Relationships between ericaceous vegetation and soil nutrient status in a post-fire Kalmia angustifolia-black spruce chronosequence
Abstract Post-fire nutrient flushes are an important precursor to secondary succession in fire-driven boreal forest. We studied the magnitude of changes in post-fire soil nutrient status across a chronosequence of ericaceous shrub-dominated boreal forest stands in eastern Newfoundland, Canada. The chronosequence comprised nine stands burned between 1 and 38 years prior to the study. These ...

Are endophyte-mediated effects on herbivores conditional on soil nutrients?
Neotyphodium endophytes are assumed to have mutualistic relationship with their grass hosts, mainly resulting from mycotoxin production increasing plant resistance to herbivores by the fungus that subsists on the plant. To study importance of often ignored environmental effects on these associations, we performed a greenhouse experiment to examine the significance of endophyte infection and ...

Nutrient sorption dynamics of resin membranes and resin bags in a tropical forest
Plant root simulator (PRS) probes, a resin membrane technology, are increasingly used to measure soil nutrient availability in agricultural and nonagricultural systems. Like other resin technologies, the charged surface is meant to sorb nutrients until saturation; however, there is evidence that it acts as a dynamic exchanger in soils with low nutrient availability. This study compared the ...

Enhancing phosphorus phytoremedation potential of two warm-season perennial grasses with nitrogen fertilization
Phytoremediation or use of plants to extract soil nutrients is a practice used to ameliorate the impacts of excessive soil nutrients. Pensacola bahiagrass (Paspalum notatum Flügge) and ‘Floralta’ limpograss [Hemarthria altissima (Poir.) Stapf & Hubb] were grown in a P-impacted Immokalee fine sand (Mehlich-1 P 30 mg P kg–1) to evaluate increasing N levels on dry matter yield (DMY), forage P ...

Broiler litter fertilization and cropping system impacts on soil properties
Understanding the effects of management practices on soil properties is necessary because soil properties are directly related to the capacity of soil to function. Soil physical, chemical and biological properties were determined after 3 yr in three cropping sequences [continuous cotton (Gossypium hirsutum L.) (CCC), cotton-corn (Zea mays L.)-cotton (CMC), and corn-cotton-cotton (MCC) each at ...

A new method of poultry litter application to perennial pasture: Subsurface banding
Recently, incorporation of poultry litter by subsurface band application into pasture has been shown to reduce surface runoff transport of nutrients; however, data to evaluate the impact of this potential management strategy on forage production, forage nutrient concentrations, or the accumulation of soil nutrients after multiyear applications is limited. Therefore, two experiments, one in ...

Using Soil NPK Sensors to Improve Plant Nutrition
Introduction Plant nutrition is a critical aspect of sustainable agriculture, as it directly impacts the growth, development, and yield of crops. Traditional methods of fertilizer application often lead to over- or under-fertilization, resulting in poor plant growth or environmental pollution. With the advent of soil NPK sensors, however, farmers now have a precise and efficient tool to improve ...

Effect of exo-polysaccharides producing bacterial inoculation on growth of roots of wheat (Triticum aestivum L.) plants grown in a salt-affected soil
Abstract: Effect of soil salinity on physico-chemical and biological properties renders the salt-affected soils unsuitable for soil microbial processes and growth of the crop plants. Soil aggregation around roots of the plants is a function of the bacterial exo-polysaccharides (EPS), however, such a role of the EPS-producing bacteria in the saline environments has rarely been investigated. Pot ...

Nutrient status in Alpine soils of the Colorado front range using the Nitrogen/Phosphorus ratio index
The suitability of the foliar N/P ratio was evaluated as a predictor of nutrient limitation in an alpine ecosystem of the Colorado Front Range. We hypothesized that foliar N/P ratios are directly correlated with the alpine soil nutrient status. We used a long-term fertilization experiment conducted in three alpine plant communities, where 48 plots were established consisting of four replicates of ...

Soil Nutrients and Field Health: what you Need to Know
The soil on your field is like the brain to your body. It tells your crops everything they need to know to produce a healthy yield; how many organisms live there, what the pH balance is, whether or not something is performing well… For the brain, if something isn’t performing well, the body can react catastrophically. The same thing happens with soil. If you have too much ...
