Resources and their types

RESOURCES

 Anything that satisfies human need is known as resource. resources may not have their economic values such as water but they must satisfy human needs.

 TYPES OF RESOURCES

  Resources are mainly classified into two groups natural resource and human resource.
   Resources that are drawn from nature and used without much modification are called natural resources. for example air water ect.
    Natural resources are classified into different groups depending upon their level of development and use,origin, stock and distribution.
     On the basis of their development resources are classified into actual resources and potential resources.

     ACTUAL RESOURCES are those whose quantity is known and are used by us now-a-days.

     POTENTIAL RESOURCE are those who's quantity is unknown and are not used by us like sunlight in Rajasthan.

      On the basis of origin resources can be classified into abiotic and biotic. abiotic contains nonliving things by biotic contains living things.
       On the basis of their distribution resources can be classified into ubiquitous and localised.

        Ubiquitous resources are found everywhere like air we breathe water sector.

          Localised resources are those which are found only in a  particular part of Earth.. 

          NON RENEWABLE AND RENEWABLE RESOURCE
            resources which can be used by again and again are known as renewable resources like air water soil resources which we can use only one time in are known as  non renewable resources like Coal Petroleum.
            HUMAN MADE RESOURCES
             resources made by human are known as human made resources like  chair bulb etc as they satisfy our need.
        CONSERVATION OF RESOURCES
            conservation of resources is very important for us  because many non renewable resources take  a lot of time to be replenished.
            SUSTINABLE DEVELOPMENT
             balancing the need  to use resources and also conserve them for the future is called sustainable development.

Crop production and management

We all know that energy from food is utilised by organisms for carrying out their various body functions. We get our food from plants and animals. in this content we will read about how we get food from plants.

               CROP PRODUCTION AND                         MANAGEMENT

           When plants of same kind are grown and cultivated at one place on a large scale is known as crop.
            There are mainly two types of crops.

            Rabi crops- The crops which are grown in winter season are called Rabi crops for example wheat gram pea mustard etc.

             Kharif crops-The crops which are grown in rainy season are called kharif crops for example paddy cotton soyabean etc.

              Cultivation of crops involves several activities undertaken by farmers over a period of time known as agricultural practice.

               These agricultural practices are listed below-

               1.Preparation of soil
               2.Sowing
               3.Adding manure and fertilizers
               4.Irrigation
               5.Protection from weeds
               6.Harvesting
               7.Storage

                  Preparation of soil

                 The preparation of soil is the first step before growing a crop.One of the most important task in agriculture is to turn the soil and loose and it.This allows the roots to pendrate deep into the soil and breathe.

                           Sowing

                 The process of sowing seeds to produce crop is known as sowing.   Sowing is the most important part of crop production. Before sowing good quality of seeds are selected.

                 Adding manure and                                        fertilisers 

                  The substances which are added to the soil in the form of nutrients for the healthy growth of plants are called manure and fertilizers. soil supplies a lot of mineral nutrients to the crops which are very important for them. and when because of continuous growing of crops is done the soil become infertile
                  So fertilisers and manures are added.

                          Irrigation

                   Supplying of water to crops at definit time  interval is called irrigation.All living beings need water to live.Water is important for proper growth and development of flowers fruits and seeds of plants water is absorbed by plants roots.Along with water and Minerals and fertilizers are also observed.

                    Removal of weeds

                 Along with crops many undesirable plants are sober these plants are known as weeds.It is very important to remove weeds from farm because they also absorb the manure  fertilizers water which are given to plants and decrease their yeild.

                          Harvesting 

                     The cutting of Crop after it is mature is called harvesting.In harvesting crops are pulled out or get close to the ground. Harvesting is either done manually or stickle or by machine called harvester.

                                Storage

                      Storage of produce is an important task.If the crop grains are to be kept for longer time they should be safe from moisture insects rats and microorganisms.Before storing them the grains are properly dried in the sun to reduce the moisture this prevents the attack of insect pests bacteria and fungi.

                      THESE ALL AGRICULTURAL PRACTICIES SHOULD BE DONE IN AN MANAGED ORDER.SO,CROP PRODUCTION IS CALLED CROP PRODUCTION AND MANAGEMENT.
