AB  - Cereal grains have represented the principal component of the human diet for thousands of years. Modern cereal production can not be imagined without the use of mineral fertilizers, particularly in terms of better utilization of biological potential of the yield of growing plants. The aim of this study was to evaluate the energetic efficiency of wheat and barley production, with special reference to the share of the use of mineral fertilizers in total energy consumption. Input data and yield of wheat and barley fields were collected in the experimental trials in Serbia. Results showed that total energy inputs of wheat and barley fields were 22178.04and15921.16 MJ·ha-1, respectively. Total energy outputs for wheat and barley fields were 80037.83 and 104496.08 MJ·ha-1,respectively. The results obtained indicate that mineral fertilizers claim a share of the total energy consumption in cereal production ranging from 49.19% in barley to 52.01% in wheat. Specific energy input, energy output–input ratio (energy use efficiency), energy productivity and net energy gain were 5.13 MJ·kg-1, 3.61,0.19 kg·MJ-1and57859.79MJ·ha-1in wheat system and 2.75 MJ·kg-1, 6.56, 0.36 kg·MJ-1and88574.92 MJ·ha-1in barley system, respectively. According to the results, it seems that barley production is more efficient from different aspects of energy consumption compared to wheat in the studied region. In general, production in barley fields was more sustainable than wheat production because, in view of ecological indices such as amount of energy use and renewable energy consumption, it was more environment-friendly production.

AB  - Increased demand for food production, influenced by the constant growth of population, resulted in the agricultural production systems that are more energy and economy intensive. The aim of this study was to evaluate the energetic and economic efficiency of sugar beet and wheat production. Attention was given to the fertilizer usage and its share in energy consumption since it can amount to 50%. Data show that energy input in wheat production was 5.84 MJ.kg(-1) and in sugar beet it was 0.93 MJ.kg(-1). The highest share of energy input both in wheat and sugar beet was observed for fertilizers, 52.45% and 46.70%, respectively. Economic analysis has shown that wheat production is a low profitable production with a net return of only 20.69 USD.ha(-1), in comparison with sugar beet production with a net return of 513.53 USD.ha(-1). Costs related to the fertilizer use prevailed in total variable and total production costs. Economic analysis has also shown that the benefit-to-cost ratio was higher in sugar beet production (1.33) compared to wheat production (1.03). Furthermore, it was determined that these economic indicators were less sensitive in sugar beet production than in wheat production regarding the variation of fertilizer.

AB  - The efficiency of primary agricultural production is under constant analysis relative to energy, economy and ecology. Notwithstanding technological innovations in agricultural production, engineers and researchers are still seeking to create a production system that would render the primary agricultural production more energy efficient and ecologically sustainable. The purpose of this paper is to examine the energy consumption and efficiency of crop production with an emphasis on the importance of mineral fertilizers and their influence on the overall energy consumption. The results obtained indicate that mineral fertilizers claim a share of the total energy consumption in crop production ranging from 40.53 % in sunflowers to 55.19 % in maize. A statistically significant correlation was found between the energy inputs for fertilizers and crop yields. The regression analysis performed showed a positive correlation between the energy inputs for fertilizers and yields in all the crops considered, with the exception of wheat.
AB  - Efikasnost primarne poljoprivredne proizvodnje je predmet konstantnih analiza, kako energetskih tako i ekonomskih i ekoloških.

U radu je prikazan bilans potrošnje energije u proizvodnji ratarskih kultura i skrenuta je pažnja na mineralna đubriva. Potrošnja energije je praćena u proizvodnji pšenice, kukuruza, semenskog suncokreta, šećerne repe i soje, tokom tri proizvodne sezone. Data je analiza potrošnje energije kroz sve postupke manipulacije mineralnim đubrivima do i od imanja pa do same aplikacije na parceli. Analizirana je zavisnost ukupnih energetskih inputa i prinosa i korelacija utroška mineralnog đubriva i outputa. Rezultati istraživanja pokazuju da mineralna đubriva, u energeskom bilansu ratarske proizvodnje, učestvuju sa 40,52% (semenski suncokret) pa do 55,19% (kukuruz). Najintenzivniji utrošak energije po jedinici površine zabeležen je u proizvodnji šećerne repe, 27848,9 MJ ha-1 dok je najmanje energije utrošeno kod soje, 11371,28 MJ ha-1. Proizvodnja šećerne repe je energetski najproduktivnija (1,58 kg MJ-1). Najviše energije, kod manipulacije i aplikacije đubriva, je utrošeno u proizvodnji pšenice, 14,54 MJ ha-1, a najmanje u proizvodnji soje, 3,23 MJ ha-1. Statistička analiza je pokazala da postoji korelacija između energije utrošene preko đubriva i samog prinosa ratarskih kultura. Funcionalna veza između inputa putem đubriva i prinosa je jaka u svim slučajevima osim kod soje. Regresione jednačine pokazuju pozitivnu zavisnost između prinosa i uložene energije preko đubriva, osim u slučaju pšenice i semenskog kukuruza.

