Opis:
A field experiment was carried out at the Experimental Farm of SEKEM Company in Bilbes, Sharqia Governorate, Egypt during the 2019 season, in order to study the effect of adding compost tea and humic acid on the growth and active ingredient of the chive (Allium schoenoprasum L.) plant. Chive seeds were sown in nursery in August, two months later seedlings were transplanted to permanent soil. The chive plants received two organic fertilizers: the first one was compost tea (0, 100 and 200 ml/L) as main plot, and the second one was humic acid (0, 2 and 4 g/L) as sub plot. The two fertilizers were sprayed twice, 45 and 75 days after sowing. The results revealed that: the applied compost tea significantly increased the growth and yield characteristics as well as oil percentage and yield, compared with untreated plants. The plants treated with compost tea at 200 ml / L produced the maximum mean values of plant height, fresh and dry weights of herb, as well as essential oil yield. However, humic acid at 4 g /L recorded the highest mean values of plant height, fresh and dry weights of herb. On the other hand, humic acid at 2 g/L gave the highest values of essential oil yield. Moreover, the interaction treatments had a significant effect on all traits under study. Thirty compounds of Chive essential oil (EO) were identified by GC-MS analysis, representing from 65.07 to 93.29% of the total EO. The main compounds found were dipropyl disulfide (12.8–35.4%), dipropyl trisulfide (12.9–30.05%), methyl propyl trisulfide (3.80–9.03%) and 1-propenyl propyl disulfide (1.56–10%). The highest amounts of dipropyl disulfide and 1-propenyl propyl disulfide were detected with humic acid at 4 g/L treatment. The treatment of compost tea at 200 ml/L + humic acid at 2 g/L caused the greatest accumulation of dipropyl trisulfide which recorded 30.05%, while the greatest values of methyl propyl trisulfide (9.03%) were recorded as a result of tea compost at 100 ml/L.

Opis:
Water vapour sorption processes on mixtures of soil and organic fertiliser Rosahumus (RH) were investigated. Mixtures were prepared with Orthic Luvisol soil formed from loamy sand and Haplic Luvisol soil formed from loess. Samples contained different doses of fertiliser in the range from 1 to 50 weight percent. Differences in water vapour sorption on Rosahumus (RH) as well as the soils were observed. The properties of soil mixtures and organic material depended on the properties of both components and on the dose of Rosahumus. However, fertiliser was a dominant factor in sorption processes of investigated mixtures. Adsorption isotherms obtained by gravimetric method belonged to the same type II, in accordance to the BET classification. Significantly higher influence on the water vapour sorption was associated with fertiliser dose and was greater for mixtures with soil formed from loess. The increase of water vapour sorption was visibly higher for mixtures below 4% of Rosahumus content. On the other hand, greater concentration of RH resulted in similar amount of water vapour sorption and for Rosahumus dose of 50% the sorption was practically the same. Similar results were found for the maximum hygroscopicity (Mh) of mixtures. Strong correlation was observed between the Mh and the amount of added organic fertiliser with determination coefficient (R2) from 0.997 to 0.998.
Badano proces sorpcji pary wodnej na mieszaninach gleby i nawozu organi-cznego Rosahumus (RH). Mieszaniny sporządzono z gleby pseudobielicowej wytworzonej z piasku gliniastego i z lessu. Próbki mieszanin zawierały dawki nawozu od 1 do 50% wagowych, zgodnie z definicją stężenia procentowego. Badane gleby i Rosahumus wyraźnie różniły się zachowaniem wobec pary wodnej. Właściwości badanych mieszanin zależały od właściwości obu składników i wielkości dawki Rosahumusu. Jednakże nawóz był dominującym komponentem, który determino-wał właściwości mieszanin w procesie sorpcji. Izotermy sorpcji pary wodnej, otrzymane metodą grawimetryczną, zaliczono do grupy II według klasyfikacji BET. Stwierdzono, że ilość zasorbo-wanej pary wodnej zależała od wielkości dawki nawozu i była większa dla mieszanin gleby wytworzonej z lessu niż piasku gliniastego. Wyraźne zróżnicowanie w ilości zasorbowanej wody było widoczne dla mieszanin zawierających do 4% Rosahumusu. Dla wyższych dawek RH, różnice w ilości zasorbowanej pary wodnej były małe, a dla dawki 50% praktycznie zanikły. Podobne zależności stwierdzono dla maksymalnej higroskopijności mieszanin, gdzie obserwowano silne zależności pomiędzy Mh i dodatkiem Rosahumusu, R2 od 0,997 do 0,998.

