Abstract

Aims

Biochar has been used as an amendment to improve soil fertility and increase crop yield. A pot trial and incubation experiment were conducted to evaluate the effects of combined biochar and phosphate fertilizer applications on changes in soil physiochemical properties, photosynthetic parameters, and plant growth of Brassica napus L. in acidic soil.

Methods

Biochar (B) was applied at rates (B0: 0%, B1: 2%, and B2: 4% w/w) to the soil, while phosphorus (P) as KH2PO4 was added at P0: 0 mg kg–1 soil, P1: 100 mg kg–1 soil, and P2: 150 mg kg–1 soil. Non-amended soil served as the control (Ck).

Results

The study found that the maximum photochemical quantum yield of photosystem II (Fv/Fm) and non-photochemical quenching were affected by biochar and P fertilizer treatments. The Fv/Fm was significantly lower in the Ck while the highest in B2P1. Compared to the Ck treatment, the electron transport rate and photosynthetic rate were significantly increased under the application of biochar with P fertilizer. Additionally, malondialdehyde content declined by 68.9% when biochar was added with P fertilizer treatments. Furthermore, the plant P content and plant growth parameters were significantly increased. Biochar with and without P fertilizer treatments increased soil pH significantly, compared to the application of P fertilizer alone. Water-soluble P decreased with incubation time, while Al-P decreased significantly by 69.9% and 76.4% under B1 and B2 treatments, respectively, compared to CK.

Conclusion

The findings revealed a positive effect of the combined application of biochar with phosphate fertilizer on the growth of oilseed rape in acidic soil.

期刊介绍: Established in 1922, the Journal of Plant Nutrition and Soil Science (JPNSS) is an international peer-reviewed journal devoted to cover the entire spectrum of plant nutrition and soil science from different scale units, e.g. agroecosystem to natural systems. With its wide scope and focus on soil-plant interactions, JPNSS is one of the leading journals on this topic. Articles in JPNSS include reviews, high-standard original papers, and short communications and represent challenging research of international significance. The Journal of Plant Nutrition and Soil Science is one of the world’s oldest journals. You can trust in a peer-reviewed journal that has been established in the plant and soil science community for almost 100 years. Journal of Plant Nutrition and Soil Science (ISSN 1436-8730) is published in six volumes per year, by the German Societies of Plant Nutrition (DGP) and Soil Science (DBG). Furthermore, the Journal of Plant Nutrition and Soil Science (JPNSS) is a Cooperating Journal of the International Union of Soil Science (IUSS). The journal is produced by Wiley-VCH. Topical Divisions of the Journal of Plant Nutrition and Soil Science that are receiving increasing attention are: JPNSS – Topical Divisions Special timely focus in interdisciplinarity: - sustainability & critical zone science. Soil-Plant Interactions: - rhizosphere science & soil ecology - pollutant cycling & plant-soil protection - land use & climate change. Soil Science: - soil chemistry & soil physics - soil biology & biogeochemistry - soil genesis & mineralogy. Plant Nutrition: - plant nutritional physiology - nutrient dynamics & soil fertility - ecophysiological aspects of plant nutrition.
