Improvements in crop management for a more sustainable agriculture are fundamental to reduce environmental impacts of cropland and to mitigate effects on global climate change. In this study three fertilization types – ammonium nitrate (control); mineral fertilizer added with a nitrification inhibitor (3,4-dimethylpyrazole phosphate (DMPP)), and an organo-mineral fertilizer (OM) – were tested on a tomato crop in order to evaluate effects both on crop production and soil N<sub>2</sub>O emissions. Plants grown under OM fertilization had a greater relative growth rate compared to mineral fertilization, due to a higher net assimilation rate, which was related to a greater light interception rather than to a higher photosynthetic efficiency. OM fertilization determined the highest fruit production and lower soil N<sub>2</sub>O fluxes compared to NH<sub>4</sub>NO<sub>3</sub>, although the lowest soil N<sub>2</sub>O fluxes were found in response to mineral fertilizer added with a nitrification inhibitor. It can be concluded that organo-mineral fertilizer is a better nutrient source compared to mineral fertilizers able to improve crop yield and to mitigate soil N<sub>2</sub>O emission.

<p>The present study investigates the potential of olive mill wastewater, treated by microfiltration and XAD4 macroporous resin, to be used as liquid fertilizer in maize production through a 2-year field experiment. The treated olive mill wastewater (T-OMWW) was applied at two rates of 25 t and 50 t per ha per year, supplemented with mineral fertilization. There was also a treatment involving the application of only T-OMWW at the rate of 50 t per ha per year, and an only mineral fertilizer treatment. Mineral fertilizers and T-OMWW were applied progressively through a drip irrigation system.</p> Maize grain and soil analysis showed that T-OMWW was capable to meet crop requirements in N, P and K, and increase soil N, P and K availability. There was a tendency for increasing soil Na and electrical conductivity (EC) using the higher rate of T-OMWW. Therefore, for sustainable agriculture, it may be safer to apply the T-OMWW at the lower rate of 25 t per ha<sup> </sup>per year, or use the higher rate of 50 t per ha<sup> </sup>every other year.

The conversion of high-input agriculture to an agro-ecological approach bring harmony to the environment reducing degraded Agroecosystems. The objective of this study was to evaluate the effect of different nutritional management on yield and internal and external quality of tomato fruits as an alternative to the reduction of mineral fertilizers. The research was carried out at the National Institute of Agricultural Sciences (INCA) in Cuba, from September 15 to November 30, 2016. A randomized block design with four replications was used to study four treatments: Absolute control (without mineral fertilizer and bioproducts), Partial ecological nutrition (50 % of mineral fertilizer + bioproducts: mycorrhiza and biostimulant), Organic nutrition (organic fertilizer + bioproducts: mycorrhiza and biostimulant), and Conventional nutrition (NPK mineral fertilizer only). Evaluations regarding agricultural yield and its components, bromatological quality of fruits (Brix, acidity, vitamin C content, and nitrates) and postharvest indices (fruit firmness and diameter of endocarp and mesocarp) were performed. Agricultural yield (25.31 t/ha) and the internal quality of fruits (5.23 °Brix; 11.75 SST; 73.29 nitrates; 18.54 vitamin C, and 4.45 dry matter) applying the treatment where 50% of mineral fertilization was dispensed and complemented by bioproducts did not show significant differences with NPK treatment. Regarding the organic variant, the result in agricultural yield was lower (19.42 t/ha), in comparison with control and the ecological variant. Therefore, it is suggested further evaluation of the effect of the reduction of mineral fertilization on tomato crop and its combination with bioproducts.

Sewage sludge (SS) or biosolid has been studied as source of nutrient for several different plant species. It also contributes to soil fertility recycling organic matter and plant nutrients. This followup work examines a three-year (2001–2004) field experiment designed to evaluate the response of banana plants (Cavendish subgroup) to the application of biosolid as source of nitrogen. The treatments consisted of control (mineral PK, no N), three rates of sludge, and two rates of mineral NPK fertilizer. Plant and soil N concentration, fruit yield, plant height, stem diameter, and foliar endurance index were measured. Fruit yield with mineral fertilization or sludge applications did not differ statistically(P>0.05). Application of biosolid resulted in statistically significant higher agronomic efficiency(P<0.05)in comparison to mineral fertilizers. The concentration of soil mineral nitrogen increased using mineral fertilizer or sludge until 0.80 m after three years of application. The effect of the source of N was smaller than the effect of the rate. Biosolid can be used as source of N for banana growers.