AB  - Mineral fertilizers have a pivotal role in contemporary agricultural production, especially when seeking to exploit the full biological potential of crops. This paper presents the results of a three-year experiment on the distribution uniformity of different mineral fertilizer application systems. One of the objectives in this study was to define the physical and mechanical properties of four different types of mineral fertilizers and examine their changes during storage, transportation and application. A total of four fertilizers were taken into account: UREA, CAN, MAP and NP. The main physical properties, i.e. particle size, particle size distribution, friction coefficient, angle of repose and particle resistance, were analyzed on samples collected from the storage, the trailer (prior to application) and the field (after application). The results obtained show that fertilizers with a particle size distribution of 3.3 to 4.75 mm exhibit higher values of the angle of repose, friction and resistance. The lowest value of the angle of friction (17.53 0) was observed in the UREA fertilizer after application, whereas the highest angle of friction (24.37 0) was measured in the MAP fertilizer obtained from the storage. The values of the static repose angle varied depending on the fertilizer type and the place of sampling (storage, trailer or field). The lowest value of the static repose angle (30.34 0) was measured in the MAP fertilizer after application, whereas the highest static repose angle (36.91 0) was measured in the NP fertilizer from the storage. The NP fertilizer exhibited the highest value of the dynamic friction angle, whereas the lowest value of the dynamic friction angle was calculated for the UREA fertilizer. The NP fertilizer particles showed the highest resistance, whereas the UREA fertilizer particles were most susceptible to breakage.

AB  - Agricultural production is of a great importance for the human population being the major source of food for the population of the planet, whose number is increasing daily. The objectives of this study are the evaluation of the energy embodied in the process of fertilizer application in the sugar beet and soybean production and identification of the energy input-output relation. Data from three production season were collected and analysed. In the case of both cultures results show that the highest share in total energy consumption has the energy input through the application of fertilizers. The nitrogen content in total energy consumption in sugar beet production was 51.89%, 38.44% and 31.83%; phosphorus was 1.77%, 3.66% and 4.18%; potassium was 3.09%, 5.24% and 2.87%. In soybean production the nitrogen content in the energy balance through the seasons was 37.86%, 39.55% and 39.38%; phosphorus was used in first and last season, with content of 4.69% and 3.46%; potassium was used in second agricultural year with the content of 2.30%. Based on the data obtained, it was concluded that the use of fertilizers is very important for the sustainability of agricultural production and that it must be balanced concerning the negative impact of excessive amounts on the both production economy and ecology.

abstract = "Agricultural production is of a great importance for the human population being the major source of food for the population of the planet, whose number is increasing daily. The objectives of this study are the evaluation of the energy embodied in the process of fertilizer application in the sugar beet and soybean production and identification of the energy input-output relation. Data from three production season were collected and analysed. In the case of both cultures results show that the highest share in total energy consumption has the energy input through the application of fertilizers. The nitrogen content in total energy consumption in sugar beet production was 51.89%, 38.44% and 31.83%; phosphorus was 1.77%, 3.66% and 4.18%; potassium was 3.09%, 5.24% and 2.87%.

AB  - The main purpose of man's activities in crop production is to provide such a final product which will, by its quality and quantity, meet the basic principles of cost-effective and cost-efficient production. High yields are leaving soli with the lower productivity and with much worse physical and mechanical properties. In this sense, application of fertilizers is of a great importance. The aim of this study was to demonstrate how much the uniformity of distribution depends of the applied fertilizers physical-mechanical properties and technical system of application. The paper gives the results of two centrifugal spreaders working quality in relation to physical and mechanical properties of applied fertilizers. Variation coefficients showed that no good uniformity was achieved. Real application varied significantly along the swath having the oscillations from 82% lower to 56% higher than the nominal application rate.

AB  - Proper choice and efficient utilization of various technological-technical application systems still has a significant importance concerning ecology, energy and economy in agriculture. Due to the predominant practice of using granulated mineral fertilizers an analysis of mineral fertilizer processing including its production, manipulation and application was made. Physical and mechanical characteristics of mineral fertilizers and fertilizer reaction with the application systems are of outmost importance in fertilizer application system choice. Successful utilization of mineral fertilizers predominantly depends upon the interaction between mineral fertilizers physical-mechanical characteristics and the appropriate type of spreader. The aim of this paper was to analyze working quality of two centrifugal spreaders in relation to physical properties of applied fertilizers in the conditions of seed-bed preparation for corn seeding.

Dominantna praksa korišćenja čvrstih mineralnih đubriva (granulata) nameće celovitu analizu procesa mineralnih đubriva koji podrazumeva proizvodnju, manipulaciju i aplikaciju. Interakcija fizičko-mehaničkih svojstava mineralnih đubriva i tipa rasipača od presudnog je značaja za uspešnost primene ovih đubriva. Cilj ovog rada bila je analiza kvaliteta rada centrifugalnih aparata u kontekstu fizičko-mehaničkih osobina primenjenih đubriva. Ispitivanjem su obuhvaćena dva rasipača centrifugalnog tipa tokom predsetvene pripreme za setvu kukuruza.
