The depletion of minerals in agricultural soils through subsistence farming has been a major food security challenge in many parts of the world. To curtail this problem, farmers use inorganic fertilizer to boost soil fertility even though it poses a lot of environmental challenges. In this research, an alternative route to soil nutrient amendment was explored via the use of compost and nano-gel water accumulator for blending different soil samples derived from rock side soil and spent farm soils blended in different ratios of 1:0, 1:1, 1:2, and 2:1using a suitable potting media for the greenhouse production of A. spinosus L. Physicochemical values, mineral, and heavy metals concentration were evaluated on the soil and compost samples while mineral, proximate, anti-nutrients and vitamins compositions were analyzed on A. spinosus L. grown on the soils. Data obtained were analyzed using analysis of variance (ANOVA) at a 95% confidence limit using SPSS 20.0 software. The properties of the prepared compost (PC) and commercial compost (CC) varied significantly (P

The present study used chemical fertilizer, brown algae compost and zeolite carried out in the field of Giresun Hazelnut Research Center between May-November 2014 in pots according to randomized blog design as three replicate each. Treatment groups were consist of eight different combinations as follow; G1-Control, G2-Zeolite, G3-Compost, G4-Chemical Fertilizer, G5-Zeolite+Compost, G6-Zeolite+Chemical Fertilizer, G7-Compost+ Chemical Fertilizer, G8-Compost+Zeolite+ Chemical Fertilizer. The brown algae (Cystoseira sp.) were used as compost material. These combinations were applied to green beans (Phaseolus vulgaris). The green beans were seeded by hand to arrange planting depth of 5-6 cm and 20 seeds/m2. Except control group, each treatment was added fertilizers as 50 g zeolite, 50 g compost, and 25 g chemical according to treatment design. Half of the chemical fertilizers were added at seeding time and the rest after two weeks. Collected soil samples were analyzed right after harvest, the greatest values of treatment groups were determined as; Carbon% G1: 5.08, nitrogen G3: 0.09 ppm, sodium G5: 139 ppm, potassium G6 and G8: 5 ppm, magnesium G2: 1865 ppm, calcium G6: 8.33 ppm, manganese G2: 359 ppm, iron G6 : 16070 ppm, cobalt G6 and G7: 7.91 ppm, copper G2: 17.5 ppm, zinc G8: 28.0 ppm, selenium G7: 4.17 ppm, cadmium G5: 0.08 ppm, lead G4: 5.31 ppm. The greatest harvest value as g/m2 was obtained from zeolite only group G2 with 273 while the lowest was obtained from Compost only group G3 with 113 g/m2, obviously showing the effectiveness of zeolite only application moreover, also thinking that better results may get if the present study run for longer period.

It is necessary for developing strategies of integrated fertilization for crops to maximize production of crops and reducing the risk of pollution from chemical fertilizers. Therefore, the objectives of this study to evaluate the impact of bio-organic, chemical nitrogen on seed quality of canola. A study was conducted for two consecutive years (2005 to 2006) at the Farm of Faculty of Agriculture, Kafr El-Sheikh University, Egypt. Bio fertilizer (control and bio-fertilizer), compost (control, 6, 12 and 18 ton ha-1) and chemical nitrogen (control, 36, 72 and 108 kg N ha-1). The result indicated that, bio-fertilizer was significantly effects on protein % and iodine value except oil percent was decreased. On the other hand, the Maximum values oil and protein were recorded by using compost fertilizer at (18 ton ha-1). In respect to chemical fertilizer, adding nitrogen affected significantly on protein % and the maximum value was obtained at (108 N ha-1) while, oil percent and iodine value were decreased. Interestingly, it is clear that from results that cultivar belongs to canola (LEAR that contains < 2% erucic acid) and a nitrogen source has almost slight effect on oil physical properties. Totally, the interaction among treatments application compost (6ton ha-1) and (72 N kg ha-1) with combined bio- fertilizer was achieved suitable oil percent and could be improve canola seed yield and quality and environment would have a better condition.

