Efficient nitrogen fertilization for sustainable sago palm (Metroxylon sagu Rottb.) cultivation in Tropical Peatland

Autor: Yuka Sasaki, Ho Ando, Ken-Ichi Kakuda, Lulie Melling, Akira Watanabe

Publikováno v: Plant Production Science, Pp 1-11 (2024)

Tropical peatlands degraded by agricultural use with intensive drainage require restoration through rewetting, preferably while agricultural use continues. Sago palm (Metroxylon sagu Rottb.), a starch crop that can grow in high water table peatlands,

Potassium balance in paddy fields under conventional rice straw recycling versus cow dung compost application in mixed crop–livestock systems in Japan

Autor: Thanh Tung Nguyen, Yuka Sasaki, Misa Aizawa, Ken-ichi Kakuda, Hiroshi Fujii

Publikováno v: Soil Science and Plant Nutrition. 69:36-44

Potassium (K) fertilizer consumption in rice production has increased in developing countries where negative K balance was observed, but it has recently decreased in Japan. This situation raises a question of how K fertilization is managed in Japanes

On-farm assessment of the phosphorus balance of paddy soil fertilized with cow dung compost in mixed crop–livestock systems and with rice straw in conventional practice in Yamagata, Japan

Autor: Yuka Sasaki, Misa Aizawa, Tung Thanh Nguyen, Ken-ichi Kakuda, Weiguo Cheng, Hiroshi Fujii

Publikováno v: Soil Science and Plant Nutrition. 67:566-575

Rice straw (RS) and cow dung compost (CDC) are good sources of phosphorus (P) to support rice production. Our previous research found that CDC application in mixed crop-livestock systems supplied m...

Sago palm (Metroxylon sagu Rottb.) is the most promising starch producing palm species. Sago palm accumulates around 200 kg starch or more per plant or in the trunk. This palm species is recognized as one of the crops used by human beings since ancie

Comparison of paddy soil fertility under conventional rice straw application versus cow dung compost application in mixed crop–livestock systems in a cold temperate region of Japan

Autor: Ken-ichi Kakuda, Tung Thanh Nguyen, Yuka Sasaki, Hiroshi Fujii

After the rice harvest in Japan, rice straw (RS) is usually cut by combine harvester and incorporated into the soil to improve its fertility. In mixed crop–livestock systems, however, RS is collected and used as livestock feed, and cow dung compost

Comparison of the nitrogen balance in paddy fields under conventional rice straw application versus cow dung compost application in mixed crop–livestock systems

Autor: Ken-ichi Kakuda, Tung Thanh Nguyen, Hiroshi Fujii, Yuka Sasaki

In Japan, rice straw (RS) is commonly incorporated into the soil after harvest to maintain the fertility of paddy soil. However, in mixed crop–livestock systems, RS is collected to feed livestock and then cow dung compost (CDC) is applied to the fi

Effects of slag silicate fertilizer on silicon content of rice plants grown in paddy fields on the Shounai Plain, Yamagata, Japan

Autor: Ho Ando, Yuka Sasaki, Shuhei Makabe-Sasaki, Ken-ichi Kakuda

Publikováno v: Soil Science and Plant Nutrition. 60:708-721

Slag silicate fertilizer (SSF) is applied to paddy fields with different soil chemical properties to increase silicon (Si) concentration in rice (Oryza sativa L.) plants. However, the effects of soil chemical properties on Si availability of SSF to r

Early growth stage water management effects on the fate of inorganic N, growth and yield in rice

Autor: Yuka Sasaki, Ho Ando, Ken-ichi Kakuda, Shuhei Makabe-Sasaki, Shah Moinur Rahman

Publikováno v: Soil Science and Plant Nutrition. 59:921-932

Water and nitrogen (N) play vital roles in rice (Oryza sativa L.) production. Water-saving management decisions can influence soil conditions (oxidation and reduction), and these soil conditions affect the fate of N in paddy soil. We designed three i

Fate of Microelements Applied to a Tropical Peat Soil: Column Experiment

Autor: Akira Watanabe, Ho Ando, F.-S. Jong, E. Miyamoto, Ken-ichi Kakuda

Publikováno v: Communications in Soil Science and Plant Analysis. 44:2524-2534

Lack of microelements is a major problem in crop production in tropical peatland. For their efficient application, the fate of copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) in a Histosol was investigated in a 3-month column experiment. Leachi
