Determined by:
Factors determining number of secondary cultivation:
Ridging; The process of digging soil on a continuous line and heaping on one side to produce a furrow and a bund (ridge). It is important for root crops, to allow root expansion and for soil and water conservation. Rolling: It is the compaction of the soil to produce a firm surface which increases seed-soil contact and prevents wind erosion. Levelling; Production of an even, uniform surface which promotes uniform planting. Sub soiling: This is deep cultivation into the subsoil layer to break up any hardpan which might have developed. It is done for the following reasons:-
Minimum Tillage:
This is the application of a combination of farming practices with the aim of reducing the disturbance of the soil.

FARM TOOLS AND EQUIPMENT (7 LESSONS)Introduction to Farm Tools and Equipment
Farm tools and equipment perform specific jobs in the farm.
They make work easier and more efficient. They can be classified according to their uses as follows: Garden Tools and Equipment
Panga
Cutting and shallow cultivation, making holes. Jembe / hand hoe Cultivation, digging, shallow planting holes and trenches. Fork Jembe Cultivation, digging out roots, harvesting of root crops. Rake Collecting trash, breaking large clods, levelling, removing stones from a seedbed and spreading organic manure. Spade Scooping and carrying of soil, sand, concrete mixture and manure. Spring balance Measuring weight. Trowel Scooping seedlings during transplanting and digging planting holes for seedlings. Pruning hook Bending tall branches when pruning. Secateur Cutting young stems and pruning branches. Tape measure Measuring distances. Axe Cutting big trees and roots and splitting logs of wood. Soil auger Making holes for fencing posts.
