Lipid-Extracted Algae as a Soil Amendment Can Increase Soil Salinization and Reduce Forage Growth

Alum Sludge as a Soil Amendment: Effects on Soil Properties and Plant Growth

Improving Soil Physical Indicators by Soil Amendment to a Saline-Sodic Soil

The application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. In this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. The five treatments were control (withoutamendment), municipal solid waste compost (MC), vermicompost...

Ruminant Nutrition Symposium: The utility of lipid extracted algae as a protein source in forage or starch-based ruminant diets.

Two experiments were conducted to determine the influence of lipid extracted algae (LEA) on OM digestibility, N flow, and rumen fermentation. Six samples of LEA were evaluated representing 2 genus of microalgae (Nannochloropsis spp. [n = 3] or Chlorella spp. [n = 3]). Four dual-flow continuous flow fermenters (2,700 mL) were used in a Latin square design to evaluate LEA in forage or concentrate...

Utilization of vinasses as soil amendment: consequences and perspectives

Vinasses are a residual liquid generated after the production of beverages, such as mezcal and tequila, from agave (Agave L.), sugarcane (Saccharum officinarum L.) or sugar beet (Beta vulgaris L.). These effluents have specific characteristics such as an acidic pH (from 3.9 to 5.1), a high chemical oxygen demand (50,000-95,000 mg L(-1)) and biological oxygen demand content (18,900-78,300 mg L(-...

Acid-Soil Resistance of Forage Legumes as Assessed by a Soil-on-Agar Method

plants, some white clover plants survived for 2 to 3 yr at a pH as low as 4.2 (Voigt, unpublished data, 1996). Establishment of small-seeded legumes on strongly acid soils can Thus, acid-soil resistance at seedlings stages may be even be even more difficult than maintaining those stands once established. more critical than acid-soil resistance at older stages of Our objectives were to use a soi...
