Improving the quality of reclaimed soils requires an active population of microorganisms which can promote plant growth. Increasing the activity of microorganisms can be done by adding nutrients, making agrotechnical soil improvements and by the inoculation of beneficial microorganisms. We investigated the role of fertilizer treatments on plant growth and nitrogen fixation in a pot experiment conducted under green house conditions. Influence of the fertilizer type on numbers of bacteria was also investigated. The seeds were inoculated with the mixture of Azotobacter spp. and Rhizobium spp. The pot experiment was set up with the substrate from the mine spoil (North Bohemia coal basin, the Czech Republic) using Medicago sativa as test plants. The following treatments were used: compost 0, 20, 40, 120, 400, 800 t/ha and mineral fertilizer – ammonium sulphate. The doses of ammonium sulphate were calculated to be equivalent (in nitrogen content) to those doses of compost. Control variants without bacteria inoculation and fertilizers were also included. Inoculation with the mixture of AzotobacterRhizobium spp. significantly increased plant growth and nitrogenase activity. The nitrogenase activity was inhibited by mineral fertilizers in all doses used. The results of the study have proved that compost application stimulated the growth of Azotobacter spp. and Rhizobium spp.

Over 2003-2005 period, a study was performed on the effect of different rates of NPK fertilizer of formulation 8:16:24 + 3% MgO (N1 - 400 kg ha-1; N2 - 600 kg ha-1; N3 - 800 kg ha-1; N4 - 1000 kg ha-1) on development of the soil fungi. The trial was set up in the experimental plum orchard established by Fruit Research Institute Cacak, and the laboratory of Department of Microbiology, Faculty of Agronomy Cacak. Unfertilized soil was used as the control soil. Each of the stated variants was carried out in three replications. The size of the basic plot was 68 m2. The effect of the studied mineral fertilizer rates was determined three times over the growing season, the number of fungi being checked by the indirect rarefaction method on Chapek nutritive medium. The results of the study inferred that the application of mineral fertilizers brought about the decrease in the number of fungi. Of all studied variants, the one with the highest nitrogen rate (variant N4) exhibited the strongest effect. The influence of the fertilizer was highest at the third sampling. Furthermore, the effect was highest in season 2003.

<p>The aim of this study was to investigate the influence of mineral fertilizer, different composts and combinations of compost/fertilizer as soil amendments on a loamy silt Cambisol after a 27-year field trial. Four different composts were used: urban organic waste (OWC), green waste (GC), farmyard manure (MC) and sewage sludge compost (SSC). In addition to plant growth, (physico-)chemical and microbiological changes in soil properties following amendment were analysed: total organic carbon (TOC) and nitrogen (N), soil pH, water holding capacity (WHC), basal respiration (BR), microbial biomass (C<sub>mic</sub>) and microbial community composition. Fertilization promoted plant growth, when SSC or GC in addition with mineral fertilizer were applied compared to control. Concerning the (physico-) chemical properties only minor differences among the treatments were found. Phosphorus concentrations were three times higher in plots receiving SSC and SSC + N  than control or mineral N fertilizer alone and magnesium concentrations in plots treated with SSC were lower compared to soils treated with GC and MC, respectively. The bacterial community exceeded the fungal one in terms of both richness and diversity. Further, bacterial richness, diversity and community composition differed significantly among the treatments, whereas differences in fungal richness, diversity and composition seemed negligible. Our conclusion is that composts produced from various source materials serve as a valuable source for plant nutrients and can partially substitute mineral fertilizers, modulate soil microbial community and increase fertility. This way, they contribute to the mitigation of climate change.</p>

