Productivity, Carbon Sequestration, Nutrient Accumulation, And Species Interactions In Perennial Biomass Alley Cropping Systems
… the potential for biomass feedstock production, nutrient uptake and accumulation, and carbon sequestration in alley cropping agroforestry systems at two Minnesota sites, and to determine how tree – crop interactions influenced productivity in these systems. Short-rotation woody crops (SRWC) were …

Floating Treatment Wetland Nutrient Uptake Efficiency on the Salmon River
… a potential nature-based solution for removing nutrients and other contaminants, yet their effectiveness in the natural environment is uncertain. This study evaluated FTW efficacy on the Salmon River, BC, where downstream algal blooms persist in Shuswap Lake, using three native macrophytes …

The ecophysiological significance of insectivory as well as nitrogen and phosphorus availability to sundew nutrient cycling, growth, and success
The impact of nutrient addition on growth and nutrient accumulation in insectivorous plants was studied in field populations and greenhouse plantings. Drosera rotundifolia was studied in the field, and D. binata var. multifida and D. capensis were studied in long-established plantings in the …

Residual Nutrient Removal by a Winter Cover Crop From Broiler Litter Amended Soils
… concerns. One primary concerns is the possible nutrient build-up in pasture and cropland as a result of broiler litter application. Studies were conducted at Western Kentucky University using sorghum sudangrass (Sorghum bicolor (L.) Moench) as a forage to possibly remove excess nutrients. This …

Strip-till and no-till soybean growth and distribution of roots and soil phosphorus, potassium, and water with broadcast and subsurface-band fertilization
Method of application of the slowly-mobile nutrients phosphorus (P) and potassium (K) in conservation tillage systems were little mixing of the soil occurs, is an important management decision as placement can influence the availability to these nutrients to the crop. The objectives of this study …

Ecological influences in the biogeography of the Austral sedges
… of the tribe also suggests a preference for low-nutrient soils, which I investigate at the local (microhabitat) scale by contrasting the distributions of the tribes Schoeneae and Cypereae on the Cape Peninsula along soil fertility axes. The relationships between the phenotypic traits of species …

Properties and Potentials of Coal Mine Soils in Southwest Virginia 29 Years After Establishment
… coal region seeks to measure carbon (C) and nutrient accumulation and retention under forest vegetation to better understand the role of reforestation in the re-establishment of these ecosystem services. This study capitalized on the Controlled Overburden Placement Experiment (COPE), a …

Cultivating Sustainability: Analyzing Soil Health Dynamics and Economics of Cover Crops in the Mid-Atlantic
… role in optimizing biomass production and nutrient accumulation. Overall accumulation rates were 44.4 kg dry biomass ha-1 d-1, 1.22 kg N ha-1 d-1, 0.16 kg P ha-1 d-1, 1.36 kg K ha-1 d-1, and 0.08 kg S ha-1 d-1 of delayed termination between March 15 and April 30. Each additional day of …

Overhead sprinkler irrigation strategies to reduce water and nitrogen loss from container-grown plants
… irrigation did not result in substrate nutrient accumulation and had no adverse effect on plant growth. Fresh and dry root weights and shoot and root N concentrations were greater with intermittent irrigation than continuous irrigation.

SIMULATED MINE LAND RECLAMATION IMPACT ON BIOMASS PARTITIONING AND NUTRIENT CONTENTS IN LOBLOLLY PINE
… and analyzed to determine dry biomass and nutrient (N, P, K, Ca, Mg) contents for the three treatments. Allometric equations relating dry weights of foliage, stem, branches and roots to diameter at groundline and height were developed to estimate tree biomass. Estimated biomass accumulation …

Nutrient uptake and partitioning in high-yielding corn
… aimed at matching plant nutritional needs with nutrients from soil and fertilizer sources. These practices, when done sustainably, also include replacing removed nutrients through maintenance fertilizer applications without excess application rates. While fertilizer recommendations and nutrient …

Functional role of plant water fluxes in nutrient acquisition
… it may also function to cool leaves, transport nutrients and drive nutrient acquisition via mass-flow. In addition to transpiration, plants water fluxes occur through hydraulic redistribution (HR). I hypothesized that an important function of plant water fluxes is to drive mass-flow nutrient …

Agronomic and nutritional considerations for increased soybean productivity
… productivity. The synergy between adequate nutrient availability in combination with complementary agronomic practices, may be necessary to realize the genetic yield potential of soybean. For these reasons, the objective of this research was to quantify how agronomic and nutritional …

Polyhalite alters the uptake and partitioning of mineral nutrients in corn
… of crop nutrition. Polyhalite is a multi-nutrient fertilizer that supplies four key plant nutrients potassium, calcium, magnesium, and sulfur. Sirius Minerals, a company formed to develop and market the new fertilizer, has started to commercially produce a granulated version of polyhalite …

The costs and benefits of hosting colonial sociable weaver nests for arid zone savanna trees
… ecosystem is water and, in some instances, nutrient-limited, creating competition among species. Species, however, coexist in this ecosystem through processing like facilitation acting together with competition. Facilitation is an ecological interaction in which one species enhances the …
