Concentration of Nutrients like Nitrogen, Phosphorous available to plants for uptake

Soils or mediums with pH less than 7.0

Condition of soil/medium where oxygen is available

Condition of soil/medium where oxygen is not available

Describe the condition where pH is higher than 7.0

Any organic material added to medium for improving physical or chemical properties of soil.

Nitrogen containing compounds required for production of proteins

A negatively charged ion like Nitrate NO3-2

Tiny microscopic organisms required for recycling of nutrients / decomposition of organic matter

It’s the ability of soil to resist change of pH

Weight per unit of material, or weight of material in a standard volume.

 

Complex and simple sugars used as energy source both in plants and human beings.

Positively charged ions like Calcium, Magnesium.

It is the capacity of any material/soil to hold nutrients or capacity of soil to exchange Cation between soil and solution.

Ratio of Carbon to Nitrogen present in soil that determine nutrient release from organic sources with the help of bacteria

These are certain organic molecules that stop reaction of highly reactive Cations and prevents them from forming insoluble compounds.

A condition in plant leaves where leaves turn yellow normally due to Iron or Nitrogen deficiency

Aerobically decomposed remnants of organic material.

Stands for Electrical Conductivity. Its value shows presence of soluble salts in any material or solution.

These are proteins that act as catalyst in chemical reaction without becoming a part of reaction.

Application of fertilizer or pesticide on plant leaves

These are compounds given to plants either through soil or leaves to promote growth. They can be supplied by Organic or Inorganic means.

Application of fertilizers to plants through irrigation

It is the condition of soil that represents the presence of moisture content in soil after excess water has drained out.  Its also called as the “natural” moisture holding capacity of any medium.

A process used in conversion of carbohydrates into alcohol or energy production under aerobic/anaerobic conditions.

Metals with densities 5 mg or higher

High molecular weight dark brown substance derived from humus by using alkalis. In simple terms, it’s the final form of decomposed organic material.

Loss of plant nutrients from root zone due to excessive irrigation or rain

Source of calcium used as amendment to correct soil pH and add calcium.

Plant nutrients required in high quantities like Nitrogen, Phosphorous, Potassium.

Its partially decomposed plant material

Its value shows the degree of acidity or alkalinity. pH range between 0-14. Below 7 is acidic and greater than 7 is alkaline.
