Clonal research takes years and money

  • May 15th, 2010

UC staff member Jorge Osorio Aguilar weighs grapes from a Syrah clonal selection under test for San Joaquin Valley conditions.

To a grower, the right wine grape clone can improve yield, advance or delay ripening, and reduce susceptibility to rots. For a winemaker, the right clone can add complexity to [...]

Grape clones: Learn by doing

Compost tea recipes

  • May 1st, 2010

Tweaking the aeration time, handling, and changing additives can create diverse compost teas—even though they were made with the same compost. Washington State University researchers saw differences in the microbial organisms, nutrients, pH levels, and salt concentrations of compost teas that all started from the same compost and water.
