Recycling of Cotton Stalks With Rice Straw to Compost as Friendly Technology to the Environment

Abstract

Two aerobic trapezoidal heaps of compost were practiced to investigate the value of bio-enrichment of chopped plants residues (cotton stalks and rice straw) through inoculation the mixture of these residues and some organic and mineral amendments with lignocellulytic fungi during the active composting in relation to their capacity to accelerate lignocellulose degradation. Also, some plant growth promoting rhizobactria were applied to the composted materials at maturity stage to study their ability to improve the biological and nutritional quality of the produced compost. Results of monitoring the composting process exerted that the physicochemicals and microbiological properties of the composted materials were developed with progressing of the process until 90 days. However, bio-enriched heap exhibited more acceleration than unenriched one with regard to reduce the organic carbon and C/N ratio. In addition, the maturity indices exerted acceptable values for generation index, CO2evolution, dehydrogenase activity and ratio of NH + 4/NO-3 as an indicator to nitrification process.

Quality assessment of compost produced from cotton stalks and rice straw

“…May (2022) refers to composting the purposeful accumulation of organic matter or biomass that is allowed to decompose in order to be used as an additive to improve soil properties. Mohamed et al, (2010) stated that Cotton is one of the important strategic crops in Egypt, and subsequently, Cotton stalks as a post-harvest by-product are in large quantities, reaching tens of thousands of tons annually. Therefore, that might cause many problems, such as storage on the roofs of houses, and disposal by burning which cause environmental pollution.…”

Characterization and metal loading capacity of humic acids derived from composted rice straw and olive pomace affected by the humification degree

“…Complexation with the hydrophilic part of HAs has been formed due to the interaction with metal ions, also increasing the ratio of aromatic structure (Dudare & Klavins, 2013). (Mohamed et al, 2010) Humic substances complexing capacity varies as a function of pH. Two binding patterns are possibly presented at acid-neutralpH (carboxylates) and alkaline pH (carboxylate and phenolic groups).…”
