WAEC Agricultural Science 1988 Theory question 101

Any eight, each named and briefly explained:
Land tenure/land shortage: fragmented holdings and insecure ownership prevent large farms
Lack of finance/credit: farmers lack collateral and interest rates are high
Inadequate or costly farm inputs: improved seeds, fertilizers, agrochemicals are scarce or late
Poor storage and processing facilities: heavy post-harvest losses
Poor transport and road network: produce cannot reach markets cheaply
Poor marketing system: unstable prices, exploitation by middlemen
Illiteracy and inadequate extension services: slow adoption of new methods
Low level of mechanisation: drudgery limits the area farmed
Pests and diseases: reduce yield and quality
Lack of rural amenities: rural–urban drift reduces farm labour
Inconsistent government policies and unfavourable weather

Name the factor, then give one sentence on how it holds back large-scale farming.
