菠萝的生产产生了大量的收获和加工残留物,很少使用。本研究使用菠萝残留物和家禽垫料评估堆肥质量。测试了五种堆肥处理,以下不同比例的皇冠,菠萝加工废料(PPW),菠萝收获残渣(PHR),和家禽垫料(PL)。分析了各种参数,包括pH值,电导率,CO2释放速率,含水量,有机碳,含氮化合物,磷,钾,钙,镁,铜,和锌。此外,收集了生产者和加工者对堆肥质量的看法。结果表明,微生物分解温度升高,pH值,CO2释放,和氮含量,同时降低电导率和有机碳。堆肥表现出良好的作物施肥特性,其中C4(75%PHR+25%PL)堆肥表现出最好的化学性质。生产者和加工者更喜欢颜色,气味,和C4(75%PHR25%PL)和C5(56.25%树冠18.75%PPW25%PL)堆肥的结构。总的来说,菠萝残留物与家禽凋落物堆肥产生适合植物施肥的堆肥,特别是C4和C5配方,为农业中可持续的废物增值提供了潜力。
The production of pineapple generates significant quantities of harvest and processing residues, which are very little used. This study evaluates compost quality using pineapple residues and poultry litter. Five composting treatments were tested, varying following proportions of crown, pineapple processing wastes (PPW), pineapple harvest residue (PHR), and poultry litter (PL). Various parameters were analyzed, including pH, electrical conductivity, CO2 evolution rate, water content, organic carbon, nitrogen compounds, phosphorus, potassium, calcium, magnesium, copper, and zinc. Additionally, the perceptions of producers and processors regarding compost quality were gathered. Results indicated that microbial decomposition increased temperature, pH, CO2 release, and nitrogen content while reducing electrical conductivity and organic carbon. Composts demonstrated favorable characteristics for crop fertilization, with C4 (75% PHR + 25% PL) compost showing the best chemical properties. Producers and processors preferred the color, odor, and structure of C4 (75% PHR + 25% PL) and C5 (56.25% crown + 18.75% PPW + 25% PL) composts. Overall, composting pineapple residues with poultry litter yields composts suitable for plant fertilization, particularly C4 and C5 formulations, offering potential for sustainable waste
valorization in agriculture.
