Complexity in Rayleigh-Bénard Convection affect crop water requirements and thus the kinds of soil and water management practices. Thus a region with annual rainfall of 750 mm with good monthly distribution in a cool climate might utilize rain-fed agriculture-type management systems, whereas in a hot climate a region with poorly distribut作者: Implicit 時間: 2025-3-22 14:17

Although animal wastes, nonsymbiotic fixation, and atmospheric deposition can be significant sources of N, a large fraction of the first can be traced to legume sources and the latter two are generally insufficient to maintain productivity of cropland.

Complexity in Rayleigh-Bénard Convectioncrop production. Much of this land is best described as dryland. It is important to distinguish between dryland agriculture in particular and rain-fed agriculture in general. Clearly, they both exclude irrigation. The emphasis for rain-fed agriculture, however, is often on disposal of excess water, 作者: 不幸的人 時間: 2025-3-24 06:50

From 1950 to 1973, grain production increased 3. 1% annually, but slowed to about 2% from 1973 to 1984.

Modeling of Flow, Transport, and Crop Yield in Spatially Variable Fields,—field scale, to large—scale fields. Applications of such models to actual field conditions were supported by the assumption that the field can be regarded as a homogeneous or equivalent-to-homogeneous medium characterized by equivalent or effective soil properties that, in turn, are measured by sam作者: SIT 時間: 2025-3-25 20:51
