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.

AbstractWe steered the soil microbiome via applications of organic residues (mix of cover crop residues, sewage sludge + compost, and digestate + compost) to enhance multiple ecosystem services in line with climate-smart agriculture. Our result highlights the potential to reduce greenhouse gases (GHG) emissions from agricultural soils by the application of specific organic amendments (especially digestate + compost). Unexpectedly, also the addition of mineral fertilizer in our mesocosms led to similar combined GHG emissions than one of the specific organic amendments. However, the application of organic amendments has the potential to increase soil C, which is not the case when using mineral fertilizer. While GHG emissions from cover crop residues were significantly higher compared to mineral fertilizer and the other organic amendments, crop growth was promoted. Furthermore, all organic amendments induced a shift in the diversity and abundances of key microbial groups. We show that organic amendments have the potential to not only lower GHG emissions by modifying the microbial community abundance and composition, but also favour crop growth-promoting microorganisms. This modulation of the microbial community by organic amendments bears the potential to turn soils into more climate-smart soils in comparison to the more conventional use of mineral fertilizers.

<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>

O mamoeiro é umas das plantas frutíferas mais comuns em quase todos os países da América Tropical. Um dos principais problemas na cadeia produtiva da cultura de mamão é obter bom manejo do material propagativo e garantir uniformidade e qualidade de estande, sendo para isso necessária a obtenção de mudas de qualidades fisiológicas e sanitárias adequadas.  A utilização de produtos alternativos vem demonstrando efeitos significativos no desenvolvimento radicular de várias plantas, o que beneficia a formação de um pomar de maneira rápida, homogênea, permitindo assim a antecipação da colheita e maior lucratividade ao produtor. O objetivo deste trabalho foi avaliar o efeito do organomineral em diferentes doses na produção de mudas da cultura do mamoeiro da cultivar Sunrise Solo Line 72/12, em condições de ambiente protegido. O experimento foi conduzido no viveiro de mudas do Centro Universitário de Santa Fé do Sul - UNIFUNEC, Campus II. O delineamento experimental utilizado foi de blocos inteiramente casualizados, com seis tratamentos (0; 0,050; 0,100; 0,200; 0,300 e 0,400 kg tratamento de organomineral) e quatro repetições (6X4), utilizando 5 saquinhos por repetição, totalizando 120 saquinhos. Os dados biométricos analisados foram altura da planta (cm); comprimento da raiz (cm); diâmetro do caule (cm); massa úmida e seca da área foliar (g) e massa úmida e seca da raiz (g), aos 60 dias após plantio. Com base nos dados obtidos dos caracteres agronômicos analisados, conclui-se que o uso das doses 0,050; 0,100; 0,200 e 0,300 kg por tratamento de fertilizante organomineral promoveu a obtenção de mudas de mamoeiro com maior qualidade fisiológica que são imprescindíveis na formação de pomares comerciais.   REVIEW OF DIFFERENT DOSES OF ORGANIC MINERAL FERTILIZERS FOR PAPAYA SEEDLING DEVELOPMENT   ABSTRACT The papaya tree is one of the most common fruit trees in almost all Tropical American countries. One of the main issues in the papaya cultivation production chain is obtaining good management of propagative material and provide uniformity and quality for sales quality assurance, being to this end necessary to obtain physiological and sanitary appropriate seedling. The use of alternative products has demonstrated significant effects on the root development of several plants, benefiting a fast, homogeneous formation of an orchard, resulting in the anticipation of the harvest and higher profitability for the farmers. This paper aims at reviewing the organic mineral in different doses to produce papaya tree seedling from cultivar Sunrise Solo Line 72/12, in environment-protected conditions. The experiment was carried out at the Centro Universitário de Santa Fé do Sul - UNIFUNEC, Campus II greenhouse. The trial design chosen was the completely randomized blocks, with 6 treatments (0; 0,050; 0,100; 0,200; 0,300, and 0,400 kg organic mineral treatment), and four repetitions (6X4), using 5 small bags per repetition, total 120 small bags. Biometric data analyzed was the plant height (cm); root length (cm); stem diameter (cm); wet and dry mass of the leaf area (g), and wet and dry mass of the root area (g), 60 days after planting. Based on the data obtained from agronomic characters analyzed, it was concluded that the use of 0,050; 0,100; 0,200, and 0,300 kg doses per treatment with organic mineral fertilizer provided papaya tree seedling with higher physiological quality which are vital for the commercial formation of orchards.   Keywords: Carica papaya L.

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.

