Soil Conversation

Definition

Soil conversation means protection, improvement and sustained renewal of the soil at any place.

Soil conversation is a set of management strategies for prevention of soil being eroded from the earth's surface or becoming chemically altered by overuse, acidification, salinization or other chemical soil combination.

Methods of Soil Conversation

Agronomic practices

Crop rotation : This refers to growing of two or more different crops in sequence in a field for maintaining the soil fertility.

Contour Farming : It involves preparation of the field with alternative furrows and ridges.

Terrace Cropping : Step can be cut out on the slopes making terrace.

Strip Cropping : This practice consists of growing erosion permitting crops (jowar,bajra,maize) in alternate strips with erosion checking close growing

crops (grass, pulse).

Multiple Cropping : The practice of growing two or more crops in the same space during a single growing season.

Shelter belts : Plantation usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil erosion.

Mechanical Methods :

Basin listing : Construction of small basin along the contour to retain water

Contour Terracing : Digging a channel along the slope to intercept and divert the runoff water.

Other Methods :

No-till Farming

Salinity Management

Soil Organism

Indigenous Crops

Plant Trees

Albugo

CLASSIFICATION KINGDOM : MYCOTA DIVISION : EUMYCOTA SUBDIVISION : MASTIGOMYCOTINA CLASS : OOMYCETES ORDER : PERENOSPORALES FAMILY : ALBUGINACEAE GENUS : ALBUGO DIAGNOSTIC CHARACTERS OF ALBUGO The genus Albugo or Cystopus is an obligate parasite on a number of flowering plant.
