Study on the effect of organic fertilizers on soil organic matter and enzyme activities of soil in forest nursery

Abstract

The aim of the study was to assess the effects of organic fertilization on selected chemical properties of the soil and the activity of dehydrogenase and β-glucosidase in the soil of forest nursery. The main goal was to evaluate the role of organic fertilizers in carbon storage in the forest nursery soil. Sample plots were located in northern Poland in the Polanów Forest District on a forest nursery. Soil samples were collected from horizon 0-20 cm for laboratory analyzes. In soil samples pH, soil texture, and organic carbon, nitrogen, base cation contents, dehydrogenase activity and β-glucosidase activity were determined. The obtained results were used to evaluate the carbon storage. The results confirm the beneficial effect of the applied organic fertilizer on chemical properties of the soils under study and their biological activity. The applied organic fertilizers had an impact on increased accumulation of soil organic matter. In the soils investigated, there was an increase in the activity of such enzymes as dehydrogenases and β-glucosidase.

Risk of Heavy Metal Contamination in Vegetables Fertilized with Mushroom Residues and Swine Manure

“…The organic matter content in the soils treated with AB, FV, and SM increased on average by 14.4%, 16.4%, and 17.6% with each vegetable rotation; TN increased by 17.7%, 22.7%, and 24.0%; AN increased by 16.0%, 19.5%, and 19.1%; TP increased by 65.3%, 67.9%, and 73.7%; AP increased by 39.3%, 41.6%, and 48.4%; TK increased by 9.5%, 12.6%, and 13.3%; AK increased by 20.5%, 34.0%, and 40.6%, respectively. The results highly suggest that the application of mushroom residues and swine manure significantly increased the contents of organic matter and mineral nutrients in the soils, which is consistent with many previous studies [33][34][35][36][37].…”

Multifaceted Ability of Organic Fertilizers to Improve Crop Productivity and Abiotic Stress Tolerance: Review and Perspectives

“…Further, these authors also found that the replacement of chemical fertilizers with organic manures can increase macro-aggregates, POC, TOC and the yield of crops compared to conventional fertilizers [129]. Organic materials have a positive effect on increasing the SOM (on average 12.9%) compared to the control [130][131][132].…”

Aplikasi Pupuk Organik Diperkaya Mikrobia Pada Usaha Pembibitan Tanaman

“…Pupuk organik mampu meningkatkan ketersediaan hara tanah serta meningkatkan aktivitas mikrobia dalam tanah sehingga mampu menigkatkan kesuburan tanah (Piaszczyk et al, 2017). Hara tersedia yang cukup bagi tanaman menunjang pertumbuhan vegetatif dan pertumbuhan generatif tanaman (Andalasari et al, 2017), sehingga tanaman dapat tumbuh dengan baik dan proses pembungaan lebih cepat.…”
