1、Enhanced

Enhanced-efficiency nitrogen fertilizer (EENF), developed to improve synchronization between crop nitrogen demand and nitrogen supply, can guarantee global food security and mitigate nitrogen fertilizer-induced environmental consequences.

2、Enhanced

Open vegetable fields in China are a major anthropogenic source of nitrous oxide (N2O) emissions due to excessive nitrogen (N) fertilization. A 4 yr lettuce experiment was conducted to determine the impacts of controlled-release fertilizers (CRFs) ...

3、Deep Fertilization Is More Beneficial than Enhanced Efficiency

Here, we examine the effects of DF and EEF on crop yield, nitrogen use efficiency (NUE), and nitrous oxide (N 2 O) and ammonia (NH 3) emissions by a meta-analysis of published studies.

This Perspective discusses barriers and opportunities in designing enhanced-efficiency fertilizers and incorporating these alternative technologies into policy- and decision-making.

5、How Much Does Nitrogen Fertilizer Cost? A Comprehensive Guide

In this article, we will explore the cost of nitrogen fertilizer, including the factors that affect its price, the different types of nitrogen fertilizer available, and the benefits and drawbacks of using nitrogen fertilizer in crop production.

Enhanced efficiency fertilizers: Overview of production methods

We hope that the information contained herein, will not only assist farmers in choosing good fertilizers for their crops and soils, but also stimulate further research into sustainable and environmentally friendly production of enhanced efficiency fertilizers.

Enhanced efficiency fertilizer: a review on technologies, perspectives

Some studies, such as that of Xu et al. (2021), estimate that about 1200 kg N/ha of nitrogen may be lost over four crops of corn and wheat, using conventional urea and a dose of 150 kg N/ha for corn and 292 kg N/ha for wheat.

ENVIRONMENTALLY

EEF are a type of fertilizer that allows for regulation of the rate and duration at which the components dissolve into the soil. They can be classified into three main types, including.

Potential of enhanced efficiency nitrogen fertilizers in reducing

Hypothesize that fertilizers with enhanced efficiency technology, such as urea NBPT + Duromide and urea Formaldehyde, can reduce N losses through NH 3 -N volatilization and consequently decrease CO 2 emissions in the ICLS on sandy soil, mitigating the impacts of global warming.

Enhanced

Compared with FP, the cumulative N 2 O emissions were significantly decreased by 8.1%, 38.0% and 42.6% under OPT, CU and CUNI, respectively. Meanwhile, the net benefits of OPT, CU and CUNI were improved by USD 281, USD 871 and USD 1024 ha -1 compared to CN, respectively.

The price of enhanced-efficiency nitrogen fertilizer in Nanjing is influenced by various factors, including brand, quality, packaging, transportation costs, and market supply and demand. Since I cannot provide real-time market price information, the following framework will help you understand how to obtain quotes for nitrogen fertilizer in Nanjing and analyze the factors that may affect pricing.

I. Define Your Needs

Before searching for quotes, clarify your requirements:
