What is agriculture?
Agriculture can be defined as the science of rearing animals and growing crops to meet the demands of humans.
What is the purpose of levelling the soil after ploughing?
What is the purpose of levelling the soil after ploughing?
Levelling crushes large lumps of soil and reduces the chances of soil erosion.
Why are some crop plants like tomatoes, rice, and onions planted in nurseries?
Why are some crop plants like tomatoes, rice, and onions planted in nurseries?
These plants are planted in seed beds called nurseries to allow them to develop into seedlings before being transplanted to the field.

Study Notes
What is Agriculture?
- Agriculture is the practice of cultivating land, raising crops, and rearing livestock to produce food and other products.
Soil Preparation
- Levelling the soil after ploughing ensures even distribution of water and nutrients, and prevents erosion.
- It also helps to remove any obstacles that may hinder seed germination and growth.
Crop Planting
- Some crop plants like tomatoes, rice, and onions are planted in nurseries to allow for better growth and development before being transplanted to the field.
- This method helps to reduce transplant shock and promotes healthy establishment.
Agriculture Focus
- The main focuses of agriculture are to produce food, fibre, and other products, while also conserving natural resources and protecting the environment.
Soil Erosion Prevention
- Soil erosion can be minimized during the agricultural process through techniques such as contour farming, terracing, and cover cropping.
- These methods help to reduce soil runoff, retain soil moisture, and promote soil health.
Irrigation Methods
- Drip irrigation is not used by all farmers due to its high initial cost, although it is a water-efficient method that delivers water directly to the roots of the plants.
- Alternative irrigation methods, such as sprinkler and flood irrigation, may be more feasible for some farmers.
Crop Storage
- Failing to dry crops before storing them can lead to spoilage, mold growth, and pest infestations.
- Proper drying and storage techniques are essential to maintain crop quality and prevent losses.
Agriculture Science
- An agriculture scientist can help a farmer by developing a breeding program to combine the desirable traits of the two varieties of wheat, such as good yield and disease resistance.
- This can be achieved through cross-pollination and selection of offspring with the desired characteristics.
Soil Microorganisms
- Nitrifying bacteria in the soil are responsible for converting ammonia into nitrate, making it available to plants.
- Nitrogen fixation is the process by which certain microorganisms convert atmospheric nitrogen into a form usable by plants.
- Nitrogen fixation is important because it provides a natural source of nitrogen for plants, reducing the need for synthetic fertilizers.
