“…In addition, attempts have been made to reduce gaseous emissions through the use of acidic materials other than alkaline and neutral materials like water [10,22]. Although some acidic materials used in composting have been found to be effective in reducing emissions, most tend to compete with microorganisms that are involved in the decomposition process, thereby rendering them inactive and ensuring their death [22,23]. Moreover, the materials that are used in pile acidification are expensive and often not employed under resource-poor conditions.…”

This study investigated the altering effect of moisture on the emission pattern of gases and the evolutionary dynamics of physicochemical indices in corn straw and cow manure composting. Exploring this effect was reasonable to unravel the use of moisture as a cheap alternative to control gaseous emissions and improve the final properties of compost. The nutrient dynamics of the compost showed 21.6% losses in total organic carbon content, with a 33.3% increase in total nitrogen content at the end of composting. All the gases (CH4, CO2, N2O and NH3) yielded a common emission pattern despite the differences in moisture content. Except for CH4, the peak and stable emission periods of all the gases were observed on the 5th day (thermophilic phase) and after the 27th day (late mesophilic phase) of composting, respectively. Emission reductions of 89%, 91%, 95% and 100% were recorded for CH4, CO2, N2O and NH3, respectively, during the late mesophilic phase of composting. From the study, the 65% moisture content was efficient in reducing the loss rate of the gasses and nutrient contents of the compost. This study would enable farmers to channel organic residues generated into compost while minimizing pollution and nutrient losses associated with the composting process.

“…The floor of each pit was covered with polyethylene sheet to reduce seepage of nutrients during composting. FYM were added with 0, 2 and 4 % P from rock phosphate (RP) and triple calcium super phosphate (TSP) on dry weight basis (Wu et al, 2019;Luo et al, 2013). The P sources were spread over composting materials in difference layers.…”

Phosphorus is placed as second essential nutrient for plant growth. It builds 0.2 % of plant dry matter as constituent of nucleic acids (e.g DNA and RNA), phospholipids (in cell wall) and ATPs as energy car-Abstract | Pretreatment of organic materials with phosphatic fertilizers can alter P fractionations in soil and boost up its availability to plant in calcareous soils. For this purpose, a pot experiment was conducted in the green house of the University of Agriculture Peshawar to assess changes in P fractionations and wheat seedlings growth in two diverse calcareous soils. The pretreated composts were prepared by mixing 0, 2 and 4 % P with FYM on dry weight basis either from RP (rock phosphate) or TSP (triple super phosphate fertilizer). The prepared composts were then applied to pots containing 6 kg of soil @ 160 mg P 2 O 5 kg -1 and data were recorded on phosphorus fractionations at 1st, 5th and 10th week of germination and its correlation with wheat seedlings growth and leaf [P]. Results showed that the labile P fraction initially increased and then decreased and as compared to control and untreated FYM composts, all treated pots maintained higher labile P at all the three sampling times. However, the moderately labile and non-labile fractions showed non-significant changes with time. The Plant height, biomass and total P uptake were found significantly higher in the treatment fertilized with 2 % TSP enriched compost followed by 4 % TSP enriched compost as compared to control. The effect of TSP enrichment was better than RP as well as the enrichment with 2 % was better than 4 % for both sources in both soils. Moreover, only labile P determined at 10 th week of germination and similarly leaf [P] at this stage showed significant correlation with plant growth. These results concluded that enrichment of composting material with P can enhance the bio-available P to plant and cab boost up the plant growth in calcareous soils.

The purpose of this study was to evaluate the capability of Aspergillus tubingensis and Talaromyces islandicus to solubilize inorganic phosphorus sources, their activity under abiotic stress, and the enhancement of P availability in soils and plant growth. The P-solubilizing capability and acidification mechanism of the strains were assessed in vitro using tricalcium phosphate and rock phosphate. Independent assays were conducted with rock phosphate under NaCl and fungicides carbendazim, chlorothalonil, and propamocarb hydrochloride using a factorial design. Thereafter, the effects of fungal inoculations in rock phosphate-amended soil and P nutrition of Zea mays were assessed in a greenhouse experiment. Both fungi solubilized P in vitro via acidification through the exudation of acetic, citric, lactic, malic, quinic, and succinic acids. The P-solubilizing efficiency of A. tubingensis was maintained above 97.5% under 0.5 to 3.0% NaCl, up to 28.7% in the treatment with carbendazim, up to 5.3% with chlorothalonil, and above 96.5% with propamocarb hydrochloride; while T. islandicus efficiency decreased to 45.2% in a NaCl concentration-dependent trend, and maintained it above 80% in the fungicide treatments. The inoculation with A. tubingensis increased the available P in the amended soil by up to 65% after 30 days and resulted in 87% higher foliar P content, 111% greater plant height, and 25% greater dry weight of maize shoots. Similarly, T. islandicus contributed to these parameters in 55, 67, 90, and 17%, respectively. These findings suggest their potential as qualified phosphorus solubilizing microorganisms to develop novel and sustainable approaches for P fertilization in agriculture.
