Although the inceptisol soil in Nawungan has good fertility, it is not very effective in fertilizing plants because a lot of the nutrients are lost due to evaporation or washing away. As a result, new and inventive methods of growing shallots in that region were needed. The purpose of this study was to improve the yield of shallot plants and the efficacy of NPK fertilization of shallot plants by applying biochar and biofertilizer. The study was place at Nawungan 1, Selopamioro Village, Imogiri District, Bantul Regency, Yogyakarta Province, from April to September of 2023. Its coordinates are 7 o 53’03.36” S, 110o 24’37.58” E. In order to create 33 trials, this study used a completely random group design (CRGD) with two factorials of 5 by 2 and one control negative with three repeats. One factor is biochar (B0), followed by biochar rice husk 5 tons·ha-1(B1), biochar rice husk 10 tons·ha-1(B2), biochar shell coconut 5 tons·ha-1 (B3), and biochar shell coconut 10 tons.ha-1(B4). The second element is that without biofertilizer (H0A), without biofertilizer+NPK 400 kg·ha-1(H0B) and with biofertilizer+NPK 400 kg·ha-1 (H1B). The research result showed that treatment application biofertilizer+NPK 400 kg·ha-1+biochar coconut shell capable increase C-organic, N-total, P-available, K-available, growth tall plants, quantity leaves, yield harvest, NPK uptake by plants and increase efficiency NPK fertilization on the Inceptisol.

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.

Microalgae have unique properties that allow them to thrive in unconventional spaces, making them suitable for areas that are not normally suitable for crop growth. This is due to their ability to multiply rapidly, grow easily and adapt to different environments at low cost. As a result, the present study aims to analyze the potential of microalgae as a source of agricultural nutrition, as well as the health benefits they can provide. The following research was conducted on an experimental scale using a closed system (photobioreactor) for the cultivation of microalgae, its physicochemical characterization of the cultures and dry biomass. It can be observed the percentages of 11 N; 1.4 P; 0.3 K and its micronutrients are essential for plant growth, since microalgae-based biofertilizers are considered as a sustainable, cost-effective and environmentally friendly alternative to chemical fertilizers. The use of microalgae biomass as a biofertilizer in agriculture can increase fertility, reduce soil erosion and nutrient loss, and improve soil quality over time. It also benefits plants, vegetables and greens, as it contains nitrogen, phosphorus and potassium, which are necessary for growth.

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.

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.

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.

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 Moroccan olive oil industries generate a substantial amount of olive mill wastewater (OMW), causing a significant environmental issue. Consequently, its valorization represents a sustainable agroecological solution to the environmental problems caused by this uncontrolled discharge. In this context, the use of OMW as an organic biofertilizer in agriculture has been suggested as an alternative to restore soil fertility and improve agricultural production. To comprehensively understand its impact, the conducted study focused on the local cultivar Vicia faba L., investigating the consequences of daily applications of OMW at varying doses (5%, 10%, 20%, 30%). In the experimental design, NaCl solutions, mimicking the electrical conductivity of OMW, were used to pinpoint the potential phytotoxic agents within the wastewater. The results revealed that a high dose of OMW had significant effects on morphological, physiological, and biochemical parameters. Additionally, phytotoxicity depended on both OMW concentration and the growth stage of Vicia faba L., causing growth delays, germination inhibition, as well as the accumulation of proline and soluble sugars. These findings underscore the complexity of using OMW in agriculture and highlight the critical importance of precise control over application rates for the success of this approach. While reusing OMW presents a viable and practical solution, a nuanced understanding of its impact on specific crops and a meticulous approach to dosage management are imperative to realize its potential benefits and mitigate any potential risks to crop productivity.

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.

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.

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.

Masa pofermentacyjna, jako biodegradowalny odpad biogazowni rolniczej może podlegać zagospodarowaniu bezpośredniemu jako nawóz lub też, po separacji fazy stałej i ciekłej – faza stała może być poddana termochemicznej transformacji do biowęgla. 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.

The present investigation has been carried out on Tagetes erecta to search out the effect of sugar mill effluent on growth and yield. In-vivo conditions were set up for the experiment purpose. Pots were filled with soil and treated with different concentrations of sugar mill effluent i.e., 10, 25, 50, 75 and 100% on morphological parameters of test crop. Results of pot culture experiment showed that at 10 % concentrations of sugar mill effluent proved to better to the crops growth and thereafter the growth may reduce over control. In order to mitigate the effluent toxicity certain Biofertilizers inoculants were mixed to the soil along with the same effluent treatments. The study suggests that the Biofertilizers inoculants along with effluent irrigation proved to be better for plants growth.
