But why should not the New Englander try new adventures, and not lay so much stress on his grain, his potato and grass crop
, and his orchards -- raise other crops than these?
For four years, the three farming systems tested have been permanent pasture which uses fertiliser, a quasiorganic system which relies on natural nutrients such as manure, and a short-term lay system which sees farmers ploughing and sowing grass crops
"Perennial grass crops
that can be seasonally inundated, such as our mix of water foxtail, western mannagrass, and American sloughgrass, can handle some frost and should be drawn down as much as a month or more before the last frost," Rogers says.
Areas cultivated for a long period with grass crops
can still maintain a NNFB community capable of establishing symbiosis with the host leguminous plant in succession, i.e., an effect of resilience, also observed by Lima et al.
(2010) noted improved above ground biomass yields, with optimum C:N ratios resulting in moderate residue degradation as a result of biculturing legumes and grass crops
. Moderate residue degradation leads to moderate biomass persistence and mineralization rates translating to weed control and soil nutrient availability for longer periods (Ranells and Wagger, 1996; Clark et al., 1997; Teasdale et al., 2007).
She did her research on use of grass crops
for production of bio-ethanol as a sustainable energy resource.
Most of the research on yield response to N in dedicated bioenergy grass crops
has been done with warm-season grasses, and results have been highly variable, with some authors reporting no response and others reporting positive yield responses up to ~ 200 kg N [ha.sup.-1] (Wullschleger et al., 2010).
The land is vacant and has been used for growing grass crops
. It is zoned for agricultural use but is designated in Junction City's comprehensive plan for commercial development.
Mohammed Al-Ghashm, the head of Agricultural Services at the Ministry of Agriculture, said the locusts have damaged 90 percent of sesame, millet and grass crops
that are used to feed animals.
It is made from grass crops
such as corn, oats, or sorghum.
Gwyn Anthony of Haregrove Farm, Laleston, Bridgend, has piloted many schemes in farming including trials of cereal and grass crops
In fact these are sons of the soil combining deep into the night to gather in grain and grass crops
. And we should thank them.
