“…The treatment CL0 which was composed of only the mineral fertilizer (NPK) provided more grain per spike with an average of 36.0 compared to CL2 of 33.6 which is constituted by a proportional mixture of the mineral fertilizer (NPK) 50% + manure organic + biofertilizer. This was explained by the slow and gradual release of the elements contained in the dose CL2 compared to CL0 the findings supported by the results of [20,26].…”

“…Moreover, the excess input of chemical fertilizers resulted in NO 3 leaching, volatilization of NH 3 , and NO x emission from agricultural fields and damaged both environment and human health [3,5,6,18,19]. Efforts have been devoted to reduce chemical fertilizers application in wheat production, and organic manure and biofertilizers amendments are considered to be feasible ways to realize this goal without decreasing grain yields [11,[20][21][22]. Application of organic manure can increase soil carbon, improve soil fertility, and obtain similar yield compared with inorganic fertilizer addition [18,23,24].…”

Contrasting Impacts of Long-Term Application of Biofertilizers and Organic Manure on Grain Yield of Winter Wheat in North China Plain

et al. 2019

The effects of long-term incorporation of organic manure and biofertilizers have been investigated on winter wheat in the North China Plain (NCP). The five-year field experiment (2013–2018) has illustrated the responses of grain yield and yield components. Seven fertilization approaches, included pig farm-yard-manure and biofertilizers amendments combined with five NPK% drop levels of chemical fertilizer ratio + organic fertilizer + biofertilizer (0, C+O+B) 25%, CL4; 50%, CL3; 75%, CL1; and 100%, CL0), without fertilizer as control (CK), in NCP during the years 2013–2018. Results showed that the grain yields of CL1 and CL2 were equivalent to CL0 in all growing seasons except 2014/2015. The grain yields of CL4 were 29.9% to 46.6% lower than that of CL0 during 2014/2015, 2016/2017, and 2017/2018. The valuable spike-number, grain number per-spike, and 1000-grain weight showed significant variations among different growing periods. Regression analysis of grain yield and yield components indicated that number grains per-spike showed significant increase in seed yield formation. The 1000-grain weight was the major parameter that influenced yield of moderate and low yielding periods, respectively. The results revealed that application of 30 m3 ha−1 pig farm-yard-manure and 20 kg ha−1 biofertilizers has reduced at least 50% of the NPK fertilization without dropping grain yields in the North China Plain.

“…Zabihi et al [22] demonstrated the possibility to reduce up to 50% of fertilizer application without crop yield reduction under controlled conditions. Unfortunately, results are contrasting between greenhouse and field experiments possibly due to plant-soil interaction knowledge gaps, differences between plant and soil types, and incorrect microorganism strain selection [23].…”

Phosphorus Microbial Solubilization as a Key for Phosphorus Recycling in Agriculture

Phosphorus - Recovery and Recycling

The chapter describes the phenomenon of microbial solubilization carried out both by bacteria and fungi in the natural environment. The mechanism of dissolving phosphorus compounds by microorganisms, the importance of phosphorus solubilization for its accessibility to plants, as well as the possibility of using microbial solubilization in the process of valorization of secondary raw materials were discussed in this chapter. It was underlined that by using the biofertilizers, we can be able to reduce the amount of artificial fertilizer needed for cropping. Moreover, few models were mentioned to describe this phenomenon to express the changes observed during the solubilization process.

This study was conducted with the aim of isolating and identifying endophytic bacteria associated with bananas in Kenya and assessing their functional potentiality as biological fertilizers. Banana material was collected from two different banana cultivars in five different geographical regions and bacteria were isolated using five different isolation media. Whole-cell matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF/MS) analysis was used for microorganism profiling. Protein from the living cells were extracted using the ethanol/formic acid extraction procedure and intact molecular weights of the ionized proteins directly measured and the pattern of the protein molecular weights used as fingerprints. Forty three isolates were selected for partial 16S rRNA gene sequencing. Isolates were characterized on the basis of their in-vitro plant growth-promoting activities that included abilities to fix free nitrogen, solubilize phosphates and produce siderophores. The isolates were identified as Serratia,
