Grass in farming is interconnected with livestock systems for their feed, in the form of grazing, haylage and silage, and is also used as 'leys' (short-term grasslands) to regenerate soil structure and quality.

Mob grazing is a form of intensive managed grazing where large numbers of animals graze a small area of land for a short period of time. There is increasing interest in this system due to perceived productivity and environmental benefits. However, there is very limited research to quantify the impact of mob grazing systems, and many farmers adopting the system have been influenced by anecdotal evidence from other farmers.

Some symbiotic or free-living microorganisms can fix inert di-nitrogen (N) from the air into reactive organic nitrogenous compounds.  Most biological N fixation (BNF) in farming systems occurs in the root nodules of legumes where rhizobium bacteria take photosynthates from the plant in exchange for fixing atmospheric N and returning ammonium or amides which the plant uses to form amino acids, proteins, etc.   Plants need more N than any other nutrient and N commonly limits plant growth in many ecosystems.
