“…Once absorbed by the roots, nitrates are transferred to the shoots where they are reduced to ammonium and used to first synthesize glutamate and glutamine through the enzymatic nitroreductase and GOGAT systems, and then other amino acids and Ncontaining compounds. The total N concentration values are consistent with those reported in literature for spinach leaves (22.7-51.5 g kg −1 ) [15,27]. The low nitrogen concentration found in the plants grown on the BP-added substrate (trial 6) suggests that BP is recalcitrant to the biochemical attack by microorganisms, in accordance with the high lignin-like chemical moieties present in its macromolecular structure [4].…”

“…The data obtained from the present experiment show significant differences only between trials 2, 3, and 6 for the leaf fresh biomass, but not the dry one (Table 2). The average dry weight of the leaves (2.2 g per plant) is consistent with literature data for cultivated spinach under different conditions: 0.6-2.0 g per plant for hydroponic cultures [15,25], 0.2-1.2 g per plant in pot experiments, depending on the amount of added nitrogen [26], and 4.3-5.4 g per plant in trials where different composts were used as fertilizers [27].…”

This work addresses environmental problems connected with biowaste management, the chemical industry, and agriculture. These sectors of human activity cause greenhouse gas (GHG) emissions in the air, climate change, leaching of excess mineral fertilizers applied to soil into ground water, and eutrophication. To mitigate this problem in agriculture, controlled release fertilizers (CRFs) are made by coating mineral fertilizers granules with synthetic polymers produced from the fossil-based chemical industry. This strategy aggravates GHG emission. In the present work, six formulations containing sunflower protein concentrate (SPC) and a new biopolymer (BP) obtained from sunflower oil cake and by hydrolysis of municipal biowaste, respectively, and commercial urea were tested as CRFs for spinach cultivation against the control growing substrate Evergreen TS and commercial Osmocote®. The results show large differences in plants’ nitrate concentration due to the different treatments, although the same nitrogen amount is added to the substrate in all trials. BP is the key component mitigating nitrate accumulation in plants. The plants grown in the substrates containing BP together with SPC and/or urea, although exhibiting relatively high total N uptake (47–52 g kg−1), have significantly lower nitric to total N ratio (9.6–12.0) than that (15.3–16.5) shown by the plants grown in the substrates containing SPC and/or urea, but no BP. The data confirm that all composites containing BP yield the safest crop coupled with high biomass production. Replication of BP effects for the cultivation of different plants will contribute to the development of a biobased chemical industry exploiting biowastes as feedstock.

“…The use of fresh spent coffee grounds can be toxic to plants 42 , therefore, it is proposed to compost them or treat them using another method 43 . This study showed that mixing spent coffee grounds with chicken and duck eggshells and incubating them for 3 months can give an organic-calcium fertiliser valuable to plants 39 , 44 , and such a mixture can also be a good soil improver.…”

Spent coffee grounds (SCG) as well as chicken (CES) or duck eggshells (DES) left over from the artificial hatching technology are proposed as potential soil improver and/or organic-mineral fertiliser components. Therefore, it seems interesting and necessary to evaluate the chemical composition of these wastes and their mixtures in terms of their possible use for that purpose. The study was conducted under the incubation experiment conditions using a mixture of SCG and eggshells (10:1 ratio). Macronutrients, i.e. C, N, S, were determined by the catalytic combustion method, while P, K, Mg, Ca, Na by atomic spectrometry. It was found that SCG were rich in C, N, P, and K, while eggshells in Ca, Mg, Na, and S. However, CES compared to DES were richer in deacidifying components (i.e. Ca, Mg, K). At the same time, the content of macronutrients in eggshells decreased gradually along with the embryo development. For this reason, the mixture of SCG and shells of unembryonated chicken eggs (CES I) had the best chemical and usable proprieties. To conclude, the chemical properties of the mixtures of spent coffee grounds and eggshells indicate their possible application in soil bioengineering.

“…The beneficial effect of compost tea on herb dry matter may be due to both supply nutrients and microbial functions (as useful microorganisms increase the time stomata stay open, then reducing loss from the leaf surface). It can provide chelated microelements and make them easier for plants to absorb and increasing soil aeration and acidity (Ebid et al, 2008). This decrease of compost tea applied as soil application on onion growth due to soil components (i.e., organic matter, Al-and Fe-hydr oxides, variable charge clays, ect.…”

A field experiment was carried out at the Experimental Farm of Sakha Agricultural Research Station in Kafr El-Sheikh Governorate at North Nile Delta Region. The experiments were conducted to study the response of onion to nitrogen fertilizer levels under different bio-organic fertilizers (compost tea and N2-fixing bacteria) as well as their interaction, on some soil properties and the growth and onion bulbs yield and its quality during the two successive winter seasons of 2009/2010 and 2010/2011. A split-split plot design with three replicates was used in this study. The main plots were designated to the three mineral nitrogen fertilizer levels (60, 90 and 120 kg N fad.-1), whereas foliar spraying treatments with compost tea at the same dose, 20 L fad.-1 (spraying with water; foliar spraying at 40 days after transplanting (DAT); foliar spraying at 40 and 60 DAT; foliar spraying at 40, 60 and 80 DAT and soil application, 30 DAT at rate of 30 L fad.-1) were randomly distributed in sub plots. While uninoculation and inoculation with di-nitrogen fixing bacteria (Azotobacter Chroococum and Azospirilium Brasilense) were randomly distributed in the sub-sub plots. The obtained results could be summarized as follow: The highest increase in soil available nutrients (N, P and K), organic matter percentages and total bacterial counts were increased significantly and recorded in the plots treated with compost tea as soil application batches and/or inoculation at nitrogen fertilizers level 90 kg N fed-1 (N2B4C2) while the lowest were recorded in the uninoculated plots treated with N fertilizers at 60 kg N fed-1 without both compost tea and bacterial inoculation. With inoculation and mineral nitrogen applications, soil salinity and pH were decreased in compost tea treatment under soil application as compared with others compost tea applications. The experimental results confirmed that the combination of compost tea, inoculation by di-nitrogen fixing bacteria and mineral nitrogen fertilizers could improve soil fertility. Growth and onion bulbs yield and their quality were highest due to application of compost tea on thrice than twice batches at the same dose and other treatments. The effect of bio-fertilizer in plant height, leaves dry weight/plant, bulb dry weight, plant dry weight, bulb diameter and bulb weight as well as bulb quality was evident in both seasons. In general, inoculation with Azotobacter chroococcum and Azospirilium brasilense positively increased all the previous characters. Based on the results of the current study, the combinations of medium dose of mineral N and compost tea or biofertilizers could be considered as an integrated nutrient management to improve soil bio-physical properties and the growth and yield of onion plants. It also confirmed that compost tea can be used as organic substrate additives in plant cultivation and substitute for chemical nitrogen fertilizers.
