碳占植物所需营养元素总量的50%以上,又是植物生命活动的能源。把碳与NPK排在统一序列(大量元素),是主次不分,导致肥料理论和造肥用肥技术的根本性错误。必须为碳正名确位:碳是植物的“基本元素”。碳是土壤肥力的缔造者和核心物质。土壤有机碳养分耗尽,导致土壤肥力衰竭,是土壤贫瘠化的主因。植物碳养分的存在形式 Carbon accounts for more than 50% of the total nutrients required by plants and is also an energy source of plant life activities. The carbon and NPK ranked in a unified sequence (a large number of elements), is the primary and secondary distinction, leading to fertilizer theory and fattening fertilizer technology fundamental error. The carbon name must be true: carbon is the “basic element” of the plant. Carbon is the creator and core substance of soil fertility. Soil organic carbon depletion, leading to depletion of soil fertility, is the main reason for the impoverishment of soils. Existence of Plant Carbon Nutrients
