1、Impact of fertilizer and pesticide reductions on land use in China

While chemical fertilizers and pesticides have significantly enhanced crop productivity per unit of land in China, the excessive utilization of these chemicals has led to a range of environmental issues that are not conducive to the sustainable development of China’s agriculture.

2、How Much Nitrogen Fertilizer per Mu is Appropriate?

3、How Much Nitrogen and Potassium Fertilizer Should Be Applied per Mu? The appropriate amount of nitrogen and potassium fertilizers for one mu (approximately 0.067 hectares) depends on crop type, soil conditions, and growth stages.

3、Fertilizer Types and Calculating Application Rates

Phosphate and K 2 O can be land-applied at any time, but normally it is more cost-effective to apply at the same time as N. However, N is more mobile than P 2 O 5 and K 2 O in the soil and should be applied as closely as possible to the time of crop uptake.

4、Calculating Fertilizer Applications : Vegetable : Center for

It can feel overwhelming to calculate fertilizer needs for each of the many crops and fields on your farm. Every year we help growers, both new and seasoned, to make these calculations.

5、How Much Fertilizer Should Be Applied Per Acre?

The fertilizer application rate refers to the quantity of fertilizer needed per unit area (e. g., acre, hectare) or volume, based on desired nutrient concentration and the fertilizer’s nutrient release pattern.

More Land, Less Pollution? How Land Transfer Affects Fertilizer

Reducing fertilizer use is key to curbing agricultural pollution and ensuring food safety. Land transfer enables farmers to obtain a more appropriate production scale, but its effect on the intensity of fertilizer application is not theoretically certain.

Temporal and spatial analysis of fertilizer application intensity and

To thoroughly explore the intensity of fertilizer use and its potential threats to the ecological environment, this study analyzed the environmental risks of fertilizer use from a temporal and spatial perspective based on fertilizer application data in China from 1978 to 2022.

Farmland scale and chemical fertilizer use in rural China: New evidence

Nitrogen, phosphorus, and potassium, as nutrient elements from chemical fertilizer, are the focus of this study, and the dependent variable is the amount of NPK use per mu.

The appropriate amount of chemical fertilizer for one mu of land (approximately 667 square meters) varies depending on crop type, soil conditions, climate, and fertilization goals. Below are recommended fertilization rates for common crops, along with methods for calculating these amounts and key considerations.

1. Identify Crop Type

First, clarify the type of crop being grown. Different crops have distinct nutrient requirements:

• Cereals: Wheat, rice, etc., typically require more nitrogen to promote growth.
• Economic Crops: Cotton, vegetables, etc., may need higher phosphorus and potassium levels to enhance yield and quality.
• Fruit Trees: Apples, peaches, etc., require balanced nitrogen, phosphorus, potassium, and microelements.

2. Analyze Soil Conditions

Soil type and health significantly impact fertilization. Conduct soil tests to assess fertility and pH, which guide appropriate fertilization strategies.

3. Refer to Recommended Rates

Based on China’s Guidelines for Major Crop Fertilization, examples include:

• Wheat: 10–15 kg urea, 15–20 kg diammonium phosphate, 10–15 kg potassium chloride per mu.
• Rice: 15–20 kg urea, 10–15 kg potassium chloride, 15–20 kg superphosphate per mu.
• Corn: 20–25 kg urea, 20–25 kg potassium chloride per mu.

4. Account for Climate and Seasonality

Climate influences fertilization. For example:

• In arid regions, increase nitrogen ratios.
• In rainy areas, reduce nitrogen to avoid runoff.
• Spring and autumn are optimal for fertilization due to faster crop growth.

5. Practical Adjustments

Tailor applications based on real-time conditions. For instance:

• If soil tests show deficiencies, adjust nutrient ratios accordingly.
• Monitor crop growth and soil health regularly to refine strategies.

6. Prioritize Environmental Sustainability

Growing environmental awareness encourages the use of organic fertilizers, which improve soil structure and crop quality. Combining chemical fertilizers with bio-fertilizers or green manure reduces ecological impact.

Fertilization rates per mu must consider crop type, soil, climate, and goals. A balanced approach, informed by science and practical experience, ensures efficient use while minimizing environmental harm. Emphasizing sustainability through eco-friendly fertilizers is critical for long-term agricultural health.
