Their failure to get established is usually due to the use of low-quality planting stock and adverse site conditions.
Milton argues that meat supplied early humans not only with all the essential amino acids, but also with many vitamins, minerals and other nutrients they required, allowing them to exploit marginal, low quality plant foods, like roots - foods that have few nutrients but lots of calories.
About three quarters of the world's agricultural land produces forage suitable for grazing by these ruminants, which have an astonishing capacity to efficiently convert low quality plant fibre that is often unsuitable for human use into energy dense fat, muscle and milk.
But as low-quality, poorly designed solar plants sprang up on Spain's plateaus, Spanish officials came to realize that they would have to subsidize many of them indefinitely, and that the industry they had created might never produce efficient green energy on its own.
Naturally produced and synthetic contraceptive pill estrogens may pass low-quality waste water processing plants and feminize male fish in streams and coastal areas downstream such discharges [ 1, 2].
In particular, many farmers had planted on low-quality lands, ignoring best-practice advice.
The burden of breathing of low-quality air near fossil-fuel power plants, as well as the various health costs of climate change, disproportionately falls on low-income people — both at home and abroad.
Designing a conventional plant to run on low-quality coal also costs more, but the increase is only 24 percent less than the 37 percent with IGCC.
But areas using low-quality coal could be better served by pulverized coal plants, especially the new ultra-supercritical coal plants that power turbines with very high temperature steam.
Association with multiple ant species may be risky for ant-plants because diffuse interactions with low-quality partners may result in reduced net fitness benefits compared to more specialized relationships with high-quality mutualists [61], [62].
Among them, 2,288,819 (7.52%) reads with significant homology to plant non-coding RNAs and 1,646,611 (5.41%) low-quality reads were firstly removed.