Opis:
Bulb fennel (Foeniculum vulgare Mill.) has gained importance for its high-value bulb production. A field experiment was conducted in a farm in El-Santa, Gharbia, Egypt, to enhance productivity and quality attributes of F. vulgare bulbs using different fertilizers: biofertilizer, organic fertilizer (rabbit manure), and mineral fertilizer [nitrogen (N), phosphorus (P), and potassium (K)]. The biofertilizers included nitrogen fixer bacteria (Azos), phosphate solubilizing bacteria (Bm), and potassium solubilizing bacteria (Bc) with/without vesicular arbuscular mycorrhizal (VAM) fungi. Application of NPK at 150% of the RD and rabbit manure at 60 m3/fed resulted in the highest values of branch number, bulb weight, bulb yield, percentages of total carbohydrates, N, P, and K, as well as features of marketable bulbs including firmness, total soluble solids, titratable acidity, vitamin C, and bulb essential oil. Moreover, the GC/MS analyses of bulb essential oil of the organically and chemically fertilized plants showed the increase of trans-anethole, the predominant constituent responsible for bulb’s flavor. However, the highest proportion of estragole (9.65%), an undesirable compound, was recorded with 150% of recommended NPK. In comparison, the lowest estragole content (4.09% and 5.64%) was obtained by organic fertilizer (rabbit manure at 60 m3/fed) and biofertilizer (Azos+Bm+Bc+VAM), respectively. The increase in bulb yield (11.76–11.99 ton/fed) and essential oil content (0.076–0.080%) of bulbs obtained with organic manure (rabbit manure at 60 m3/fed) was accompanied by a marked decrease in estragole and an increase in the most important constituents, α-pinene, ß-pinene, limonene, trans-anethole, and anisaldehyde. Hence, the organic fennel bulb can be produced with an abundant and highquality crop which consolidates the concept of ecological and organic farming for this important crop.

Opis:
Herein, the effect of applying different rates of inorganic fertilizer (NPK 20:10:10) and organic fertilizer (neem seed) and their combinations on plant nutrient concentration and yield of okra was studied under field conditions at two locations within the University of Calabar Teaching and Research Farm. The experiment was laid out in a randomized complete block design with three replications. Eleven treatments were applied. These were comprised of a control (no amendment), sole NPK 20:10:10 fertilizer and neem–based organic fertilizer applied at two rates (100 and 120 kg N/ha), combinations of 60 kg N/ha NPK+ 60 kg N/ha Neem, 50 kg N/ha NPK+ 50 kg N/ha Neem, 90 kg N/ha NPK + 30 kg N/ha Neem,25 kg N/ha NPK+ 75 kg N/ha Neem, 30 kg N/ha NPK + 90 kg N/ha Neem and 25 kg N/ha NPK+ 75 kg N/ha Neem. Amongst the two rates (100 and 120 kg N/ha) of sole application of either NPK or Neem-based organic fertilizer, the 120 kg N/ha recorded the highest number of fruits set and okra fresh fruit yield. The combination of 60 NPK + 60 Neem kg N/ha increased the yield (8.43 t/ha) and yield components of okra, while the 90 NPK + 30 Neem kg N/ha and 30 NPK + 90 Neem kg N/ha increased nutrient concentration in the okra plant. Thus, for sole application, the 120 kg N/ha application of either nutrient source is appropriate, but for optimum yield of okra in the tropical rainforest zone of Nigeria, the combination of both organic and inorganic fertilizer especially at 60 kg N/ha of each nutrient source, is recommended.

