Simulation of Granular Organic Fertilizer Application by Centrifugal Spreader

There is no specialized equipment designed to spread granular cylindrical organic fertilizer in the soil. There are also no rational recommendations available on how to spread this type of fertilizer. Mineral fertilizer spreaders are most often used for spreading granulated organic fertilizer. However, these fertilizers are significantly different from mineral fertilizers. Due to these differences, organic granular fertilizers often are spread unevenly, and the fertilizer does not reach the required working width. Furthermore, the rate of spreading is not accurate, and the fertilizer is often crushed too much. The objective of this research is to develop a simulation model for granular organic fertilizer applications with a centrifugal spreader in EDEM (extended distinct element method) software. It is possible to develop a numerical model that corresponds to a real spreader, and to determine the key physical–mechanical parameters for the application of granular organic fertilizer. This model can also be used for evaluating the transverse uniformity of the fertilizer in the field (along the trajectory normal to the machine). The results of this research show that the distance traveled by the fertilizer granules partially depends on the particle size, initial speed, type of fertilizer and the parameters of the spinning discs of the spreader.

The Impact

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

The Given

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.

Organic fertilization in no-tillage system (NTS) has been used in regions milk production, in an order to provide nutrients for crops and provide a destination for high production of animal waste. The aim of this study was to evaluate the chemical attributes of an Oxisol, a function of organic fertilization with liquid manure from dairy cattle (LMDC) and mineral fertilizers. The experiment was conducted under NTS with crop rotation including legumes and grasses. The treatments were distributed in three randomized blocks with factorial arrangement, using three levels of mineral fertilizer (0, 50 and 100 % of the dose recommended for the crops) and four levels of organic fertilizer (0, 30, 60 and 90 m3 ha-1year-1). After six years of fertilizer management of crops, soil was collected from five depths (0-0.05, 0.05-0.10, 0.10-0.30, 0.30-0.50 e 0.50-0.80 m). The samples were determined the chemical pH, H++Al3+, Al3+, Ca2+, Mg2+, K+,electrical conductivity (EC), bases saturation (V), Ca2+/Mg2+ ratio, total organic C (TOC), B, Cl, Fe, Cu, Zn and Mn. The mineral fertilizers acidify the soil, raised the K+, P and EC and, changed the Zn and Cu contents. The organic fertilization with LMDC was a source of nutrients (Ca 2+, Mg2+, K+, P, Zn and Cu), raised the TOC and the EC, and kept the soil acidity attributes (pH, H++ Al3+ and V).

Mineral Fertilizers

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.

Analysis of modern scientific literature and patents has shown the absence of acid-free production technology of a mechanically activated multicomponent mineral fertilizer containing water-holding substances. Experimental researches connecting with mechanochemical activation and physicochemical properties of Karatau phosphorites prove a possibility of development of a new multicomponent mineral fertilizer. Application of inorganic and organic activators considerably improves qualities of fertilizers because the developed fertilizer mixtures contain nitrogen, phosphorus, potassium, humate and microelements. The suggested technology intends to use wastes of coal mining that leads to presence of humates and microelements in the end product. It was determined, that content of total nitrogen, phosphorus and potassium depends on a form of nitrogen-phosphorus-potassium-containing substances. The given article contains data of researches connecting with use of multicomponent mineral fertilizers in field conditions for cotton cultivation on irrigated light sierozems consisting of soil-forming rocks of loess and loess-type clay loams. The research results show the increase of soil’s fertility and cotton’s productivity. Studying of agronomic efficiency of the new kinds of mechanically activated multicomponent mineral fertilizers at the cultivation of a bean-cereal mixture has been carried out in the Negorelsk experimental nursery-garden of the Belarus State Technical University on a sod-podzol sandy-loam soil and has shown the essential influence on productivity and quality of the bean-cereal mixture. The researches fulfilled on a sod-podzol sandy-loam soil have revealed the essential increase of key indicators of feed productivity. Application of the mineral fertilizers has promoted increase of nitrogen, phosphorus and potassium content in green plants. In so doing content of calcium and magnesium in green mass depends from quantity of the fertilizer used to a smaller extent. An essential difference of crop capacity and feed productivity indicators depending on forms of the applied mineral fertilizers has not been found.

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.

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.

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.

Positive Balance

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.
