Phosphorus is a primary factor of soil fertility as it is an element of plant nutrients in the soil. It is essential for cell division and plant development, especially in seedlings and young plants. [10] However, phosphorus is becoming increasingly harder to find and its reserves are starting to be depleted due to the excessive use as a ...
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
William Albert Albrecht (September 12, 1888 – May 19, 1974) [1] [2] chairman of the Department of Soils at the University of Missouri, was the foremost authority on the relation of soil fertility to human health and earned four degrees from the University of Illinois at Urbana–Champaign.
Liebig's law has been extended to biological populations (and is commonly used in ecosystem modelling).For example, the growth of an organism such as a plant may be dependent on a number of different factors, such as sunlight or mineral nutrients (e.g., nitrate or phosphate).
The soil texture determines the aeration, drainage, fertility, and porosity of the soil. Some soil variables of special interest to agricultural soil science are Soil texture or soil composition: Soils are composed of solid particles of various sizes. In decreasing order, these particles are sand, silt and clay. Every soil can be classified ...
Plant and Soil is a monthly peer-reviewed scientific journal covering research on the relationships between plants and soil, such as relationships and interactions of plants with minerals, water and microbes, the anatomy and morphology of roots, soil biology and ecology, etc.
Acta Agriculturae Scandinavica. Section B. Soil and Plant Science is a peer-reviewed scientific journal published by Taylor & Francis on behalf of the Nordic Association of Agricultural Scientists. It covers environmental sciences, botany, earth sciences, physical geography, ecology, and the soil sciences of relevance to agriculture.
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