Large amounts of fertilizers are being used in agriculture to sustain growing demands for food, especially in vegetable production systems. Soluble fertilizers can generally ensure high crop yields, but excessive leaching of nutrients, mainly as nitrate, can be a major cause of water pollution. Controlled-release fertilizers improve the nutrient use efficiency and lower the environmental hazard, usually without affecting the production. In this study, an innovative controlled-release coated urea fertilizer was compared to conventional nitrogen (N) fertilizers and a soluble ammonium-based fertilizer containing a nitrification inhibitor, in a round table tomato cultivation. Both the water and N balance were evaluated for each treatment, along with the yield and quality of the production. The experiment was repeated in three different seasons (spring, autumn and summer-autumn) in a glasshouse to prevent the effect of uncontrolled rainfall. The results indicated that N leaching decreased by increasing the percentage of coated urea. The application of at least 50% total N as coated urea strongly reduced N leaching and improved N agronomic efficiency in comparison with traditional fertilizers, ensuring at the same time a similar fruit production. Due to reduced leaching, the total N amount commonly applied by growers could be lowered by 25% without detrimental effects on commercial production.

The feasibility of reducing non-renewable natural resources use in agriculture, associated with the need for ecologically-appropriate of organic waste disposal has become an important element in planning more sustainable agricultural systems. Consequently, the aim of the current study was to evaluate the response of the common bean, growing in an Eutrophic Latosol in the city of Buri-SP, to the application of organic and mineral fertilizers. An experiment was carried out in the 2015 agricultural year, using a randomized block design with 4 replicates and 5 treatments, these being: 1 - mineral fertilizer; 2 - organomineral fertilizer; 3 - sheep manure compost; 4 - chicken bedding compost, and control (soil without fertilizer application). The tested variables were: pod length (cm); per plant pod number; per pod seed number; mass of 100 grains (g); and grain yield (kg ha-1). Organomineral fertilizer provided the most significant increase in pod length, per plant pod number, and yield compared to the other treatments, except for sheep manure compost, where productivity did not differ. In addition, with the exception of mass per 100 seeds, there was no difference between treatments using organic fertilization and mineral fertilizer. Under the current study´s experimental conditions, organomineral fertilizer and sheep manure compost produced the highest productivity for common beans. Thus, mineral fertilization can be replaced by organic or organomineral alternatives, so helping to produce more sustainable production management and help reduce environmental impacts.

The use of mineral fertilizer in horticultural crops is a very important issue due to its effects on crop yield and its environmental impact. For the period 2011-2012, the total mineral fertilizer consumption in EU-27 reached 10.4 million tons of nitrogen (N), 1.0 million tons of phosphorus (K) and 2.2 million tons of potassium (K). Though many recent studies have examined horticultural crops, few have focused on mineral fertilizers in order to make an environmental assessment of a tomato crop. Therefore, the aim of this research was to study the agronomical (i.e. yield) and the environmental performance of a horticultural tomato crop fertilized with four different doses of mineral fertilizer (N0, N1, N2 and N3), using Life Cycle Assessment methodology. Data and conditions for the crop were taken from a real field trial with an experimental design carried out in North-east Catalonia, Spain. Following the guidelines of the ISO 14044, the study considered all stages of the life cycle of a horticultural tomato crop (i.e. mineral fertilizer production, transport and cultivation phase). Six impact categories were included in the study: climate change, photochemical oxidation formation, land acidification, freshwater and marine eutrophication and fossil depletion. Overall, the results showed that the best result was for the N1 treatment, with a yield of 61 ton ha-1 and 55 ton ha-1 for total and commercial yield, respectively. N1 showed the best environmental performance in all categories assessed.

