“…[ 34,35 ] Our research group also noticed the significant positive effect on yield in G. max due to the treatment of A. niger . [ 18 ] It is quite conclusive that the increased yield was due to the combined effect of A. niger K7 and pressmud in the current experiment. In another study, it was found that application of pressmud with inorganic fertilizers increased cane yield in red soil.…”

As India is the second‐largest producer of sugarcane in the world, a huge amount of biodegradable by‐product waste, pressmud, is produced every year, and is a promising source of nutrients. Here, an attempt is made to utilize pressmud as carrier for bioinoculants for enhancing crop productivity. The field experiments are set up on finger millet crop using Aspergillus niger (K7) as fungal inoculant and pressmud as carrier. Four treatment combinations, viz., control, K7 strain, pressmud, and K7 strain+pressmud, in soil are studied. The results indicate that the soil nutrients such as N, P, and K increase by 30–50% after the experiment. The pressmud supports up to 5 × 106 fungal spores and the inoculum is viable until the end of 6 months. Growth and yield parameters are influenced positively and result in better height and weight of plants, a higher number of fingers, and improved P uptake. The combination of A. niger (K7) and pressmud is found to be the best. Shoot and root lengths increase by 54% and 96%, respectively, at the time of harvest over control. Number of fingers and weight of grains/plant increase by 77% and 70%, respectively, at 130 days after sowing. It can be concluded that the use of pressmud with microbial inoculant may be an economically viable technology in organic farming and also in its disposal.

“…Biochar provides a suitable habitat for a large and diverse group of soil microorganisms, although the interaction of biochar with soil microorganisms is a complex phenomenon. Many studies reported that addition of biochar along with phosphate solubilizing fungal strains promoted growth and yield of Vigna radiata and Glycine max plants, with better performances than control or those observed when the strains and biochar are used separately [20,79,80].…”

Soil is the most important source and an abode for many nutrients and microflora. Due to rapid depletion of agricultural areas and soil quality by means of ever-increasing population and an excessive addition of chemical fertilizers, a rehabilitated attention is a need of the hour to maintain sustainable approaches in agricultural crop production. Biochar is the solid, carbon-rich material obtained by pyrolysis using different biomasses. It has been widely documented in previous studies that, the crop growth and yield can be increased by using biochar. This chapter exclusively summarizes the properties of biochar, its interaction with soil microflora, and its role in plant growth promotion when added to the soil.

“…For example, Aspergillus niger and Penicillium chrysogenum promote the growth and nutrient uptake of groundnut ( Arachis hypogaea L.) (Jitendra et al, 2011). Inoculation with the PSF Aspergillus niger significantly increases the growth, root nodulation and yield of soybean plants (Saxena et al, 2016). Nevertheless, the effects of PSF on phosphate solubility and growth in forest ecosystems are poorly understood.…”

Microbes in soil can degrade insoluble inorganic and organic phosphorus, which are components of the soil phosphorus cycle and play an important role in plant growth. Pinus massoniana is a pioneer tree species used for afforestation in southern China and grows in poor, acidic soil. A shortage of available phosphorus in soil limits the growth of P. massoniana. To alleviate this situation, it is necessary to improve soil fertility. A fungal strain (JP-NJ2) with the ability to solubilize phosphate was isolated from the P. massoniana rhizosphere. The ability of JP-NJ2 to solubilize inorganic and organic phosphorus and promote the growth of P. massoniana was evaluated. It showed that JP-NJ2 could grow in NBRIP inorganic phosphate (AlPO4, FePO4·4H2O, and Ca3[PO4]2) fermentation broths, with the highest phosphorus concentration (1.93 mg/ml) and phosphate-solubilizing rate (43.7%) for AlPO4 and in Monkina organic phosphate fermentation broth with a phosphorus concentration of 0.153 mg/ml. The phosphate-solubilizing capability in inorganic and organic fermentation broths was negatively correlated with pH. JP-NJ2-produced acids at a total concentration of 4.7 g/l, which included gluconic (2.3 g/l), oxalic (1.1 g/l), lactic (0.7 g/l) and malonic (0.5 g/l) acids. It prioritized extracellular acidic phosphatase and combined with phytase to solubilize organic phosphates. The fungal suspension and extracellular metabolites from phosphate-solubilizing fungi promoted the shoot length of P. massoniana seedlings by 97.7% and 59.5%, respectively, while increasing the root crown diameter by 46.8% and 27.7%. JP-NJ2 was identified as Penicillium guanacastense based on its morphology and phylogenetic analyses of five genes/regions (ITS, ben A, cmd, cox1 and tef). This is the first report on P. guanacastense isolated from pine tree rhizosphere soil in China and its high phosphate-solubilizing capability, which promoted the growth of P. massoniana. P. guanacastense JP-NJ2 has potential use as a biological fertilizer in forestry and farming.