Recycling plant residues through various processes is essential for addressing waste issues in our country, because it contributes to the protection of the environment and ecosystems. Composting is one of the most important recycling methods for plant residues. Composts are not only natural, but they also enhance soil fertility and exhibit fungitoxic properties on the mycelial and spore germination of fungi. This study aimed to isolate bacterial bioagents from compost derived from various agricultural and household organic wastes, and to assess their antagonistic potential against important plant pathogens Botrytis cinerea and Sclerotinia sclerotiorum under in vitro conditions. A total of eight bacterial isolates were obtained, identified as belonging to Bacillus spp. Dual culture tests were used to evaluate the potential of these bacterial candidates to inhibit the mycelial growth of phytopathogenic fungi. In vitro trials revealed that six bacterial isolates exhibited varying degrees of antagonistic effects (23.3%- 63.3%) on the mycelial growth of B. cinerea. Among the tested bacteria, two isolates were effective against S. sclerotiorum, demonstrating antifungal activity ranging from 80% to 83.3%. The results indicate that composts provide a favorable environment for microorganisms with antagonistic potential, suggesting that these cultivation environments could play a significant role in the biological control of fungal pathogens in agriculture. In conclusion, this study contributes to the development of sustainable agricultural practices by ensuring a more efficient utilization of organic waste.

Most of the dry zone forests in Sri Lanka are arisen after unsustainable farming practices. Therefore, the natural regeneration of plant species in these forests reported to be very poor due to the reduced soil fertility. This study was conducted to find possible measures for the successful seed germination and seedling establishment of common dry zone forest tree species by sustainable soil fertility management. A pot trial was carried out in a greenhouse at the Faculty of Applied Sciences, Rajarata University, Mihintale, Sri Lanka. The experiment comprised of 128 pots and four replicates. Pots were assigned with different soil fertility managements: T0: control (Top soil only), T1: Arbuscular Mycorrhizal Fungi (AMF), T2: a traditional mixed microbial culture (Jeewamurthum), T3: Compost, T4: Biochar, T5: T1+T2, T6: T1+T3, T7: T1+T4; and different forest plant species: Manilkara hexandra, Feronia limonia, Pterospermum conscens and Bauhinia racemosa. Seed germination percentage was measured two weeks after sowing, and shoot biomass, relative plant growth rate, and AMF colonization percentage were measured after four months of germination. The results revealed that inoculation of AMF enhance the seed germination percentage of all the selected plant species. Both sole and combined application of AMF and compost gives more benefits to all the tested plant species by enhancing all the measured growth parameters. The findings of present study would be useful in reforestation programs of dry zone forests in Sri Lanka by practicing sustainable procedures.

Marketplace waste collection is one of the crucial services provided by the district municipalities in Turkey. A significant amount of food waste is periodically collected from marketplaces. However, an important opportunity for recycling and mitigation climate change is missed because these waste are sent to landfills. Composting, one of the waste management technologies applied to organic waste to reduce greenhouse gas emissions and produce compost, is often preferred for the management of marketplace waste. This study aims to determine suitable locations for compost facilities to manage marketplace waste with the help of GIS considering economic, environmental, and topographic factors in Izmir, Turkey. There are 199 marketplaces in Izmir and each has at least one market a week. Each marketplace was weighted by means of population served by using location-allocation analysis since the amount of waste collected from the marketplaces is not known. First, an exclusion analysis was performed to remove limited use areas. Then, a preference analysis was performed. Factors affecting plant site selection process for composting marketplace waste, including marketplace locations and weights, were determined. Since all factors do not have equal importance, the analytical hierarchy process was used to determine weights for each factor based on their influence. The study area was spatially evaluated for each preference factor and a suitability map was created for each factor. Finally, a high-resolution final suitability map was obtained by combining each factor’s suitability map along with their weights. Areas with a suitability index greater than 80% have been defined as suitable areas for compost facility installation. The results indicate that there are 323 potential locations suitable for compost facilities in Izmir.
