Biochar is a carbon-rich solid made by heating biomass in a low-oxygen environment. It is used as a soil amendment, compost additive, filtration material, and carbon-storage product, but its effects depend strongly on feedstock, production conditions, soil, climate, and application rate.
Crop rotation is the practice of growing different crops on the same field in a planned sequence across seasons or years. Rotations can support soil health, disrupt pest and disease cycles, manage nutrients, spread labor, and reduce risk when they are matched to local climate, markets, and farm goals.
Companion planting is the practice of growing different plants near each other because their traits may help with space use, pest pressure, pollination, soil cover, nutrients, or harvest timing. Some pairings are strongly supported by horticultural research, while others are traditional or observational.
Controlled-environment agriculture uses structures and technology to manage crop conditions such as light, temperature, humidity, carbon dioxide, nutrients, and water. It includes high-tech greenhouses, vertical farms, growth chambers, hydroponics, aeroponics, and aquaponics.
