concept of nutrient availability

Concept of Nutrient Availability - Soil is a living medium consisting of physical part - called as soil particles, chemical part - consisting of various compounds as well as biological part - consisting of various microbes, vertebrates, invertebrates inhabiting in soil..

Soil is a living medium consisting of physical part - called as soil particles, chemical part - consisting of various compounds as well as biological part - consisting of various microbes, vertebrates, invertebrates inhabiting in soil. Unless all these components are kept in harmony, the crop..

Just as the human body needs nutrients for its healthy growth, plants also need certain nutrients for their growth. The nutrients required by plants for their healthy growth are 16 in number. They are carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, ..

One crop component requires more nutrients and the other requires lesser nutrients. Mixed cropping is done to reduce the competition between component crops for light, nutrients and water. If one crop fails due to shortage of moisture or insufficient availability..

These are nutrient supplements for plants manufactured in fertilizer factories from chemicals. They are nutrient specific i.e., they may provide only nitrogen, only phosphorus or only potassium to the soil. They are often used when a particular nutrient is required in ..

Chemical Fertilizers - These are nutrient supplements for plants manufactured in fertilizer factories from chemicals. They are nutrient specific i.e., they may provide only nitrogen, only phosphorus or only potassium to the soil. They are often used when a particular nutrie..

In this each population inhibits the other indirectly for the resource in short supply. Example: Trees, shrubs and herbs in a forest, struggle for sunlight, water and nutrients. Similarly, grasshoppers, rats, rabbits, deer (herbivores) compete for food especially during draught and less ..

Is a direct food related interspecific interaction in which one partner called scavenger or saprobiont eats the dead bodies of other animals, which have died either naturally or killed by some other animals. Scavengers clean the environment and the available food is ultimately disposed o..

. Among them, nutrient management techniques aim at providing sufficient nutrients at the required stage in the required form, while water management techniques aim at providing ideal situations for growth of crops. Weed management techniques aim at keeping the land weed free so..

Acid rain chemically strips waterways of necessary nutrients and lowers the pH to where plants and animals cannot live. Most of the aquatic animals cannot survive when the pH is less than 4. Some species of fish, such as salmon, die even when the pH is less than 5.5. Certain species of a..
