It involves a wide range of activities such as crop cultivation, livestock rearing, forestry, fishery, and related processes like harvesting, processing, and marketing of agricultural products..

Manure refers to organic matter, primarily animal feces, that is used as a fertilizer in agricultural practices. It is a valuable source of nutrients and organic material that can enhance soil fertility and improve crop growth. Manure can come from various livestock animals, including cattle, pigs, horses, poultry, and sheep.

Weeding refers to the process of removing unwanted plants, commonly known as weeds, from agricultural fields, gardens, or other areas where they can compete with desired crops or plants. Weeds are plants that grow vigorously and often have the ability to outcompete cultivated plants for resources such as water, nutrients, light, and space.

Harvesting refers to the process of gathering mature crops or agricultural products from the field or their natural environment for consumption, sale, or further processing. It is the final stage in the agricultural cycle that involves removing the fully grown and ripened crops from their growing location. Harvesting is a crucial step in agriculture as it allows farmers to obtain the yield of their efforts and brings the products to market or for storage and subsequent use.
