Abstract excerpt
With solution culture experiment, this paper studied the effects of two potassium supply levels on the root exudates content and its dynamics of two grain amaranth genotypes (potassium-enrichment K12 and ordinary M9), and the activation of root exudates on soil mineral potassium. The results showed that the root exudation rates of soluble sugar, amino acids and organic acids of these two genotypes were decreased...
