Effects of Application of Plant Organic Matter with a High Ratio of Carbon to Nitrogen on Dynamics of Inorganic Nitrogen in Soiland Plant Growth. MIZDA Yukie, Ryo MOCHINAGA, Mihoko TAKESHITA, Koga KAWASHITA and Hiroki MUTA (Fukuoka Agricultureand Forest Research Center, Chikushino, Fukuoka 818-8549, Japan) Bull. Fukuoka Agric. For. Res. Cent. 9: 22-26 (2023)
When organic matter with a high ratio of carbon to nitrogen is applied to soil, inorganic nitrogen in the soil is consumed by soil
microorganisms to decompose and increase the organic matter. This causes a shortage of inorganic nitrogen available for plants. On theother hand, when organic matter with a high ratio of carbon to nitrogen is applied to soil, the soil can contain more pore space andhumus, and physical properties are expected to improve. In this study, we investigated the dynamics of inorganic nitrogen in soil when
rice straw, wheat straw, rice husks, or bamboo, which have a high ratio of carbon to nitrogen and are easily available, were mixed with
VRLO:KHQWKHVRLOZDVLQFXEDWHGDWႏIRUZHHNVWKHDPRXQWRILQRUJDQLFQLWURJHQLQWKHVRLOZLWKHDFKW\SHRIRUJDQLFPDWWHU
decreased compared to that without mixing. In particular, the most significant decrease in inorganic nitrogen was observed when wheat
straw was used. In cultivation tests, when wheat straw was applied, leaf discoloration and a reduction in nitrogen absorption wereobserved. These effects were considered to be based on a decrease in inorganic nitrogen due to the decomposition of organic matter inthe soil. These results suggest that when organic matter with a high ratio of carbon to nitrogen is applied to soil, the amount of inorganic
nitrogen in the soil decreases, which may affect plant growth depending on the type of organic matter applied, and that nitrogen
fertilization should be increased.
