Cím:	Effect of pellet compost on CO2 and N2O production and plant growth in Andosol and Chernozem / Sato Makiba, Magdolna Tállai, Andrea Balláné Kovács, Imre Vágó, János Kátai, Miwa Yashima Matsushima, Kazuyuki Inubushi
Dátum:	2020
Megjegyzések:	Compost is attracted in organic farming as an alternative to chemical fertilizers in the world. Pellet compost consists of a mixture of compost and chemical fertilizer, odorless, easy to handle and adjustable composition. Although it has pointed out that pellet compost generates greenhouse gases such as carbon dioxide (CO?), and nitrous oxide (N?O), the mechanism is not clearly understood. To investigate the effect of compost on greenhouse gas generation and plant growth in Hungarian soils, Chernozem and Japanese soil, Andosols, incubation experiments and pot experiment were conducted. Chernozem collected in University of Debrecen, Hungary, and Andosol collected in Chiba University, Japan, were used. Treatments were 1) pellet compost made of pig manure with chemical fertilizer, 2) chemical fertilizer, comparing to 3) no fertilizer. Soils were incubated for 6 weeks at 20? in a dark place and analysed for CO?, N?O production and content of nitrogen. In similar soils and treatments, pot experiment was conducted with Komatsuna (Brassica rapa) to observe the effect on plant growth. Production rate of N?O with chemical fertilizer in Chernozem was the highest among the three treatments. However N?O was not detected in Andosol. It was probably due to higher clay contents in Chernozem and higher activity of denitrification bacteria than in other treatments. In Chernozem, as nitrification rapidly progressed in chemical fertilizer, N?O production was the highest as by-products of nitrification. CO? production of Chernozem was higher than that of Andosol. This is attributed to be stimulated decomposition of organic matter by the soil microbial activity. In pot experiment, pellet compost tended to enhance plant growth, followed by chemical fertilizer and control in both soils. These experiments showed that pellet compost is expected to have carbon storage effect and leading to be a sustainable agriculture by alternative to chemical fertilizer.

Cím:	Effects of a new compost-chemical fertilizer mixture on CO2 and N2O production and plant growth in a Chernozem and an Andosol / Makiba Sato, Magdolna Tállai, Andrea Balláné Kovács, Imre Vágó, János Kátai, Miwa Yashima Matsushima, Shigeto Sudo, Kazuyuki Inubushi

Megjegyzések:	Composts are an attractive organic-farming alternative to chemical fertilizers and are used for carbon sequestration to increase soil carbon storage. In Japan, a new type of mixed compost fertilizer called compost-compound fertilizer mixture (CCFM) has been registered. It exhibits several merits for organic farming; that is, it is odorless, easy to handle, and has a controllable nutrient content. CCFM consists of compost mixed with chemical fertilizer, such that nutrient content can be effectively adjusted. Although it has been pointed out that pellet composts generate more greenhouse gas emissions (GHGEs), such as carbon dioxide (CO2) and nitrous oxide (N2O), the mechanism involved is not clearly understood. To investigate the effect of CCFM on GHGEs, soil microbial properties and plant growth, incubation and pot experiments were conducted in a Hungarian Chernozem and a Japanese Andosol. Both soils were incubated with 1) CCFM prepared using pig manure mixed with chemical fertilizer, 2) chemical fertilizer only, or 3) no fertilizer. A pot experiment was conducted using Komatsuna (Brassica rapa). In the Chernozem, the maximum N2O production rate was observed after chemical fertilizer treatment. The emission factors of chemical fertilizer and CCFM were 0.25% and 0.19%, respectively. In contrast, N2O production was not detected in the Andosol. Meanwhile, CO2 production was higher (P < 0.05) in the Chernozem than in the Andosol; furthermore, it was higher under CCFM than under chemical fertilizer treatment, with 7.5% of amended carbon changing to CO2, thus suggesting that dominant carbon remained in the soil. Microbial biomass increased faster in the Andosol than in the Chernozem and the change was faster under the CCFM than under the chemical fertilizer or control treatments. In the pot experiment, CCFM tended to enhance plant growth in both soils. These experiments showed that CCFM has a soil-carbon storage effect with less resultant GHGEs, especially in Andosols, thereby leading to a more sustainable agriculture. Nonetheless, further studies are required for long-term experiments with other crops.
