It is important to address metabolic and heavy metal issues in organic waste through sustainable development, circular economy principles and effective solid waste management, particularly focusing on composting as a crucial approach recognized in Morocco’s Green Generation Plan to reduce waste sent to landfills and mitigate greenhouse effects and gas emissions to fight against environmental pollution. This study aims to elevate the significance of organic waste in agriculture by employing composting technics, thereby mitigating its heavy metal content and safeguarding soil and farmland against various forms of contamination. This approach aligns seamlessly with the principles of sustainable development and the circular economy, advocating for responsible waste management and the augmentation of natural resource value. The findings of the study indicated a decrease in heavy metal levels across all composts, with a minimum values at the end of the composting in Gr compost recorded in all heavy metals analyzed (Pb – 0.1125 mg·kg-1, Cd – 0.08 mg·kg-1, Cr – 2.22 mg·kg-1, Zn – 10.88 mg·kg-1, Mn – 28.85 mg·kg-1, Cu –8.30 mg·kg-1, Fe – 545.18 mg·kg-1 and Ni – 1 mg·kg-1). The findings from the assessment of heavy metal levels in the examined compost samples demonstrate their adherence to regulatory standards. Consequently, these composts can be confidently employed as organic soil enhancers, contributing to the enrichment of agricultural soils and fostering plant growth, all while avoiding the potential hazard of undue metal contamination. This study comes to confirm and consolidate previous works findings regarding the valorization of organic solid waste through composting and to minimize their major environmental risks by reducing trace metal elements through this biological process.

Long-term unsystematic use of near-settlement pastures in the desert zone of South Kazakhstan had a negative impact on the physic-chemical parameters of Calcisol. Excessive grazing leads to trampling of soil and reduction of soil fertility. The aim of the study was to develop a technology to improve the productivity of degraded near-settlement pastures. The tasks of the research were to determine the effect application of environmental safe biostimulator and biofertilizer on microbial communities, the content of carbon and phosphorus in the soil, the effectiveness of biostimulator application on degraded pastures in order to increase green mass. For this purpose, geobotanical, bacteriological and helminthological methods of analysis were used. The result of the used proposed technology is the activation of soil microorganisms, which leads to the prevention of degradation of arid pastures. The results of the conducted research contribute to the introduction of a better technology to increase the productivity of arid near-settlement pastures. Statistical analysis of the experiments showed that all manipulations on soil microorganisms increase the number and green mass of arid plants.

Insufficient number of bio-fertilizers is one of the major problems in organic fruit production in Poland. The lack of nitrogen fertilizers that can be used in organic orchards is particularly noticeable. The aim of the study was to determine the influence of several organic fertilizers on tree growth and yielding, and fruit quality in the apple cultivar “Ariwa” grown organically. The study was conducted in 2009-2013 in the Experimental Orchard of the Institute of Horticulture in Dąbrowice (central Poland). An experiment was set up to assess the suitability for organic cultivation of the following bio-fertilizers: Micosat, BF Amin, BF Quality, Humus UP, Humus Active + Aktywit PM, Tytanit, and Vinassa. The fertilizers were compared with the control combination without any fertilization (combination 1). The fertilizers were applied annually, beginning in 2009, twice a year. Most of the tested bio-fertilizers produced a positive effect on the growth and productivity of ‘Ariwa’ apple trees. Some of them also improved the quality of the fruit. The most promising fertilizers proved to be: Humus UP and Humus Active + Aktywit PM, and also BF Amin, Tytanit, and Vinassa.

The current state of phosphorus-containing waste and the methods of its disposal remain relevant. The storage of phosphorus-containing waste sludge is carried out in sludge collectors, which occupy large areas. With the disposal of slags and sludge, as well as the elimination of sludge collectors, the harmful effect of waste on the soil will cease, and the possibility of using these areas for economic land use will appear. Many studies show the movement of phosphorus in soil and water, thus proving the difficulty of disposing of this waste. Of course, phosphorus slags and sludge are used in small quantities in the production of building materials, but this does not solve all the problems. In the south of Kazakhstan, there are warehouses for the waste from the production of phosphorus-containing fertilizers, which also require disposal. One of the ways of modern utilization of these wastes is their use in fertilizers for agriculture. However, since the phosphorus-containing waste has a high content of phosphorus, compared to nitrogen and potassium, this ratio can be changed with the addition of chlorella biomass. The purpose of the conducted study was to investigate the possibility of using a complex of phosphorus waste and algae, that is, the cultivation of chlorella at various concentrations of phosphorus-containing waste for further use of the suspension in watering the test plant. In the form of a test plant, tomato seeds were chosen, the cultivation of which in agriculture is economically profitable. When cultivated in closed ground, tomatoes lose their taste, which can be restored with the use of organic fertilizers. This article shows the results of the influence of various concentrations of phosphorus waste and green microalgae on the growth and development of Solanum lycopersicum.

