Urine contains about 50 % of the phosphorus (P) and about 90 % of the nitrogen (N) excreted by humans and is therefore an interesting substrate for nutrient recovery. Source-separated urine can be used to precipitate struvite or, through a newly developed technology, nitrified urine fertilizer (NUF). In this study, we prepared (33)P radioisotope- and stable (15)N isotope-labeled synthetic NUF (...

In many parts of the world food security is at risk. One of the biophysical root causes of falling per-capita food production is the declining quality and quantity of soils. To reverse this trend and increase soil fertility soil and plant nutrients have to be replenished. This review provides a literature survey of experiences of using multi-nutrient rock fertilizers for soil fertility enhancem...

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...

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 ...

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...

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...

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...
