8. The chemical status of zinc in the soil with methods of analysis

Abstract

does not appear. First page follows. Introduction Zinc has long been known to occur in the soil in minute amounts, but little is known about the forms in which it occurs and the extent to which it occurs in forms available to plants. Rather recently, zinc deficiencies have been shown to be a cause of certain disorders of plants. In California an elaborate, systematic investigation has been made of the relation of zinc to little-leaf of deciduous fruit trees and to mottle-leaf of citrus trees; the history of this investigation and a review of literature on the subject is given by Chandler (6)4. These discoveries have emphasized the need for a laboratory test for available zinc in soils. Twenty or thirty years ago, a few European workers reported studies on zinc naturally present in soils and on its importance as a plant nutrient.

16. THE INFLUENCE OF LIGHT, TEMPERATURE, AND OTHER CONDITIONS ON THE ABILITY OF NITELLA CELLS TO CONCENTRATE HALOGENS IN THE CELL SAP

Abstract

1. By the use of a special analytical technique it has been possible to study the accumulation of halogens in the cell sap of Nitella. 2. From a dilute solution, Br may be accumulated in the sap in a concentration much greater than that of the external solution. The conductivity of the sap may be markedly increased by such accumulation. The process is a slow one so that a month or more may be required to approach equilibrium. 3. Cl may be lost from the cell as a result of the accumulation of Br and vice versa. Other reciprocal relations between Cl and Br are indicated. 4. At equilibrium practically as much Br accumulated in the sap with an external solution containing 1 milli-equivalent of Br as with one containing 5 milli-equivalents. 5. Light energy was indispensable to the accumulation of Br. The temperature coefficient was characteristic of a chemical process.

36. Availability of Plant Nutrients

Author

Subjects
Nutrient, Moisture, Agronomy, Soil Science, Environmental science, Growing season, Forage
Abstract

SummaryEasily water-soluble substances are classed as instantly available, therefore, not here discussed. Rate of becoming available of substances not easily water-soluble is the important question. How this is affected by some of the variables of the soil, the plant and the climate is indicated. Among these factors are: Physical, chemical, and biological conditions in the soil; the nature of the plant with respect to need for specific nutrients, its length of growing season, its ability to forage for itself; the character of the climate with respect to light, temperature, moisture and the length of the growing season.