Biofertilizers are the special formulation of specific beneficial microorganisms that promote the growth of plant crops by converting the unavailable form of nutrients into available form. Here, the effect of heavy metal stress on antioxidant enzymes were studied in Clitoria ternatea L. leaves. Clitoria ternatea L. plant was grown for 30 days and the heavy metal mercuric chloride was sprayed after 10 days from the date of planting. Effect of mercuric chloride was observed in treated plants. The selected plant Clitoria ternatea L. was grown under mercuric chloride treatment in a specified concentration 1 μg/10 ml. The control plant maintained without the treatment of mercuric chloride. Antioxidant effect of mercuric chloride was measured under controlled and treated conditions. The selected plant Clitoria ternatea L. was grown under mercuric chloride in treatment. Further it increases H2O2 content and the antioxidant enzyme activities such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) were observed in mercuric chloride treated plants when compared with control. Here mercuric chloride was accumulated more in matured leaves. The results are discussed with the literature.

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.

The aim of this work was to explore the possibilities of utilising the macroalgae accumulating on the Sopot beach, a part of the Gulf of Gdańsk (Baltic Sea). During this work (2004–2006) a range of activities were undertaken: monitoring the occurrence of macroalgae, collection of plant material, taxonomic identification, laboratory analyses of contamination (metals – Cd, Pb, Ni, Zn, Cu, Cr, Hg; radionuclides – 137Cs, 40K; organic contaminants – polychlorinated biphenyls, polycyclic aromatic hydrocarbons), the stage of algal degradation and studying possible uses of the plant material collected on the beach. The most suitable way of utilising the plant material seems to be as a biofertiliser. Laboratory growth tests were carried out to assess this possible use; they were successful.

Przedstawiono wyniki doświadczenia mającego na celu ocenę skuteczności, nowego bionawozu fosforowego w testach kiełkowania w początkowej fazie wzrostu roślin. Do produkcji bionawozu wykorzystano kości drobiowe, surowiec fosforowy niskiej jakości oraz bakterie solubilizjące fosfor Bacillus megaterium. Bulion pohodowlany poddano neutralizacji i wykorzystano do nawożenia rzeżuchy. Przygotowano próby z różnymi rozcieńczeniami nawozu (dawka fosforu 11,6–44,6 mg P₂O₅/szalkę), kośćmi i próbę nienawożoną jako kontrolę. Odnotowano korzystny wpływ bionawozu na masę roślin (o 44% większą w przypadku dawki bionawozu 11,6 mg P₂O₅/szalkę w porównaniu z próbą kontrolną), na ich wysokość (o 13%) oraz na intensywność barwy zielonej. Zaobserwowano również największą biodostępność fosforu dla roślin z szalki nawożonej dawką 11,6 mg P₂O₅ (37,1%). Wykazano synergizm dawki fosforu w nawozie z zawartością B, Ca, Co, K, S i Si w roślinie a także z suchą masą i wysokością roślin oraz intensywnością barwy zielonej. Testy kiełkowania stanowią potwierdzenie, że nowy bionawóz z bakteriami solubilizującymi fosfor może być wykorzystany jako zawiesinowy preparat doglebowy.

Digestate, as bio-degradable agricultural biogas waste may be subject to the direct management as a fertilizer or, after separation of the solid and liquid phase – solid phase may be subjected to thermo-chemical transformation to biochar. Biochar is a carbonization product with high carbon concentration and relatively low decomposition susceptibility, obtained from various types of organic waste (International Biochar Initiative). Biomas carbonization takes place in the torrefaction process in the temperature from 200ºC to 320ºC. The chemical composition and utility properties of biochar depend on the substrate type and the process parameters. Biochar obtained from biodegradable waste may be an element of carbon biosequestration and used as biofuel, whereas in agriculture – as soil improver, which decomposes for a long time and which positively influences soil fertility, number of biogenic components and physical and water properties. The paper presents characteristic of the torrefaction process, process products and utility values of biochar from the point of view of energy and the agricultural value.

