A tomato crop (cv. Ramyle) was cultivated in coir crop units at the University of Almeria from November 2012 to May 2013.
A soil-based cropping unit fuelled with human urine for long-term manned space missions was investigated with the aim to analyze whether a closed-loop nutrient cycle from human liquid wastes was achievable.
Urine from the crew was used to supply primary (N, P, and K) and secondary (S, Ca and Mg) nutrients to wheat and soybean plants in the controlled cropping unit.
Net leaching of NO−3 solute, gaseous fluxes of NH3, CO2, N2O, NO and N2, depth concentrations of O2, CO2 and dissolved organic carbon (DOC), and pH in the root zone were calculated for a bioregenerative cropping unit under gravitational acceleration of Earth and for its homologous on Mars, but under 0.38g.
The Genetic Improvement of Fruit Crops unit provides genetic solutions to major problems affecting temperate tree fruit agriculture including orchard productivity, high labor costs, bloom-time related cold injury, consumer demand for superior fruit quality, as well as the need for new genetic engineering technologies to address emerging threats.
Success with the zinc finger could also give Dow AgroSciences, the crops unit of $54 billion (sales) Dow Chemical, the second-largest chemical company in the world, a bigger share in the global agbiotech boom.
In some adapids, the crests of the lower incisors and canines align to form functional cropping unit, and the American paleontologist Philip D. Gingerich has suggested this foreshadowed the development of the lemuriform toothcomb.
The two cropping units were treated with the same fertilizer type and rate, and with the same irrigation regime, but under different initial soil moisture content.
The cropping units are generally small.
Mosaic was formed in 2004 from the merger of Cargill's crop nutrition unit with IMC Global, creating a giant in fertilizer production and leaving Cargill with a 64 percent stake.
