Applying fertilizer solutions through irrigation water is not a recent development. The first agricultural use of anhydrous ammonia was through application in irrigation water in the early 1930’s. With the mechanization of irrigation, particularly with the development of center pivot sprinkler systems, new application techniques have been developed for fertilizer and chemical solutions. New words describing these application techniques include fertigation, chemigation, fungigation, herbigation, insectigation, and pestigation.

Properly collecting soil samples is the most important step in any nutrient/soil amendment management program. Soil sampling should reflect tillage, past fertilizer/soil amendment placement, cropping patterns (and correcsponding irrigation requirements), soil type (including drainage and slope characteristics) and perhaps old field boundaries (such as old feed lots, windorws, altered stream beds, etc.). Trends toward reduced and/or zero tillage and technology for variable rate fertilization (VRF) have especially demanded that soil samples be taken more comprehensively and intensively for more accurate fertilizer and soil amendment application. This brochure will discuss the many methods used for taking an accurate soil sample using various methods and under several different types of tillage solutions.READ MORE
Interpreting Soil Analysis is one of Midwest Laboratories' most popular publications. This brochure will walk the reader through how to read the soil test. We explain the individual analysis and calculations. We also discuss the desired levels of different nutrients and soil properties.READ MORE
Modern agriculture demands top yields... and quality yields. Additionally, you demand profitable yields. In satisfying these demands, plant tissue analysis has become a valuable crop production tool. Top quality and profitable yields, unfortunately, don't just happen. Many factors need to be considered... like adequate moisture and fertility, proper plant population, adapted variety, disease and insect resistance and control... the list goes on. One of the more important factors affecting crop yields is the nutrient status of the plant... or the flow of nutrients to plant tissues during the growing season. Nutrient status is an "unseen" factor in plant growth, except when deficiencies become so acute that visual deficiency symptoms appear on the plant.READ MORE
