Plants and population: Is there time? [PDF]
Proceedings of the National Academy of Sciences, 1999 The year 1998 was the 200th anniversary of the publication of Malthus’s famous first essay on population (1). Malthus argued that agriculture could not increase production as fast as the lust between the sexes would inevitably increase population size, and therefore that humans were condemned to poverty, famine, pestilence, and vice. Malthusian worries

Carrot Yield and Shape Altered by Seeding Rate and Raised Beds in Clay-loam Soil
HortScience, 2021 Carrots (Daucus carota L. var sativus) in the midwestern United States are generally raised commercially on sandy-loam or muck soils. Some smaller growers may not have the luxury of an ideal soil type, so raised beds are often recommended to improve ...
