An inductively coupled plasma atomic emission spectrometry (ICP-AES) method was developed for the determination of phosphorus in fertilizers. Total phosphorus, direct extraction available phosphorus (EDTA), and water-soluble phosphorus, reported as phosphorus pentoxide (P205), in 15 Magruder check fertilizers were measured by ICP-AES, and the results were compared with those obtained by the AOA...

Nitrogen fertilizer use in Wisconsin as anhydrous ammonia, urea-ammonium nitrate solutions, and urea ranged from about 148,000 to 213, 000 tons of N during the 19952000 period (Terry and Kirby, 2001). This amount is similar to that used about 10 years earlier when 170,000 tons of N was used in 1984. However, a substantial materials shift has occurred since 1984 when about 56% of the N used as t...

This paper presents the most important issues relating to the infl uence of mineral fertilizers on both the natural environment and human and animal health. The physiological, environmental and economic impact of fertilizer production and application, resulted from a low assimilation of mineral components by crops, has been described. The research on the development and production of a large an...

Appropriate phosphorus (P) management techniques increase yield and nutritional properties while minimizing environmental concerns. The widespread use of nano-fertilizers (NFs) in agriculture endangers soil plants. It is vital to research the behavior nano-phosphors (nano-P) on plant growth quality, as well their technique interaction with order obtain key ecosystem benefits. With this mind, a ...

Controlled-release fertilizers (CRF) are the newest and most technically advanced way of supplying mineral nutrients to nursery crops. Compared to conventional fertilizers, their gradual pattern of nutrient release better meets plant needs, minimizes leaching, and therefore improves fertilizer use efficiency. In our review of the literature, we found many terms used interchangeably with control...

Nanoparticles are being utilized in agriculture as fertilizers, pesticides, and agrochemical-carriers. Designed to be biocompatible degradable, biopolymer nanoparticles were developed an alternative metallic nanoparticles, though safe-by-design, polymeric must field-tested prior largescale use. Several field studies conducted observe detrimental effects of on plant growth yield using soybean, G...

A study was conducted on clayey soils (vertisols) of southern Telangana zone (India) characterized by low soil organic carbon, available nitrogen and medium phosphorous (P) high potassium (K). The experiment involving seven (N) management practices (T1 to T7) recommended dose fertilizers (RDF) as application, varied rates foliar application nano urea (liquid) laid out in randomized block design...
