In this experiment, 8-year-old yellow fruit citrus trees were used as materials, and the soil nutrients were determined with the combination of Bacillus megaterium, glial bacillus, organic-inorganic compound fertilizer and organic fertilizer, and the conventional application of organic fertilizer as the control. The results showed that the soil nutrients of the treatments of Bacillus megaterium, Bacillus glia and organic fertilizer were significantly higher than those of the control. The treatment of applying Bacillus megaterium and Bacillus glia alone reached a significant level in many soil nutrient indexes. It is suggested that the combination of Bacillus megaterium, Bacillus glia and organic fertilizer should be applied in production.

Trichoderma spp. are proposed as major plant growth-promoting fungi that widely exist in the natural environment. These strains have the abilities of rapid growth and reproduction and efficient transformation of soil nutrients. Moreover, they can change the plant rhizosphere soil environment and promote plant growth. Pinus sylvestris var. mongolica has the characteristics of strong drought resistance and fast growth and plays an important role in ecological construction and environmental restoration. The effects on the growth of annual seedlings, root structure, rhizosphere soil nutrients, enzyme activity, and fungal community structure of P. sylvestris var. mongolica were studied after inoculation with Trichoderma harzianum E15 and Trichoderma virens ZT05, separately. The results showed that after inoculation with T. harzianum E15 and T. virens ZT05, seedling biomass, root structure index, soil nutrients, and soil enzyme activity were significantly increased compared with the control (p < 0.05). There were significant differences in the effects of T. harzianum E15 and T. virens ZT05 inoculation on the growth and rhizosphere soil nutrient of P. sylvestris var. mongolica (p < 0.05). For the E15 treatment, the seedling height, ground diameter, and total biomass of seedlings were higher than that those of the ZT05 treatment, and the rhizosphere soil nutrient content and enzyme activity of the ZT05 treatment were higher than that of the E15 treatment. The results of alpha and beta diversity analyses showed that the fungi community structure of rhizosphere soil was significantly different (p < 0.05) among the three treatments (inoculated with T. harzianum E15, T. virens ZT05, and not inoculated with Trichoderma). Overall, Trichoderma inoculation was correlated with the change of rhizosphere soil nutrient content.

The low quality of Entisol is caused by low availability of nitrogen, phosphorus, and potassium as well as low soil pH, so the addition of vermicompost is necessary. The purpose of this study was to determine the effect of vermicompost application on soil quality and to obtain the highest vermicompost dosage on the availability of nutrients such as N, P, K, and the yield of corn. The field experiment used a Randomized Completely Block Design (RCBD) with 7 dosages of vermicompost and three replications. The treatments were V0 = 0; V1 = 5; V2 = 10; V3 = 15; V4 = 20; V5 = 25; V6 = 30 Mg ha-1. Variables observed consisted of 1) initial soil and vermicompost characterization analysis, 2) soil analysis and N, P, and K content in leaves, and yield of corn. The results showed that Entisol was classified as low quality; however, vermicompost quality complied with the requirements of quality organic fertilizer. The experiment also indicated that the highest pH of Entisol (5.31) and K content in corn leaves (2.12%) were obtained at a dose of vermicompost 25 Mg ha-1. Meanwhile, the highest weight of husked corn cobs (415.55 g plant-1) and weight of unhusked corn cob (351.11 g plant-1) were obtained at a vermicompost dose of 15 Mg ha-1.

The rapidly emerging fertilizer rapeseed used as green manure has wide applications for use. However, there have been few studies on its decomposition and effects on soil nutrients and microorganisms after its decay. In this study, 12 rapeseed lines to be screened were decomposed through a randomized block field design with two green-manure-specific varieties as the controls. The contents of nitrogen, phosphorus, and potassium from the plants, soil nutrients, and microbial changes after degradation were measured. There were substantial differences in the rates of decomposition and cumulative release of nutrients among the different lines after 30 days of rolling. The contents of phosphorus and potassium in the soil were 1.23–2.03 and 3.93–6.32 times those before decomposition, respectively. In addition, there was a significant difference in the relative content of soil microorganisms at the phylum level after the decomposition of different species of rapeseeds. Most of the top 20 bacterial groups significantly correlated with the characteristics of plant decomposition and soil nutrient content, including Proteobacteria, Actinomycetes, Armatimonadetes, Rokubacteria, and Planctomycetes. A principal component analysis showed that the soil microorganisms and nutrients are the leading factors that enable the evaluation of the decomposing characteristics of green manure rapeseed. Numbers 5 (purple leaf mustard) and 8 (Xiafang self-seeding) were more effective than two controls, which can be used as excellent types of germplasm to promote the breeding of green manure rapeseed.