У статті висвітлено результати досліджень тривалості веґетаційного періоду квасолі та окремих його фаз для середньостиглих сортів Мавка, Перлина, Надія залежно від рівня удобрення та інокулювання насіння «Ризобофітом Р» в умовах Закарпаття України. Польовий дослід закладали на колекційно-демонстративному полі у ВП НУБіП України «Мукачівський аграрний коледж» у Закарпатській області на дерново-підзолистих важкосуглинкових ґрунтах. Встановлено, що в умовах Закарпаття веґетація середньостиглих сортів квасолі залежно від сортових особливостей, удобрення та інокуляції насіння варіює від 93 до 113 діб. Збільшення норми внесення мінеральних добрив до N60P20K25 подовжує веґетаційний період сортів квасолі звичайної на 8–13 діб. За передпосівної обробки насіння «Ризобофітом Р» тривалість веґетації та настання фенофаз квасолі звичайної також подовжувалась від 2 до 5 діб. Сорт Надія достигає раніше на 8–10 діб. The article is devoted to the results of the study of the duration of the vegetation period of the beans and its individual phases for mid-late varieties of Mavka, Pearl, Nadiya depending on the level of fertilization and inoculation of seeds by «Risobofit P» in the conditions of Transcarpathia of Ukraine. Field experiments were laid on the collector-demonstration field at the NUPiP of Ukraine «Mukachevo Agrarian College» in the Transcarpathian region on turf-podzolic heavy-soil soils. Mineral fertilizers were introduced in the form of ammonium nitrate (34.4 % N), phosphorous flour (30 % P), kalimagnesia (26–28 % K, 11–18 % Mg); additionally carried out liming of soils at the rate of 3 t/ha. The inoculation of seed beans was carried out on the day of sowing by «Risobofit» (mark P), which contains the symbiotic nitrogen fixing bacteria of the genus Rhizobium phaseoli from the Institute of Agroecology and Nature Management of NAAS. It has been established that in the conditions of Transcarpathia, the vegetation of mid-season varieties of beans varies from 93 to 113 days depending on variety characteristics, fertilization and inoculation of seeds. Hope grade reached earlier than others and the period of vegetation it was 8–10 days shorter. Application of seed inoculation prolonged the period of vegetation of beans varieties compared to variants without seed inoculation on a different background of fertilizer for 3–5 days. The increase in nitrogen fertilizers up to 60 kg/ha prolonged the vegetation of the studied bean varieties for 8–13 days. For the application of nitrogen fertilizers in the normal range from 45 to 60 kg/ha against the background of PK, the vegetation period was the same, both in the variants with and without inoculation. The introduction of nitrogen fertilizers in the normal range from 45 to 60 kg/ha on the background of PK resulted in inhibition of the nitrogenase activity of the tubers on the roots of the studied soybean varieties and the plant nutrition was carried out solely at the expense of mineral fertilizer forms.

In a long field experiment on common black soil, the influence of various fertilization systems and presowing bacterization of seeds on the activity of symbiotic nitrogen fixation in lucerne agrocenoses and crop productivity was studied. Stimulation of the process of fixation of atmospheric nitrogen was observed when mineral fertilizers were used in the doses not exceeding N60P60K60, when they were introduced in the year of sowing. High rates of nitrogenase activity were noted in conditions of aftereffect of manure, compost, organic mineral fertilizer (manure + N30P30K30), as well as systematic use of crop residues in the crop rotation. The plant mass in above variants was characterized by high protein content. At the same time, the greatest influence on protein synthesis was provided by the use of a microbial preparation. The combination of ecologically acceptable agricultural backgrounds with presowing bacterization of lucerne seeds ensured the obtaining of parameters of crop productivity.

Synthetic Fertilizers

Chemical (synthetic) fertilizers used indiscriminately for improved production pose a major threat to long-term soil fertility, the soil environment, and its components. The soil microbial community, however, plays a major and important role in fostering soil health and plant growth. While the use of synthetic fertilizers has a profound impact on plant growth, it also significantly alters the makeup of the microbial community towards a detrimental low, especially N and P fertilizers. Sustainable farming practices can reduce the depletion of natural resources and maintain both productivity and soil fertility. The use of minerals that contain fertilizer nutrients in their native state is a very promising approach to reducing emissions associated with the processing chemical industries. Organic material from natural sources (food waste, manure from livestock, agricultural biomass, etc.) acts as a source of microbial culture and encourages the release of nutrients into the soil during mineral weathering. The combination of nutrient-bearing minerals and their biological weathering agents together with organic matter has the potential to remediate, restore, and sustain depleted agricultural soils. Therefore, in this review, we emphasize the significance of sustaining agricultural productivity and microbial diversity in the rhizosphere, the two vital aspects of modern agricultural systems, through bio-organic mineral fertilizers.