Biowęgiel jest karbonizatem o wysokiej koncentracji węgla i względnie małej podatności na rozkład, pozyskany z różnego rodzaju odpadów organicznych (International Biochar Initiative). Uwęglenie biomasy następuje w procesie toryfikacji w temperaturze od 200ºC do 320ºC. Skład chemiczny oraz właściwości użytkowe biowęgla uzależnione są od rodzaju substratu oraz parametrów procesu. Pozyskiwany z odpadów biodegradowalnych może być elementem biosekwestracji węgla i wykorzystany jako biopaliwo, zaś w rolnictwie – jako długo rozkładający się polepszacz gleby pozytywnie wpływający na żyzność gleby, zasobność w składniki biogenne oraz właściwości fizyczne i wodne. W pracy przedstawiono charakterystykę procesu toryfikacji, produkty procesu oraz walory użytkowe biowęgla z punktu widzenia wartości energetycznej i rolniczej.

Nigella sativa is an annual flowering plant, native to Iran and other parts of southwest Asia, belonging to the buttercup family (Ranunculaceae). Its grain has several important health-related properties such as anti-parasitic, anti-virus, anti-bacterial, increased milk production, carminative, and anti-diabetic. To determine effects of fertilizer treatments on this plant, this experiment was conducted in randomized complete block design in three replications with seven treatments. Fertilizer treatments consisted of Bio phosphor (B 2 kg∙ha-1), Bio sulphur (S 5 kg∙ha-1), Biological fertilized phosphate BAVAR 2 (F 100 g∙ha-1), chemical fertilizer (M) according to soil analysis, and combined fertilizer (B+S), (S+F), and (C) treatment. The application of fertilizers showed a significant effect (p<0.01) on plant height, number of capsules per plant, seed weight, grain yield (g/m-2), number of flowers per plant, and biological yield (g/m-2). There were no observed significant differences (p<0.01) on the number of seeds per capsule, seed weight and yield between chemical fertilizer and biological BARVAR 2. Thus, it can be concluded that there is no preventative for biological fertilizer to produce a good yield of biological product for human health.

Nigella sativa (czarnuszka siewna) jest jednoroczną rośliną kwitnącą występującą w Iranie i innych częściach Azji południowo-zachodniej. Należy do rodziny jaskrowatych (Ranunculaceae). Jej nasiona mają wiele właściwości prozdrowotnych: działają przeciwpasożytniczo, przeciwwirusowo, przeciwbakteryjnie, zwiększają produkcję mleka, działają wiatropędnie i przeciwcukrzycowo. By określić efekty nawożenia tej rośliny, przeprowadzono doświadczenie w czterech randomizowanych blokach, w trzech powtórzeniach przy użyciu siedmiu mieszanek nawozów. W skład zastosowanych mieszanek wchodziły: biofosfor (B 2 kg.ha-1), biosiarka (S 5 kg.ha-1), nawóz biologiczny fosfat BAVAR 2 (F 100 g.ha-1), nawóz chemiczny (M) odpowiednio do analizy gleby i nawóz mieszany (B+S), (S+F), oraz kontrola (C). Wynikiem zastosowania nawozów było wyraźne zwiększenie wysokości roślin (p<0.01), zwiększenie liczby torebek nasiennych w roślinie i plonu (g/m-2). Nie zaobserwowano wyraźnych różnic w liczbie nasion w torebce nasiennej, wadze nasion i plonie pomiędzy roślinami nawożonymi chemicznie i za pomocą nawozu biologicznego BARVAR 2. Zatem można stwierdzić, że nie ma przeciwwskazań do stosowania nawozu biologicznego przy produkcji surowca dla potrzeb zdrowotnych.

In recent years, biofertilisers have emerged as a promising component of an integrated nutrient supply system in agriculture. The objective of this study was to examine the influence of selected biofertilisers on the vegetative growth, the content of N, P2O5 and K2O in the leaves and stems, and on the physiological parameters of pepper of the variety of ‘Sofiiska Kapiya’ cultivated under organic agriculture conditions. This experiment was carried out from 2009 to 2011 on the experimental fields of the Agroecological Centre at the Agricultural University-Plovdiv (Bulgaria), situated on the territory of a certified ecological farm. The study included the following biofertilisers – Boneprot, Lumbrical, Baikal EM “Effective Microorganisms”, Emosan, and Bio One. The results of the biometric measurements of the average plant height at the end of the vegetative period showed the highest values for the variant treated with Emosan on the Boneprot basic fertilisation (62.60 cm – 2009; 64.80 cm – 2010, and 63.87 cm – 2011). Upon feeding with the biofertilisers Emosan and Baikal EM on basic fertilisation with Boneprot (2009, 2010 and 2011) at the pepper mass fruit yield stage, plants showed higher values of net photosynthesis (PN) that were also similar to the high values observed in the flower bud stage. The highest intensity of transpiration (ȿ) was observed for the variants treated with the biofertilisers Baikal EM (2009 and 2011) and Emosan (2010) on basic fertilisation with Boneprot. It was concluded that the feeding with Emosan stimulated the vegetative growth of the pepper plants due to the high concentrations of nutrient-providing proteins contained in this biofertiliser. The results showed that biofertilisers do not significantly impact the P content of the pepper leaves and stems, but changes were more obvious in the leaves. The fertilisation with the studied biofertilisers increased the K2O content in leaves and stems compared to the control (non-fertilised) plants; the values were higher for the leaves.

