Sources of plant nutrients and soil amendments
A large number of diverse materials can serve as sources of plant nutrients.
These can be natural, synthetic, recycled wastes or a range of biological products including microbial inoculants. Except for microbial inoculants (biofertilizers), all of these contain one, two or several plant nutrients in readily or potentially available forms. A certain supply of mineral and organic nutrient sources is present in soils, but these often have to be supplemented with external applications for better plant growth. In practical farming, a vast variety of sources can find use in spite of large differences in their nature, nutrient contents, forms, physicochemical properties and rate of nutrient release. These are not mutually exclusive but can be used together as components of INM.
Nutrient sources are generally classified as organic, mineral or biological.
Organic nutrient sources are often described as manures, bulky organic manures or
Organic fertilizers. Most organic nutrient sources, including waste materials, have widely varying composition and often only a low concentration of nutrients, which differ in their availability. Some of these, such as cereal straw, release nutrients only slowly (owing to a wide C:N ratio) while others such as the N-rich leguminous green manures or oilcakes decompose rapidly and release nutrients quickly.
Residues from processed products of plant or animal origin are increasingly important as nutrient sources and lead to nutrient saving by recycling. In addition, a very wide range of products obtained from the recycling of crop, animal, human and industrial wastes can and do serve as sources of plant nutrient. A significant amount of N is made available through BNF by a number of micro-organisms in soils either independently or in symbiosis with certain plants. The inocula of such micro-organisms are commonly referred to as

    Functionalism is a macro theory, which is based on society as a whole, rather than just that of the individual. It is argued that functionalism generates many things for society. Religion, from a functionalist point of view, socialises people, teaching them norms and values of society, which are the basis for social unity. Religion further is a structure within functionalism which aids in influencing individuals lives. Functionalism claims that social solidarity, the uniting of people in society is an important part of maintaining social order, which is a functional pre-requisite for society to survive. In addition, Functionalists use the term, ‘Organic Analogy’, which is the comparison between society and the human body. The idea that like organs is a necessary condition in a human body, ensuring it functions correctly, society has different institutions, like religion which join up with others to enable society to work well, maintaining mutual agreement in society.…

    All forms of life need energy, food and water, and plants are no exception. Without water, oxygen, carbon dioxide and numerous mineral elements, they would not able to survive. Plants take nutrients from the air, the soil, and the water. Of the minerals, plants need comparatively large amounts of nitrogen, phosphorus, potassium, calcium, magnesium and sulphur, which are called major or macronutrients. Numerous other elements, called micro-nutrients, are also needed in much smaller amounts. (Windridge 2000) The main three ingredients, Nitrogen (N), Phosphorus (P) and Potassium (K), together comprise over 75% of the mineral nutrients found in the plant. These three elements form the main ingredients of most fertilizers. These are marketed as N-P-K fertilizers, which stand for Nitrogen (N), Phosphorus (P) and Potassium (K), or compound fertilizers. They are labelled or named according to the content of these three elements. (Whiting 2009)…
