![]() The Council on Soil Testing and Plant Analysis, established in 1969, promotes soil testing and plant analysis, including efficient use of nutrient resources, maximizing profits, and encouraging proper soil management and environmental protection. Soil testing and plant analysis are important components of the Food Security Act and under consideration as safeguards for the new Clean Water Act. Several states now require soil testing as part of their nutrient management programs. With the renewed current emphasis on agricultural production efficiency and environmental quality, the technology of soil and plant analysis has taken on even greater importance. This is a comprehensive presentation of useful information for the scientific and technical personals involved in such types of analysis. The purpose of this book 'Soil Testing and Analysis' is (i) to provide the vital plant nutrients functions for which soil testing is to be made (ii) to determine the nutrient status of the soil with appropriate methods, measurements and criteria for interpreting those assessments (iii) to analyze the appropriate parts of the plant samples for nutrient elements with available methods of analysis (iv) to analyze the important water quality parameters with interpretations and (v) to prepare the soil, plant and water samples for the analysis of pesticide residues with the different available methods. Our available water resources are diminishing and getting polluted with excess use of fertilizers and pesticides which are ultimately affecting the environment, food produced and water quality. The soil testing along with plant analysis gives the true status of plant nutrients affected by soil properties to take the proper care for the plant growth. The soil testing provides the status of the nutrients determined in the laboratory for the application of appropriate rate of fertilizers to eliminate the nutrients limiting for production. Plants need at least 16 essential elements for their normal growth and to complete their life. Most likely soil can efficiently sustain humanity with food, fibre, feed to animals and clean environmental maintenance only when it is considered and managed from the holistic and ecosystem points of view. The well being of the humans including animals depend upon very much on how the soil productivity is maintained without ecosystems degradation. ![]()