Intensification of horticulture in Russia involves planting of new high-density orchards with drip irrigation and fertigation as well as intensification of the exploitation of traditional orchards. This approach involves an increase in mineral fertilizer application imposing the risk of soil fertility loss. For several reasons, the use of traditional organic fertilizers like manure in orchards is currently marginal. Although bacteria-based biofertilizers cannot substitute mineral fertilizers completely, they can significantly reduce the need for mineral fertilizer application. The effect of microbial biofertilizers of the brands “Azotovit” (Azotobacter chroococcum), “Phosphatovit” (Bacillus mucilaginosus), as well as a mixture of bacteria and the fungus, “Organic” (Azotobacter chroococcum, Bacillus subtilis, Bacillus megaterium, Trichoderma harzian) was studied in two field experiments. In the experiment #1, the preparations “Azotovit” and “Phosphatovit” were delivered through a drip irrigation system in various combinations with mineral fertilizers. In experiment #2, the preparation “Organic” was also applied to the soil with irrigation water, also in combination with the mineral fertilizer. When solely applied, none of the studied preparations changed significantly the soil nutrient content and yield as compared with the variant fertilized by the mineral fertilizer at the maximum studied application rate. The combination of the microbial biofertilizer and mineral fertilizers applied at a low rate ensured the yield commensurate to that obtained under high-rate application of the mineral fertilizer.

A comparative analysis of the seeds ash composition of the breed Rif (Brassica napus L.) rapeseeds grown in the Lipetskaya region was held. The plants were grown in the conditions of the agroecological experiment using mineral (NPK and zeolite) and organic (hen droppings) fertilizers. 6 variants of the experiment were studied – the plants are grown without fertilizers application (the control); the mineral fertilizer (N60:P60:K60) separately and together with zeolite (5 t.ha-1); the zeolite in pure form (5 t.ha-1); hen droppings (5 t.ha-1) separately and together with zeolite (5 t.ha-1). We studied the accumulation of 9 basic elements (in mass %) contained in Brassica napus. seeds ash using the method of energy-dispersive X-ray spectroscopy. The accumulation order of the elements was determined: P ≈ K > Mg ≥ Ca > Mo > S > Zn > Mn > Fe. The proportion of P fluctuated from 10.852 to 11.855 mass %; the proportion of K – from 9.933 till 12.343 mass %. The rapeseeds contained Mg, Ca, and Mo in similar concentrations within the range of 4.0 -5.8 mass %. The combined application of zeolite with organic fertilizer ensured the accumulation of the minerals in the seeds. Correlations between the elements were established. High correlation between elements K and Mo was found (r = 0.96); P and Mg (0.86); P and Fe (r = 0.94); C and Mo (r = 0.86). The positive effect of the combined organic-mineral fertilizers with poultry farms wastes usage on the mineral elements accumulation in rapeseeds was stated. It is noted that the accumulation of P, Ca, Mo, and S in rape seeds leads to a decrease in Zn.

Abstract The most effective doses of the modified organic-mineral fertilizer (MOF), produced from non-contact pig manure in the conditions of the Rostov region for the purpose of soil reclamation, were determined. Experimental studies were carried out to determine the most effective dose of MOF based on non-contact pig manure. The dependence of the spring wheat yield on the use of a modified organic-mineral fertilizer based on liquid waste from pig farms fermented bird droppings and mineral fertilizers is determined. The equivalence of the effect of a modified organic-mineral fertilizer based on liquid waste from pig farms and fermented bird droppings, introduced in an equivalent dose, on plant biomass was established. When comparing the effects of different types of fertilizers, their toxicity was not established. The introduction of a modified organic-mineral fertilizer based on liquid waste from pig farms at a dose of 2 t / ha provided the highest biomass yield of 34-day-old plants of spring wheat of the “Zlata” variety, which reached 0.9 g/vessel and was 28.5% higher than the control value. A new organic mineral fertilizer with a pH of 8-10, with an organic content of up to 73% per dry weight, can be used for supporting the quality of liming and improving soil.

