Solubility And Physiological Availability Of Phosphates In Sodium And Calcium Systems, Parker F. Pratt

One of the principal fertility problems of calcareous soils is the lack of available phosphates. The factors which control this availability are not completely understood. One hindrance to the solution of the problems involved results from confusion of the concepts of solubility and availability. Availability is the net effect of the chemical state of a plant nutrient element and the ability of the plant to utilize the forms of the element present under the existing chemical and physical environmental conditions. In this paper, the term solubility will be used to designate the chemical solubility of an element in water or …

Chlorosis of plants from a lack of available iron is one of the most common plant nutrient problems of the calcareous soils of the west. The disease is characterized by a yellowing of the plant leaves and is accompanied, in severe cases, by a partial root death and premature defoliation (3). In addition to reducing growth, the disease greatly reduces the quality and yield of plants.
Many types of plants are affected by iron chlorosis. In Hawaii and Porto Rico rice, sugar cane and pineapple are susceptible, while in California and Arizona, citrus trees are seriously affected. In Utah apples, …
