Explanation

(a)Farm mechanisation is the application of engineering principles and technology in agricultural production, storage rnd processing on the farm. It is applicable to land preparation, planting, fertilizer application, weeding and crop  harvesting, rearing, care and feeding of animals as well as processing and storage of farm produce using appropriate farm machinery.

b)(i) The advantages of farm mechanization are:

(1) It increases production of large quantity of food;

(2) The yield is maximised by using more efficient farm operators;

(3) Farm labour output per man hour is increased;

(4) Timelines of operations is enhanced;

(5) Elimination or minimization of human drudgery in form of work;

(6) increases the revenue base of farmers;

(7) Large acreage/hectarage of farms can be cultivated;

(8) accomplishes lots of work with less human labour;

(9) Certain farm operations can only be accomplished by mechanized devices;

(10) There is reduction in  the cost of agricultural operations per unit output;

(11) usually improves the quality of some farm produce e.g. rice processing;

(12) It releases labour to other sectors of the economy;

(13) It saves time and quickens operations;

(14 promotes specialization in farm operations.

(ii) Disadvantages of farm mechanization are:

(1) It causes damage crops if care is not taken;

(2) It can also cause injury of fruits during harvest and the injury can serve as a source infection;

(3) The machines are costly to purchase

(4)inadequate technical know -how on the use and handling of the machines and equipment;

(5) inadequate spare or replacement parts;

(6) high cost of maintenance of machines

(7) It aids the spread of pests and diseases through contaminated machines;

(8) It does not need human labour to control it

(9) This can lead to unemployment;

(10) reliance on fuel whose supply is not always stable;

(11) It can lead to environmental pollution;

(12) leads to soil compaction and destruction of soil structure.
