2.1 Short description of the Technology

Definition of the Technology:

Improving fertility of saline soil applying combination of organic and inorganic fertilizers

2.2 Detailed description of the Technology

Description:

The total area where the technology implemented is 70 feddan. the farm is 35 years since it is established. there are also 4 green houses. There are 2 pumps for pumping irrigation. organic and inorganic fertilizers are used in this farm. crops grown are leafy crops.(onion, alfalfa, Rhodes Grass, Lemon , Date Palm, cassava)

Purpose of the Technology: to improve the productivity of soils under saline conditions . Salinity level of irrigated water is about 2.24 dS/m.

Establishment / maintenance activities and inputs: Land preparation is done before planting by plowing and harrowing. then the fertilizer applied before planting. Crops are cultivated by special machinery. The crops are also weeded manually.

Natural / human environment: the technology is implemented in nearly level land. Irrigation water is from wells. the farm is situated in locality where similar small holding are found in the surroundings.
