“…In addition, specific enzyme activity can also serve as a functional indicator with direct ecological impacts and, therefore, can be more easily used as an indicator of changes in the composition of the soil microbial community. In comparison to the absolute enzyme activity, specific enzymatic activity can be used to normalize the differences in MBC in the different treatments and is a more accurate measure for comparing the extent to which different treatments affect the functioning of the soil microbial community (LIU et al, 2017).…”

Microbial Biomass and Enzymatic Activities in Sandy Soil Cultivated With Lettuce Inoculated With Plant Growth Promoters

et al. 2018

Plant growth promoter microorganisms have been studied as important tools for increasing crop production. Lettuce is the most consumed hardwood crop in the world. Numerous microorganisms are capable of acting in a beneficial way in the growth of this culture. The objective of the present study was to evaluate the efficacy of Trichoderma and Pseudomonas on the microbial biomass, enzymatic activities in sandy soil and lettuce production. The experimental design was completely randomized with ten replicates and treatments: CONT (absolute control); CM (control with cattle manure fertilization); CMB (with fertilization and Pseudomonas sp.); CMF (with fertilization and T. aureoviride) and CMBF (with fertilization and the two microorganisms combined). The fertilizer used was organic with cattle manure in a dose recommended for the culture. This study evaluated the production of lettuce, microbial biomass and the enzymatic activity of acid phosphatase, alkaline phosphatase and urease. The combined application of CMBF was efficient in increasing lettuce production, because it increased 85% of the cv. Veronica cultivated on sandy soil. The combined use of plant growth promoting microorganisms resulted to an increase in microbial biomass. In lettuce crops, it is recommended to use T. aureoviride URM 5158 and Pseudomonas sp. UAGF 14 in lettuce crops, because improved lettuce production, improves the biochemical quality of soils measured by absolute and specific enzymatic activities per unit of microbial biomass.

“…Biochar with a high mineral content and surface area can be used to condition soil by recycling the minerals back to soil and increasing the soil holding capacity of water and nutrients, and thus increasing the sustainability of the farming system [25]. Moreover, recent developments in activation procedures allow a better control over the pore structure and surface property, which have widened the use of biochar to more demanding applications including catalyst precursor, energy storage, gas storage, and contaminant adsorbents [26,27].…”

Hydrothermal Liquefaction Enhanced by Various Chemicals as a Means of Sustainable Dairy Manure Treatment

et al. 2018

Abstract:Because of the increase in concentrated animal feeding operations, there is a growing interest in sustainable manure management. In this study, hydrothermal liquefaction (HTL) of dairy manure enhanced by various chemicals (NH 3 ·H 2 O, H 3 PO 4 , and glycerol) was proposed as a sustainable alternative for the dairy manure management. The applications of NH 3 ·H 2 O and H 3 PO 4 during HTL could significantly enhance the production of liquid chemicals. The addition of NH 3 ·H 2 O or glycerol increased the amounts of non-polar toluene, xylene, and other benzene-contained compounds, while the use of H 3 PO 4 produced high amounts of acids, pyridine, 3-methyl-pyridine, 2,6-dimethyl-pyrazine, 2-cyclopenten-1-ones, and phenols. The biochars produced via HTL showed a significant increase in the surface area/pore volume and relatively higher N, P, C, and other minerals, and may serve as a good soil amendment and nutrient source. The preliminary energy analyses showed that the energy consumption of this process might be reduced to 50% of the original energy content of the feedstock, and the energy payback period was about 3.5 years. Combining all advantages, HTL of dairy manure might increase the sustainability of the farming operation via producing energy products, fine chemicals, and biochars.

“…Hal tersebut menunjukkan bahwa arang hayati pada dosis tertentu berpotensi meningkatkan ketersediaan P dalam tanah melalui perannya dalam mendukung perkembangan MPF yang mempunyai kemampuan melarutkan senyawa P anorganik kurang larut. Liu et al (2017) melaporkan bahwa pemberian arang hayati meningkatkan kelimpahan dan distribusi Thiobacillus, Pseudomonas, dan Flavobacterium, kelompok bakteri pelarut fosfat dalam tanah. Menurut Siddiqui et al (2016), aplikasi arang hayati dan MPF secara terintegrasi merupakan strategi untuk meningkatkan aktivitas MPF dalam memobilisasi P lebih tinggi pada tanah sehingga mendukung pertumbuhan dan produktivitas tanaman menjadi lebih baik.…”
