Uptake of point source depleted 15n fertilizer by neighboring corn plants
Ground-based active (self-illuminating) sensors make it possible to collect canopy data that are useful for making on-the-go N fertilizer application decisions. These technologies raise questions about plant-to-plant competition for targeted fertilizer N applications. This study evaluated the extent to which fertilizer N applied to an individual corn (Zea mays L.) plant might be intercepted by ...

Growth and nitrogen fixation in high-yielding soybean: Impact of nitrogen fertilization
In high-yielding soybean [Glycine max (L.) Merr.] environments, N uptake during seed-filling may be constrained when the late-season decline in biological nitrogen fixation (BNF) is coupled with insufficient soil N. Three N-fertilization strategies were compared with a control (N0) on soybeans in 2006 and 2007 in a high-yield soybean-maize (Zea mays L.) rotation experiment established in 1999. ...

Safety Showers for the Fertiliser Industry
The fertiliser industry uses extremely hazardous materials in their production processes. Common industry chemicals like anhydrous ammonia can cause burns and inhalation hazards. Others like ammonium nitrate pose a risk of fire and explosion. In 2006 a large explosion at a fertiliser plant in Teeside, UK caused a fire involving mixed gases including hydrogen, nitrogen and ammonia prompting the ...

Solid agglomerate method of NPK compound fertilizer production line
Using monomer basic fertilizers such as: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate monoammonium phosphate, diammonium phosphate, heavy calcium, ordinary calcium), potassium chloride (potassium sulfate), etc. as raw materials, they are crushed to After a certain degree of fineness, the material is agglomerated and granulated in the rolling bed of the drum ...

Green tea catechins applied to susceptible hosts inhibit parasitic plant attachment success
Parasitic plants utilize cell wall degrading enzymes (CWDEs) to penetrate their host plant and attach to host vasculature. Inhibition of CWDEs may confer resistance on susceptible hosts, offering a strategy for parasitic plant control. Here, exogenous application of green tea catechins, which inhibit pectin methylesterase (a CWDE), was used to delay parasitic plant attachment. Texas bluebonnet ...

Nitrogen source and rate effects on the establishment of ‘TifSport’ and ‘Tifway’ hybrid bermudagrass
In the southeast United States, the most popular vegetatively propagated hybrid bermudagrass (Cynodon dactylon x C. transvaalensis Pers. L.) has long been the cultivar Tifway. In recent years, however, southern turf managers choosing cultivars for lawns, golf course fairways, or athletic fields have a newer option: ‘TifSport’ hybrid bermudagrass, also a vegetative selection. Although the use of ...

Equivalency of broiler litter to ammonium nitrate as a cotton fertilizer in an upland soil
Estimates of litter value based on crop yield equivalency to inorganic fertilization may reflect the actual value of litter more accurately than estimates based on its N, P, and K content. The primary objective of this research was to identify a rate of broiler litter that results in cotton lint yield equivalent to inorganic N fertilization and to estimate litter value based on this yield ...

Advantages of granulating compound fertilizer on double roller granulator
The characteristics of the double roller granulator are destined to have a primary low position in the production of compound fertilizer. The advantages of the roller granulator in the compound fertilizer production technology are energy saving and consumption reduction. The extrusion granulation is to granulate the material at room temperature. Compared with other methods, it does not require ...

Production equipment and process analysis of agricultural special NPK fertilizer
NPK production line can process different chemical fertilizers to obtain agricultural special crop compound fertilizer. NPK fertilizer granulation process can be generally divided into: raw material batching, NPK fertilizer mixing, compound fertilizer granulation, particle drying, particle cooling, particle grading, finished product coating and final product packaging. Processing technology of ...

Winter wheat and maize response to urea ammonium nitrate and a new urea formaldehyde polymer fertilizer
Slow release N fertilizers have potential to improve yield and nitrogen use efficiency (NUE) in winter wheat (Triticum aestivum L.) and maize (Zea mays L.). A slow release urea formaldehyde polymer (UFP) was compared with aqueous urea ammonium nitrate (UAN) [(NH2)2CO, NH4NO3] during a 2-yr field experiment in North Carolina. Crops were grown on Candor (sandy, siliceous, thermic Grossarenic ...

Cattle manure application strategies effects on bahiagrass yield, nutritive value, and phosphorus recovery
Animal manure application based on crop N requirements often leaves excess P in the soil because of the differences in the N/P ratio in manures and that required by the plants. This experiment was designed to evaluate the effects of cattle (Bos taurus) manure applied alone or in combination with ammonium nitrate (AN) on bahiagrass (Paspalum notatum Flügge) dry matter (DM) yield, nutritive value, ...

Potato response to a polymer-coated urea on an irrigated, coarse-textured soil
Controlled release fertilizers, especially polymer-coated urea (PCU), have been shown to reduce nitrate (NO3) leaching while maintaining potato (Solanum tuberosum L.) yields, but cost has been prohibitive. A new type of PCU (Environmentally Smart Nitrogen, Agrium, Inc., Calgary, AB) is less costly than previous PCUs, but its effectiveness on potato production has not been extensively studied. A ...

No-till and conventional-till cotton response to broiler litter fertilization in an upland soil: lint yield
The effectiveness of poultry litter as cotton (Gossypium hirsutum L.) fertilizer is not well documented for upland soils in the southern and southeastern United States. The objective of this research was to measure cotton yield response to broiler litter fertilization in contrast to inorganic N fertilization and to quantify yield reduction due to lack of incorporation under no-till and ...

Tillage and fertilizer effects on yield, profitability, and risk in a corn-wheat-potato-wheat rotation
Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract the positive effects of reduced tillage. This study investigates long-term tillage effects (moldboard plow, and deep and shallow chisel plow) and their interactions with N fertilizer input on yields and ...

Evaluation of anaerobic digestate as a substrate for vermicomposting
Vermicomposting is an established process to convert organic wastes into vermicastings suitable for plant growth. This research investigated the vermicomposting of anaerobic digestate with four different ratios of sawdust as a bulking material, for 75 days. The optimum proportion of anaerobic digestate to sawdust was identified as 70:30 based on worm growth and reproduction. Vermicomposting ...
