The influence of lime and phosphorus application to three soils on yield and nutrient uptake by sorghum

It would, therefore, be evident that fertilizer experiments involving the use of lime and phosphates on acid soils will be quite important in reaching conclusions regarding the judicious use of these nutrients as well as fertilizers in general. This work was, then, undertaken with the following objectives in view:

(1) To study the influence of liming and phosphorus fertilization of different acid soils on the growth and uptake of phosphorus and cations by plants; and

(2) To study the influence of limestone and phosphate additions to different soils on the pH and phosphorus availability of the soils as measured by chemical means.
