“…The lowest residual effect of the coarse FMP on Tifton 85 dry matter yield in the second harvest, differ from a series of studies in the literature BARBOSA FILHO, 2007;CASTRO, 2011;MOREIRA et al, 2014;BARBOSA et al, 2015) which FMP presented a superior residual effect compared to a soluble source (TS). As for FMPs, the process of P dissolution is slow, since it depends on chemical reactions with the soil (BUSTAMANTE et al, 2016).…”

“…Nevertheless, it is necessary to establish more precise criteria for P recommendation. Thus the possibility to apply rock phosphates at relatively low cost has been emphasized as a viable alternative to supplement P demand to the crops in tropical highly weathered soils CASTRO, 2011;GUEDES et al, 2012;WALKER et al, 2012;KNOX et al, 2014;TIECHER et al, 2014;BARBOSA et al, 2015;BUSTAMANTE et al, 2016).…”

Acid reactions and low available phosphorus in tropical soils limit forage yield. The aim was to evaluate soil chemical characteristics pH, P and Mg, forage nutritive values, critical soil and plant P levels and the residual effect of each source. The experiment was in a greenhouse with a Rhodic Haplustox, loam texture. Experimental design was a 5 x 4 factorial with five replicates which phosphate fertilizers were triple superphosphate, reactive rock phosphates Gafsa and Arad, and fused magnesium phosphate powder and coarse, applied at rates of 30, 60, 90 and 120 mg kg-1 P and a control treatment without P. The effectiveness of rock phosphates increased due to their residual effect. The coarse fused magnesium phosphate resulted in the lowest efficiency. The P critical level in soil and plant were 18 mg kg-1 and 2.4 g kg-1, respectively. The increase of phosphorus rates provided an increase in crude protein content.

“…Dramatic increases in green waste (GW) due to the rapid development of urban greening areas globally has become a major environmental challenge that has created social problems in developed and developing economies (Rashad et al 2010). GW mainly includes branch cuttings, tree wood and bark, pruning from young trees and shrubs, fallen dead and green leaves, grass clippings, garden litter and trimmings (Bustamante et al 2016). GW is generated by municipal parks, gardens, reserves, and domestic gardens.…”

“…In addition, GW is more environmentally friendly than other types of waste as it contains a lower level of micro-pollutants. This facilitates the production of a compost that is within utilization restrictions and quality standards that can be used in organic agriculture (Bustamante et al 2016).…”

“…Thus, shortened processing times and improved compost quality have become important goals in composting GW (Zhang and Sun 2016a). Various strategies and methods that were developed for optimization of GW composting have led to a reduction of the processing period, minimization of gaseous emissions, and the enhancement of compost quality (Belyaeva and Haynes 2009;Zhang et al 2013;Zhang and Sun 2016a;Bustamante et al 2016).…”

Purpose Green waste (GW) composting is of increasing importance to the waste management industry in addition being a useful agricultural product that is rich in nutrient and organic matter (OM). The combination of aerated static windrow with GORE( R ) cover membrane and an air-floor aeration system is a relatively new industrial-scale composting technology that has not been previously explored. Therefore, the aim of this research study was to evaluate the effectiveness of composting GW using this new technology. Methods The composting process was monitored through changes in the physico-chemical properties, E 4/6 , and fourier transform infrared (FTIR) spectra. Results Disinfection requirements were met by holding composting temperature steady in the thermophilic range for 24 days. The technology greatly improved composting conditions, and final compost product in terms of temperature, pH, electrical conductivity (EC), C/N ratio, OM degradation, nitrogen transformation, humification, and cation exchange capacity (CEC). The FTIR spectra revealed that there was enrichment of aromatic compounds and reduction in aliphatic structures and easily assimilated peptide components by microorganisms, indicating the humification degree increased, the final compost stabilized, and confirming the efficiency of composting. Consequently, the new technology produced a mature compost in only 30 days compared with the standard period of 90-270 days for traditional composting. Conclusion Notably, the new technology may be a sustainable alternative for GW management that converts waste into compost and could be beneficial for agricultural uses.

There are few reports on the material transformation and dominant microorganisms in the process of greening waste (GW) composting. In this study, the target microbial community succession and material transformation were studied in GW composting by using MiSeq sequencing and PICRUSt tools. The results showed that the composting process could be divided into four phases. Each phase of the composting appeared in turn and was unable to jump. In the calefactive phase, microorganisms decompose small molecular organics such as FA to accelerate the arrival of the thermophilic phase. In the thermophilic phase, thermophilic microorganisms decompose HA and lignocellulose to produce FA. While in the cooling phase, microorganisms degrade HA and FA for growth and reproduction. In the maturation phase, microorganisms synthesize humus using FA, amino acid and lignin nuclei as precursors. In the four phases of the composting, different representative genera of bacteria and fungi were detected. Streptomyces, Myceliophthora and Aspergillus, maintained high abundance in all phases of the compost. Correlation analysis indicated that bacteria, actinomycetes and fungi had synergistic effect on the degradation of lignocellulose. Therefore, it can accelerate the compost process by maintaining the thermophilic phase and adding a certain amount of FA in the maturation phase.
