With proper management, they are capable of sustaining high yields.
These systems were the home of the Green Revolution in rice, and global food security will continue to depend upon their continued ability to sustain high yields.
Similarly, nutrient supply by oil-based cakes which is a form of organic manure will not only decrease the reliance on chemical fertilizers, but also develop the soil structure, boost the growth and activity of useful organisms in the soil, ease the deficiency of secondary and micronutrients, and sustain higher yield due to better soil health (Tiwari 2002; Singh et al. 2006).
Grazing is considered a normal behavior for dairy cattle, although they may not be able to meet their nutritional requirements from grazing alone, and so to sustain higher yields requires access to a total mixed ration (TMR).
Additionally, the loamy soils in the north sustain higher yields and vole abundances, permitting the increase in buzzard densities.
Unfortunately, this understanding does not include newer techniques for maintaining soil fertility to sustain higher yields or for averting losses to pest infestations.
One of the greatest challenges in today's agriculture is the need to adopt practices that protect environmental and ecological resources, minimize economic costs and promote social stability while sustaining high crop yields.
India, China and the United States rely on irrigation to sustain high crop yields but may be depleting groundwater faster than it can be replenished.
If the small plant were expanded to meet sustained high demand, it would yield $700,000 cash flow annually, and so would be less efficient than a large plant built initially.
Hence, the cultivation cost is lower as these crops can still sustain reasonably high yield without intensive care.
