1、Sustainable intensification through double

Nitrogen input (kg ha−1), including N added through N2 fixation from legumes and with fertilizers, under sustainable intensified (SI) and common practice (CP) cropping systems.

2、Potato (Solanum tuberosum L.) Responses to Nitrogen Fertilisation in

Reducing the over-use of nitrogen (N) fertiliser and mitigating leaching in highly cultivated agricultural areas have become the top priorities for potato researchers and the industry in the USA. In response, field trials were conducted in 2022 and 2023 at the University of Wisconsin Hancock Agricultural Research Station to explore the effects of different N fertilisation treatments on the in ...

3、Fertilization regimes impact CO

Based on 67 peer-reviewed publications, Yang et al. (2022) found that enhanced-eficiency nitrogen fertilizers (urease inhibitors, NI, coated controlled-release urea) could decrease soil CO2...

Maximizing Nitrogen Fertilizer with NBPT for Better Crop Yields

Farmers who utilize NBPT-treated fertilizers can achieve better results from their nitrogen applications. This not only leads to economic benefits through increased yields but also supports environmentally friendly agricultural practices by minimizing nitrogen runoff and atmospheric emissions.

METHODS OF ANALYSIS FOR NITROGEN COMPOUND IN FERTILISERS (IS STANDERD

The book would describe the standardized procedures and techniques used to determine the nitrogen content in various types of fertilizers, following Indian Standards (IS). (also include Flowchart for laboratory use)

Natural Spray for Bushier Plants

What you need isn’t just more sunlight or fertilizer — it’s a smart, natural way to stimulate bushier growth. While pruning can help, there’s a lesser-known secret: a homemade foliar spray made with natural ingredients that encourages compact, fuller, and leafier plants — especially in herbs, vegetables, and ornamentals.

Mineral fertilizers

Recently, with the object of obtaining better control of pollution, special regulations have been introduced for the application of certain organic fertilizers and manures (e.g. slurry).

Key Granulated Urea 46% – Unikeyterra

Urea fertilizer can be applied successfully to the soil in various ways, as well as in irrigation water or by spraying. It positively affects the stem, green parts and root development of plants. In nitrogen deficiency, plant development slows down and grain and fruit yield losses occur.

Evaluating Maize Genotype Performance under Low Nitrogen Conditions

Summary Maize is the most cultivated cereal in Africa in terms of land area and production, but low soil nitrogen availability often constrains yields. Developing new maize varieties with high and reliable yields using traditional crop breeding techniques in field conditions can be slow and costly.

Phenotyping for Nitrogen Use Efficiency: Rice Genotypes Differ in N

A field experiment was conducted during 2011-12 to evaluate the efficiency of varying nitrogen fertilizer rates on growth and yield parameters, along with nitrogen use efficiency with two nitrogen levels 60 and 120 kg N ha-1 as main treatments and twenty six rice genotypes as sub treatments.

The choice between chlorine-containing and low-chlorine nitrogen fertilizers depends on crop requirements, soil conditions, and environmental factors. Selecting the appropriate nitrogen fertilizer is critical for improving crop yield and quality in agricultural production. Below is a detailed comparison of chlorine-containing and low-chlorine nitrogen fertilizers.

I. Chlorine Content in Nitrogen Fertilizers

1. Advantages of Chlorine-Containing Fertilizers:

• High Nitrogen Content: Chlorine-containing fertilizers typically have a higher nitrogen concentration, which can adequately meet crops' nitrogen demands.
• Rapid Release: Chloride ions in these fertilizers react with soil cations to form insoluble salts, accelerating nitrogen release.
• Improved Fertilizer Efficiency: Chloride ions reduce the absorption of other nutrients (e.g., phosphorus, potassium) by plants, thereby enhancing overall fertilizer utilization.

2. Disadvantages of Chlorine-Containing Fertilizers:

• Soil Structure Impact: Long-term use may degrade soil structure, affecting aeration and water retention.
• Crop Growth Risks: Excessive use can hinder crop growth, causing issues like excessive stem elongation or yellowing leaves.
• Environmental Pollution: Chloride ions can leach into water bodies via rainwater runoff, contaminating surface water.

II. Advantages of Low-Chlorine Nitrogen Fertilizers

1. Environmental Safety: Low-chlorine fertilizers minimize negative impacts on soil and reduce environmental pollution risks.
2. Broad Adaptability: Suitable for diverse soil types, including acidic, alkaline, and saline-alkali soils.
3. Enhanced Efficiency: Improve fertilizer utilization and reduce wastage.
4. Crop-Friendly: Meet nitrogen needs while promoting healthy crop development.

III. Disadvantages of Low-Chlorine Nitrogen Fertilizers

1. Lower Nitrogen Content: May struggle to satisfy high-nitrogen-demand crops.
2. Limited Soil Remediation: Less effective in improving soil quality compared to chlorine-containing fertilizers, requiring supplementation with other nutrients.
3. Higher Costs: Production costs are generally higher than those of chlorine-containing fertilizers, increasing expenses for farmers.

When selecting nitrogen fertilizers, crop requirements, soil conditions, and environmental factors should be holistically evaluated. Generally, low-chlorine fertilizers are preferable for acidic, alkaline, or saline-alkali soils, while chlorine-containing fertilizers may be更适合 when soil conditions are favorable and crops demand high nitrogen levels. Additionally, rational fertilization practices must be emphasized to avoid overuse of chlorine-containing products, which could harm soil health and ecosystems.
