【盲点】肥料代をドブに捨てるな！窒素が効かなくなる恐怖の欠乏症とは

"Even though I've been applying fertilizer properly, my yield has dropped this year for some reason." — The cause might be a molybdenum deficiency. This is about trace elements that rice farmers should know.

However, as a material for "nitrate reductase," it is essential for the process by which rice plants convert nitrogen into amino acids and proteins. If molybdenum is deficient, no matter how much nitrogen fertilizer is added, it will not be effectively utilized within the rice plant, leading to a decrease in yield and quality. Furthermore, "hydrogen sulfide" (that rotten egg smell) generated in rice paddies during the hot summer months damages the rice roots and causes autumn decline. Research by the National Agriculture and Food Research Organization has revealed that molybdate ions can suppress the generation of this hydrogen sulfide. If you are troubled by yellowing that doesn't improve even with top dressing, please take a look. Acid soils are prone to deficiency. Adjusting the pH with lime application directly improves the efficiency of molybdenum utilization. [Editor's Note] While studying molybdenum, I felt like I was gradually solving my long-standing question: "Why are there rice paddies where fertilizer doesn't work?" It's not just nitrogen that's needed, but also the "unsung heroes" that help utilize that nitrogen. I was reminded of the importance of pH management, and I hope this video will inspire farmers to re-evaluate their soil preparation.
