Urea fertilizer placement effects on soil greenhouse gas emissions and corn growth
… of this research was to investigate the impact N fertilizer placement has on GHG emissions and corn growth. The specific research objectives were to determine the effects of urea fertilizer placement with and without a nitrification inhibitor (NI) on cumulative soil GHG emissions (N₂O and CO₂) and …

Flow and transport processes as affected by tillage management under monsoonal conditions in South Korea
… tillage (CT). In a flat terrain, N fate under fertilizer rates at 50, 150, 250 and 350 kg NO3− ha−1 was investigated in a plastic mulched radish field using suction lysimeters, tensiometers and a 15N tracer experiment. We used datasets of nitrate concentrations and matric potentials to …

Enhanced efficiency phosphorus application for corn
… in the use of enhanced efficiency phosphorus (P) fertilizer applications or treatments. The objectives of this research are (1) to determine the effects of tillage/fertilizer placement [no-till (NT)/surface broadcast or strip-till (ST)/deep banding], monoammonium phosphate rate [0, half the …

Improved agronomic management of corn and soybean to increase productivity
… To combat higher nutrient demands, innovative fertilizer sources as well as advanced application technologies are being developed that could potentially help to drive the continual increase in yields. Hence, the objective of this research was to evaluate some fertilizer source and application …

Impacts and correction of potassium deficiency in no-till and strip-till soybean and corn production
… are impacting soybean yields, and if so, what fertilizer application practices including: rate of K application; broadcast or deep band methods of application; and the use of starter fertilizer at planting; could be used to correct the problem. The residual impacts of K fertilization and …

Evaluation of Cover Crops, Conservation Tillage, and Nitrogen Management in Cotton Production in Southeastern Virginia
… establishment, in-season nitrogen (N) rate, and fertilizer N placement was investigated in two experiments located in coastal plain Virginia and North Carolina. The first experiment examined 1) soil compaction and cotton yield response to strip-tillage compared to no-tillage with a precision …

Strip-till and no-till soybean growth and distribution of roots and soil phosphorus, potassium, and water with broadcast and subsurface-band fertilization
… occurs, is an important management decision as placement can influence the availability to these nutrients to the crop. The objectives of this study were to determine the effect of no-till, strip-till, and P and K rate and placement on soybean [Glycine max (L.) Merr.] root distribution, shoot …

Agronomic management to improve corn productivity under high-yielding environments
… more intensive management systems. Better N placement and timing using the correct source can improve nutrient use efficiency and corn grain yield. For these reasons, the objective of this research was to quantify and predict how agronomic and nutritional management practices can be employed …

Innovations in fertilizer use and agronomic management for greater productivity of corn and soybean
… in greater nutrient demands from the soil and fertilizer, resulting in many soil’s nutrient reserves to be drawn down. With the advent of innovative precision agricultural technologies, fertilizer sources, and management practices, current evolving management practices need to be constantly …

A model of nitrate leaching from agricultural systems in the northern neck of Virginia
… crop rows, enabling consideration of nonuniform fertilizer placement and root growth patterns. VTCROPS models atmospheric, soil and crop subsystems. Atmospheric conditions (rainfall, temperature, solar radiation) may be directly input by the user or generated using a stochastic climatic …

Application of graphene based composites in agriculture
… to feed a constantly growing world population. Fertilizers are an essential component of productive agricultural systems, but their efficiency of use is low due to losses to the atmosphere, soil and waters, which consequently can cause environmental damage. In addition, reaction of nutrients …
