Nutrición Vegetal y Fertilización
What do I need to know about soils? Soil can be living or dead. Living soil continuously requires enough air, water and soil organic matter in order to provide a good growing environment for plants and soil organisms. By providing these, even dead soil can manage to live again. You can tell whether your soil is living or dead by the amount of farm products that can be obtained from it under average management conditions. A living soil can support consistent and sufficient production of farm products while a degraded and dead soil cannot.
Over the past several years, many people have begun raising earthworms as a source of income or as a means of managing organic waste. Some are drawn to the business by extravagant claims of vast potential markets for earthworms in large waste disposal systems and agriculture and as a source of food for animals. Despite these claims, the current major commercial use of earthworms is as bait for freshwater sport fishing.