Micro small business (UKM: in indonesian) "Sejahtera" is a chicken farm that has problems with chicken manure that has not been utilized properly. The farmer group "Bejo Agro Farm" is a plant nursery located in Mojogedang District, Karanganyar Regency. Availability of soil nutrients is one of the determinant factors of the quality of plant seeds. Availability of nutrients for plants can be obtained by applying organic fertilizers. Applications of microbial enriched organic fertilizers can be used as an alternative to maintain plant quality. Microbial enriched organic fertilizers contain several types of microbes that can support plant growth. Organic fertilizer comes from chicken manure coupled with several bio-starter containing beneficial microbes. The organic fertilizer used has been tested for its quality, to determine the content of the nutrient. The technology in the form of microbial enriched organic fertilizer can help "Bejo Agro Farm" to maintain the quality of plant seeds and be able to solve the problems of chicken manure waste of "Sejahtera" chicken farms.

Decline disease causes severe damage to bayberry. However, the cause of this disease remains unclear. Interestingly, our previous studies found that the disease severity is related with the level of soil fertilizer. This study aims to explore the effect and mechanism of compound fertilizer (CF) and bio-organic fertilizer (OF) in this disease by investigating the vegetative growth, fruit characters, soil property, rhizosphere microflora and metabolites. Results indicated that compared with the disease control, CF and OF exhibited differential effect in plant healthy and soil quality, together with the increase in relative abundance of Burkholderia and Mortierella, and the reduction in that of Rhizomicrobium and Acidibacter, Trichoderma, and Cladophialophora reduced. The relative abundance of Geminibasidium were increased by CF (251.79%) but reduced by OF (13.99%). In general, the composition of bacterial and fungal communities in rhizosphere soil was affected significantly at genus level by exchangeable calcium, available phosphorus, and exchangeable magnesium, while the former two variables had a greater influence in bacterial communities than fungal communities. Analysis of GC-MS metabonomics indicated that compared to the disease control, CF and OF significantly changed the contents of 31 and 45 metabolites, respectively, while both fertilizers changed C5-branched dibasic acid, galactose, and pyrimidine metabolic pathway. Furthermore, a significant correlation was observed at the phylum, order and genus levels between microbial groups and secondary metabolites of bayberry rhizosphere soil. In summary, the results provide a new way for rejuvenation of this diseased bayberry trees.

This research aims to know the effect interaction of application of types and different dosage of organic fertilizers on production and fruit quality of melons on peatlands, effect of application of types and different dosage of organic fertilizers on production and fruit quality of melons on peatlands, and the agronomic efficiency of the use of several types and different dosage of organic fertilizers on production of melons on peatlands. This research design was used as a Randomized Block Design (RBD) consists of two factors with 4 replication. The first factor consisted of types of organic fertilizer (P) i.e. chicken manure (PA), guano manure (PG), and cow manure (PS). The second factor consisted of fertilizer dosage (D) i.e. 0 tons ha-1 (without fertilization, called control), D1 = 15 tons ha-1, D2 = 30 tons ha-1 and D3 = 45 tons ha-1. The data obtained by analysis of variance (ANOVA) or F test at a = 5% and 1% levels to determine the effect of treatment was tested further by HSD (honestly significant difference) testat the level of 5%. The result shows that the interaction type of organic fertilizer and the dosage of organic fertilizer treatment significant effect on the weight of the melon. Chicken manure is the best organic fertilizer on the size and quality of the melon. Dosage of 45 tons ha-1 organic fertilizer gave the highest results but it was not significantly different with a dosage of 30 tons ha-1. The use of chicken manure fertilizer of 30 tons ha-1 is more efficient in agronomy in increasing melons yield on peatlands.
