Abstract:
... The restoration of degraded grasslands can be achieved via multiple methods (e.g., increasing plant propagule input, improving site conditions, and enhancing soil resources); however, little is known about the relative roles of these methods. We conducted an experiment in Inner Mongolia (China) to address how plowing, seeding, and fertilizing influenced species diversity, functional groups, and co ...

Abstract:
... Switchgrass (Panicum virgatum) is a perennial grass highly valued as an energy crop resource for the production of bioethanol due to its high carbohydrate content, fast growth, and ability to grow in lands that cannot support crop or food production. In the present study, this biomass was submitted to steam explosion pretreatment in a semi-continuous pre-pilot reactor with the aim of obtaining a p ...

Abstract:
... Grazing dormant forage under low-input heifer development strategies typically exposes cattle to low-quality forage. Protein supplementation while grazing dormant range can enhance heifer growth and reproductive performance. We examined resource utilization of heifers and the effects of dormant season grazing on residual vegetation characteristics under two supplementation management strategies. A ...

Abstract:
... Perennial grasses can provide very high biomass yields and a better environmental profile compared to most annual cereal crops. The grass biomass can be processed into a protein-rich fraction for monogastric feed and a fibrous pulp fraction for ruminant feed or energy production. We studied the effect of fertilization of tall fescue grown on two sandy sites in Denmark. Dry matter (DM) and crude pr ...

Abstract:
... Winter cover crops (CCs) provide soil conservation benefits for strip-tillage tobacco producers, but soil-residual herbicides may interfere with their establishment and growth. Tobacco is planted later than many agronomic crops, but growers often terminate CCs early to minimize CC residue at planting, and this may reduce weed suppression potential. We examined residual herbicide effects on CCs acr ...

Abstract:
... In silvopastoral systems, the use of land for multiple purposes diversifies economic income and improves the stability of the system. If shading levels are medium or high, cattle production is often limited by the absence of one or more forage components of the herbaceous layer (such as perennial grasses). In the present study, we hypothesized that perennial C₃ cover is a major determinant of catt ...