Praca przedstawia bilans azotu w 78 wybranych gospodarstwach rolnych trzech gmin regionu leszczyńskiego. Badania obejmowały określenie: obsady zwierząt, produkcji azotu w nawozach naturalnych, bilans azotu dla gospodarstw, jak i uprawianych roślin. Produkcja azotu w nawozach naturalnych i jego bilans były porównywane z regulacjami obowiązującymi w Polsce. Stwierdzono, że w badanych gospodarstwach obsada zwierząt była wysoka (w 67,9% gospodarstw ponad 1 DJP) i w czterech gospodarstwach produkcja azotu w nawozach naturalnych i stosowane jego dawki przekraczały dopuszczalną ilość 170 kg/ha UR. W 33 gospodarstwach (42,3% ogółu gospodarstw) dodatnia różnica bilansowa azotu (wprowadzonego w nawozach naturalnych i mineralnych minus pobranego w plonach roślin) była większa niż dozwolona 30 kg/ha UR. Spośród uprawianych roślin w badanych gospodarstwach największe dodatnie różnice bilansowe stwierdzono w przypadku uprawy buraków pastewnych, ziemniaków, jęczmienia ozimego i jarego.
In the paper the balance of nitrogen in seventy eight selected farms of three communities of Leszno region is presented. Results concern: livestock density, production of nitrogen in animal organic fertilizers, balance of nitrogen in farms as well as for cultwated plants. Production of nitrogen in animal organic fertilizers and its balance were compared to regulation in force in Poland. It has been stated that in examined farms the livestock density was high (in 67,9 % of farms over 1 large livestock unit) and in four farms the production of nitrogen in animal organic fertilizers and it's applied doses were larger than allowed quantity of170 kg per 1 ha of agriculturally utilized area. In 33 farms (42,3 % of total farms) the positive balance difference of nitrogen (brought in organic and mineral fertilizers minus uptake in yields of plants) was larger than allowed 30 kg/ha ofUAA. Among cultivated plants in examined farms the highest positive balance value of nitrogen was stated in case of fodder beet, potato, winter and spring barley cultivation.

Opis:
Recently the use of organic fertilizers is increased to raise the agricultural products and reclaim land for cultivation in the world. These fertilizers contain many natural radionuclides, such as Uranium series (U-238), Thorium series (Th-232), and Potassium (K-40). Organic fertilizers can be considered as one of the natural sources of radiation in the soil. The specific activities of natural radionuclides U-238, Th-232, and K-40 in organic fertilizers were measured using a gamma-ray spectrometer NaI(Tl) detector and Rad Eye-B20 portable detector. Results of NaI(Tl) detector showed that the mean value of activity concentrations of U-238, Th-232, and K-40 was 2.101 Bq/kg, 0.329 Bq/kg, and 95.791 Bq/kg, respectively, were less than the recommended limits. The mean value of radiometric parameters Raeq, Hin, Hex, Iγ, Iɑ, DƔ, and AEDE were also calculated (9.398 Bq/kg, 0.0355, 0.0249, 0.037, 0.0123, 4.959 nGy/h, 0.0065 mSv/y). But the maximum and minimum values of activity concentration were found in sample O.2 and O.4, respectively. The results of Rad Eye-B20 portable detector showed that the maximum (0.415 Bq/cm2, 0.17 µSv/h, and 1.055 Cps) and the minimum (0.255 Bq/cm2, 0.13 µSv/h, and 0.485 Cps) values of surface contamination, Dose Rate, and General Count Rate per second were respectively found in samples O.2 and O.4; all they were slightly higher than background measurements (0.21 Bq/cm2, 0.12 µSv/h, and 0.44 Cps). Measurements of NaI(Tl) detector were matched and confirmed by Rad Eye-B20 detector. All measurements of the radiological hazard to consumers were less than the recommended limits.

