The Valmar acquisition adds significant benefits and expertise to Salford, with an expanded product line that now includes: primary, secondary, and vertical tillage, air seeders, commodity carts, cover crop
seeders, spinner-type fertilizer spreaders, air-boom applicators and granular applicators for fertilizer, insecticide, seed, seed inoculant and forage preservatives.
Almonds, for example, need a cover crop
that blooms when pollinators arrive on the farm, but fades thereafter so as not to compete for the insects' attention.
Conventional wisdom holds that grazing would remove the nitrogen and carbon otherwise left on the soil in the cover crop
At that point in its life-cycle, the root growth, nitrogen content and biomass of a fall-planted cover crop
reach their peaks.
For my purposes in this paper, I will use "cover crop
" to mean either or both: A cover crop
is a crop that we grow, not to use as food directly, but to protect, nurture, and "feed" the soil.
Conservation tillage systems plant the summer cash crops directly into a killed winter cover crop
with minimal or no tillage.
They cover crop
development and phenology, including case histories, the inception and use of solar radiation by the canopy, photosynthesis and photorespiration, the loss of carbon dioxide in respiration, the partitioning of dry matter to harvested organs, limiting factors and the achievement of high yields, the physiology of crop quality, the simulation modeling of groups (including models for wheat, soybeans and corn) and the future of crop physiology given climate change, lowering inputs, new crops and quality.
Under the Arable Area Payments Scheme land required for setaside must have in place a suitable cover crop
by January 15 (tomorrow) or late-harvested crop removed.
To further enrich the soil after the growing season ended in fall, they sowed a cover crop
of annual rye-grass and topped off the beds with a 3-inch layer of manure.
But all that tall, healthy cover crop
attracts lots of moles and gophers, who tunnel through the soil and love to eat tender young vine roots.
A cover crop
