Soil Fertility Vs Soil Productivity
|
Soil Fertility |
Soil Productivity |
|
Soil fertility is the status or the inherent capacity
of the soil to supply nutrients to plants in adequate amounts and in suitable
proportions |
Soil Productivity is the capacity of the soil
to produce crops with specific systems of management and is expressed in
terms of yield |
|
Soil fertility is the capacity of the soil to
produce crops of economic value and to maintain health of the soil without
deterioration |
|
|
Note: All productive soils are fertile, but
all fertile soils need not be productive due to some problems like water
logging, saline or alkaline condition, adverse climate etc. |

Weather Vs Climate
Definition of weather
- Modification of Weather, except to a limited extent, is difficult and uneconomical.
- Weather is a state or condition of atmosphere at a given place and at a given time
- Weather is daily variations or conditions of lower layers of atmosphere
- Weather pertains to smaller area like village, city, or even a district and smaller duration of time i.e, part of a day or complete day.
- Weather is expressed by numerical values of meteorological parameters.
- Example of weather are hot day, rainy day, cloudy weather, dry weather etc.,
Definition of Climate:
- Climate is generalized weather or summation of weather conditions over a given region during a comparatively longer period.
- Climate is weather condition related to larger areas like zone, state, country, part of continent or whole of continent, longer duration of time like month, season or year.
- Climate is expressed by normals and averages e.g., cold season, tropical climate etc.,
