1、Global crop

The N fertilization data was segmented by 21 crop groups, 13 fertilizer types, and 2 fertilization placements. Comparison analysis showed that our dataset is aligned with previous estimates.

2、What Crops Put Nitrogen into the Soil?

From legumes to grasses, we’ll cover the full range of crops that can help replenish the nitrogen levels in your soil, giving you the knowledge you need to make a positive impact on the environment and your own food production.

3、Towards precise nitrogen fertilizer management for sustainable agriculture

Effective nitrogen (N) fertilizer management is crucial for meeting the growing demand for crop production while maintaining planetary boundaries within sustainable limits.

4、Best Cover Crops for Adding Nitrogen to Soil

One sustainable and environmentally friendly way to replenish soil nitrogen is through the use of cover crops. This article explores the best cover crops for adding nitrogen to soil, how they work, and practical tips for their use.

Seven Plants for Nitrogen Enrichment of Soil: Agronomists’ Tips

Nitrogen plays a key role in forming the fertility of garden soil, as it contributes to the formation of amino acids that are vital for the growth and development of plants. Over time, nitrogen reserves in the soil become depleted; however, in addition to using fertilizers, an effective way to enrich the soil is by growing special nitrogen-fixing plants. This is reported by AgroReview Peas ...

Nitrogen Fertilizers: Types, Benefits, And Application Tips

To fill that shortfall, farmers all around the world rely on nitrogen in fertilizers (mostly synthetic). There are two types of nitrogen fertilizers based on their sources: Organic, or natural. These are N sources, such as manure, compost, blood and feather meal, and fish emulsion, created naturally through fermentation or composting.

Nitrogen Fertilizers for Field Crops

Urea can be used as a starter, broadcast or topdress application and can be used in fertilizer mixes (dry or liquid). Advantages of urea are its high N content (45 to 46%), relatively low cost per lb of N, and rapid conversion to plant-available N.

Which Crops Benefit the Most from Nitrogen Fertilizer?

In conclusion, while many crops can benefit from the application of nitrogen fertilizers, some crops, such as corn, wheat, rice, and soybeans, have particularly high nitrogen demands for optimal growth and yield.

Nitrogen Fertilizer Types, Uses, and Benefits Explained

Nitrogen fertilizers can be divided up into two broad types, natural or synthetic. Natural N fertilizers are derived from nitrogen-rich substances such as manure, fish emulsions, or compost.

High

Perennial and forage legumes, such as alfalfa, clovers, and vetches, are the best crops for companion planting as they can fix substantial amounts of surplus nitrogen under the right conditions. Grain legumes, such as peanuts, cowpeas, soybeans, and fava beans, are also good nitrogen fixers.

Nitrogen fertilizers are indispensable in agricultural production, playing a critical role in crop growth and yield. The following are common crops that rely heavily on nitrogen fertilizers:

1. Wheat: As one of the world’s major food crops, wheat requires substantial nitrogen to support leaf growth and photosynthesis, making it a primary target for nitrogen fertilization.

2. Corn (Maize): A key food and economic crop, corn demands significant nitrogen for stem and leaf development and photosynthesis, positioning it as a major recipient of nitrogen fertilizers.

3. Rice: As a leading global cereal crop, rice relies on abundant nitrogen to sustain stem and leaf growth and photosynthesis, thus requiring intensive nitrogen application.

4. Soybean: This important economic crop needs considerable nitrogen for stem, leaf, and root development, despite its ability to fix atmospheric nitrogen through root nodules.

5. Cotton: Cotton, a vital economic crop, depends on nitrogen to promote vigorous vegetative growth and fiber production.

6. Potato: As both a food and cash crop, potatoes require substantial nitrogen to support tuber formation and above-ground biomass.

7. Tobacco: Nitrogen is essential for tobacco’s leaf expansion and chemical composition, influencing both yield and quality.

8. Rapeseed (Canola): This oilseed crop relies on nitrogen to drive leaf and pod development, directly impacting oil content and yield.

9. Peanut: While peanuts can fix atmospheric nitrogen, supplemental applications are often needed to optimize pod filling and overall productivity.

10. Vegetables: Leafy greens, cole crops, and other vegetables demand high nitrogen levels to support rapid growth and nutritional value.

All these crops exhibit significant nitrogen requirements during specific growth stages. their precise needs vary, necessitating tailored fertilization strategies based on crop type and phenology. Overapplying nitrogen poses environmental risks, such as soil acidification, water contamination, and greenhouse gas emissions. scientific fertilization practices—emphasizing accurate timing, dosage, and integration with organic inputs—are essential to balance productivity and sustainability in modern agriculture.
