Plant and Soil, 1984
Earthworms redistribute organic materials within the soil, increase soil penetrability and, und certain conditions, influence ion transport in soils. Root distribution may be modified and microbial activity increased by their burrowing and feeding activities. Earthworms influence the supply of nutrients in several ways. Not only is earthworm tissue and

The activities of earthworms that have most influence on soil structure are: (1) Ingestion of soil, partial breakdown of organic matter, intimate mixing of these fractions, and ejection of this material as surface or sub-surface casts. (2) Burrowing through the soil and bringing subsoil to the surface.

Soil Fertility and Management of Malaysian Soils
2017Malaysian soils are highly weathered, acidic, and not very fertile for crop production. About 75" of these soils fall under the Ultisols and Oxisols soil group, which are normally found in tropical regions. Ultisols are usually acid soils, which have been formed under forest vegetation and are not natively fertile. Different types of soils are found in

Soil Nutrients (Soil Fertility)
1999Under the section on “Soil Aeration” (Chapter 4), it was explained that all living plants respire. This is the process where oxygen is used to burn food into carbon dioxide and water. Now we will consider another process used by green plants to manufacture their own food called “photosynthesis,” In photosynthesis, carbon dioxide and water are used ...

Soil Fertility, Fertilization and Nutrient Cycling
2019The most remarkable thing about Chernozem is the production from unfertilized fields. In long-term trials on the Typical chernozem of the Balţi Steppe, the mean yield of winter wheat at 4 t/ha is equivalent to the best achieved anywhere in Europe up until the 1960s, double the average in Russia over recent decades, and a very good yield on dryland ...

Soil fertility and plant nutrition
2013Plant nutrition and fertilization practices are important components of the GAP protocols. To contribute to successful application of GAP, this chapter gives a short overview of soil fertility, nutrient functions in plant metabolism, plant nutrient requirements, fertilization management, nutrient availability in the root zone and the impact of nutrient
