CHAPTER 6 : SUSTAINABLE AGRICULTUR

DEFINE : Production of food, fiber, (plant/ animal ) using          

                    farming technique 

                  : Produce healthful food without compromising future                        generation ability to do the same

SUBSTAINABLE FARMING

• Organic farming
• Biodynamics
• Permaculture
• Low- input
• Agro-ecologocal system

THE FARM AS AN ECOSYSTEM

Will conserve oil and water resources and eventually reduce the overall operating cost if it function properly

 FOUR ECOSYSTEM PROCESS

Energy flow

Energy flow - is the non- cyclical path of solar energy (sunlight) going into and through any biological system

Water cycle

Water cycle - is typified by little soil erosion, fast water entry into the soil, and a capacity of the soil to store large amount of water

Mineral cycle

Mineral cycle - involves the movement of nutrient from the soil through the crop and animal and back to the soil thus reducing the need for fertilizer and feed.

Ecosystem dynamic

Ecosystem dynamic - is indicated by high diversity of plants and animal both above and below ground.

SUSTAINABLE PRACTICE

CONSERVE OIL

Ø COVER CROPS, MINIMIZE TILLAGE, CROP ROTATION

RECYCLE NUTRIENT

Ø COMPOST, MANURE, CROP RESIDUES  

PLANNING AND DECISION MAKING

        •Technology driven
•Increased level of investment in physical capital
•Priority to cash crops 
•Priority to irrigated areas

FARM AND DEVELOPMENT                 APPROACH

        •Priority to rained areas

        •People's participation oriented

•Greater investment in human resource and capacity building

•Priority to food security
