摘要:
The Diagnosis and Recommendation Integrated System (DRIS) appears to be a more sensitive tool in the early detection of mineral deficiency in soybeans (Glvcine max. L.) than the sufficiency range approach. A small data bank based on information collected in a survey over a two‐year period on early maturing soybeans grown in Quebec was used to calculate new modified DRIS norms. Remedial measures predicted by DRIS gave greater yield increases than those with the sufficiency range approach. Regional deviation in norms were identified and were more important with ? related ratios
