The impact of sewage sludge and compost on winter triticale

Abstract

There is an increasing interest in the agricultural application of organic waste such as soil amendment, due to the possibility of recycling valuable components, organic matter, and nutrient elements necessary for plant growth. The present study was carried out to evaluate the effects of sewage sludge, and green waste compost application, on a forage crop, triticale "X Triticosecale Wittmack" compared to unfertilized control. The experimental design was installed in the glasshouse conditions at the Regional Field Crop Research Center in Beja, Tunisia. Sewage sludge and green waste compost were added by four rates (0, 5, 10, and 20 t/ha) in soil, 15 days before triticale sowing. The main results showed that plant response differs depending on the type of adding fertilizer. Indeed, compost inputs decreased shoot length and production of triticale, among all sewage sludge rates, by average values of 26 and 60% respectively at final harvest, as compared to unamended soil. However, amendment with different rates of sewage sludge significantly (p < 0.05) increased different plant growth and yield attributes.

Lodging resistance and feeding quality of triticale and cereal rye lines in an alpine pastoral area of P. R. China

“…Studies on triticale have mainly focused on its molecular biology (Kselíková et al, 2020), breeding (Aliyeva et al, 2020;Neuweiler et al, 2020), pathology (Rodriguez-Algaba et al, 2019), forage production and nutrition (Giunta et al, 2020;Kchaou et al, 2017;Maxin et al, 2017), and cold…”

The research on lodging resistance of triticale is mainly the selection of low cultivars (Litvinov et al., 2020), and the research on the influence of its stalk structure and chemical composition on lodging resistance has not been seen.…”

Classification and Disposal Strategy of Excess Sludge in the Petrochemical Industry

“…Although a large variety of reports on the disposal of excess sludge, the environmental risks arising from the disposal of excess sludge need to be evaluated. For example, with respect to the excess sludge for land using, the potential for soil improvement and utilization [16] and the impact on plants [17,18] should be analyzed. Meanwhile, the migration of heavy metals of excess sludge in the process of soil utilization should be studied [19].…”
