Description Cattle Pigs Poultry Young from birth /hatching to warning Calf Piglet Chick Young female before first parturition /laying Heifer Gilt Pullet Mature male for breeding Bull Boar Cock - What is nitrogen cycle? (1mk)
- It is a series of changes which nitrogen undergoes between the atmosphere, water, soil and living organisms.
- State two types of sampling methods. (2mks)
- Traverse method
- Zigzag method
- State four reasons for applying phosphatic fertilizes. (2mks)
- Root development
- Essential for flowering, fruits and seed formation.
- Play an important role in metabollic processes
- It is part nucleo-proteins which are required during cell division
- Strengthens plant stems, thus preventinig lodging.
- A farmer was advised to apply 150kg CAN/ha while top dressing the maize crop, CAN contains 21%N
Calculate the amount of nitrogen applied /ha. (2mks)
21kgN is contained in 100kg CAN
150kg CAN supplies
100kg CAN = 21kg N
150kg CAN = 21kgN × 150kgCAN
100kg CAN
= 31.5kgN/ha
