SOIL DEGRADATION & CONSERVATION
SOIL CONDITIONING
EXAMPLE OF CONDITIONERS : ORGANIC MATERIALS & LIME
WHEN THERE IS ACIDIC SOIL,, WE NEED TO ADD ON ALKALINE SUBSTANCE TO INCREASE THE PH OF THE SOIL
PLANT NUTRIENTS, BACTERIAL ACTIVITY (DECOMPOSITION)
WATER IRRIGATION
SALINIZATION
ALKALINAZATION
CHALK STONE PLANTING TO REDUCE ALKALINIZATION
GULLYING
CAUSE EROSION OF SOIL AT THE HILL SIDE
USE TERRACE METHOD
COMPOSTING
HIGH WATER RETENTION
WATER IS EASIER TO RUNN OFF THAT INCREASE ERROISION
WINDBREAKS
EX: MONGOLIA
REDUCE GRASSLAND DUE TO LIVESTOCK FARMING
BY PLANTING MRE TREES IT CAN REDUCE WIND BLOW
REDUCE ERROSION OF TOP SOIL
TERRACING
EX: BALI, CAMERON HIGHLANDS
STEPS REDUCE WATER RUN OFF COMEING FROM THE SOPE
CONTOUR PLOUGHING
RIDGE AND FURROW MUST BE PERPENDICULAR TO THE WATER FLOW
STRIP CULTIVATION
PLANT WITH DIFFERENT SPECIES
MONOCULTURE REDUCE SOIL FERTILITY
SOIL MOISTURE AVAILABLE
INCREASE BIODIVERSITY
AVOID USING MARGINAL LAND
HAS LITTLE OR NO IND=USTRIAL VALUE
POOR WATER SUPPLY, SOIL QUALITY, TERRAIN CHALLENGES
FINANCIAL PROBLEMS IN GROWING MARGINAL LAND
NAK TAK NAK KENA JUGA JUGA TO HELP AID WORLD HUNGER
