Plants are productive from about latitudes 30N and 30c to near the equator. They have persisted in areas receiving rainfall as low as 750 mm per year but are probably best suited to areas receiving 1,000 - 2,000 mm[310 ]. Unlike many tropical legumes, it can compete successfully with sward-forming grasses[310 ]. It grows best when mean monthly temperatures are above about 20°c. Although tops are cut by frost, plants regrow vigorously with the onset of warmth and moisture[310 ]. During very dry conditions, top growth may die off, but rhizomes mostly survive, providing a nucleus for recovery[310 ]. Grows successfully on soils with textures ranging from sands to clays provided they are well-drained[310 ]. While apparently preferring acid soils, it has produced good yields on neutral to slightly alkaline soils[310 ]. It grows well on soils low in phosphorus[310 ] Grows well on infertile or fertile soils, but may suffer from excessive grass competition on the latter. Appears to be less P-demanding than A. pintoi .This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200 ]. When planting in new areas, it is generally not necessary to inoculate the rhizomes[310 ]. Four cultivars have been released in Florida: 'Arb', 'Arblick', 'Florigraze' and 'Arbrook'. 'Arb' and 'Arblick' were selected initially, based on productivity and spreading ability respectively; 'Florigraze' was selected because it combined both characteristics, and 'Arbrook', the most recent release, because it is more drought-tolerant than 'Florigraze' but is of similar productivity[310 ]. One accession known as the Maiwa peanut (probably the Australian accession CPI 12121) has persisted well in Indonesia[310 ].

Carbon Farming

• Agroforestry Services: Nitrogen  Plants that contribute to nitrogen fixation include the legume family – Fabaceae.
• Agroforestry Services: Understory legume  Legume vegetation, especially the trees and shrubs growing between the forest canopy and the forest floor.
• Management: Fodder  Non-destructive management systems maintaining the soil organic carbon.
• Management: Hay  Cut to the ground and harvested annually. Non-destructive management systems maintaining the soil organic carbon.
• Minor Global Crop  These crops are already grown or traded around the world, but on a smaller scale than the global perennial staple and industrial crops, The annual value of a minor global crop is under $1 billion US. Examples include shea, carob, Brazil nuts and fibers such as ramie and sisal.
