Relationship between Diagnosis and Recommendation Integrated System (DRIS) Optima and Foliar Nutrient Critical Levels

Soil Science Society of America Journal, 1990
Abstract Optimum nutrient levels for loblolly pine ( Pinus taeda L.) were estimated by applying DRIS techniques to 504 randomly selected trees from loblolly pine plantations in Georgia and South Carolina.

6. Foliar Diagnosis and Fertiliser Prescription in Forestry—The DRIS System and its Potential

South African Forestry Journal, 1987
SYNOPSIS Problems associated with current foliar diagnosis techniques are reviewed. Many of these problems have been overcome in agricultural crops by use of the Diagnosis and Recommendation Integrated System (ORIS). The foundation of DRIS is the concept of nutrient balance, the interrelationships among all nutrients being considered simultaneously ...

Non‐homogeneity of boron distribution in plants and consequences for foliar diagnosis

Communications in Soil Science and Plant Analysis, 1994
Abstract Soil and plant analyses are useful diagnostic tools only if they supply adequate information about the current state and can predict effects of different types of management. The prerequisites for reproducibility and consistency may not be met with boron which is not distributed homogeneously in plants.