The Impact

The aim of the article is to estimate the impact of reducing the consumption of mineral fertilizers resulting from the New Green Deal assumptions on the yields of major crops in the 2030 perspective. The material for analysis was statistical data from the CSO and FAO. The collected data was processed dynamically by using trend analyzes and Pearson linear correlation. Maintaining the current trend of increasing the dose of NPK mineral fertilization will allow the use of crop production potential in Poland. On the other hand, the introduction of the NGD assumptions may result in a stagnation of crop yield at the current level. However, in relation to the scenario assuming the continuation of the current upward trend, these yields will be much lower. Reducing mineral fertilization introduced by means of an administrative decision without taking the principles of rational management of fertilizer components into consideration may have negative environmental consequences.

The dependence of mineral fertilizers, increasingly, has brought concern facing the increased demand and because it is a non-renewable mineral resource. The organic fertilization, exclusively, it is impractical in large scale, however, the combination of organic and mineral sources have already proved to be feasible, both from the point of view of nutrition of plants as well as in the aspect of recycling of urban and industrial waste by agriculture. This research had as objective to determine the efficiency of aorganomineral fertilizer formulated on the basis of sewage sludge in substitution of mineral fertilizer in the cultivation of sugar cane in environments with different levels of soil fertility. An experiment was conducted in greater soil fertility, in the Institute Federal Goiano– Campus, Morrinhos-GO, Brazil. The other, less soil fertility, was implanted in the ethanol industry Tijuco Valley, located in Rio do Peixe, district of Prata-MG, Brazil. The experimental design was randomized blocks in a factorial 5 x 2 +1 being five doses, with and without a biostimulant plus an additional with mineral fertilization, in four replications. The doses were in function of fertilization recommendation of planting and coverage for each environment, consisting of: 100 % of the mineral source and percentage 0; 60; 80; 100 and 120 % of organomineral fertilizer. We evaluated the productivity, tillering, diameter and height of stem in Prata-MG the different percentages of the fertilization of planting favored and increased productivity, height and stem diameter of sugar cane; the use of biostimulants not contributed to increase crop yield. In Morrinhos-GO, the different percentage of planting fertilization did not increase the productivity, tillering, height and diameter of the sugarcane stem; the use of biostimulants increases the productivity yield of sugarcane. Organomineral fertilizer based on biosolids is similar to fertilization with mineral fertilizer in environments.

The study evaluated the agronomic performance of green maize grown on residual organomineral fertilization used in the industrial tomato crop. The randomized block design was used, with three replications and eight treatments as follows: control (without fertilizer application); mineral fertilizer; cattle manure; organomineral with cattle manure + MAP (monoammonium phosphate); chicken manure; organomineral with chicken manure + MAP; broiler litter; and organomineral with broiler litter + MAP. All of those treatments were applied to the tomato crop that preceded the green maize crop. After the tomato harvest, maize was sown in the same tomato growing row. Growth variables of green maize plants and ears were evaluated. The green maize grown in areas with residues of chicken and cattle manure, used as fertilizers in the tomato crop preceding the maize crop, resulted in a number of commercial ears similar to when mineral fertilizer was used. The same similar results were obtained for ear quality and yield. The use of organic fertilizers in the industrial tomato crop presented high viability, which made possible to replace the use of mineral fertilizers in the subsequent green maize crop.

Fertilizer System

One of the main factors of intensification in crop production is the effective using of mineral fertilizers. There must be a clear and correct approach to the development of the crop fertilizer system, in the context of the current reduction of the soil’s natural fertility and high environmental burden. A scientifically sound fertilization system must ensure not only high crop yields with optimum product quality indicators, but also the preservation or different increase of soil fertility while maintaining environmental safety. The effectiveness of mineral fertilizers depends on both the ratio of nutrients and their forms. With the same amount of active substance, different forms of fertilizers provide different results, due to the physiological characteristics of fertilizers and plants. The rational application of fertilizers is only possible when understanding the deep connection between soil agrochemistry and plant physiology. The highest yield of sunflower hybrids was obtained in the case of fertilizer application at a dose of N60P90. The application of mineral fertilizers with different doses increases the yield of sunflower hybrids by 0.16-0.43 t / ha. However, the level of mineral fertilizer efficiency varies and depends on other factors. Therefore, the question of the effectiveness of the application of mineral fertilizers during the cultivation of sunflower in the conditions of the zone of insufficient moistening of the Steppe of Ukraine needs more systematic study. Key words: sunflower, mineral fertilizers, mineral nutrition, cultivation technology, yield, plant density, biological yield.
