Importance of Soil Analysis

Australian Journal of Experimental Agriculture 33 8 - Published: Food, fibre and pharmaceuticals from animals. Shopping Cart: empty. Search our journals. Abstract During the past 3 4 decades, there has been a modest growth in the demand for soil amd plant testing services in Australia. Such development reflects an increasing awareness by farmers that there are tangible benefits from the regular use of soil and plant analysis. Concomitant with these changes, there has been an increasing breadth and sophistication in the range of available services, instrumental advances that permit more rapid analytical throughput, evolution of computer management systems including computer-generated reports , and a general decrease in reporting time to primary producers.

Here each chapter or section of the book is devoted to a specific analysis or group of related analyses, and gives the working details of all or nearly all the existing methods. Such books are not only very useful and convenient but also are a necessity for those analysts to whom the original papers in the literature are not easily accessible. It is, however, the other class of book that the analyst most appreciates, namely, the book in which he is not bewildered by an array of methods but is presented with a selection recommended from considerable experience.

Soil analysis is a set of various chemical processes that determine the amount of available plant nutrients in the soil, but also the chemical, physical and biological soil properties important for plant nutrition, or "soil health". Chemical soil analysis determines the content of basic plant nutrients; nitrogen N , phosphorus P2O5 , potassium K 2 O , pH, humus content, total CaCO3, available lime, organic matter, total sulphur S , trace elements, and other physical characteristics capacity, permeability, density, pH - value. Soil analysis imply :. According to the content of nutrients in the soil obtained by chemical analysis and the requirements of the culture for a certain yield, it is easier to determine the amount of required fertilizer to achieve high and quality yields. High quality soil analysis is basis of planning of fertilizing, and thus the quality of the entire production cycle, which results in a high quality and yield and better farm management. When to make a soil analysis?

Iron chlorosis caused by an elevated soil pH remains an important selection criteria in evaluating hybrid Populus trials in northwest New Mexico. Compared to expensive extraction methods or visual ranking scales, the soil plant analysis development SPAD chlorophyll meter is a handheld tool that objectively indicates leaf color. Based on the total chlorophyll content supported with foliar element data , Fe sufficiency threshold values from SPAD measurements were estimated in these two clones.
