long term impact of sewage sludge digestate and mineral fertilizers on Plant Yield and soil biological activity
Journal of Cleaner Production, 2018Co-Authors: Grzegorz Siebielec, Sylwia Siebielec, Dominik LipskiAbstract:Abstract The aim of the study was to assess a long-term impact of the cumulative application of sewage sludge on Plant Yield and soil microbial parameters. The study was conducted in 1 m2 lysimeter plots. In 2006 sewage sludge was applied to selected plots at the rate of 100 t of dry matter per hectare while the other plots were fertilized with mineral nitrogen. After 6 years, the same sludge rate was applied to selected plots in order to achieve single or cumulative sludge rates. The sludge plots were compared to the plots constantly fertilized with ammonia nitrate and the plots treated with digestate. Sludge stimulated an increase in Plant biomass similar or higher than the effect of mineral nitrogen fertilization. The highest enzyme activities were recorded for the cumulative sludge rates but the soils treated with single sludge rate also exhibited a high activity of alkaline phosphatase and dehydrogenases. The count of culturable microorganisms reflected trends observed for the enzyme activities. The study revealed that sewage sludges that meet the quality standards for application in agriculture stimulate both the soil microbial activity and the number of microorganisms even when applied at high reclamation rates.

The effects of struvite and sewage sludge on Plant Yield and the microbial community of a semiarid Mediterranean soil
Geoderma, 2019Co-Authors: Felipe Bastida, Nico Jehmlich, J. Martínez-navarro, V. Bayona, C. García, J.l. MorenoAbstract:Abstract Phosphorus (P) limitation will play a key role in the productivity of agriculture in the coming decades. Struvite is an ammonium magnesium phosphate mineral that can be recovered from wastewater-treatment Plants and can be considered as an alternative source of P. However, the impact of struvite on the Plant Yield and, particularly, on the soil microbial community is barely known. Here, we tested the impacts of struvite, sewage sludge, and their combination on the barley Yield, soil macro and micronutrients, and biochemical and microbiological soil properties. Amendment with struvite alone and its combination with sludge increased the availability of P in soil, the Plant uptake of P and Mg, and the barley Yield. The analysis of phospholipid fatty acids (PLFAs) and the utilization of metaproteomics approaches revealed significant effects of struvite on the biomass of Gram-positive bacteria and, particularly, on actinobacterial and verrucomicrobial populations in soil.

pengaruh jenis pupuk organik dan varietas terhadap pertumbuhan dan hasil tanaman cabai capsicum annum l
Jurnal Floratek, 2012Co-Authors: Erita Hayati, T Mahmud, Riza FazilAbstract:This study was aimed at determining effects of organic fertilizer types and varieties on growth and Yield of pepper and interaction between both factors. The research was conducted at Experiment Station of Agriculture Faculty, Syiah Kuala University, Darussalam Banda Aceh, from June to October 2010. The experiment used a randomized complete block design (RCBD), 3 x 2 with three replications. Factors studied were types of organic fertilizer, consisting of compost and cow manure and varieties, consisting of TM-999 and local varieties. Variables observed were Plant height at ages of 15, 30 and 45 days after Planting (DAP), number of productive branches, number of fruits per Plant, fruit weight per Plant, Yield per plot and production per ha. Results showed that there was no significant interaction between organic fertilizer types and varieties on all observed variables. Organic fertilizers did not significantly affect Plant height at ages of 15, 30 and 45 DAP, productive branches at age of 75 DAP, number of fruits per Plant, fruit weight per Plant, Yield per plot, and Yield per ha. Varieties significantly affected Plant height at age of 30 DAP, number of fruits per Plant, but did not significantly affected Plant height at ages 15 and 45 DAP, number of productive branches at age of 75 DAP, fruit weight per Plant, Yield per plot, and Yield per ha.