Osady denne zalegające w zbiornikach wodnych stwarzają zagrożenie środowiskowe i żeglugowe utrudnienia techniczne, ale po wydobyciu stanowią cenny nawóz organiczny. Dotychczas stosowane metody wydobywania osadów lub ich neutralizacji są drogie i nie zawsze w pełni skuteczne. W Instytucie Technologiczno-Przyrodniczym opracowano technologię wydobywania osadów dennych o koncentracji suchej masy do 30%, co umożliwiło wykonanie modelu urządzenia i jego sprawdzenie w praktyce. Badania składu wydobytych osadów ze stawów rybnych w Falentach i badania wazonowe oddziaływania mieszanek nawozów organicznych opracowanych na bazie tych osadów na wzrost roślin wykazały skuteczność porównywalną z działaniem obornika [EYMONTT i in. 2017]. W związku z powyższym planuje się dalszy rozwój i wdrażanie do praktyki opracowanej technologii wydobycia osadów oraz produkcji nawozów organicznych.
Bottom sediments, on the one hand, in reservoirs, pose environmental threats and shipping technical difficulties, but on the other hand, after extraction, are valuable organic fertilizer. Existing methods of sediment extraction or neutralization are expensive and not always effective. The technology developed by the Institute of Technology and Natural Resources for the extraction of bottom sediments with a concentration of dry matter up to 30% enabled the model to be made and tested in practice. The study of the composition of the extracted fishpond sediment in Falenty and the study of the effect of mixtures of organic fertilizers prepared on the basis of these sediments on the growth of plants showed the effectiveness comparable with the effect of manure. As a result, further development and implementation of the developed sediment extraction technology and the production of organic fertilizers are planned.

The aim the research is to estimate the influence of granulated organic-mineral fertilizers formed from spent mushroom substrate (SMS) on the common cabbage crop. Fertilizers and composted spent mushroom substrate are using on two doses on account of applicationed nitrogen content, these doses are 100 and 200 kg N ha-1. 10 fertilizers combinations on four replications are used in experiment. The test plant was common cabbage. After harvest were estimated yield of green matter and dry matter yield. Statgraphics 4.0. program was using to statistic data processing of the results. Dry matter yield of cabbage depends on the kind and dose of fertilizers applied in the experiment. The greatest yields are obtained from object manured by fertilizer formed from spent mushroom substrate with supplement urea and powdery superphosphate and potassium salt, also fertilizer formed from spent mushroom substrate with supplement ammonium salpeter. Other granuled organic-mineral fertilizers have a positive influence on increasing cabbage yield in comparison to the control object, however, their yield effect is similar.

Opis:
Chicken feathers generated in large quantities by the poultry industry are hazardous for the natural environment because of their poor digestibility and their potential as a source of microbiological pathogens. Currently, the main method of feather waste management is the production of feather meal by steam pressure cooking. This technology requires a high energy input. The high costs of hydrothermal degradation of these wastes are conducive to finding other alternative possibilities of poultry wastes management. This paper describes the feather-utilization method with calcium oxide treatment in a rotational reactor, which leads to the production of organic-mineral fertilizers. The effectiveness of this method has been tested in chemical and microbiological analyses. The results of the study confirm the possibility of the environmental usage of utilization-products.

Opis:
The permanently rising costs of food industry waste management create a real necessity for searching for new economical and environmentally friendly technologies with which such waste can be utilized. The purpose of this study was an evaluation of waste composting using rotational reactor technology with further use of the resultant product as a fertilizer. In order to conduct the research, a rotational reactor was designed and constructed. For the composting process, such waste materials as meat and bone pulp, past its sell-by date dairy and bakery products, sawdust, poultry and cattle manure, were used. The composition of the composted masses was chosen so that their approximate C:N:P proportions and consistency were appropriate for the growth of biodegradating micro-organisms. The efficiency of the presented technology was evaluated based on the inactivation of selected strains of bacteria and the eggs of invasive parasites. The products obtained were tested by the Institute of Soil Science and Plant Cultivation in Puławy with regard to its possible environmental usage.
