Planting geometries and the efficient use of water and nutrients

摘要: In nature and in the most primitive agricultural systems, seed distribution is broadcast across landscape. Such a distribution results nearly uniform spacial interaction of developing phytomass. With development of agrarian civilization has come an implement-dependent systemization crop- planting patterns. This brought about planting crops uniform rows—from drilling small grains at inter-row spacings 0.1 to 0.2 m plant intra-row i 5 cm, staking horticultural and vine 2- 3—m typically 0.3- l-m spacings. The implement dependence cropping strategies has resulted row cropping. The staple regarded as suited this approach are commonly called crops, this review will concentrate largely on how interact with geometry, water, nutrients to in?uence sustained productive capacity.