W ostatnich latach bionawozy pojawiły się w rolnictwie jako obiecujący element zintegrowanego systemu dostarcznia składników odżywczych. Celem niniejszego badania było zbadanie wpływu wybranych bionawozów na rozwój wegetacyjny i zawartość N, P2O5 oraz K2O w liściach i łodygach, a także na parametry fizjologiczne papryki rocznej odmiany ‘Sofiiska Kapiya’ uprawianej w warunkach rolnictwa organicznego. Doświadczenie przeprowadzono w latach 2009–2011 na polach doświadczalnych Ośrodka Rolniczo-Ekologicznego Uniwersytetu Rolniczego Plovdiv (Bułgaria) położonych na certyfikowanej farmie ekologicznej. Badanie dotyczyło następujących bionawozów: Boneprot, Lumbrical, Baikal EM “Effective Microorganisms”, Emosan oraz Bio One. Wyniki pomiarów biometrycznych przeciętnej wysokości rośliny pod koniec okresu wegetacyjnego wykazały największe wartości dla odmiany, której aplikowano Emosan przy podstawowym nawożeniu Boneprotem (62,60 cm – 2009; 64,80 cm – 2010 oraz 63,87 cm – 2011). W przypadku podawania bionawozów Emosan i Baikal EM przy podstawowym nawożeniu Boneprotem (2009, 2010 oraz 2011) na etapie plonowania owoców papryki, rośliny wykazywały wększe wartości fotosyntezy netto (PN). Wartości te były podobne do dużych wartości zaobserwowanych na etapie pąków kwiatowych. Największą intensywność transpiracji (E) zaobserwowano u odmian, którym podawano bionawozy Baikal EM (2009 i 2011) oraz Emosan (2010) przy podstawowym nawożeniu Boneprotem. Wyciągnięto wniosek, iż zastosowanie Emosanu stymuluje wzrost wegetacyjny roślin papryki ze względu na wysokie stężenia białek dostarczającyh elementów odżywczych zawartych w tym bionawozie. Wyniki wykazały, że bionawozy nie wpływają w sposób istotny na zawartość P w liściach i łodygach papryki, ale zmiany były bardziej oczywiste w liściach. Nawożenie badanymi nawozami zwiększało zawartość K2O w liściach i łodygach w porównaniu z kontrolą (rośliny nienawożone), a wartości te były większe dla liści.

Odpad pofermentacyjny można wykorzystywać bezpośrednio na pola uprawne jako materiał nawozowy, tylko i wyłącznie w określonych terminach. Fakt, iż biogazownia rolnicza pracuje bez przerwy, powoduje konieczność magazynowania osadu w postaci nieprzetworzonej w lagunach o pojemności kilkuset m3. Wszelkie wahania parametrów podczas pracy biogazowni rolniczej może generować powstawanie osadów pofermentacyjnych o niecałkowitym przetworzeniu materii organicznej. Tu nasuwa się kolejna problematyczna kwestia odpadów po fermentacji metanowej. Nieprzetworzony poferment często charakteryzuje się nieprzyjemnym zapachem, a wprowadzanie go do środowiska niesie za sobą zagrożenie zanie-czyszczenia gleby, głównie dużą ilością bakterii fermentacji metanowej [7].

Development of substance digestate is next acquisition substrates biggest challenge in the operational management of agricultural biogas plant. Waste digestate can be used directly on the fields as a fertilizer material, but only in terms of strictly defined. The fact that farm biogas plant running continuously contributes to the need to store the sludge in the form of unprocessed (semi-liquid, where the dry weight is approx. 5%) in the lagoons with a capacity of several hundreds of m3. Any variations in the parameters during operation of agricultural biogas plant can generate the formation of deposits of post-fermentation of organic matter processing incomplete. Here arises another problematic issue of waste on the methane fermentation. Unprocessed poferment often characterized by an unpleasant odor. Entering into the environment untreated digestate carries the risk of contamination of soils, namely the introduction of a large amount of soil bacteria methane fermentation.
