In this study, surfactant (hexadecyltrimethylammonium, HDTMA) modified zeolite (clinoptilolite) (SMZ) was used for simultaneous removal of ammonium and nitrate in wastewater, and the sorption properties of SMZ were determined. Results showed that natural clinoptilolite had good affinity for ammonium, but low sorption ability for nitrate, and the ammonium sorption process was well described by ...
Five different N sources were compared with null N treatment to evaluate their performance for N-rich reference plot establishment in corn (Zea mays L.). The sources, including calcium ammonium nitrate (CAN), urea ammonium nitrate (UAN), polymer-coated urea (PCU) and environmentally smart nitrogen (ESN) in 2007 and 2008, and urea (URE), were broadcast or in-soil banded at the rate of 225 kg N ...
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 ...
Ammonium Nitrate Fertilizer Manufacturer - High Temperature Inline Environments Strong Acid/Fluoride Resistant pH Element & High Temperature and Acid/Fluoride Resistant Solid State Reference Junction. Chemically & Thermally Resistant ULTEM & PEEK plastic body housings Application Oriented Engineering and Custom Built to Order sensor increased the lifetime by Two to Five Fold ...
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. ...
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 ...
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 ...
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 ...
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 ...
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, ...

It's important to choose fertilizer for soil and crop There are many types of nitrogen fertilizers, including compound fertilizers processed through the NPK fertilizer production line, so you may want to know which one to use. The key of agricultural fertilization is to choose suitable fertilizer for soil conditions and crops, and determine when to apply fertilizer. In order to avoid over ...
Equipment flow of NPK fertilizer production line 1. Raw material ingredients of NPK fertilizer production line: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, bicalcium, procalcium), potassium chloride (potassium sulfate) and other raw materials are provided in a certain proportion (according to the market demand and ...
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 ...
The equipment flow of NPK fertilizer production line is as follows: raw material batching machine → mixing machine → pulverizer → fertilizer granulator machine → particle dryer → particle cooler → finished product granule coating machine → finished product quantitative packaging machine. 1. Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ...
The drum granulation fertilizer production line is to produce all kinds of fertilizers required by the market according to the formula, which belongs to the fully automatic work, with low energy consumption and less labor, to create high economic benefits. The main equipment of the drum granulation fertilizer production line includes: batching system, rotary drum granulator, mixer, crusher, ...
The raw material route of NPK fertilizer production line of extrusion granulation is extensive. At present, there are more than 20 kinds of materials that have been successfully used in the extrusion granulation machine: ammonium nitrate, urea, ammonium chloride, calcium nitrate, etc. in nitrogen fertilizer, ammonium phosphate, calcium superphosphate, calcium bicarbonate, phosphate rock powder, ...
Drum granulation NPK compound fertilizer production process is the important equipment in fertilizer industry, which can produce special fertilizer according to demand. Compared with single chemical fertilizer, compound fertilizer particle products have more advantages. It can effectively reduce the nitrate content of groundwater, reduce the eutrophication of surface water caused by water ...
Compound fertilizer production equipment, the process of compound fertilizer can be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle grading, finished product coating, and final product packaging NPK fertilizer production line 1. Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ...
