 Selection of site

The site was selected because of the   soil type and the ph. range .it was also selected because the site is fenced so to keep away stray animals and entrance of thieves.it was also selected because of the water source.

Selection of crop

The crop was selected because of the soil type, ph. and demand, the soil type which is clayey loam and its ph. was 6.5, tomatoes grow well on such soil.

Lay out

Lay out was to get the required measurement of the beds.it was done using a measuring tape. The measuring tape was used to measure the length and width of the beds.

Land clearing

Land clearing was done to remove unwanted vegetation and objects from the plot. This was done manually using a cutlass and a hook stick. The cutlass was used to cut the weed on the beds .a hook stick was used to heap the weeds on the bed.

Ploughing

Ploughing was done to break up surface soil and to turn the topsoil to a desirable depth. Loosing up soil particles allow free movement of water, air and plant roots among soil particles.