The results of studies of the change in redox potential in the profile of light gray forest surface-gleyed soil on variants with long-term agricultural use without applying fertilizers and mineral fertilizer system solely compared with the soil under the forest are presented. On the basis of the conducted analyzes it was established, that soil tillage without fertilizer application and with mineral fertilizer solely has a different effect on ROP in the profile. In the soil without fertilization (control) as compared to the forest a moderate oxidizing (514 mV) and slightly oxidizing (437 mV) processes are happening. Prolonged application of mineral fertilizers to the soil (N65R68K68) significantly reduced the redox potential of all genetic horizons compared with forest and control without fertilizers. For the given fertilizer system the highest values of ROP were obtained in arable HEgl and underarable HEgl layers: 426 mV and 416 mV respectively. Redox potential sharply decreases with the depth to 398-311 mV, which characterizes processes occurring in the soil profile, as weakly reducing and close to moderately reducing.

Different Doses

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

Purpose. Increasing the uniformity of distribution of mineral fertilizers and other bulk materials due to the stability of their feed from the body to the spreading working bodies using the top feeder. Methods. The following methods are used to achieve this aim: the method of comparing the differences between individual groups of fertilizers, the method of analyzing the properties of a new technical system, the method of functional inventiveness, and the methods of theoretical and analytical mechanics. Results. The traction body of the conveyor of the upper feed of the body fat body machine for mineral fertilizers and other bulk materials was substantiated and the relationship between the height of its scrapers and the distance between them was established, as well as the nature of the mineral fertilizer pressure on the curvilinear wall of the body. In addition, the design of the advanced body fertilizer spreader is justified, which ensures a stable flow of fertilizers from the body due to the improvement of the top feeder. Conclusions. Because of the conducted researches, the advantages of machines equipped with top feeder are found. They create the conditions for the forced feeding mineral fertilizers and other loose materials from the container to the distribution bodies, which is a prerequisite for their evenness on the surface. With this, the imperfection of known machines with the top feeder constrains their introduction into agricultural production. On this account, a more thoroughly constructed solution of the body feeder of the top feed is substantiated, in which the conveyor provides a stable supply of fertilizers from the body with reduced energy consumption during operation.

AbstractVegetable production is an important economic activity and a major source of vitamins, minerals, and income in Ethiopia. However, the production of vegetables is much less developed than the production of food grains in the country. Vegetable production still needs improvement in combating biotic and abiotic threats with innovative technologies. Nowadays, excess use of chemical fertilizers to satisfy the increasing demand for food exerts deadly effects on soil microorganisms and contribute to the deterioration of soil fertility and an increase in atmospheric pollution. Several types of research are still going on to understand the diversity and importance of plant growth promoting rhizobacteria (PGPR) and their role in the betterment of vegetable production. PGPR facilitate plant growth directly by either assisting in the acquisition of nutrients (nitrogen, phosphorus, and other essential nutrients) or regulation of the levels of hormones. Indirectly PGPR decrease the inhibitory effects of various pathogens on vegetable growth and development in the forms of biocontrol agents. Some of the notable PGPR capable of facilitating the growth of vegetables such as potato, tomato, pepper, onion belong to genera of Pseudomonas, Bacillus, Azotobacter, Enterobacter, and Azospirillum. Hence, to optimize vegetable production with reduced input of mineral fertilizers and pesticides, the use of PGPR in vegetable cultivation is recommended.
