• Landscape management A landscape is the evident factor of a land, its landforms, and the combined features of natural or artificial elements. Landscape management includes maintenance and integration of physical elements, water bodies, land cover, indigenous vegetation, human elements, such as structures and buildings, and climatic conditions. • Soil Preparation In the list of farming practices, soil preparation is placed second because of its importance for seed germination. Before a crop is grown, the soil is leveled and plowed a bit deeply to prepare it for the sowing of seed. After plowing, the soil loosens and develops proper aeration in the soil. • Sowing Seed selection from good quality varieties is the principal step of sowing. After preparing the soil, seeds are spread over the field, called sowing. Manual and mechanical (seeders) methods of sowing can be used. Some plants, such as rice, are first grown as seedlings in a small space and later transplanted to fields. • Manuring Plants need nutrients for their growth and fruit/seed production. Therefore, nutrients must be consumed at even intervals. Fertilization is the stage at which nutrients are introduced into the lands. These nutrients can be natural manure or artificial fertilizers. Decomposed products and waste of plants and animals are used as manure because of their nutrient richness. • Irrigation Irrigation means supplying water to plants. Water sources can be dams, ponds, wells, canals, etc. Excessive irrigation can damage crops and lead to waterlogging. The irrigation interval and frequency must be monitored, as they vary with the crop. • Weeding Unwanted plants grown alongside field crops are known as weeds. These plants are removed with the help of weed killers (weedicides), manually plucking with hands. Several weeds can be removed with better soil preparation techniques. • Integrated Pest Management • IPM – Integrated Pest Management, is a successful and ecologically sensitive technique to manage pests using combined sustainable practices. IPM is a series of methods including pest assessment, decision, and control techniques • Integrating Crops and Livestock Integrating crops and livestock increases the diversity and environmental sustainability of both sectors. In the meantime, it will offer opportunities to increase overall agricultural production and profitability. • Storage/Selling In the end steps of agricultural practices, the resulting grains are stored in warehouses for later use and selling purposes. Therefore, better plant protection methods must be used to protect grains from rodents and insect pests. The stores should be cleaned, dried, well-fumigated, etc., before storing grains. • Harvesting Among steps of farming practices, harvesting needs significant care otherwise it will result in yield reduction. When the crop reaches maturity, the cutting starts, and the produce will be stored in a dry place. This process is known as harvesting. After harvesting, manual or mechanical thrashing is done to separate grains from the plants.
