Effect of genotype and phosphorus fertilizer rates on water use and yield of chickpea
… aimed at evaluating the effect of genotype and phosphorus (P) fertilizer rates on water use and yield of four chickpea genotypes. A field experiment was undertaken, in winter 2009 and summer 2010, using a factorial arrangement of 3 P fertilizer rates (0, 45 and 90 kg P ha-1) and 4 chickpea …

Evaluation of the Feasibility of Struvite Precipitation from Domestic Wastewater as an Alternative Phosphorus Fertilizer Resource
… ore is the single global source material for phosphorus fertilizer production. Once these reserves are gone, agricultural production will be negatively impacted. There are currently no alternative phosphorus resources. However, phosphorus concentrations present in human excrement traveling …

The Effects of Nitrogen and Phosphorus Fertilizer on a Young Loblolly Pine Plantation on Lignite Mine Spoil in East Texas
<p>Five levels of nitrogen fertilizer combined with three levels of phosphorus fertilizer were tested in a two year-old loblolly pine plantation on a lignite mine spoil in East Texas. Growth parameters, foliar and spoil nitrogen and phosphorus concentrations were measured after two growing seasons. …

The effect of phosphorus fertilizer and bradyrhizobium innoculation on grain yield and nutrients accumulation in two chickpea (Cicer aritienum L.) genotypes
… of this study was to evaluate the effect of P fertilizer rates and rhizobial inoculation on yield and nutrients accumulation in two chickpea genotypes. Field experiments were conducted in winter 2017 and 2018 at University of Venda, Thohoyandou and University of Limpopo’s experiment farm, …

The response of symbiotic performance, growth and yield of chickpea (Cicer arietinum L. ) genotypes to phosphorus fertilizer rates and rhizobial inoculation
… Small-scale farmer’s flounder to afford Nfertilizers, coupled with the challenges faced by programmes aimed at assisting them about soil fertility in their cropping fields that are still without enough N concentration to meet N demand. It is therefore important that other alternatives that …

The fate of applied phosphorus on a piedmont soil and its effect on loblolly pine growth twenty years after application
A loblolly pine phosphorus fertilization trial was evaluated 20 years after establishment on a Tatum silt loam in the Virginia Piedmont. Triple superphosphate (TSP) was applied at 160 kg P/ha and ground rock phosphate (GRP) was applied at both 160 kg P/ha and 670 kg P/ha. Lime (4.48 T/ha) was …

Evaluating diagnostic tools for phosphorus and sulfur management in corn
… management of essential nutrients, such as phosphorus (P) and sulfur (S), is critical for maximizing corn productivity. This study aimed at enhancing corn production by evaluating diagnostic tools for nutrient management and optimizing fertilization practices, focusing on P and S nutrients. …

Struvite Recovery From Source-Separated Urine Utilizing Fluidized Bed Technology
… management, water conservation, and an impending phosphorus fertilizer shortage. Municipal wastewater systems are designed to treat the combination of urine, feces and graywater produced in household applications. Urine accounts for 1% of wastewater by volume, but provides 70-90% of nitrogen, …

Quantifying nutrient cycling and fate within an abandoned feedlot and adjacent wetlands
… and groundwater beneath abandoned feedlots, but phosphorus can cause both short- and long term contamination, especially in well-drained carbonate and iron-rich soils associated with Concentrated Animal Feeding Operations. It is also hypothesized that a spectral vegetation index can be used as an …

Functional and community investigation of nodule endophytes for the selection of phosphate solubilizing rhizobial inoculants for clover : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University
Nitrogen (N) and phosphorus (P) are limiting nutrients for plant growth and are the largest fertilizer inputs in agriculture. Phosphorus fertilizer has a low efficiency of use with only 5-30% utilized by the plant, the rest forming metal complexes and becoming unavailable to plants. In New Zealand, …

Optimizing nutrient availability for high-yield corn production
With increased fertilizer cost and the potential for increased environmental regulations in states like Illinois, many producers are interested in increasing the availability and effectiveness of their fertilizer applications. Elevated yield levels of modern hybrids require higher amounts of …
