1. Comparative DRIS and Crop Log Diagnosis of Sugarcane Tissue Analyses

Author:
C. A. Jones; J. E. Bowen
Source:
Agronomy journal 1981 v.73 no.6 pp. 941-944
ISSN:
0002-1962
Subject:
Diagnosis and Recommendation Integrated System; Saccharum; fertilizers; nutrient content; nutrient deficiencies; sugar industry; sugarcane; Hawaii (island)
Abstract:
... The Crop Log system of sugarcane (Saccharum spp. hybrid) tissue analysis is a critical concentration approach which is widely used for the diagnosis of nutrient deficiencies and imbalances in the Hawaii sugar industry. Recent studies conducted elsewhere suggest that the Diagnosis and Recommendation Integrated System (DRIS), which utilizes ratios of tissue nutrient concentrations rather than the co ...

3. Soil Testing, Foliar Analysis, and DRIS as Guides for Sugarcane Fertilization

Author:
A. M. O. Elwali; G. J. Gascho

Agronomy journal 1984 v.76 no.3 pp. 466-470
ISSN:

Diagnosis and Recommendation Integrated System; Saccharum; calcium; copper; farmers; fertilizers; iron; leaf analysis; leaves; magnesium; manganese; muck soils; nitrogen; nutrient balance; nutrient content; phosphorus; planning; potassium; ratooning; soil sampling; sugarcane; sugarcane soils; sugars; zinc; Florida
Abstract:
... Foliar analysis has been practiced widely in sugarcane (a complex trispecies hybrid of Saccharum) for planning and evaluation of fertilizer programs and harvest schedules. On the mainland of the USA, sugarcane farmers have traditionally relied on soil testing to plan fertilizer programs. Soil testing remains an excellent preplant practice but its reliability for the successive ratoon crops has bee ...

4. Sugarcane Response to P, K, and DRIS Corrective Treatments on Florida Histosols

Author:
A. M. O. Elwali; G. J. Gascho
Source:
Agronomy journal 1983 v.75 no.1 pp. 79-83

Subject:
Diagnosis and Recommendation Integrated System; Histosols; Saccharum; calcium; copper; fertilizers; hybrids; iron; leaves; magnesium; manganese; monitoring; nitrogen; nutrient balance; nutrient content; nutrients; nutritional status; phosphorus; planting; potassium; sugarcane; sugars; zinc; Florida
Abstract:
... Nutritional imbalances in sugarcane (a complex trispecies hybrid of Saccharum) on Florida Histosols (Medisaprists) were suggested in earlier studies. In order to eliminate possible imbalances among nutrients, the Diagnosis and Recommendation Integrated System (DRIS) was adapted to monitor the nutritional status of sugarcane in an experiment with varying P and K levels. Standard DRIS reference norm ...
