“…This result suggests the change in microbial community composition could be primarily due to PM application. Similar results were previously reported in soil amended with compost (Baker et al 2011;Eo and Park 2013). The effect of PM on soil microbial PLFA may be attributed to PM as metabolic substrates, which changes the growth conditions of microorganism and subsequently changed the concentration of PLFA (Hill et al 1993;Zelles 1999).…”

This study aimed to evaluate the effects of poultry manure (PM) on soil biological properties in DBP- and DEHP-contaminated soils. An indoor incubation experiment was conducted. Soil microbial biomass C (Cmic), soil enzymatic activities, and microbial phospholipid fatty acid (PLFA) concentrations were measured during incubation period. The results indicated that except alkaline phosphatase activity, DBP and DEHP had negative effects on Cmic, dehydrogenase, urease, protease activities, and contents of total PLFA. However, 5 % PM treatment alleviated the negative effects of PAEs on the above biochemical parameters. In DBP-contaminated soil, 5 % PM amendment even resulted in dehydroenase activity and Cmic content increasing by 17.8 and 11.8 % on the day 15 of incubation, respectively. During the incubation periods, the total PLFA contents decreased maximumly by 17.2 and 11.6 % in DBP- and DEHP-contaminated soils without PM amendments, respectively. Compared with those in uncontaminated soil, the total PLFA contents increased slightly and the value of bacPLFA/fugalPLFA increased significantly in PAE-contaminated soils with 5 % PM amendment. Nevertheless, in both contaminated soils, the effects of 5 % PM amendment on the biochemical parameters were not observed with 10 % PM amendment. In 10 % PM-amended soils, DBP and DEHP had little effect on Cmic, soil enzymatic activities, and microbial community composition. At the end of incubation, the effects of PAEs on these parameters disappeared, irrespective of PM amendment. The application of PM ameliorated the negative effect of PAEs on soil biological environment. However, further work is needed to study the effect of PM on soil microbial gene expression in order to explain the change mechanisms of soil biological properties.

“…Plants grown at high rates of 4N-0.9P-1.7K and 3N-1.3P-2.5K fertilizers showed symptoms associated with excessive fertilization. In addition, Eo and Park (2013) reported that the application of manure composts may accelerate root rot disease by promoting pathogenic fungi. In practice, growers need to be cautious with organic fertilizer application rates.…”

Fertility management of seedlings and transplants is considered a key challenge in organic greenhouse production. This study was conducted to determine response of greenhouse-grown cucumber (Cucumis sativus) and nutrient release profile to two organic fertilizers and their combinations applied at three different concentrations in organic substrate. The organic fertilizers used were a turkey litter–based compost (TC) and a dairy manure vermicompost (VC). In addition, two control treatments [no fertilization (CK), conventional liquid fertilizer (CF)] were included. For TC, substrate leachate pH decreased for the first 17 days after addition and then increased, whereas electrical conductivity (EC), and calcium (Ca) and nitrate-nitrogen (NO3−-N) concentrations increased and then declined. For VC, EC decreased continuously over time from days 0 to 52, whereas pH increased. The Ca and NO3−-N concentrations decreased over time to 24 days and then did not change further. For TC/VC combinations, EC was stable for the first 17 days and then declined. For all organic fertilizer applications, potassium concentration was stable for the first 17 days and then decreased, whereas most of the sodium, ammonium-nitrogen, and chloride were no longer leached by 24 days. The VC and TC/VC combinations did not affect cucumber seed germination rate, seedling survival rate, seedling height, and leaf greenness (SPAD) as compared with CF. The stem length, leaf number, dry weight (DW), root index, and SPAD readings of cucumber transplants increased with increasing TC and VC fertilizer applications. The TC/VC combinations increased the biomass of cucumber transplants compared with CK, and did not differ from CF. The results of this study indicated that the 28.32 lb/yard3 of VC (high rate) or the 9.44 lb/yard3 of VC combined with 4 lb/yard3 of TC (medium rate) can be substituted for CF for the cultivation of cucumber seedlings. Based on DW, the 12 lb/yard3 of TC (high rate) or the 4 lb/yard3 of TC combined with 9.44 lb/yard3 of VC (medium rate) fertilizers were suitable replacements for CF for the cultivation of cucumber transplants.

“…Cultivation site is also a critical factor determining local climate and topology. Fertilization is beneficial in crop production, and farmers apply various organic materials in the cultivation of P. ginseng (Eo and Park 2013). It is thus desirable to determine the influence of various soil nutrient conditions on ginseng culture.…”

We aimed to evaluate the effects of abiotic factors on root growth and ginsenoside content of Panax ginseng and on the tradeoff between these two properties. Three experiments tested the effects of fertilization, soil particle size and cultivation site, respectively, on root growth and ginsenoside content. Moderate applications of nitrogen, phosphorus, and potassium did not significantly influence ginsenoside content. Root weight was negatively correlated with ginsenosides Rg1 and Rg2 with excessive fertilization, suggesting that environmental stress caused by excessive fertilization might have created a tradeoff. We tested the effect of soil type by separating soil out according to particle size (ie, < 0.5, 0.5-1 and 1-2 mm, and a mixed control). Root weight was lower in soil of < 0.5 mm, and roots were longer in soil of 1-2 mm compared with those of the control. Total ginsenoside and ginsenoside Rb 1 content was lower in soil of < 0.5 mm than those of the unsieved control. These results indicate that soil texture is an important factor determining ginsenoside yield and root quality. The effect of cultivation site was compared among 5 locations using the same soil type. There was a 2.8-fold difference in root weight and a 2.1-fold difference in total ginsenoside content between the highest and lowest values among 5 sites, and no significant correlation was found between root growth and ginsenoside content. Our results suggest that ginsenoside content was influenced by abiotic stresses caused by changes in nutrient, moisture, and temperature. We conclude that proper management of abiotic stresses can promote both root growth and ginsenoside content without a tradeoff between these two properties.
