zones of the 2 mines have been subject to various environmental and hydrological assessments, particularly concerning the effects of mining activities on wa...

Soil organic matter (SOM) plays a crucial role in maintaining soil fertility and ecosystem stability by influencing nutrient cycling and water retention capacity. Climate change, manifested through rising temperatures, extreme precipitation variability, and increased frequency of extreme weather events, directly affects the dynamics of SOM decomposition and accumulation. This paper examines the mechanisms by which these climatic changes impact SOM stability, emphasizing their effects on agricultural and natural so...

Urban soil contamination with heavy metals is a growing environmental concern due to its adverse effects on human health, ecosystem stability, and soil productivity. The primary sources of this pollution include industrial activities, vehicular emissions, atmospheric deposition, mining operations, and improper waste disposal. As heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), and chromium (Cr) accumulate in the soil, their persistence and low mobility make them difficult to degrade or rem...

This study investigates the effects of foliar fertilization (FF) on the yield and quality of corn grains, utilizing Principal Component Analysis (PCA) to optimize foliar treatment applications. The PCA approach enabled the identification of the most effective FF formulation for enhancing grain production and quality. The experiments were conducted in 2022 and 2023 at the university's experimental field, evaluating seven treatment variants, each with distinct chemical compositions labelled from V1 to V7, along with...

The application of nitrogen fertilizers in the form of urea tends to increase acidity, especially on low pH soils, and as a result can lead to increased aluminum toxicity, which can adversely affect not only soil properties such as microbial activity, but also productivity. Application of different types of urea with inhibitors to reduce nitrogen losses would result in a different carbon response to fertilizers applications for the same soil type because of differences in soil micro-environment, including microbia...

The use of pig slurry as fertilizer has a clear impact on farm-level energy input requirements, being a correct and natural way of its decomposition and also contributing to the reducing of the amount of chemical fertilizers used, which, in addition to the high cost, may leads to the pollution of the areas where they are applied. Swine sludge could provide between 38 and 61% of the nitrogen, phosphorus and potassium in chemical fertilizer. The purpose of the work is to determine the changes that the application of...

Achieving profitable crop production milestones hinges on the establishment of a robust soil fertility program. Such programs demand foresight and meticulous planning. To ensure the profitability and efficiency of wheat cultivation, it is imperative to provide the right amount of essential plant nutrients precisely when and where the crop requires them. The application rates of fertilizers hold little significance if these vital nutrients are not distributed at the appropriate locations and times. Wheat, in partic...

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...

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...
