“…Ayrıca, kurutulan (40°C ve 60°C) ve tekrar nemlendirilen topraklardaki kısa dönemli karbon mineralizasyonunun (1-3 günlük), uzun dönemli (100 günlük) CO2 oluşumu ve toprak mikrobiyal biyokütle karbonu ile önemli bir biçimde korelasyon gösterdiği ifade edilmiştir [42,43]. Toprakta inkübasyon süresince mineralize olan karbonunun toprak organik karbonuna olan oranına " Karbon mineralizasyon oranı" denilmektedir [39,40,44]…”

Tarımsal ekosistemlerde yabancı otların kontrolünde en çok tercih edilen yöntemlerden birisi herbisit kullanımıdır. Mikrobiyal aktive toprakta herbisitlerin davranışlarını belirleyen en önemli faktörlerdendir. Karbon mineralizasyonu toprak kalitesinin biyolojik indikatörlerinden olup topraktaki tüm canlıların hayati faaliyetlerini sürdürebilme kapasitesini yansıtmaktadır. Bu derlemede tarım alanlarında yabancı ot kontrolünde en fazla kullanılan bileşikler olan atrazine ve glyphosate'ın toprakta karbon mineralizasyonuna olan etkileri özetlenmiştir.

“…Because of their bactericidal properties, silver nanoparticles (AgNP) are present in numerous consumer products. During recent years, an increasing number of studies have demonstrated toxicity of AgNP to different microorganisms such as bacteria − or algae. − The toxicity of AgNP to microorganisms has been suggested to result from both the release of silver ions (Ag + ) and interactions between AgNP and cell membrane. ,− The determining role of Ag + in explaining the observed toxicity of AgNP to microorganisms is experimentally supported by the fact that complexation of Ag + by thiol ligands, as well as anaerobic conditions, prevents toxicity of AgNP. ,,− Thus, risk assessments of AgNP need careful consideration of the contribution of Ag + to toxicity. Ionic silver might occur in AgNP suspensions, both as residual from particle synthesis and formed upon particle oxidation.…”

Various factors have been invoked to explain the toxicity of silver nanoparticles (AgNP) to microorganisms including particle size and the nature of stabilizing coatings as well as the amount of dissolved silver occurring in AgNP suspensions. In this study we have assessed the effects of nine differently coated AgNP (chitosan, lactate, polyvinylpyrrolidone, polyethelene glycol, gelatin, sodium dodecylbenzenesulfonate, citrate, dexpanthenol, and carbonate) and AgNO3 on the photosynthesis of the freshwater algae Chlamydomonas reinhardtii. We have thus examined how AgNP effects on algae relate to particle size, measured dissolved silver (Agd), and bioavailable silver (Agbioav). Agbioav was indirectly estimated in toxicity experiments by cysteine-silver complexation at the EC50. The EC50 calculated as a function of measured Agd concentrations showed for some coatings values similar to that of dissolved Ag, whereas other coated AgNP displayed lower EC50 values. In all cases, excess cysteine completely prevented effects on photosynthetic yield, confirming the role of Agd as a cause of the observed effect on the photosynthesis. Toxicity was related neither to particle size nor to the coatings. For all differently coated AgNP suspensions, the EC50 values calculated as a function of Agbioav were comparable to the value of AgNO3. Depending on the coatings Agbioav was comparable to or higher than measured Agd.

“…Therefore, it was reported that this strong connection between glyphosate and these compounds decreased the bioavailability of glyphosate for microorganisms [35]. It was reported that applications of recommended field dose and its 2 and 4 folds of imazamox (a herbicide) showed similarities with control in ammonium contents while increasing doses of imazamox decreased soil nitrate production [32]. Authors in the same research indicated that nitrate producing bacteria in soils were sensitive to addition of imazamox into soil [32].…”

“…As a result, when any environmental change like the application of herbicides for weed control occurred, this can affect soil carbon cycling by altering metabolic activity and community structure [22]. It was reported that soil microorganisms that were not affected by different soil moistures could use imazamox (a herbicide) as both carbon and nitrogen source and recommended field dose and its 2 fold dose of this herbicide were found similar with control in soil carbon mineralization [32]. In another study, it was noted that recommended field dose, its 2 and 4 folds of another herbicide named glyphosate-amine salt had no negative or positive effect on soil carbon mineralization compared to its non-herbicide exposed soil [33].…”

Indaziflam is a herbicide used for weed control in vineyards, apple, peach and orange orchards that inhibit cellulose biosynthesis in plants. The objective of this study was to evaluate the effects of recommended field dose of herbicide Indaziflam (10 ml/ da, RD) and its 2 (RD x2), 4 (RD x4), 8 (RD x8) and 16 (RD x16) folds of RD on carbon and nitrogen mineralizations in a vineyard soil. Herbicide+soil mixtures were humidified at 80% of soil field capacity and then incubated for 42 days at 28ºC. Effects of RD and RD x2 doses on soil carbon mineralization were similar to control and no significant difference was found between them. Higher doses of indaziflam (RD x4, RD x8 and RD x16) stimulated mineralization of soil carbon and there were found significant differences between control and these doses (P<0.05). All application doses of herbicide showed variability in ammonium (NH4-N) and nitrate (NO3-N) contents while there were generally found no significant differences between control and RD. In general, contents of soil NH4-N and NO3-N were increased in all applications as time passed and there were significant differences between days that were measured of these contents (P<0.05). Results of soil nitrogen mineralization rate were as following: 1) It was significantly decreased by only RD x2 on 11 th day (P<0.05) 2) Higher doses of Indaziflam (RD x4, RD x8 and RD x16) significantly stimulated it on 26 th day (P<0.05) 3) All doses of this herbicide significantly decreased it on 42 nd day (P<0.05). In conclusion, the recommended field dose of Indaziflam had no negative effect on microorganisms that play an active role in soil carbon and nitrogen mineralization.