During 2000–2018, the results of the application of organic and mineral fertilizers in dynamics and their effect on the content of humus and nutrients in the soils of the Zaporizhzhya region were reviewed. To control the state of soil fertility use the calculation of the balance of humus and nutrients. This makes it possible to determine the extent to which the application of nutrients with fertilizers covers their removal by crop yields. Negative tendencies have been identified, which have led to the deterioration of soil fertility in the Zaporizhia region. Measures are proposed to achieve a deficit-free balance of humus and nutrients. On average, in 2000–2018, the level of mineral fertilizer application in the Zaporizhia region remained low – 38 kg/ha (nitrogen – 28 kg, phosphorus – 7, potassium – 3 kg), and manure – only 0.2 t/ha. According to the results of agrochemical certification of agricultural lands, the dynamics of changes in the content of humus, easily hydrolyzed nitrogen, mobile compounds of phosphorus and potassium over the past 18 years has been determined. The average weighted content of humus in the soils in the VIII round was 3.44 %, IX – 3.52, X – 3.40, XI (2016–2018) – 3.57 %, which indicates the stability of this indicator. The weighted average nitrogen content, which is easily hydrolyzed during all rounds, has close values (83.6–90.3 mg/kg) and corresponds to a low level of its supply. The content of mobile phosphorus compounds during the VIII – IX rounds was quite stable (97.1–101.6 mg/kg), and in the X–XI rounds there was even an increase to 123.3–123.4 mg/kg. The phosphorus regime of soils is stable and corresponds to the increased level of security, except for the ninth round (average). Potassium regime of the soil for eighteen years also remains stable and refers to a high level of security (159.6–176.8 mg/kg). The balance of humus and nutrients in the soils of the region remains negative. There is a tendency of positive changes if we compare the results for the first (2003–2014) and second (2003–2018) periods. Thus, to achieve a positive balance of humus it is necessary to apply 2 t/ha of straw (+400 kg/ha), 20 kg/ha of nitrogen fertilizers and 6.4 t/ha of manure, and in 2003–2018 – respectively 2 t / ha straw (+400 kg/ha), 20 kg/ha of nitrogen, 5.8 t/ha of manure. Key words: soil, balance, dynamics, humus, fertility, organic and mineral fertilizers.

Increased production of foodstuffs is required in line with increasing population. The tourism sector in Bali needs quality products that are both viable and environmentally friendly. Previous research since 2002-2016, found mineral fertilizer plus can increase the highest production, , increased soil quality, and increased farm income. The research location was in Baturiti Subdistrict. The plant tested was string bean (Phaseolus vulgaris L) during first planting and residual effect of first fertilization (second planting). Eight fertilizer treatments: P0=control, P1=organic, P2= mineral, P3=chemical (NPK), P4=combination ½ (organic+chemical), P5=combination ½ (mineral+chemical), P6= Baliplus mineral fertilizer (BMF) =combination ½ (organic+mineral+chemical), and P7=combination ½(organic+mineral)], three replications. Parameters observed were bean weight, storage capacity, and value of farm income. The experimental designed used was Randomized Block Design, with Duncan's real test difference of 5%, using the Costat program. Fertilization was very influential and significantly affected to the production of the first planting and residual effects. The treatment using BMF in the first crop,resulted in the highest production (34.33 tons ha-1), highest production increase (62.92%), longest storage (36%) for one week, and the highest farm income (Rp 334 million ha-1). The P1 treatment showed the lowest production (25 ton ha-1), the lowest increase (18.45%), storage capacity (15.27%), and the lowest farm income (Rp 28.7 million ha-1). String bean with the highest residual effect (16.17 ton ha-1) was obtained in treatment P4. The average production of the remaining effect is 48.62% of the first crop. The use of mineral fertilizers plus bali can increase production, savings, and farm income, and reduce 50% of the use of chemical and organic fertilizers.

The issue of scientifically sound fertilizer application in fruit plantations, which are long-term and re-grown in one place remains insufficiently studied. To solve this problem is possible only in long-term stationary studies, as the impact of different fertilizer systems on changes in soil properties and tree productivity for a long period of their use. The results of researches of long-term fertilizer influence on the main fertility indices of dark gray podzolic heavy loam soil and productivity of repeatedly grown apple trees of Idared varieties on seed and vegetative (M4) rootstocks and Calville snow on seedling rootstock are considered. During the 85-year period of growing the first and second generation of apple trees in the experimental garden, the organic fertilizer (40 t/ha of cattle manure), mineral fertilizer (N120P120K120) and their combination (20 t/ha of manure + N60P60K60) were applied in the old plantation every two years in autumn in plowing in rows at 18–20 cm, and in the new repetition: manure, phosphorus and potassium fertilizers as well, and nitrogen fertilizer in half doses annually in spring for cultivation or disk plowing to a depth of 12–15 cm. As a result of research it was found that organic fertilizer better than mineral fertilizers provided the formation of soil fertility (humus and mobile compounds and forms of nutrients, soil reaction) and yield capacity of experimental apple trees, which for all years of fruiting exceeded the total yield of Calville snow and Idared on seedling and vegetative rootstocks, respectively, by 34.8, 27.7 and 23.4 % compared with the yield of the control non-fertilized areas and 16.0, 15.8 and 13.2 % – on those fertilized with N120Р120К120. Similar parameters of soil fertility indicators are formed by the organo-mineral fertilizer system with systematic long-term application of half the norms of organic and mineral fertilizers of manure 20 t/ha together with N60P60K60. However, the mineral system (N120P120K120) significantly less increases the humus content and content of macronutrients available for plant nutrition and does not enrich the soil with trace elements, acidifies the reaction of the soil environment
